===Appearance===Sylvio has is a handsome young boy with short light brown and blonde hair, styled in layers, and grayish blue eyes. He generally wears the [[Paradise Prep School]] uniform, with his [[Leo Institute of Dueling|LID]] badge pinned to the collar. He briefly wears an outfit in homage to ''Mabuta no Haha'' before his Duel with [[Yuya Sakaki|Yuya]] in the [[Maiami Arc League Championship]]; a teal cape with thin white stripes, a wide-brimmed straw hat, a grey tunic over ash-white leggings, and black elbow-length arm warmers and socks that he wears sandals over. Later, Sylvio wears a [[Turbo Duel]]ing outfit during the [[Friendship Cup]], a yellow jumpsuit with a grey chest portion, white pads, and a teal lining, in addition to a blue helmet with a green visor.

He shows a degree of cunning, pretending to be friends with Yuya in order to steal his "{{[[Timegazer Magician (anime)|Timegazer Magician}}]]" and "{{[[Stargazer Magician (anime)|Stargazer Magician}}]]". After he managed to steal them, he then imprisoned Yuya's friends to force him into a [[Duel]]. Throughout the Duel, he continuously mentioned how he was now the chosen one, able to [[Pendulum Summon]]. Similarly, he claimed his Dueling skills to be perfect when he Dueled Yuto, and constantly looked down on Yuto during their Duel. Sylvio was also shown to be extremely materialistic, valuing only rare cards. This is shown in his Decks which are initially comprised of only [[Parallel Rare]] cards. Furthermore he seemed to be quite shallow with cards, judging them solely for their [[ATK]] or [[DEF]] values and their Level regardless of what effect they may have.<ref name="ep3"/>

Immediately after Pendulum Summoning for the first time, he became fascinated by the newly discovered Summon type. He quickly called it "the best" and went great distances to obtain [[Pendulum Monster]]s. At one point he even claimed he was the first Duelist to Pendulum Summon<ref name="ep54">{{episode|Yu-Gi-Oh! ARC-V|54|ref}}</ref> and bragged about Pendulum to [[Security]] while in the [[Synchro Dimension]].<ref name="ep56">{{episode|Yu-Gi-Oh! ARC-V|56|ref}}</ref>.

In the Japanese version, Sylvio tends to add a large number of English phrases to his speech and speaks rather brashly and rudely, sometimes even addressing himself as "ore-sama" which is a very boastful and egotistical personal pronoun in Japanese. In the English dub, his occasional spouts of English are changed to French and his overall manner is far more posh and polite but still arrogant. In that version, Sylvio has a slight British accent.

[[File:Silvio stealing Yuya's Pendulum Monsters.png|right|thumb|250px|Sylvio steals [[Yuya Sakaki|Yuya]]'s [[Pendulum Monster]]s.]] After class one day, he approached Yuya and his friends, throwing three sucker-tipped darts at Yuya before introducing himself, stating that he was a fan of Yuya and his [[Pendulum Summon]]ing. Yuya was going to show his friends a Pendulum Summon at his own [[You Show Duel School|Duel School]], but Sylvio offered the use of the Center Duel Field at [[Leo Institute of Dueling|LID]]. [[Zuzu Boyle|Zuzu]] wasn't happy about it, but Yuya's other friends all agreed, and Sylvio showed them around the school before he took them to the Duel Field. There Yuya and his friends were met by Sylvio's crew of friends: [[Ootomo]], [[Yamabe]], and [[Kakimoto]]. Sylvio asked to show his crew Yuya's Pendulum Monsters, and Yuya reluctantly showed him his "{{[[Stargazer Magician (anime)|Stargazer Magician}}]]" and "{{[[Timegazer Magician (anime)|Timegazer Magician}}]]." Sylvio promptly swiped them and showed them to his crew, before announcing his intention to keep them. He offered Yuya the chance to Duel to get them back, much to the anger of [[Claude]], who was monitoring Sylvio for Declan. Declan allowed Sylvio to Duel Yuya. Sylvio tossed Yuya some of his [[common]] cards to replace his Magicians, calling them trash cards. To ensure that Yuya would Duel, Sylvio had Yuya's friends placed on top of one of the towers in "[[Prison Tower of Darkville]]," endangering them with the prospect of their perch being damaged by [[Action Card|Action]] [[Trap Card]]s. On the first [[turn]], Sylvio drew "Timegazer Magician," but was instructed by Declan to keep it in his hand instead of playing it right away. Instead, he Summoned "[[Lightning Hoverboard]]" and pursued Yuya, destroying his "{{[[Performapal Whip Snake (anime)|Performapal Whip Snake}}]]" after it was weakened by Action Trap Cards. Yuya continued to play defensively, but to no avail; on Sylvio's next turn he drew a card that allowed him to [[add a card|add]] "Stargazer Magician" to his hand and he proceeded to Pendulum Summon his "[[Dart]]" monsters with Declan's assistance. Sylvio was amazed at the Summon, declaring himself a chosen one.<ref name="ep3" />

[[File:Arc V Silvio and Declan.png|thumb|left|250px|Sylvio Pendulum Summons with help from [[Declan Akaba|Declan]].]]He put Yuya on the ropes with his "Dart" monsters, though Yuya proceeded to create an [[attack]] lock with the card he'd taken from Sylvio - "{{[[Block Spider (anime)|Block Spider}}]]." Sylvio nullified the lock on his next turn by using "[[Cricket Close]]" to [[negate]] "Block Spider" as well as the effects of his own Pendulum Monsters. In response, Yuya increased the [[DEF]] of "Block Spider" to the point that only Sylvio's "[[Ultimate Dart Striker]]" was able to land a hit. Yuya then reclaimed his Pendulum Monsters with "[[Empty Fishing]]" since their effects had been negated and proceeded to Pendulum Summon the next turn himself, using his Pendulum Monsters to allow "{{[[Odd-Eyes Pendulum Dragon (anime)|Odd-Eyes Pendulum Dragon}}]]" to destroy all of Sylvio's monsters, while Sylvio frantically tried to dodge the shockwaves. Yuya then finished Sylvio off with Sylvio's own "trash card," "Block Spider." Despite his loss Sylvio ordered his crew to take the Pendulum Monsters by force but [[Sora Perse]] used a lollipop stick to knock out Sylvio's friends, then Sylvio himself.<ref name="ep4">{{episode|Yu-Gi-Oh! ARC-V|4|ref}}</ref>

After his defeat, he acquired new cards that he tested out against one of his crew. They praised him, calling the cards strong, but Sylvio corrected them, claiming that it was him that was strong and stating that he had all the qualities of a "Perfect Duelist." After he used a few expressions similar to those that Yuya had used his friends wondered if Yuya had rubbed off on Sylvio, but he denied it and vowed he would crush Yuya. He was later seen hanging out with his crew in an abandoned warehouse, waiting for his friends to bring him his favorite food, and chastised his friends for being late.

[[File:Arc V Silvio choking on his food.png|thumb|right|250px|Sylvio chokes on his foodwhen Zuzu arrives to stop him.]]Zuzu, having overheard Sylvio's crew talking about Sylvio's wish to defeat Yuya, decided to try to stop him and barged into the warehouse, surprising him to the point that he choked on his food. Zuzu demanded that he Duel her, continuously denying Sylvio his attempts to speak. When he protested about this she angrily called him a coward and a second-rate Duelist, infuriating Sylvio. Zuzu continued to insult Sylvio, and he furiously agreed to the Duel. Before they could, the door to the warehouse opened, revealing [[Yuto|a mysterious masked figure]], who activated a strange Duel Disk. Sylvio Dueled him instead, mockingly dubbing him "Mr. Mystery" ("Knight" in the Japanese version) for coming to Zuzu's rescue. "Mr. Mystery" placed his entire hand face-down on his first turn and Sylvio seized his chance to bring out "{{[[Mobius the Frost Monarch (anime)|Mobius the Frost Monarch}}]]" then [[Tribute]] it to Summon "{{[[Mobius the Mega Monarch (anime)|Mobius the Mega Monarch}}]]," destroying all five of "Mr. Mystery's" [[Spell Card]]s.<ref name="ep7" />

[[File:Arc V Silvio's jacket pierced.png|thumb|left|250px|Sylvio's jacket pierced by "{{[[Phantom Knights' Spear (anime)|Phantom Knights' Spear}}]]".]]Despite this, "Mr. Mystery" activated his three "{{[[The Phantom Knights of Shadow Veil (anime)|The Phantom Knights of Shadow Veil}}]]" [[Spell Card]]s from the [[Graveyard]]," Special Summoning them as monsters to defend against Sylvio's attack. On his next turn, "Mr. Mystery" used the remaining cards to [[Xyz Summon]], to the surprise of Sylvio, "{{[[Dark Rebellion Xyz Dragon (anime)|Dark Rebellion Xyz Dragon}}]]." The two exchanged insults about how the other failed to live up to their expectations, before "Mr. Mystery" used his [[Xyz Monster]]'s effect to halve the ATK of "Mobius" twice, adding the stolen ATK to "Dark Rebellion" in addition, and reduced Sylvio to 100 [[Life Points]] with a single attack. The force of the impact sent Sylvio flying, despite the match not being an [[Action Duel]]. "Mr. Mystery" questioned Sylvio about LID's connection to [[Duel Academy (ARC-V)|Duel Academy]], holding up an LID badge. Sylvio replied that the badge was worn by all LID students and that he knew nothing of Duel Academy. "Mr. Mystery" turned to leave, but Sylvio refused, pointing out that their Duel was still on. He played "[[Ice Rage]]" in an attempt to defeat "Mr. Mystery," but "Mr. Mystery" negated the Trap using "{{[[Phantom Knights' Spear (anime)|Phantom Knights' Spear}}]]" and inflicted enough damage to win without even turning his back. The spear pierced Sylvio's jacket, pinning him to the wall in shock. "Mr. Mystery" then removed his mask to reveal that he resembled Yuya to the point that Sylvio and his friends believed that he ''was'' Yuya. Sylvio passed out from the stress of the Duel and his crew carried him away in fear.<ref name="ep7" />

[[File:Arc V Silvio dressed in Mabuta no Haha.png|thumb|right|250px|Sylvio cosplays as "Mabuta no Haha" prior to his match with Yuya."]]At the Championship, he accompanied the Course representatives and [[Shay Obsidian|Shay]]. His first Duel was to be against Yuya the next day.<ref name="ep27">{{episode|Yu-Gi-Oh! ARC-V|27|ref}}</ref> Sylvio entered the arena the next day dressed in homage to ''Mabuta no Haha'', proclaiming himself the world's greatest [[Duelist]], and calling himself "Neo New Sawatari." Sylvio claimed that [[Pendulum Summon]]ing would be Yuya's downfall, and pointed out his (unfounded and quickly disproven) grudges against Yuya. They began their Duel, with Sylvio unveiling his new "[[Yosenju]]" [[Monster Card|monsters]]. Yuya Pendulum Summoned next turn and fought back, but Sylvio used his "Yosenju" cards to deny him [[Action Card]]s and add "Yosenju" Pendulum Monsters from his Deck to his hand and Pendulum Summoned "[[Mayosenju Daibak (anime)|Mayosenju Daibak]]." He then [[activate]]d his "[[Dizzying Winds of Yosen Village (anime)|Dizzying Winds of Yosen Village]]" to [[send]] the cards bounced to Yuya's hand back to his Deck instead, and cleared his [[field]] when the self-returning effects of his "Yosenju" monsters triggered his "[[Yosen Whirlwind (anime)|Yosen Whirlwind]]", returning the cards to Yuya's hand and thus to his Deck. Despite his pinch, Yuya simply laughed and [[Set]] his remaining cards, and then turned to find more Action Cards.<ref name="ep31">{{episode|Yu-Gi-Oh! ARC-V|31|ref}}</ref>

[[File:Silvio electrocuted.png|thumb|left|250px|Sylvio electrocuted upon paying the 2000 [[LP]] penalty.]]During the [[Battle Royal]], after the video feed for all of the areas were cut, Sylvio took advantage of his father's influence to barge into Declan's control room and ask what was going on because he wanted to see how far in the tournament Yuya would get. Declan allowed him to stay and offered him a chance to take place in a revival match.<ref name="ep47">{{episode|Yu-Gi-Oh! ARC-V|47|ref}}</ref> Declan explained the situation regarding [[Celina]], [[Shay Obsidian|Shay]] and the invading [[Obelisk Force]] to Sylvio and sent him to assist Celina, Shay, and [[Moon Shadow]]. He arrived in time to use an Action Card to save Moon Shadow. He explained why he was there, boasting that Declan had told him everything, but was then shocked by the intrusion penalty of 2000 LP--a LP—a detail that Declan had ''not'' warned him about. Despite this, he claimed that he'd show them why he was "LID's strongest."<ref name="ep48">{{episode|Yu-Gi-Oh! ARC-V|48|ref}}</ref>

[[File:Arc V Silvio using his new Pendulum Cards.png|thumb|250px|right|Sylvio using his new "[[Abyss Actor]]" [[Pendulum Monster]]s.]]

When [[Yuya Sakaki|Yuya]] asked [[Declan Akaba|Declan]] why they'd been fighting as opposed to the Youth and Pro teams, Sylvio explained that the Youth team were wiped out save for [[Kev Ravenwood|one]], which was why he'd been sent to help. When [[Celina]] revealed herself to be from [[Duel Academy (ARC-V)|Duel Academy]], Sylvio believed her to be a spy and questioned her until [[Moon Shadow]] stepped in to fend him off. Declan then reassured them that Celina was no spy. During Yuya's Duel with Declan, Sylvio filled [[Dennis MacfieldMcField|Dennis]] in on Declan's Dueling and he expressed sympathy for Yuya's loss of [[Zuzu Boyle|Zuzu]].<ref name="ep50">{{episode|Yu-Gi-Oh! ARC-V|50|ref}}</ref>

[[File:Arc V Silvio arrested.png|thumb|left|250px|Sylvio gets arrested by [[Sector Security (ARC-V)|Sector Security]].]]He arrived in the Synchro Dimension with Yuya, Celina, and [[Riley Akaba]], and the group were immediately accosted by [[Sector Security (ARC-V)|Sector Security]], claiming that they were wanted for trespassing in [[Topsiders]]-exclusive areas. Unaware as to what the Sector Security members were referring to and incensed by their rudeness, Sylvio rashly challenged them to a Duel despite Yuya's protests.<ref name="ep55">{{episode|Yu-Gi-Oh! ARC-V|55|ref}}</ref> He was swiftly taken out with a [[One Turn Kill]] and apprehended, and when Yuya Dueled another Sector Security officer, he bragged about [[Action Card]]s and [[Pendulum Summon]]ing, inadvertently alerting the officers to the function of Action Cards. Although Celina defeated her opponent, Yuya was put in a tough spot and more Sector Security officers arrived. Sylvio managed to get free and face-off against them, but fortunately they were saved by [[Crow Hogan (ARC-V)|a Synchro Dimension native]] and his gang.<ref name="ep56">{{episode|Yu-Gi-Oh!

[[File:Arc V Silvio, Selena and Yuya.png|thumb|250px|right|Sylvio, Yuya, [[Celina]], and [[Riley Akaba|Riley]] are invited by [[Crow Hogan (ARC-V)|Crow]] to stay at his place.]]The Synchro user, [[Crow Hogan (ARC-V)|Crow]], invited them to stay at his place until events calmed down, and Sylvio introduced himself as an undefeated Duelist with Yuya as his disciple. Sylvio revealed through his boasts that they were from a different dimension to a confused Crow. [[Frank (ARC-V)|Frank]] and [[Tarren]], two of the orphans that Crow looked after, later returned with stolen food and revealed that they'd seen Yuya and Celina at a café, who Yuya and Celina deduced to be Zuzu and someone named [[Yugo]]. Crow went out to look for them.<ref name="ep57">{{episode|Yu-Gi-Oh! ARC-V|57|ref}}</ref>

[[File:Arc V Silvio and the cook.png|thumb|left|250px|Sylvio tries to convince the cook to give him more food.]]

[[File:Everyone taken away.png|thumb|right|250px|Sylvio and the others are taken away to compete in the [[Friendship Cup]].]]He led them to the roof, where they were cornered by the [[Stomptroopers]]. Sylvio suggested bribing them with rare cards, but Chojiro explained that this wouldn't work on the Stomptroopers Dueling them one-on-three proved difficult for Sylvio, and he fled with Yuya and Chojiro. Trapped on top of a tall tower, Sylvio refused to jump until Chojiro grabbed him and forced him to jump, leaving Yuya to save them. The group were eventually rescued by Gong and Shay, and they linked up with the other escaped Lancers and Commons to swim from the Facility. Unfortunately, [[Jean-Michel Roget]], the Director of Sector Security, had anticipated them and captured Damon's contact, [[Tony Simmons]]. Envoys of the [[High Council]] stepped in to bring the Lancers and the Commons to them, where Declan revealed himself and that he had informed the Council of the Interdimensional War. The Lancers were entered into the Friendship Cup and Yuya was chosen to Duel Jack Atlas in an exhibition match before the start of the tournament. Before being separated from Yuya, Sylvio urged him to show his strength to the Synchro Dimension.<ref name="ep63">{{episode|Yu-Gi-Oh! ARC-V|63|ref}}</ref>

Sylvio watched the Duels on the first day of the tournament, furious that he wasn't being picked but somewhat pacified by the exquisite dinner that he received. He was angry that he still wasn't Dueling on the second day when Yuya Dueled [[Duel Chaser Officer 227]], but was concerned when Yuya was close to losing. He was also shocked to learn from Yuya that the losers in the tournament would be sent to the [[Underground Labor Facility]]. <ref name="ep71">{{episode|Yu-Gi-Oh! ARC-V|71|ref}}</ref> When his name was announced for the Duel against [[Yugo]], he was initially angry, not realizing that he'd finally been picked to Duel.

Yugo responded by bringing out "{{[[Clear Wing Synchro Dragon (anime)|Clear Wing Synchro Dragon}}]]" and locking Sylvio down with two [[Continuous Trap Card]]s and the effect of "Clear Wing". Sylvio was able to back Yugo into a corner using his low-Level "[[Abyss Actor]]" monsters and his "{{[[Abyss Stage Prop - Escape Stage Coach (anime)|Abyss Stage Prop - Escape Stage Coach}}]]" to reduce the ATK of "Clear Wing" to zero. Yugo was able to come back on the next turn, using Yuya's catchphrase to Sylvio's surprise. Yugo was able to destroy Sylvio's monsters and increase the ATK of "Clear Wing" by combining the effect of "Clear Wing" with that of "{{[[Hi-Speedroid Hagoita (anime)|Hi-Speedroid Hagoita}}]]", then attack directly for the win.

[[File:YGO-ARC-V-Ep-73-Img-0012.png|250px|thumb|Sylvio vows to win every Duel in the [[Underground Labor Facility|Underground]].]]Sylvio was taken to the Underground Labor Facility, where the staff that escorted him explained the rules of the place. Upon arriving to meet Gong and Chojiro and learning from [[Lucas Swank]] that one had to win consecutive Duels in order to leave, Sylvio immediately challenged the group to a Duel.<ref name="ep73">{{episode|Yu-Gi-Oh! ARC-V|73|ref}}</ref> However, there is no indication of any duels actually taking place.

[[File:Sawatari_and_Shun_91Sawatari and Shun 91.jpg|thumb|left|250px|Sylvio and [[Shay Obsidian|Shay]] against Underground guards.]]Despite his efforts, Sylvio was unable to leave the facility. He was doing cleanup work with Gong until and noticed [[Shay Obsidian|Shay]] starting a riot. [[Crow Hogan (ARC-V)|Crow]] came down arrived and explained that Duel Academy had invaded New Domino City. Sylvio, Gong, and Shay then got their [[Duel Disk]]s from Moon Shadow, who also informed them that Riley was Dueling alone to protect Celina. Sylvio and Shay decided to go and help while Gong stayed to protect Zuzu from Security. Their escape route was blocked off by an electric gate, forcing Sylvio and Shay to Duel against five guards, who were all defeated by Shay's "{{[[Raidraptor - Blaze Falcon (anime)|Raidraptor - Blaze Falcon}}]]". Lucas arrived on a mining cart to capture them but crashed into the gate. The Stomptroopers arrived and surrounded them but were stopped when Shinji activated the conveyer conveyor belt. Lucas returned to Duel them but was stopped by [[Duel Chaser Officer 227]] and his fellow former officers, allowing Shay, Sylvio, and Moon Shadow to escape.<ref name="ep90">{{episode|Yu-Gi-Oh!

[[File:SylvioStopsSora.png|thumb|250px|Sylvio still considers Sora an enemy.]]

[[file:GongSylvioBlockCommons.png|thumb|250px|left|Sylvio and Gong block the rioting Commons' path.]]After watching the [[Commons (ARC-V)|Commons]] and Sector Security's battle escalate, Sylvio and Chojiro argue about how to get through. Before they come to a decision, Riley's traumatic memories again causes him to join the battle before being calmed by Shay. When they arrived at the Capital Building, the front entrance was blocked by Sector Security. Before they could come up with a plan, Declan arrived and destroyed their Trap Cards with "{{[[D/D/D Duo-Dawn King Kali Yuga (anime)|D/D/D Duo-Dawn King Kali Yuga}}]]"'s effect. After defeating Sector Security, they went get Yuya on Shay's "[[Raidraptor]]s", where they found Yuya, Gong, [[Sam (ARC-V)|Sam]], Frank, [[Amanda]] and Tarren on the bridge to the [[Duel Palace]] about to be attacked by Commons who had mistaken them for retreating Topsiders. Once he was in the stadium, Yuya challenged Jack to a Duel.<ref name="ep95">{{episode|Yu-Gi-Oh! ARC-V|95|ref}}</ref> Sylvio helped the Lancers and Chojiro in fending off Sector Security when they stormed the Duel Palace, defeating a [[Jutte Lord]] with "Abyss Actor - Superstar".<ref name="ep96">{{episode|Yu-Gi-Oh! ARC-V|96|ref}}</ref> He later went out with the Lancers to quell the Commons' riots. He and Gong block blocked off a mob of Commons from continuing their fight against Sector Security with "{{anime|[[Superheavy Samurai Big Benkei(anime)|Big Benkei}}]]", "{{anime|[[Superheavy Samurai Trumpeter(anime)|Trumpeter}}]]", "{{[[Abyss Actor - Funky Comedian (anime)|Abyss Actor - Funky Comedian}}]]", "{{[[Abyss Actor - Pretty Heroine (anime)|Abyss Actor - Pretty Heroine}}]]" and "{{[[Abyss Actor - Sassy Rookie (anime)|Abyss Actor - Sassy Rookie}}]]".<ref name="ep97">{{episode|Yu-Gi-Oh!

They succeeded in stopping the riots as everyone was getting wrapped into the Duel and Sylvio was happy when Yuya won, but disappointed when Gong beat him to naming the [[Pendulum Effect]] of "{{[[Nirvana High Paladin (anime)|Nirvana High Paladin}}]]". The Council broadcasted via holograms their confession of the true purpose of tournament, resigned and disbanded, and dissolved the Topsiders and Commons system. Everyone widely clapped and agreed, and celebrations continued. Sylvio also watched Sora's broadcast and was surprised when Roget took Zuzu.<ref name="ep98">{{episode|Yu-Gi-Oh! ARC-V|98|ref}}</ref>

[[File:LancersLookOverHeartland.png|thumb|250px|Sylvio look over Heartland.]]He and Gong arrived at the ruins of Roget's office and they wondered whether Sora had been buried in the rubble, but Shay arrived and reassured them that Sora would not let that stop themhim. They found Yuya, Crow and [[Jack Atlas (ARC-V)|Jack Atlas]] with Riley and Moon Shadow outside a room where Declan was Dueling Roger. Sora managed to let the Lancers in, where they learned that Roget was using holographic clones to repeatedly Duel Declan. When Declan managed to thwart Roget's loop of Duels, Roger revealed that the Professor, the leader of Duel Academy, was none other than [[Leo Akaba]], Declan's father and the founder of LID and the Leo Corporation. Declan managed to throw off the accusations against him and Roget retreated. Sylvio witnessed Yuya and Zuzu's reunion and Roget's attempts to kill them all by dropping the City into the void between dimensions. After Roget and Zuzu were both sucked away, Sylvio came to Gong and Shay's aid when Yuya was beginning to get sucked in too, but their efforts were in vain and all four Lancers were sucked into the portal. They came to in a ruined city, and Sylvio questioned whether New Domino had been destroyed. Shay informed them that they were in fact in his home: [[Heartland City (ARC-V)|Heartland City]] in the [[Xyz Dimension]].<ref name="ep99">{{episode|Yu-Gi-Oh! ARC-V|99|ref}}</ref>

[[Shay Obsidian|Shay]] left Sylvio, [[Gong Strong|Gong]] and [[Yuya Sakaki|Yuya]] to go and seek out the base of [[the Resistance]], but he did not return, so the three [[Lancers]] wandered the ruins of Heartland. Sylvio was starving and hallucinated an oasis, but when admonished for it by Gong, legitimately spotted a woman gathering water and food. The woman fled upon seeing their [[Duel Disk]]s, so the Lancers attempted to return her supplies, though Sylvio had to be persuaded not to have some. They witnessed a man being [[Human Sealing Technology|sealed]] into a card by three [[Duel Academy (ARC-V)|Duel Academy]] students and found the woman's house, eventually managing to convince them to take their food back. Sylvio was extremely tempted by the food and he argued with Gong over eating it, until Gong's growling stomach and the generosity of the woman's sons allowed them to have some. The woman also explained that the Resistance had been wiped out for some time. The three Duel Academy students returned, but they were stayed from sealing the group when they noticed that the Lancers were Duelists. Yuya, Gong and Sylvio defeated them all using Yuya's "[[Smile World (anime)|Smile World]]" and a [[Pendulum Summon]], also succeeding in entertaining the family. Sylvio tried to use the Duel Academy Duelists' Duel Disk to seal them into cards, but Yuya stopped him. Sylvio protested that they couldn't just let the students flee and was proven right when the students did flee, but he and the Lancers saw the students sealed into cards by [[Kite Tenjo (ARC-V)|Kite Tenjoa Duelist]] with a [[Galaxy-Eyes Cipher Dragon (anime)|dragon]] who then challenged the Lancers to a Duel.<ref name="ep100">{{episode|Yu-Gi-Oh! ARC-V|100|ref}}</ref> [[File:SylvioYuyaPose.png|thumb|left|250px|Sylvio accepting Kite's challenge.]]Sylvio accepted his challenge, and Gong joined as well in order to prove that they were not enemies. The Duelist, who Yuya identified as Kite Tenjo, concluded that they were invaders after seeing Sylvio use an Action Card. Sylvio tried to prevent Kite from [[Xyz Summon]]ing his dragon, but Kite managed to counter his attempts and call out "[[Galaxy-Eyes Cipher Dragon (anime)|Galaxy-Eyes Cipher Dragon]]", defeating Sylvio and Gong.<ref name="ep101">{{episode|Yu-Gi-Oh! ARC-V|101|ref}}</ref> Sylvio and Gong watched Yuya Duel Kite, who was able to counter some of Yuya's tactics from learning through the Duel with Sylvio. Kite learned that Action Cards can be used for defense, and Sylvio tried to explain how they could be used before being silenced. Yuya Xyz Summoned "[[Dark Rebellion Xyz Dragon (anime)|Dark Rebellion Xyz Dragon]]", [[Shay Obsidian|Shay]] and [[Alan|two]] [[Saya Sasayama|other]] Resistance members interrupted the Duel and Shay clarified that Yuya, Sylvio and Gong were his comrades. While Kite was still in doubt, Shay assured Kite that Yuya wanted to stop Duel Academy as much as they did, asking him to trust Yuya like he did. Upon hearing Yuya's last name and the female Resistance member's plea to return, Kite refused before taking his leave of them.<ref name="ep102">{{episode|Yu-Gi-Oh!

Upon witnessing Alan mistaking Yuya for Yuto, he asked who Yuto was (as he had never learned his name when they Dueled). Gong explained to Sylvio that Yuto was someone [[Zuzu Boyle|Zuzu]] had met a few times who looked like Yuya. Sylvio learned of the second massive attack that Duel Academy had launched that had wiped out most of the Heartland civilians and the Resistance members. He, Yuya and Gong were surprised and shocked to hear of [[Yusho Sakaki]]'s visit to the dimension as well as the fact that Yusho was well-known in Heartland.<ref name="ep103">{{episode|Yu-Gi-Oh! ARC-V|103|ref}}</ref> Shay later met up with Kite again, and as they prepared to Duel, Sylvio and Gong arrived to stop them, but were unable to do so. During the Duel, Sylvio explained Action Cards to Alan and Saya. Yuya arrived, and also failed to stop the Duel, but Shay began to use Action Cards, calling them the power of his comrades, the Lancers. Sylvio and Gong explained the effects of each card he used, and they realized in shock that Shay's final card had been "[[Take Flight (Action Card)|Take Flight]]", which he couldn't use at the time. They were surprised when Yuya revealed that Yuto was residing inside him. Kite defeated Shay and prepared to seal him in a card, but Saya begged him not to before revealing that she had witnessed [[Lulu Obsidian]]'s kidnapping. This revelation shocked Sylvio, and Kite reluctantly complied before leaving again.<ref name="ep105">{{episode|Yu-Gi-Oh!

Shay arrived and decided to split the Lancers into two groups to find Saya. While they were searching through Heartland, Gong and Sylvio heard an eplosion, and they found the unconscious bodies of Alan and Saya at the source. Sylvio asked the [[Gloria Tyler|female]] [[Grace Tyler|Duelists]] that had defeated the two Resistance members if they were from Duel Academy. When the Duelists asked who he was, Sylvio revealed he and the others were Lancers, and he and Gong Dueled the Tyler sisters.<ref name="ep107">{{episode|Yu-Gi-Oh!

Sylvio criticized Sanders' teachings when he told his students to follow rules despite having five some part of them cardedRiley. He told Yuya not to get lost now also learned that Z-ARC will resurrect and take on Crow and Moonthe world will be at risk again if they don's enemyt do it. Sylvio was happy that "Andabatae's" effects were negated but annoyed that Battle Beast used "surprised when Gong summoned a [[Gladiator Beast Assault FortSuperheavy Samurai Steam Train King (anime)|new monster]]"and rode it. He was surprised when Battle Beast used then ran out of the effect of way before "Tamer EditorTrain King" to destroy itselfcould run over him.<ref name="ep121ep143">{{episode|Yu-Gi-Oh!

He is later seen watching Yuya's Duel against Jack with Gong, [[File:Jack Helps Gong Up.png|thumb|leftAura Sentia|Sylvio along with Jack helps Gong to stand.Aura]]He was surprised when Yuya revealed that Battle Beast doesn't really want to fight. When Yuya revealed the similarities between him and Battle Beast, Sylvio realized that when Crow drove him out of the jungle he became more aggressivekids from [[You Show Duel School]]. When the students wanted their instructor sealed into a card, Sylvio wondered if people's lives mattered to them. He was worried when Yuya was about to be defeated by the effect of "Gladiator Beast Tamer Editor". He was surprised and Gong discussed how Jack protected countered Yuya from the second "Fort", but angry that Jack was sacrificing himself as he looked at Crow's cardattack and summoned a [[Red Giant|new monster]]. When Jack destroyed everything with the effect of <ref name="ep146">{{animeepisode|Yu-Gi-Oh!

Sylvio reminded him that he destroyed wondered why Yuyadidn's monsters too. When Battle Beast brought out t Pendulum Summon "[[Gladiator Beast Great FortressPerformapal Duck Dealer]]", Sylvio wondered where he wentbut was pleased when Yuya did so. Sylvio He was surprised amazed when Yuya made a comeback against Declan's "Andabatae" ATK surpassed "Tyrant'[[D/D/D Doom King Armageddon (anime)]]s". Sylvio wondered what Yuya was planning after Special Summoning surprised when Declan summoned "[[Level 1D/D/D Super Doom King Purple Armageddon (anime)|D/D/D Super Doom King Purple Armageddon]] ", "[[Pendulum MonsterD/D/D Super Doom King Bright Armageddon (anime)|D/D/D Super Doom King Bright Armageddon]]s but got hit by a paintball from ", and "[[Performapal ShieldrummerD/D/D Super Doom King Dark Armageddon (anime)|D/D/D Super Doom King Dark Armageddon]]". When Yuya went for a direct attack, Sylvio was worried because of the of <ref name="Great Fortress". He was surprised when ep147">{{animeepisode|Yu-Gi-Oh! ARC-V|147|Gladiator Beast Gyzarusref}}" came out </ref> He was worried when Yuya took huge damage from the fortress with 3000 ATKfour dragons being destroyed. When Battle Beast Special Summoned Sylvio was amazed when Yuya used the effect of "{{[[Odd-Eyes Wing Dragon (anime)|Gladiator Beast Augustus}}Odd-Eyes Wing Dragon]]", Sylvio was happy that its ATK was stuck at 1000to destroy all of Declan's monsters. He was happy that Battle Beast no longer had any monsters in his fortress and that then wondered why Yuya still had attacked "PararhinoDarkness Armageddon" due to winits ATK being higher than "Wing Dragon". Sylvio thought it was the end but was surprised that Battle Beast still had a monster. He and Gong wondered what cheered Yuya did on when he activated used the effect effects of "Guard Dance[[Odd-Eyes Xyzgate]]" and "[[Wonder Chance]]"to give "[[Odd-Eyes Rebellion Dragon (anime)|Odd-Eyes Rebellion Dragon]]" additional attacks. When Sanders thought Yuya will loseHowever, Sylvio asked him didn't he learn anythingwas surprised when Declan survived the attacks and happy when Yuya was able to Pendulum Summon again. When Yuya mentioned and Declan were collecting [[Action Card]]s due to the people Battle Beast cardedeffect of "[[Performapal Five-Rainbow Magician (anime)|Performapal Five-Rainbow Magician]]", Sylvio looked and Gong were surprised at Crowhow Declan was stealing Yuya's cardshine. They were also worried when Declan was catching up to Yuya and Sylvio was pleased that Yuya was able to get five first. He told was pleased when Yuya they would catch up won and was transported to the field by Ray to him as he and Jack helped Gongwitness Zuzu's revival.<ref name="ep122ep148">{{episode|Yu-Gi-Oh!

Sylvio is shown to greatly respect and admire [[Declan Akaba|Declan]]'s Dueling abilities as shown when he bragged about how he was well known for his multiple Summoning methods to [[Dennis MacfieldMcField|Dennis]]. Declan in return, is shown to have faith in Sylvio's abilities as shown by how he entrusted Sylvio with the task of taking [[Yuya Sakaki|Yuya]]'s [[Pendulum Monster]]s, had him test a "[[Yosenju]]" Pendulum Deck, and had him become a [[Lancers|Lancer]] to aid the others during the invasion by the [[Obelisk Force]]. Declan also taught Sylvio how to Pendulum Summon. It is implied they have some prior connection because there is no other reason given as to why Declan would choose him to steal Yuya's cards.

When [[Crow Hogan (ARC-V)|Crow]] and his gang saved Sylvio and the other [[Lancers]] from [[Security]], Sylvio showed sincere respect and gratitude to Crow. While Crow found Sylvio's claims about the Lancers and [[Standard Dimension]] strange, he didn't seem to dislike Sylvio. After Sylvio defended Crow from a large Security guard which allowed Crow and his friends to escape, they seem to have gained respect for each other, giving each other a thumbs up. When  Despite being initially angry that Crow had sacrificed himself to save him, when Crow was sealed into a [[Crow Hogan (ARC-V card)|card]] by [[Battle Beast]], Sylvio grew extremely upset and immediately ran to save his card when Battle Beast was about to step on it, showing how much he cares for and respects Crow. Due to Crow's actions Sylvio came to recognize the importance of others sacrificing themselves for those they care about, and behaved more emotionally than usual. He was horrified when he lost the card, but overjoyed when Crow was freed from the card and returned to Duel Z-ARC with him.

Despite While not getting along at first, Sylvio and Gong grew to be friends and allies as part of the Lancers and mutual friends of Yuya. They have been each other's most frequent tag-team partners in Duels. Gong later entrusted his Duel Disk and Yuya's pendant to Sylvio, believing that he could get through to Yuya.

Sylvio's Deck has changed drastically over the course of the anime. He has , having used four completely different Decks, but according to [[Katsumi Ono]], he will use an "[[Abyss Actor]]" Deck for the rest of the series.<ref>{{citeweb|url=https://stardustjunction.wordpress.com/2015/03/13/anime-news-interview-with-director-ono-easter-eggs-etc/|title=Anime News: Interview with Director Ono, Easter Eggs etc}}</ref>

Sylvio initially plays a '''"[[Dart]]" Deck'''. All the cards in this Deck (besides the "Magicians" he stole from [[Yuya Sakaki|Yuya]]) are [[Parallel Rare]]. His strategies focus on his "Dart Striker" monsters powering one another up through their effects, which receives a strong boost from his use of [[Pendulum Summon]]ing during his Duel with Yuya.

Sylvio uses a '''"[[Yosenju]]" Deck''' during the [[Arc League Championship]]that includes [[Pendulum Monster]]s. Sylvio focuses a lot of his strategies on swarming the field with his "Yosenju" monsters to accumulate counters on his "{{[[Yosen Training Grounds (anime)|Yosen Training Grounds}}]]" which he uses to gather the necessary cards for his strategies. He also uses a lockdown comprised of "{{[[Mayosenju Daibak (anime)|Mayosenju Daibak}}]]", "{{[[Yosen Whirlwind (anime)|Yosen Whirlwind}}]]" and "{{[[Dizzying Winds of Yosen Village (anime)|Dizzying Winds of Yosen Village}}]]", returning his opponent's cards to their Deck, putting them in a pinchand bypassing the ability of Pendulum Monsters to revive themselves. This Deck, unlike his previous two, is not comprised of Parallel Rare cards.

Sylvio's final Deck is an '''"[[Abyss Actor]]" Deck''', first used during the invasion of the [[Obelisk Force|Fusion Dimension Warriors]]. It focuses on [[Pendulum Summon]]s ing and is supported by the "[[Abyss Script]]" [[archetype]] of [[Spell Card]]s. During the Heartland City arcthird season, he also demonstrates a focus on restricting the opponent's [[Extra Deck]]. Like his previous "Yosenju" Deck, it is not composed of Parallel Rare cards. While Sylvio is never shown using any other Summoning methods with this Deck, he is shown to have a substantially sized-Extra Deck during his Duel with Yugo, implying he has access to others.

Sylvio had a number of cards he offered to [[Yuya Sakaki]] as "compensation" for taking his "{{[[Stargazer Magician (anime)|Stargazer Magician}}]]" and "{{[[Timegazer Magician (anime)|Timegazer Magician}}]]". He described them as "trash cards" that fit Yuya perfectly. Yuya chose to add "{{[[Block Spider (anime)|Block Spider}}]]" to his Deck as a result.<ref name="ep3" />

During his escape from the [[Facility (ARC-V)|Facility]], Sylvio managed to grab a pile of rare cards from [[Chojiro Tokumatsu]]'s collection that were used as a distraction. The only shown card was "{{[[Dark Mirror Force (anime)|Dark Mirror Force}}]]".<ref name="ep62" />
