He attended [[Duel Academy]] and was put in the [[Slifer Red]] Dorm, the dorm with the least privileges, due to his poor grades in the entrance exam. As time goes on, he becomes the academy's best Duelist and saves the world and the academy from many threats such as the evil [[Kagemaru]], The Light of Destruction possessed [[Sartorius]], the deranged and manipulative [[Yubel (character)|Yubel]], and finally the malicious spirit [[Nightshroud]]. After three years, he graduates from Duel Academy and pursues his own journey to improve himself.

===Appearance===

[[File:Judai Linework.jpg|thumbnail|180px|left|Jaden's design incorporates multiple layers of clothing and a wide range of expressions. Depicted here is the [[Duelist]] in full [[Slifer Red]] regalia from front, side, and rear alongside views of his head from different angles.]]

Jaden's usual outfit consists of the standard [[Slifer Red]] uniform, unbuttoned, and a black shirt underneath. In the fourth season, the normal Slifer Red white pants were replaced by dark jeans. A [[Main Deck|Deck]] box is strapped above his waistline, largely hidden beneath the lower rim of his jacket. In the first episode he is seen wearing a high school uniform similar to the one worn by [[Yugi Muto]], though colored black instead of blue. He also wore a KaibaCorp Duel Disk on his left arm for his entrance exam Duel. His brown eyes are positioned directly beneath the bangs of the layer closest to his face. After joining Duel Academy, he carries an [[Academia Disk|Academy-issued Duel Disk]] on his left arm.

In the fourth season, Jaden is seen with his new look, but he is still easy to identify from the past seasons. He comes back with longer hair, a longer, darker Slifer Red jacket, darker pants and, since he fused his soul with Yubel in the third season, occasionally manifesting its power to protect himself in the form of his eyes glowing the same bichromatic scheme Yubel's did. His eyes have also been redesigned. His Duel Disk is now fully customized with red outlines on it representing his dorm, though otherwise it looks the same (although the difference is very noticeable).

In the Japanese version, Jaden rarely uses [[wikipedia:Japanese honorifics|honorifics]], and his speech pattern could be considered rude as a result, similar to [[Joey Wheeler]]'s.

===Personality===

Jaden shows little interest in areas outside of Dueling, which extends to his classes. When he chooses to attend them, he generally falls asleep. Despite his low grades, he is still regarded as one of Duel Academy's best Duelists. However, this attitude eventually shows itself as one of his greatest flaws, and causes him to be targeted by [[Mr. Stein]]. He shows a lack of knowledge in areas outside of Dueling, even showing in [[Yu-Gi-Oh! GX - Episode 015|one instance]] that is unaware of what the term "fiancee" means, and forgetting that the holographic water will not drown him in [[Yu-Gi-Oh! GX - Episode 038|another]].

Jaden also seems ignorant of the dislike that other individuals have for him, as despite the obvious tension between the two, he considers himself to be good friends with [[Chazz Princeton]]. His carefree attitude and lack of thought get him into trouble occasionally, such as when he [[Yu-Gi-Oh! GX - Episode 101|handed]] the [[Satellite Keys]] to [[Sartorius]] and still expected the latter to Duel him before using them. He occasionally shows signs of intellect, such as determining that [[Titan]]'s [[Shadow Game]] was a fake, and figuring out that both [[Brier]] and [[Beauregard]] were the [[Duel Giant]] on another occasion.

===Etymology===

==Biography==

===History===

As a child, Jaden loved ''[[Duel Monsters]]''. His favorite card was "[[Yubel (anime)|Yubel]]," which was a gift from his father. Both his parents were rarely at home, as they were busy working. As a result, Jaden spent many of his days playing Duel Monsters with neighborhood children. However, whenever Jaden played "Yubel", something horrible would happen to his opponent. One of them, [[Osamu]], fell into a coma. The [[Yubel (character)|spirit]] of the "Yubel" card was overly protective of Jaden, and punished his opponents. After that incident, no one wished to Duel Jaden, as they feared for their safety.<ref name="ep131">{{episode|Yu-Gi-Oh! GX|131|ref}}</ref>

====Society of Light====

Jaden has begun his second year at Duel Academy. Unaware of new student [[Aster Phoenix]]'s status, Jaden Duels him, eager to teach a new student about Dueling. During the Duel, Ms. Dorothy reveals that Aster constructed the Deck out of eight packs of cards he purchased that morning. Jaden attempts to give him advice, which Aster pretends to take. Aster is not impressed by Jaden, and leaves after being defeated. Later, after the Duel, Syrus Truesdale realizes who Aster really was, and Jaden is eager to have a rematch with Aster when the latter is using his true Deck.

Sometime later, Jaden has just recently finished a Duel with Bastion Misawa in the Duel Arena, using "Elemental Hero Shining Flare Wingman" to destroy "[[Water Dragon (anime)|Water Dragon]]" to get the win. That night, the group gathers inside the Slifer Red dorm to watch Zane Truesdale's next Pro League match. Finding out that Zane's opponent will be Aster Phoenix, Jaden is eager to see what Aster's actual Deck consists of. To everyone's surprise including Zane's, Aster reveals that his Deck has an "Elemental Hero" theme, similar to Jaden's. However, when Aster fuses Elemental Heroes "Avian" and "Burstinatrix", he does not Fusion Summon "Elemental Hero Flame Wingman", but "[[Elemental Hero Phoenix Enforcer (anime)|Elemental Hero Phoenix Enforcer]]". To his friends' amazement, Jaden was unaware that this Fusion Monster even existed. Aster counters nearly every move Zane makes and even causes him to take damage from "Power Bond". The Duel ultimately ends with Aster the winner, much to the shock of all of Duel Academy.

Aster unveils his "Destiny Heroes" and Jaden's "Elemental Heroes" can't seem to compete. Despite the "Destiny Heroes" relatively low attack points, their effects push Jaden into a corner, as Aster uses "[[Misfortune (anime)|Misfortune]]" to deal damage while continuing to place [[Clock Counter]]s on "Clock Tower Prison". On the turn that the fourth Clock Counter is placed, Jaden would be able to deal enough damage to win. However, "Clock Tower Prison" renders Aster immune to damage when it has enough Counters. Jaden plays "[[Fusion Gate (anime)|Fusion Gate]]" and because "Clock Tower Prison" was destroyed, Aster can Summon his ultimate monster - "[[Destiny Hero - Dreadmaster (anime)|Destiny Hero - Dreadmaster]]", whose ATK are equal to the sum of the attack points of the other "Destiny Heroes" on the Field.

Aster explains his past. His father was a card designer for Industrial Illusions, who designed the "Destiny Heroes" himself. One day, Aster came home to find his father dead (kidnapped in the dub). The person who did it also took one of the "Destiny Hero" cards, which was known to be the most powerful among them. Aster's vigilante activity is centered around stopping crime to find the person who took his father from him, as he would be able to identify them by their possession of the stolen card. His "Dreadmaster" negates the effect of Jaden's "[[Elemental Hero Thunder Giant (anime)|Elemental Hero Thunder Giant]]" and wins Aster the Duel with its attack. Jaden falls to the ground, his cards flying about, and they turn blank as he falls.

Later, Jaden Yuki is stranded in a boat when a comet hits. Afterwards, he is transported into [[Neo Space (location)|Neo Space]], a Duel Monsters Spirit World that represents and protects the delicate balance between Light and Darkness. Within this Limbo, Jaden ends up on a planet called Dolphina (which apparently is an uncharted planet neighboring Jupiter), where he is greeted by a dolphin-like creature named "Aquos" (who is later revealed to be the [[Neo-Spacian Aqua Dolphin (anime)|spirit]] of "[[Neo-Spacian Aqua Dolphin (anime)|Neo-Spacian Aqua Dolphin]]"), who explains that "[[the Gentle Darkness]]" is in danger of being obliterated by a mysterious "Dark Light", and only Jaden Yuki is able to fight off this entity and save the universe.

Just then, an unusual Duel Robot sent by this "Dark Light" arrives, and Jaden must defeat it in a Duel, using cards salvaged from a satellite. He's shocked when he can see the cards he's holding, and even more shocked when he discovers that the cards were contained within a KaibaCorp satellite, which was carrying cards he'd designed for a global contest held by Seto Kaiba a few years ago, and Jaden figures out that he was the winner.

The Sarinas take an early advantage in the Duel, due to the fact that Aster refuses to cooperate with Jaden, while Jaden's moves are more about luck than strategy. Furthermore, the full moon behind Sarina's "[[Full Moon Mirror]]" seems to wane into a new moon with every monster that is destroyed, and once "Full Moon Mirror" gains its tenth Full Moon Counter, Sarina declares that the true test has now begun.

Sarina 1 unveils her strongest monster: By Tributing "[[Magic Mirror Spirit Asogi]]" and "[[Magic Mirror Spirit Nayuta]]" she Summons "[[Dark Creator (anime)|Dark Creator]]" to the field and multiplies her monster tenfold, thanks to a Field Spell Card called "Infinite Fiend Mirror". After stating that only the Chosen Duelist can destroy her army of "Dark Creator" monsters, she attacks, but Jaden and Aster barely manage to survive her onslaught, because of Aster's "[[Elemental Recharge (anime)|Elemental Recharge]]". However, as Sarina ends her turn without a direct attack, Jaden comes to realize that "Dark Creator" and the "[[Dark Creator Token]]s" that were recently summoned cannot attack directly. Even though Aster manages to launch a counterattack with "[[Destiny Hero - Dasher (anime)|Destiny Hero - Dasher]]", Sarina's "Dark Creator" has another surprise: it cannot be destroyed by battle. However, Jaden is able to use the effect of "Dasher" in the Graveyard to Special Summon his newest "Neo-Spacian" monster, "[[Neo-Spacian Dark Panther (anime)|Dark Panther]]", and use it in a combo that brings out "[[Elemental Hero Dark Neos (anime)|Elemental Hero Dark Neos]]". "Dark Neos" is able to negate the effects of "Dark Creator", which, after "Dark Creator" is destroyed, undoes the effects of "[[Infinite Fiend Mirror (anime)|Infinite Fiend Mirror]]". After the Duel, Sarina urges Jaden and Aster to save her brother from the control of the light.

Jaden asks what that is and Syrus asks if Jaden never watches the news. Syrus says it's a small, isolated country, but they've launched SORA, a laser satellite that could burn the world down. He says he did hear that their first prince is a big fan of ''[[Duel Monsters]]'' though. He had announced on TV that he had passed his test to become a professional Duelist. Jaden says that now he know who his first opponent is. Jaden runs towards the plane, where Ojin is about to descend from with three bodyguards and Linda. Ojin tells his bodyguards to relax - the kid appears to be a challenger. Jaden is about to challenge Ojin when Sartorius appears, zapping Jaden with energy by touching his shoulder. Sartorius offers Jaden his apologies and says that Ojin's existence is unrelated to his destiny, as Chazz and Alexis arrives behind him. Sartorius declares that because of that, he will be Ojin's opponent. Jaden asks who decided that and Sartorius responds that the heavens did. Jaden asks him to hold on and Sartorius approaches Ojin, asking for a Duel. Jaden points out that he was the one who found him first and asks to Duel instead. Ojin asks which one of them is connected to the "D" cards. Jaden asks if he means the "Destiny Heroes" and Sartorius says that that would be him. Ojin concludes that Sartorius will be his opponent then. Sartorius says he is delighted and grateful. Jaden asks how Sartorius is linked to the "Destiny Heroes", insisting that that would be Aster. Sartorius wins easily without even using one turn and he obtains the controls to [[Misgarth]]'s [[SORA (satellite)|satellite]]. Jaden wonders what kind of Duels are in store for the rest of the tournament.

The Genex Tournament is in full swing, but Jaden and his friends are in a slump—especially Jaden, since no challengers have approached him for a Duel. Meanwhile, [[Maximillion Pegasus]] and [[Chumley Huffington]] have arrived at Duel Academy from [[Industrial Illusions]], searching for a stolen copy of the strongest [[Egyptian God]] Card, "[[The Winged Dragon of Ra (anime)|The Winged Dragon of Ra]]". It is later discovered that a man named [[Franz]] has stolen the card, and then sneaked his way into the Genex Tournament. When Franz finds them, he challenges Pegasus to a Duel, stating that the winner will claim the stolen card. However, it's Jaden who ends up Dueling Franz, and must ultimately find a way to free "Ra" from a confining Field Spell that forces Ra to use its powers against its will. Following Franz's defeat, Pegasus explains to him that everyone can learn a lot from defeats and mistakes, while revealing the spot where his Millennium Eye once rested (before being stolen by Yami Bakura). When Pegasus offers Franz back his position in Industrial Illusions, Franz readily accepts, and returns to Industrial Illusions with Pegasus and Chumley.

Later, Jaden Duels [[Orlando]] as part of the Genex Tournament. Orlando is a Kabuki stage actor and Professional Cosplay Duelist. Jaden defeats Orlando and reminds him Dueling is more about fun than it is about performing.

The Ojama Trio asks if Jaden can help Chazz; and feel that if they returned to him at this point, he would just throw them away again. Jaden offers to put the Trio in his Deck for his Duel with Chazz, which they accept, being excited about being able to fight beside Heroes. The next, day, Chazz and Jaden meet outside the main entrance to Duel Academy's main building, with Jaden bringing Chazz's old black uniform along with him. Chazz reaffirms his devotion to the Society of Light, but mentally feels strange at seeing the jacket, as some of his former memories return to him. Chazz dominates the early stages of the Duel, and Jaden is reduced to 400 Life Points. Eventually Jaden uses an "Ojama" combo to defeat him and reminds Chazz that he only listens to himself and ultimately removes him from the control of the Society of Light.

Elemental Hero Neos manifests before Jaden and explains that the source of every battle is a confrontation between light and dark. Neos says Jaden is the only one with the power of "gentle power of the Darkness of Justice" to save the world from The Light of Destruction. Jaden challenges Sartorius to a Duel for the satellite keys. Sartoruis states he has no reason to Duel Jaden, since he's already given up his key. Sartorius sends a beam of light at the keys to retrieve them, but the beam is blocked by a multicolored beam from space. Neos is protecting the keys. This forces Sartorius to Duel Jaden for them. Jaden gains an early advantage, reducing Sartorius to 300 Life Points with "Shining Flare Wingman". However, Sartorius activates "[[Light Barrier (anime)|Light Barrier]]" which surrounds the field, suppressing Neos' power. Sartorius retrieves the keys and influences Prince Ojin once more, giving him the keys and telling him to run an activate the satellite. With the keys gone, the hand holding Aster lowers towards the lava. Hassleberry runs in and barely manages to save Aster's life. Ojin rushes off to activate the satellite, and Hassleberry chases after him with Linda, leaving Syrus Truesdale to tend to Aster and support Jaden. Sartorius' "Light Barrier" card negates the effects of all non-Arcana Force monsters, allows Sartorius to choose which effect all such monsters get, and add the ATK of any monsters that either player destroys to their Life Points. During the Duel, Jaden has a vision of his own future, with himself standing in a desert. He's attacked by a shadowy armored figure, but this gives him confidence, as this future implies that the world is not destroyed, and that he wins against Sartorius, despite the fact that this implies a bleak future for him. When Jaden summons "Elemental Hero Neos", it tells him that if he wins the Duel, he may be able to stop the satellite. Jaden manages to destroy "Light Barrier", allowing Neos to leave the area. After attacking directly with "Elemental Hero Glow Neos", its Duel Spirit leaves with that of Hassleberry to destroy the satellite.

When Jaden re-summons "Elemental Hero Neos" using "[[Hero Flash!! (anime)|Hero Flash!!]]", the spirit of Glow Neos remains at the satellite, while a separate spirit of regular Neos returns to the Duel. After Jaden activates "Neo Space" and Summons "Elemental Hero Neos" again, "Neos" rejoins Hassleberry. Sarina is able to stop the satellite from firing at Neos and Hassleberry, and this allows them to demolish it completely. Jaden defeats Sartorius with "[[Reverse of Neos (anime)|Reverse of Neos]]," and The Light of Destruction leaves the latter's body. Sartorius reveals that The Light of Destruction took his fortune-telling abilities with it when it exited his body. He therefore allows his tarot cards to blow away in the wind. After that, a KaibaCorphelicopter shows up, with Sarina aboard, alive and well.

Duel Academy is transported to [[Duel Monsters Spirit World|an alternate dimension]] where ''[[Duel Monsters]]'' can take physical form, and Jesse ultimately appears to sacrifice himself to grant the rest of the school passage back to their own world. Depressed at the loss of Jesse, and blaming himself for it Jaden willingly attempts to go back to the alternate dimension, taking a group of his insistent friends with him, though they end up in another, desperate dimension. However, Jaden's guilt for Jesse's situation soon leads to an obsession. He begins to think only of finding and saving Jesse and begins to disregard what his actions may make befall his other friends. Because of this, his friends [[Alexis Rhodes]], [[Tyranno Hassleberry]], Chazz and [[Atticus Rhodes]] all get captured and sacrificed by [[Brron, Mad King of Dark World (character)|Brron, Mad King of Dark World]] in order to create the "[[Super Polymerization (anime)|Super Polymerization]]" card. When Jaden finally wins against Brron, [[Syrus]], [[Axel Brodie]] and [[Jim Crocodile Cook]] arrive. Witnessing the others being sacrificed because of Jaden's obsession to rescue Jesse causes them to abandon him, leaving him alone.

Zane tries to Duel Jaden to snap him out of his guilty mindset and get him focused on stopping Yubel, but he only continues doubting himself more and feeling worse. Then Jesse reappears, though he is possessed by Yubel. Learning that his friend is being controlled, Jaden puts his problems aside for the time being so that he can save Jesse. However, when Jaden finally Duels Yubel to save Jesse, it is revealed that Yubel actually removed Jesse's soul from his body and placed him inside the "[[Rainbow Dark Dragon (anime)|Rainbow Dark Dragon]]" before taking over. Jaden manages to exorcise Yubel out of Jesse, but in one foul swoop, it snatches the "Super Polymerization" card from Jaden and then forces him into a Duel. Before the final clash, Jaden finds out that Yubel's power was previously augmented by the Light of Destruction while it was still stranded in space. Although he feels guilty because his actions led to Yubel's exposure, the sheer atrocity and shamelessness of its actions prevents Jaden from feeling any sympathy towards the deranged spirit.

====Darkness====

Jaden eventually regained his love for Dueling while teaming with Alexis in a Tag Duel. While Dueling alongside her, he also made amends with her and repaired their friendship, making him more open to his friends again.

Eventually, Jaden learns that the person that everyone thought was Fujiwara was actually the spirit of one of his cards, [[Honest (character)|Honest]], and that Fujiwara doesn't even appear to be on earth. Although Jaden doesn't know what Trueman's intentions are, he has found that the enigmatic dark entity pulls people into the world of Darkness. He realizes this too late, having been distracted by Trueman's actions in Domino City, thus giving the real Nightshroud, using Yusuke Fujiwara's body as a vessel, to attack the students at Duel Academy, only arriving in time to see Nightshroud possessed Fujiwara defeat the last student, [[Atticus Rhodes]]. Along the way, Jaden meets Jesse in Domino City, but mistakes him for Trueman after Sartorius infected his "[[Polymerization (anime)|Polymerization]]" card. After a Duel they fail to finish, Jaden realises it is Jesse and not Trueman he's Dueling and the two of them return to Duel Academy together. Both are then challenged to a triple Duel with Nightshroud, with only Jaden remaining the winner after he purges Nightshroud from Fujiwara. However, Jaden Duels the bodiless Nightshroud in a final Duel with the world at stake. The Duel was intense straight from the start; with Jaden Summoning "[[Neos Wiseman (anime)|Neos Wiseman]]" using "[[Yubel (anime)|Yubel]]." Jaden finally defeats Nightshroud by summoning "[[Elemental Hero Divine Neos (anime)|Elemental Hero Divine Neos]]" to defeat Nightshroud's "[[Darkness Neosphere (anime)|Darkness Neosphere]]."

After the graduation ceremony, Jaden decides to leave Duel Academy quietly; however, he is brought to the room that contains Yugi's Deck by Winged Kuriboh. Yugi appears there, and after the Winged Kuriboh card glows with a bright light, Jaden finds himself in [[Domino City]] in the past, bumping into a younger Yugi who still holds the [[Millennium Puzzle]]. He challenges his hero to a Duel, and as he shuffles the Deck he senses the presence of the [[Egyptian Gods]] in Yugi's Deck. The Duel then begins, with Yugi eventually Summoning "[[Dark Magician (anime)|Dark Magician]]" and Jaden Summoning "[[Elemental Hero Neos (anime)|Elemental Hero Neos]]", their ace monsters, which battle it out. After a long battle, [[Yami Yugi]] finally takes over Yugi's body and welcomes Jaden, and Summons "[[Slifer the Sky Dragon (anime)|Slifer the Sky Dragon]]". Jaden's face lights up, and he finally realizes Dueling really is fun. He then sends "Elemental Hero Neos" to attack "Slifer The Sky Dragon" and the Duel comes to an abrupt end with Jaden, Yami and Yugi all smiling. It then pans to Jaden in a desert. Jaden then turns around and looks at the sky, and thanks Yugi for reminding him that he has a long way to go, and Dueling is fun, and shouts his very last "Gotcha!" towards the sun. His bag rustles, and he opens it to find Pharaoh and Banner inside. Inside Pharaoh's collar he finds a letter from his friends each with their own message for him. After reading it, Jaden, Banner, Pharaoh, and presumably Yubel decide to travel together, and thus Jaden runs off towards the sunset, off to start a new adventure.

Jaden is known to have traveled to [[wikipedia:Venice|Venice]] in ''[[Yu-Gi-Oh! 3D Bonds Beyond Time]]'' before being attacked by [[Paradox]]. He is relentlessly attacked further by "[[Cyber End Dragon (anime)|Cyber End Dragon]]." "[[Rainbow Dragon (anime)|Rainbow Dragon]]" and "[[Stardust Dragon (anime)|Stardust Dragon]]" and despite the extra protection offered from Summoning "[[Elemental Hero Neos (anime)|Elemental Hero Neos]]," he was nearly overwhelmed by all their attacks. He only survives due to the intervention of [[Yusei Fudo]] and the [[Crimson Dragon]], the latter of which takes the final blows for him. He then explains to Yusei that he heard from his classmates about getting their cards stolen from Paradox and came down to Venice to stop him. They then use the Crimson Dragon to travel back to the days of [[Yugi Muto]], only to find they were too late to stop Paradox from killing Pegasus. They return thirty minutes earlier after recruiting Yugi to their cause, with Yubel scaring off the patrons just before Paradox would appear to Duel them.

Though only having one turn in the Duel, Jaden shows his mastery of fusion as he Summons a new Fusion Monster, "[[Elemental Hero Neos Knight (anime)|Elemental Hero Neos Knight]]," by fusing his "Neos" with Yusei's "[[Junk Gardna (anime)|Junk Gardna]]" and destroying Paradox's "[[Malefic Cyber End Dragon (anime)|Malefic Cyber End Dragon]]" and "[[Malefic Rainbow Dragon (anime)|Malefic Rainbow Dragon]]". He shows his characteristic excitement when seeing Yusei's [[Duel Runner]] during their first meeting and when Yusei [[Synchro Summon]]s "Junk Gardna" during his first turn. He and [[Yami Yugi]] also manage to convince Yusei not to forfeit after he loses faith in their victory after the Summoning of "[[Malefic Truth Dragon (anime)|Malefic Truth Dragon]]". He and Yami Yugi are able to give "Stardust Dragon" the power to defeat "Malefic Truth Dragon" and defeat Paradox. Following their victory, all the damage Paradox caused to the timeline is repaired and the three return to their respective timelines with Yusei promising to protect the future and meet him and Yugi again.

[[Yubel (character)|Yubel]] was the spirit of [[Yubel|a card]] Jaden owned in his youth.<ref name="ep131" /> Due to a promise made to [[The Supreme King|Jaden's past life]], Yubel protects him at any cost, putting several of his opponents into comas. Jaden's past life held romantic feelings for Yubel and pledged his love to her and her alone (all aspects of this are removed in the dub). She returns to seek out Jaden years later, wishing for him to make due on his past life's promise at any cost (in the dub, she wants revenge for being sent away). Every action she takes is to get closer to Jaden and believes that everything she does is out of love, no matter how heinous the action. Jaden eventually accepts her feelings and fuses himself with her via "[[Super Polymerization (anime)|Super Polymerization]]".<ref name="ep155">{{episode|Yu-Gi-Oh! GX|155|ref}}</ref>

In his second year, after his [[Yu-Gi-Oh! GX - Episode 059|second Duel]] with [[Aster Phoenix|Aster]], Jaden's Deck is left blank to his eyes due to [[Sartorius]]' powers. With the inability to use his old "Hero" Deck, Jaden received a new one that included the "[[Neo-Spacian]]s", cards he created as a child for a [[KaibaCorp]] contest. The highlight of Jaden's new Deck is "[[Elemental Hero Neos (anime)|Elemental Hero Neos]]", which can initiate [[Contact Fusion]] with the "Neo-Spacians" to summon Fusion Monsters without the need for "Polymerization". Jaden also includes support for the "Neo-Spacians" and "Neos", such as "[[Neo Space (anime)|Neo Space]]", to prevent the new fusions he Summons from returning to the [[Fusion Deck]] at the End Phase through their effects. He combines this Deck with his old one.
