* Yusaku is the first main protagonist since [[Jaden Yuki|Jaden]]:
** To use [[Field Spell Card]]s in his Deck.
** To not have his father be central to the plot of his series.
* Yusaku is the first main protagonist since [[Yusei Fudo|Yusei]] to use [[Normal Monster]]s in his Deck.* Yusaku has is the following distinctions from the other only main protagonistsprotagonist:** He is the only one who Who has never had a Duel end with no result.** He is the only one who Who has never lost a Duel to another human.** He is the only one to To have neither of his parents, or any family, seen or mentioned at any point.** He is the only one who Who never participated in a tournament or [[Tag-Team Duel]] (unless Yusaku fighting Bit and Boot, 2 Duelists in 1 body, counts in the case of the latter).** He is the only one who Who is not a close friend of his series' [[Skye Zaizen|female lead]], although he does occasionally work with her.** In the English dub, he is the only one to not voice the "previously" banner at the start of some episodes, as that role is given to Ai instead.
* Yusaku has several similarities to Yusei, despite having a much harsher demeanor than the latter.
** Both have "Fu" as the first part of their surnames.
** Both have only lost Duels in flashbacks that take place prior to the beginning of their series.
** Both have never been turned evil at any point in their series like the other main protagonists, though [[Yuma Tsukumo|Yuma]] never actually turned evil as Astral embraced evil power and merged with him into Dark ZEXAL.
** Both are the only main protagonists to not use the Spell Card "[[Monster Reborn (anime)|Monster Reborn]]".** Both Yusaku and Yusei also both have similar monsters in their Decks.
*** Dragon-themed primary ace monsters with 2500 ATK and defensive effects that focus on protecting other cards ("Firewall Dragon" and "[[Stardust Dragon (anime)|Stardust Dragon]]").
* Much like [[Sherry LeBlanc]], Yusaku has 1 or 2 people they can actually trust (in Yusaku's case, he only had Kolter). Also, both of them had a desire for vengeance against the organization that took the lives of someone important to them, despite having different backgrounds (Yusaku against The Knights of Hanoi and Sherry against [[Iliaster]]).
* Yusaku is the first character to use five different Summoning methods ([[Link Summon|Link]], Ritual, [[Fusion Summon|Fusion]], [[Synchro Summon|Synchro]], and [[Xyz Summon|Xyz]]).
** All three have used cards that can be seen with deep meaning behind them and were key in their victory. For Yusaku, it was "Recoded Alive" which was also used to defeat Varis in both of their Master Duels. Of the three, Yusaku's is the only one to be a Trap instead of a Spell.
** Also unlike Yugi and Yuma, Yusaku used a [[Borreload Furious Dragon (anime)|card]] that was not his for his final Duel. Although his was given to him, rather than offered.
* Each of Yusaku's non-Link ace monsters bear differences monsterss has at least one difference from each the other.three:** "Cyberse Magician": The only one to not be a Dragon-themed Extra Deck monster, instead being a Spellcaster-themed Main Deck monster.** "Cyberse Clock Dragon": The only one to require a [[Clock Wyvern (anime)|specific monster]] in its Summon mechanic, and to have an effect that activates upon its Summoning.** "Cyberse Quantum Dragon": The only one to not have an effect that increases its ATK.** "Firewall eXceed Dragon": The only one to not be a Level 7 monster with the word "Cyberse" in its name, instead being a Rank 4 monster with the word "Firewall" in its name, and to not have an effect that protects other monsters from attacks or card effects while a Link Monster is on the field.
