As such, when he finds himself cornered (for example when "Odd-Eyes Pendulum Dragon" was destroyed in his Duel against Sora Perse), or something happens that breaks his confidence (like when Declan and Sylvio used Pendulum Summoning), he tends to pull his goggles down so nobody can see his eyes.
At times like these, he ends up recalling lessons from his father, or relies on support from his friends or his mother to regain his confidence and continue the Duel.
Initially, Yuya was more emotionally vulnerable regarding Pendulum Summoning, believing it to be a power granted only to him.
When both Declan and Sylvio Pendulum Summoned, he was speechless, but coaching from Skip and the lessons he learned during his Qualification Duels have turned him into a Duelist that enjoys the challenge set before him, and he smiled as he was cornered by Sylvio when he Pendulum Summoned in their rematch.
Yuya has a habit of putting his goggles over his eyes when he is either upset or embarrassed, something he did since he was young.
When Yuya Duels, he announces "Ladies and gentlemen! In the dub, his catch phrase is "Swing into action".
Yuya is a young teenage boy with crimson eyes, and dual-colored green and crimson hair of average length sticking out in downwards pointing spikes all around his head in a similar manner to Jaden Yuki, with the exception of one short upwards pointing spike of green hair.
