Hyde emerges as a stoic and fiercely loyal member of the Five Gattles, an elite unit commanded by Jendle in *Duel Masters King!*. His unwavering allegiance traces back to a childhood trauma. Once celebrated among society's "Elites" for flawless academic and extracurricular achievements, Hyde's identity crumbled after a pivotal duel defeat—strongly implied against Abaku Onifuda—that exposed his imperfection. Public scorn drove him to a suicide attempt by leaping from a building, halted by Jendle, who offered redemption through the Gattles.

In *King!*, Hyde wields multi-civilization decks. Initially, his Water/Fire/Nature strategy centers on "Electrofused" Dispectors. After episodes 33-34, he shifts to Water/Darkness/Nature with "Suttered" Dispectors. His season record stands at 4 wins and 4 losses across 8 duels: victories include Bolts (Episode 8) and an unnamed duelist (Episode 31); defeats come from Joe Kirifuda (Episodes 26 and 41), Jendle (Episode 40), and another unspecified opponent (Episodes 33-34).

Reappearing in *Duel Masters King MAX*, Hyde allies with Abaku Onifuda at Ourai Academy ruins, operating alongside Himiko. His deck shifts to Water civilization featuring the Demonio race. His record declines to 1 win and 3 losses over 4 matches: a loss to Abaku (Episode 4), a win against Katta Kirifuda (Episodes 7-8), a loss to Joe Kirifuda (Episode 12), and a final defeat by Kira (Episode 14).

A key *King MAX* storyline explores Hyde’s history with Abaku, spotlighted in Episode 4 ("Abaku and Hyde’s Connection! Now, the Truth of the Rise of Kings Academy Will Be Revealed!"), which delves into their shared Ourai Academy past without detailing specifics. Hyde’s arc culminates in Episode 14 ("Rush in with the Power of Bonds! The Great Battle of Rise of Kings Academy!"), where Kira defeats him during the academy’s climactic battle.
