Gargant first appeared in Onimusha: Blade Warriors. Gargant was an Oni-turned traitor who became Nobunaga Oda's right-hand man and the mightiest Genma warrior alive. He also had a close relationship and a mutual respect for another great demon warrior, the famous swordsman, Gogandantess.
Gargant was a traitorous Oni who betrayed his clan and swore his allegiance to the nefarious Demon Lord Fortinbras. After the demise of Fortinbras, he had yielded his position as the righthand man under the new Genma Lord Nobunaga.

Onimusha 3: Demon SiegeEdit
Shortly before Onimusha 3: Demon Siege takes place, Gargant was traveling with a massive Genma army preparing to meet Nobunaga. Samanosuke sought Gargant to avenge Kaede's death, and managed to destroy his entire army before confronting Gargant and killing him.
