Genma bestiary: confirmed origin and named foes

Director Satoru Nihei says Genma dwell in the depths of hell and enter the human realm through portals when Malice overflows. The Oni guard the gateways and destroy Genma that try to cross.

Capcom calls Shuten Doji a colossal Genma who has taken Mount Oe as his stronghold. The announcement questions whether his claim to be the legendary Oni is true; this page does not resolve that story question.

The reviewed sources do not provide a full Genma roster, weaknesses, attacks, drops, respawn rules or retail encounter order. A trailer name or visual is not enough for a strategy; those fields need current gameplay evidence with platform, build and date.
