Hell Biker in Persona O.A.
Despite the portrait remaining mostly unchanged (with minor revision of coloring), Hell Biker's 3D model has him wear a helmet in addition since Shin Megami Tensei III: Nocturne. This inconsistency is readily apparent in Persona 3 and Persona 4 where both the artwork and 3D model are used in-game. Persona 5 and Shin Megami Tensei: Liberation Dx2, however, feature him sans helmet.
