Hell Biker is one of the 5 Fiends that can be fought in the game found in specific spots in the game, being one of the hardest and rarest random encounters in game (along with the other Fiends). After defeating him, he drops one of the 5 best weapons in the game.
"A biker-turned-Fiend that claims to come from hell. With all the hatred of himself and the world, his reliance of only his own power turned him into this abominable figure."
—Shin Megami Tensei III: Nocturne compendium
After defeating Daisoujou, Hell Biker will appear on the freeway between Ikebukuro and Kabukicho. Upon arrival in the Fiends' realm, Hell Biker appears, demanding the Demi-fiend's Candelabrum. He mostly talks with a punk attitude. After he is defeated, he leaves behind the Candelabrum of Dignity.
Hell Biker can be encountered by using an Ultimate Summon Orb in front of the boss room in Shibuya's Celu Tower bronze-level instance. His plug-in can be acquired by turning in Essences of Yetzirah to the researcher in the Shinjuku Babel cathedral. He is a special triple fusion of Matador, Alice and Girimehkala.
"A motorcyclist whose violent nature turned him into a demon. His anger with himself and the world causes him to lash out, that everyone else would suffer as well."
—Persona 5 background
Hell Biker is the fifth Persona of the Death Arcana and can only be obtained through fusion in the Velvet Room. He is one of the four Personas that learns the Speed Master skill and the second Persona to learn Fire Boost. He is also one of the three sources of the Trigger Happy skill. Hell Biker is the first Persona to learn Mamudoon. When itemized through Electric Chair execution, Hell Biker yields the Black Jacket armor for male characters, which has 120 DEF, 12 EVA and protects the wearer from Curse insta-kill skills.
"Clothed all in black, a red scarf streaming, he rides full of rage calling himself the "Angel of Hell". His strong hate for the world and himself turned him into this vile demon whose violent hatred is infectious."
—Shin Megami Tensei Liberation Dx2 compendium
Hell Biker is an uncommon Rank 4 demon which can only be obtained through summoning. His unique skill "Red Zone" which imparts Critical status on all party members, is limited to 3 uses per battle.
Jeng Yun Tsai dressed up as Hell Biker during the Liberator's party for the Hee-lloween Party-ho! event. He also encountered a young man who was transformed into one in the "Road Rage" event.
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, however, features him sans helmet.
