Hell Dolphin (じごくのイルカ, Jigoku no Iruka) is a character from the manga Bobobo-bo Bo-bobo. He is a District Leader from the Hair Kingdom.
Hell Dolphin is leader of the 6th District of the Hair Kingdom, his identity originally remained hidden because the general was going to be the winner of a Jump contest where the readers can create the villain.
When he is finally revealed, the general turns out to be a strange walking rubbery dolphin tea-pot/coffee-pot! While fighting Bo-bobo, Hell Dolphin keeps going on about being the winner of this contest while easily being beat up. He gets thrashed around by Torpedo Girl and the Hajike trio bombard him with many odd hajikelist attacks. In the end, Hell Dolphin is defeated when several other fan-created characters appear from an alternate dimension, taking their revenge for his victory by dragging him back to their world!
His main style is "Peropero Shinken" (ペロペロ真拳; "Fist of Beep-Beep"), allowing him to release tracking radar such as a dolphin does.
