Denjin Makai, roughly translated as "Hell Power God," is a Japan-exclusive brawler from Banpresto about fighting a futuristic gang that has allied itself with demons. It's notable for its huge character roster, unique energy-based specials, and team-up attacks.
Denjin Makai was released on the Super Famicom under the title Ghost Chaser Densei. Only Makai, Iyo, and Belva are playable and a stage was removed, but besides that it's a faithful port.
Denjin Makai and its sequel Guardians are the only brawlers that have special attacks that are executed by holding the attack button, inputting a command, and then letting go.
Denjin Makai is my jam. Its personality and presentation will grab you from the beginning and the innovative, deep, satisfying combat will have you coming back for more. Its soundtrack is full of energy and style, and the huge cast of fighters guarantee replayability. Its only downside is that it's too easy.
