Majin Tensei came out for the Super Famicom in Japan in 1994, a strategy RPG played on maps with a team of humans and demons. 101Leafy researched the game and lists its 144 demons here with their stats. The names use the official English spelling from other games in the series where there is one, and 101Leafy's translation for the rest.
Story
Nationalist wars spread across the world through the 1990s, and the ceasefire only came after missile strikes on cities. By 202X central Tokyo has been rebuilt as NEO TOKYO, but the bombed waterfront district NIEDER TOKYO D-03 was left out of the plan and given up ten years ago. Earthquakes keep shaking NEO TOKYO, and people say demons have been seen in the streets. The Hero, born in D-03, is looking into the rumours through a computer network when a stranger sends him a message and a program, and he has to decide for himself whether to use it.
