Amon is widely considered one of Hell's most formidable demons, best known for his devastating campaigns on Earth and his notorious relationship with Sirene. When he attempted to possess a human named Akira, the fusion went catastrophically wrong—instead of a takeover, it created Devilman, a being that would become central to demonkind's fate. The incident marked a turning point in the Demon Realm, and his name became synonymous with both raw power and spectacular failure among demons.
