Neo Dio (rendered as NEOネオ DIOディオ) is reoccurring antagonist and boss character in the World Heroes series.


Because of the failure of his previous creation, Geegus, Damned created a new, stronger, better artificial soldier: Dio. But Dio developed his own consciousness and now roams different eras, killing many people.

After his defeat in the second game he uses Damned's technology to improve himself, returning later to exact revenge for his defeat. He kills Zeus during his confrontation with the World Heroes and challenges them to a fight, once again ends defeated.


Neo Dio is a highly destructive maniac that hates peace. He believes himself to be the ultimate lifeform and thus invincible.
