"Evil HERO" (Ｅ－ＨＥＲＯ（イービルヒーロー） Ībiru Hīrō) is a series of Fiend monsters with various Attributes (primarily EARTH and FIRE) that are part of the "HERO" archetype used by Jaden Yuki in the Yu-Gi-Oh! GX anime temporarily after being possessed by The Supreme King. They are corrupted versions of Jaden's "Elemental HERO" monsters. Most of the "Evil HERO" monsters are Fusion Summoned by fusing existing "Elemental HERO" monsters with "Dark Fusion" instead of the traditional "Polymerization".
