"
Evil HERO" (
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".
They were released in
Gladiator's Assault, but were mainly featured in
Duelist Pack: Jaden Yuki 3. The only "Evil HERO" monsters to not have a separate counterpart are "
Evil HERO Infernal Gainer" and "
Evil HERO Infernal Prodigy".
Prior to the
Problem-Solving Card Text rename to distinguish between cards in the "
HERO" archetype and cards that simply include "Hero" in their name, cards that support the "HERO" archetype in the
OCG instead supported "Elemental Hero", "Destiny Hero" and "Evil Hero" as a group in the
TCG ("Masked HERO" and "Vision HERO" had not been released in the
TCG at that time). This is the only time "Evil HERO" has been treated as an archetype.
