Heroic

"Heroic" is an upcoming archetype used by Gauche in the Yu-Gi-Oh! ZEXAL series. It seems to involve Warrior-Type monsters with effects that allow them to double their original ATKs. Their team symbol is a crimson butterfly and they seem to be based on various famous warriors and weapons, such as Spartacus and Excalibur.

So far, all "Heroic Challenger" monster are EARTH-Attribute, and "Heroic Champions" are LIGHT-Attribute.

In the anime, "Heroic" itself is not an archetype, but "Heroic Challenger" and "Heroic Champion" are. The inverse is true in the OCG.
