"Heroic Champion" (H-CHiroikku Chanpion, written as H-C in the anime) is an archetype of WarriorXyz Monsters, which are part of the "Heroic" archetype, that are used by Nistro in the Yu-Gi-Oh! ZEXAL anime. Its support cards were retooled into a "Heroic" support when released in the OCG/TCG.
All of the "Heroic Champion" monsters are based on mythological weapons and require Level 4 Warrior monsters to be Summoned.
