Billy Kaplan, an electrokinetic mutant with magical and reality warping abilities, joined the Young Avengers under the name Asgardian (which was later changed to Wiccan) as part of Vision's fail safe program to ensure the existence of the Avengers team. Wiccan and his teammate Speed are believed to be the reincarnations of the Scarlet Witch's dead twin sons. He is considered a powerful mage, and was revealed to be the Demiurge, a being of great power, destined to one day "rewrite the laws of magic".
