History
The Arcane Warhead was constructed by Doctor Octopus of the Superior Avengers in the Negative Zone for their true purpose on Earth-616: return to their time and kill Annihilus so they could rule it. The Warhead required a massive amount of magical energy to charge, which the Superior Avengers did by stealing various magical artifacts and transmitting their energy through Doctor Octopus' Tentacles. She could also siphon the energy from living magical users, but could only store it for a short time before needing to deposit it.[1] They ended up getting all energy they ever needed at once when they fought the real Avengers, and Scarlet Witch hit Doc Ock with a mystic blast.[2]
Their plan was forced to accelerate, and Superior Avengers prepared to transport the Arcane Warhead back to their time through a Time Platform, only for Annihilus to reveal that he had been possessing the Abomination this entire time and destroy it.[3]
