loki (all-butcher) (marvel)

Following the Multiverse's restoration, this variant of Loki was somehow transported back to his reality and imprisoned in a pit of Muspelheim vipers by Thor. Loki escaped by eating the molten serpents, setting his sights on All-Black the Necrosword, which had bonded with Ego after killing its prior owner, Galactus. Loki, disguised as a worm, fought the Living Planet for control of the weapon, where he eventually triumphed by whispering madness into Ego's ear for over a century. Bonding with the primordial symbiote and renaming himself Loki the All-Butcher, he slaughtered Ego to test his newfound strength before setting out to kill Thor and destroy all.
