Thor: Ranking Every Hammer Worst To Best
11. Earth-1610 Ultimate Hammer
Marvel Comics' Ultimate Universe, otherwise known as Earth-1610, has 'ultimate' versions of all its superheroes, including Thor. As you might suspect, Ultimate Thor has an Ultimate version of Mjolnir, and it's a pretty serious weapon, but with some tweaks to the hammer's lore.
In the Ultimate Universe, Mjolnir was created by Odin instead of the dwarves. It was crafted with a piece of Asgard embedded within, which gave it a specific purpose. The main purpose of the hammer was to help Asgardian be reborn following Ragnarok, and the piece of Asgard was the main component of accomplishing that feat.
This version of Mjolnir doesn't come with a worthiness clause either, and anyone who can pick up a hammer can pick it up. When this happens, it imparts the power of Thor onto its wielder, and it didn't sacrifice anything in granting those abilities to whoever held it.
Other than that, it's huge, looks really cool with both a hammerhead and an axe, has a super-long handle, and tends to spark blue electricity when it's feeling especially deadly. It's an incredibly powerful weapon, but it's not the most powerful version of Mjolnir in the Marvel Multiverse.
