Extremely durable weapon forged from the Asgardian metal Uru by the command of Odin; favored weapon of Thor. Only those of sound moral character and integrity may lift Mjolnir although it is possible to lift the Mjolnir without having moral character and integrity proven by the Hulk, it is unsure what allowed him to lift it. It may be his limitless capacity for strength which allowed Hulk to break such a powerful enchantment. The hammer can summon the elements wind, rain, thunder, and lightning for the wielder to use at their discretion. It is able to open interdimensional portals, such as the one to Asgard. Mjolnir possessed the power to bestow the ability of time travel to its wielder until Immortus removed it.
