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. 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.
