He no longer needs them, but in the past Thor has employed a belt of strength, gloves for holding Mjolnir, and a special armor when his bones were brittle due to a curse.
The warhammer Mjolnir. Thor wields Mjolnir, a hammer forged from uru metal. Mjolnir is virtually unbreakable, and allows Thor to command the powers of the storm, causing rain, thunder and lightning. Thor can channel the storm�s fury into devastating blasts of energy that can destroy even Secondary Adamantium. He can also channel his godly energies through Mjolnir into blasts so powerful that they can slay even immortals. Mjolnir can absorb other energies into itself, which Thor can then release.
Mjolnir obeys Thor�s commands as though it were alive, and if Thor�s will is strong enough, the hammer can pass through nearly any barrier to reach him should he so desire. Using this command over Mjolnir�s flight path, Thor is able to use the hammer to fly, achieving escape velocities. Mjolnir can also transform Thor into his civilian guises. When Thor is a civilian, the hammer most often becomes an old wooden cane. While employing a mortal guise, Thor will transform back into his mortal form should he be separated from Mjolnir for more than 60 seconds.
By spinning Mjolnir in a circle, Thor can open portals to other dimensions. Formerly, it also allowed him to travel in time, but Immortus removed this power. Enchantments surrounding Mjolnir prevent it from being wielded by anyone save those who have been found worthy. Thus far, this includes Thor, Odin, Tiwaz, Red Norvell, Beta Ray Bill, Superman (JLA/Avenger series), Wonder Woman,and Captain America. To anyone else, Mjolnir cannot be lifted from the ground nor wrested from Thor�s grip.
