Mjolnir

Mjolnir is a legendary Uru warhammer and the primary weapon of Thor. 

Capabilities

• Weather Control: The hammer can control the basic elements of a storm. It can create full on storms complete with thunder, lightning, hurricane-force winds, and torrential rains at a moment's notice. Thor can manipulate the elements to his will, such as spinning the hammer around, which releases powerful winds, or by channeling lightning through his body. The hammer can generate lighting, and can manipulate and absorb energy.
• Worthiness Enchantment: The hammer has enchantment to allow only Thor to lift and control the hammer and access its full potential. Apparently, the connection between Thor and Mjonir can be severed both willingly and in the case that Thor dies.
• Teleportation: The hammer allows Thor to teleport himself to different places in the universe almost instantaneously. With the help from Heimdall and the Bifrost.
• Flight: Thor is capable of hurling Mjolnir with great force and, by holding onto the leather strap, is capable of flying through the air at tremendous speeds and is able to perform several aerodynamic feats and change his own course through the power of thought. He can also hover in air by only constantly spinning the hammer through the strap. Thor has been seen flying and hovering in the air without Mjolnir though. 
• Armor Manifestation: Thor can also transport his Asgardian Battle Armor to himself and "armor up" at any time in case he removes the armor or it undergoes battle damage. His armaments includes: his chestplate, the chain-mail sheathing on his arms, the leather wrist cuff(s), his helmet, and his cape.
• Healing: As as stated in Norse Mythology, Mjolnir is capable of healing injuries, illness, disorders, infections, intoxication etc..., by using its magical powers. Thor can even use this ability on himself.
