Stormbreaker

Stormbreaker is a fictional weapon that appears in Marvel Comics, primarily associated with Thor. It is depicted as a powerful mystical axe, forged from the metal of a dwarf star and enchanted by Odin. Initially, Stormbreaker was the weapon of Beta Ray Bill, an alien from the planet Korbin, who proved himself worthy of wielding Mjolnir, Thor's hammer. As a reward for his valor, Odin had the dwarves of Nidavellir forge Stormbreaker for Bill, making it an equally potent weapon.

Stormbreaker grants its wielder superhuman strength, durability, and the ability to control the weather, summon lightning, and fly. It can also be used as a projectile weapon, capable of returning to the wielder's hand, and can open portals to other dimensions. The axe is exceptionally durable and can withstand immense force. While Beta Ray Bill is its primary wielder, the weapon's power is tied to the worthiness of its user, similar to Mjolnir.

The weapon has featured in various comic book storylines and has been adapted into other media, including the Marvel Cinematic Universe (MCU). In the MCU, Stormbreaker is forged by the dwarves of Nidavellir for Thor in Avengers: Infinity War, intended to be a weapon powerful enough to defeat Thanos. Its appearance and capabilities in the MCU are largely consistent with its comic book origins, emphasizing its immense power and connection to Thor's destiny.
