Thor summoned the Bifrost and joined Fortnite last August. Use Stormbreaker as a pickaxe, or demolish your opponents. You can also call your hammer, Mjolnir (which I can never pronounce), and destroy everyone around you.
Thor is one of the more popular characters, but maybe my least favorite design of the O.G. Avengers. Seriously, why have people totally abandoned Thor's helmet? Other than his hammer, it was his most iconic thing about him. Just a nitpick.
