During the War of the Realms, the hammer arsenal of Thor runs out, with him using the last one to battle Malekith who bonded to the Venom symbiote and recreated All-Black the Necrosword. While battling, Malekith took the hammer and through the symbiote transformed it into the Black Hammer of the Accursed, later defeated by Thor with the reforged Mjolnir.^[1][2]
