Jarnbjorn was the Dwarven forged battle axe wielded by Thor. Thor used this axe long before obtaining Mjolnir.[1]


Jarnbjorn the battle axe

During the 11th Century, Thor faced off with the Celestial-powered being called Apocalypse. Seeking revenge, Thor blessed Jarnbjorn with his own blood to embue it with the power to pierce Celestial armor. Eventually Thor lost Jarnbjorn. Kang the Conqueror recovered Jarnbjorn from Baron Mordo's tomb in Brazil.[2]

The axe was then stolen from Kang by the Apocalypse Twins during their training under him. Uriel and Eimin used the weapon to kill Celestial Gardener outside the Starcore space station and become the new Apocalypse[3]. This was part of an elaborate plot concocted by the twins to frame Earth for the death of the Celestial Gardener so the Celestial Exitar would destroy it.[4] Then the Twins convinced Scarlet Witch to case a spell that transported every Mutant on Earth to their ark so mutantkind would be survive and humankind would be destroyed along with Earth.[5].

In a divergent universe, their plan would've succeeded, but from the said universe, the remaining Avengers Unity Division arrived and thwarted the Twin's plans.[6] Thor reclaims Jarnbjorn and uses it to kill Exitar by striking him in the neck.[7]


It's unknown what Thor does with Jarnbjorn after, but he is seen holding Jarnbjorn on the cover of Avengers Vol 5 #35, likely using it as a replacement for Mjolnir, which he lost the ability to wield.[8]


  • "Jarnbjorn" means "Iron Bear" and is written as you would say it in a Norwegian dialect.
