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 became the new Apocalypse.[3] This murder 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] The Twins then convinced Scarlet Witch to cast 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 Divions arrived and thwarted the Twins' plans.[6] Thor reclaimed Jarnbjorn and used it to kill Exitar by striking him in the neck.[7]

For a time, Jarnbjorn wasn't seen, but after was eventually ysed as a replacement for Mjolnir, which Thor lost his worthiness and therefore the ability to wield after his battle on the Moon against Nick Fury.[8]


Jarnbjorn has an enchantment placed on it that allows it to piece the armor of Celestials or armor created using Celestial technology.[2] Jarnbjorn has a charm that makes it indestructible, can be used to defend yourself from any attack, even large bursts of power, such as the beam of optical power of Apocalypse. Jarnbjorn is also a dangerous sharp blade, which can virtually cut and pierce anything, even structures so durable as the Celestial Armor.[2]
