WARNING: The following article contains spoilers for Marvel's Thor: Ragnarok, and potential spoilers for Avengers: Infinity War, arriving in theaters May 28.
If you were to ask casual fans to pick their favorite weapon in the Marvel Cinematic Universe, Thor's enchanted hammer Mjolnir would undoubtedly land near the top of the list. Of course, that just makes its destruction in Thor: Ragnarok all the more devastating.
The God of Thunder didn't let the loss of his trusty hammer slow him down, however, as he was still able to defeat the Goddess of Death Hela, and save his Asgardian brothers and sisters. The next time we see Thor will be in this summer's Avengers: Infinity War, where it will be an all-hands-on-deck situation as Earth's Mightiest Heroes and the Guardians of the Galaxy must work together to stop Thanos from collecting the Infinity Stones.
To stand up to a villain like the Mad Titan, of course, will require every weapon in our heroes' arsenal, to which Thor is currently down his primary asset. Luckily, that may be about to change, after a photo surfaced on an Infinity War Funko Pop! figure of Thor brandishing an ax that may very well be the Marvel Cinematic Universe version of Jarnbjorn, the weapon he wielded before he gained Mjolnir. Although Infinity War concept art that surfaced in February hinted at Jarnbjorn's MCU debut, the leaked Funko Pop! figure seems to confirm it is indeed on the way.
Now, many of you may be wondering, what the heck is a Jarnbjorn? Don't worry, because you came to the right place. Here you'll find everything you need to know about Thor's mighty ax before it makes its grand Marvel Cinematic Universe debut.
Jarnbjorn, Young Viking Thor's Battle Ax
For those not familiar with Thor's comic book history with Mjolnir, here's a quick summary: The hammer used to belong to his father, Odin, and was set aside until Thor proved himself worthy to lift the powerful weapon. The majority of Thor's adventures in the Marvel Comics Universe always showed him with Mjolnir, until 2013's Thor: God of Thunder -- from writer Jason Aaron and artist Esad Ribic -- came onto the scene. The first issue of the series introduced what is known as Young Viking Thor, nicknamed for the fact that the young Odinson spent much of his time partying and fighting alongside Earth vikings around the time of 800 A.D. It was here that we got our first glimpse of Jarnbjorn, as Thor came to the defense of his drinking buddies.
When it comes to choosing weapons, if a big, mythical hammer is off the table, an even bigger ax is obviously the next best option. Much of Aaron and Ribic's run on Thor: God of Thunder included flashbacks to Young Viking Thor and Jarnbjorn. The ax even played a crucial role in another Marvel Comics series, Uncanny Avengers.
