WARNING: The following article contains major spoilers for Thor #2, by Jason Aaron, Mike Del Mundo and Joe Sabino, on sale now.
Since reclaiming his title as the Marvel Universe's resident God of Thunder, Thor Odinson has decided to enlist some dwarves to build him a whole assortment of hammers. With Mjolnir lost to the heart of the sun, he's had to make due with an eclectic variety of new weapons, many of which we saw in last month's debut issue in a very Iron Man 3 fashion.
Fortunately, there are still plenty of hammers for our hero to use, and this month's Thor #2 introduces not one, but three new ones to his arsenal.
The previous issue ended with Thor and his brother Loki traveling to Hel, where the two brothers quickly foundnd themselves having a family reunion with Baldur and Tyr, plus Skurge the Executioner and Karnilla, Queen of the Norns. During a fight with the Firepedes of Muspelheim led by the Sindr Queen, Thor's gold hammer that he brought along winds up getting melted by the burning Muspel blood. He summons a spare hammer, which hits Loki in the face (naturally) before it splits into two hammers for him to beat the beasts down with.
The star of the show, however, comes near the end of the issue. Tyr and Karnilla inform the group of a singing demonic train carrying valuable cargo: a brand new weapon that Sindr plans to use on her enemies. Though exactly what the weapon is isn't clear, the Asgardians know that they need to take it from her and use it against her army. Riding in their respective battle truck and motorcycle, Baldur and Karnilla distract the Fire Goblins on board the train so they don't what Thor did for his part of the plan. Though he himself is watching from the safety of the boat alongside Loki and their pets, he left a little present in the middle of the track. As he puts it, different missions require different hammers, and this is one such occasion.
But this isn't just any hammer, it's a Bomb Hammer. And true to its name, the hammer detonates to impressive effect, destroying the track and sending the locomotive hurtling into the river below.
Though the Bomb Hammer does its job, it also leads to an unintended consequence. As the issue ends, we learn the "valuable weapon" that's now been unleashed isn't a thing, it's a person. Specifically (as we'd previously theorized) Hela, Goddess of Death and her giant wolf Fenris, and they're working with Tyr to reclaim Hel and have Thor trapped in Fenris' powerful jaws.
With Hela and her pet now added to Thor's list of troubles, he's going to need an even stronger hammer to take down his niece and her dog.
