Kiss was never really my kind of band, I was a little too young. Death was more my style. The band Death that gave us the whole genre of death metal. RIP Chuck Schuldiner. Death did a cover of a Kiss song, back in the day. It was called God of Thunder and it's a pretty kickass song. Chuck does this amazing deathy growl of the chorus where he goes "God of thunder! . . . and rock and ro-o-oll."
Oh man when that song first came out did I wish that rock and roll part wasn't in it. It just cheesed up the whole song. Well, actually the song is so awesome that it was able to withstand the cheesy onslaught. But come on, as if Thor needs more in his portfolio than just thunder. Because what's more awesome than a thunder god?
The Marvel Now series Thor: God of Thunder says the answer to that question is nothing! Well, maybe one thing. We'll get to that in a second.

As someone who happily professes a love for death metal, maybe it comes as no surprise that I've been a fan of Thor all my life. That most Frazetta-ish of Marvel superheroes was also one of the most versatile, since he could be hanging out in Asgard with his fellow immortal Norse gods battling trolls and frost giants, and then he could hop over the Rainbow Bridge to Midgard* to fight Kang the Conqueror alongside Iron Man and Captain America. Then the next issue he would gladly take to space to aid Beta Ray Bill in stopping Galactus from devouring the planet Poppup.
Jason Aaron prefers to play a more god-like, heroic fantasy take on Thor, and Esad Ribic is the perfect artist for his interpretation. We are treated to no less than three different Thorian eras, or Ages of Thunder if you will. We get a young, brash Thor who relishes leading vikings into bloody battle. Current Marvel Universe Thor off gallivanting in space, and a far-future Thor who looks an awful lot like his dear old dad Odin. Not necessarily a good thing.
In each of these timelines Thor faces the menace of something known as the god butcher. A monster that goes around butchering gods of various pantheons. Thor, being a god from some pantheon or other, is square in the god butcher's sights. Not that Thor has any intention of being butchered, but he might not have much say in the matter. Because this guy butchers gods. That's what he does.
Having established that in the first two issues, I'm now curious to know why. I can dig it, and accept him as a worthy foe for Thor, I just hope there's an intriguing origin or motive for ole GB. We get a hint of the anger and contempt he feels for gods in this sequence:

SO bring it home for us, Mr. Aaron! What's more awesome than a thunder god? A god butcher, apparently. But I say thee nay! Thor shall prevail. What's a god without someone to have faith in him?

*Midgard means Earth, as if I needed to tell you that, true believer!
