From Marvel, Esad Ribic's different time period Thor designs:
Young Thor
Jason Aaron:
Modern Thor
Jason Aaron:
Future King Thor!
Jason Aaron on King Thor:
Young Thor
Jason Aaron:
Jarnbjorn is the name of young Thor's axe, which in Norse means Iron Bear. That axe made its first appearance in THOR: GOD OF THUNDER #1, but you can expect it to pop up elsewhere in the [Marvel Universe] as well.
That face says it all, doesn't it? That is one cocky young godwith a very large axe. Looks like the kind of brash, mead-swilling, combat-loving god who might get himself into lots and lots of trouble. In fact, I'd count on it
Modern Thor
Jason Aaron:
Sleeves or no sleeves? Count me in the sleeveless camp. We'll see Thor sporting both looks in the new series, but for my money, any dude who carries a giant hammer for a living shouldn't be afraid to show off his arms.I prefer the sleeveless look, but the big guy can still armor up if need be.
We may see Thor's helmet design change from time to time, depending on the battle. This one is probably my favorite though. It looks like a helmet you could take off in a pinch and use to beat a troll to death
Future King Thor!
Jason Aaron on King Thor:
Meet the Thor from the end of time. With the eye patch and the long white beard, King Thor looks a bit like his dad, Odin. He even wields his father's sword. But he's a very different sort of All-Father, in a far different time.
This [Thors left arm] isn't armor. King Thor lost an arm somewhere along the way, so when he goes into battle, he wears an arm of the Destroyer
