Boomerang Character!
Hey, it's Mel. I've got this thunder god again, because Norse, damnit.
After regaining Mjolnir, he went to Asgard and played with his hammer pondered things like implanting memories and curtailing powers and other things Odin did. And hit Frost Giants and other brigands on Asgards borders.
He's back on Midgard, and has slid closer to god than the mortal memories he still has lurking in his brain.
