Once I was Simon Waterson, a college football star who was transformed into a frog by a slighted witch. Then I picked up a sliver of Mjolnir, and was granted the power of Thor.
Now I am Throg, the Frog of Thunder. Evildoers beware.
I learned about Throg a few years ago, and it was (and remains) one of the funniest concepts I've ever heard; it's completely bananas, I cannot get enough of it.
And yes, I call my dupehammer Frogjolnir (the real in-universe name of Throg's mini-Mjolnir, because there is a god and he works at Marvel Comics).
