So I'm starting a new campaign; a U.S. federal team of superheroes called The Fifty, featuring one hero from each state.

First up is Yellowhammer, the representative from Alabama. He gains immense strength, speed, stamina, and durability through the magical hammer he wields. The hammer also speaks to him, but refuses to communicate with or grant any of its power to any other human.

Alabama is unofficially called the "Yellowhammer state". It's called that because of a bird called the Yellowhammer, but I thought it sounded like a cool superhero name.

Arctic Fox is the representative from Alaska. She is able to grow steel claws from her hands and has heightened senses.

I'm liking the The Fifty can't wait to see more and think of what would happen if they met my United States Alliance 100 people fighting all at once.

Little Rock is a young stone-skinned boy from Arkansas.

That is a cool idea. We had that a while ago over on the HEROGames forums and it developed into a series of books (unfortunately due to funding problems only the first one got published).
You can find it here.

I am very interested what ideas you have in stock for the rest of the states.

Gold Rush is awesome

Awesome x3!

Bighorn, half-man, half-sheep and all raw power, is the representative from Colorado.
