I didn't know about this thread until now, had a blast looking through it! Going to post a few of mine!
The first one is my namesake Citizenship, an older character that's very obviously based on a certain super... man if he was patriotic, he was my main though for a very long time on live so had to remake him here too!
Next up is Sandskin, a mutant whose skin indefinitely produces sand, he became a hero because his little brother thinks it's cool, and he secretly enjoys helping people too.
And finally my new main I think that's I'm loving a lot, his name is Flap, a mutant with wings that shoots arrow, simple but he's been a lot of fun both to RP and play.
