my female character suggestions range from a little obscure to super obscure so they wouldn't net you a million lines in comic-verse terms, but they also don't have tons of backstory to catch up on so it's a tradeoff? carol bucklen, anita fite, and arrowette (who the rest of the young justice crew would be thrilled to see, i'm sure). ooh also cassandra cain. and i know tumbling is looking for maggie sawyer. i'm sure there are awesome ideas i'm missing...
but whoever you choose, i'd be happy to figure out a line with you!
