Ratthew

Trivia

 * Not actually trans, per-say (rats have no concept of gender). Simply put, the members of Mutie Zone assumed he was a dude (despite the lack of enormous testicles rats usually have), gave him a dude name, called him he/him etc, and then when he got pregnant, Ratthew being a trans icon became a running joke in the server.
 * The fact that his babies have wings proves that once someone mutates, all of their children will inherit said mutation.
