Paladins often makes parodies from popular culture, and this guy seems to be a parody of Rocket Raccoon from Marvel's Guardians of the Galaxy. One of the few non-human champions, I wasn't a big fan of him.
He has a potion launcher which acts like a grenade launcher. It actually is more useful to heal allies than it is to hurt foes with.
His special move will turn enemies into chickens. While funny in a way, it's not very useful. I've been turned into a chicken a few times, but I only died once during the chicken form.
He's not the worst champion, but I have no desire to play a match as him ever again.
