Bounty Bug is a humanoid grasshopper alien wearing a long desperado-styled coat. Underneath the coat is a full body armor suit that covers his whole body except his arms and eyes. He wears a top hat with goggles wrapped around the hatband and holsters two pistols on his thighs. He is also equipped with a molotov which he throws at his opponent when using his Desperado attack though this becomes a chain gun when upgraded, which are both concealed.

Yee Haw! This gun slinging grasshopper may seem far from home, but he's taken up a permanent residency in the hearts and minds of fans worldwide. Bounty Bug is one mean hombre...and stylish to boot!
- The elite versions of this mutant gain a belt buckle which showcases the star that was used in its crossbreeding.
- He, along with Honey Bunny, are the only two mutants so far to have been featured in two different Reactor collections (in this case, he appeared in the Steampunk Reactor and the Space Wars Reactor).
- His appearance might have been inspired by the character Cad Bane from Star Wars the Clone Wars series as it shares several similarities with him.
- Both are bounty hunters.
- Both wield two pistols.
- Both wear a hat and have similar style coats.
- The Gold version's hat and attire look similar to ones worn by Apollo Creed in the Rocky movie.
- His Space Wars Reactor skin is a reference to Han Solo, from Star Wars.
