Ajax

as a part of an experiment, Ajax had his DNA mixed with that of a gorilla.  With his strength, he can knock down a building if he wanted to.  He might seem like a brute, but he's actually quiet smart and introverted.  He mostly likes to hide in his box (don't ask how he fits) to keep to himself, often reading.  If you bug him, you'll likely get an uppercut that'll send you flying
