Bubby is a crass, idiotic, egotistical, and impulsive scientist. Bubby was created inside Black Mesa by scientists slapping chemicals together until they created a person, The Ultimate Life Form, and promptly had knowledge injected directly into his brain; Bubby also claims to be six years old. He has a special ability: to become a flaming wheel and launch himself at things, like Shadow the Hedgehog. He can also turn into a car. His favorite type of bread is Garlic Bread. He has always been old.
