Computer is the sole CPU opponent of the USA exclusive Bust-A-Move Again replacing every opponent. The appearance he takes is something that would be made in the 80's- early 90's. His attack is going beep and boop like how a computer does. Other then all that he basically has no personality not even a win animation.
While he can't be played in Again he can be played in Puzzle Bobble 2x (using the code 1P Start + A + Up + Left in the arcade version) though be warned he uses the cannon instead of the shooter!
