The manual only included 1-6. I'll tell you what I can remember.

Zoonik is a purplish hedgehog who runs around at high speeds. He has a gun which shoots almost invisible yellow pellets, he can teleport, his graphics are pretty cool, and his life bar is pretty decent even on Easy. If he had been given better AI, and/or the ability to jump, he could easily have been a very formidable opponent.
