In the anime, all of the characters, including Cassidy (though not as often) forget Butch's real name and calls him by a similar name, after which he gets into a fit. Dr. Namba: Dr. Namba (unseen, but seen with a silhouette) appears after the first couple of minutes in various episodes when Cassidy and Butch are sent for trouble. He orders the 2 rocket members to do all sorts of stunts via satellite chip (well placed usually in various foods), but his plans always fails some way or the other.
