Description: Emperor Grumm is an evil emperor and figurehead who serves as the de jure leader of the Troobians, an alien empire whose ultimate goal is to conquer the universe with his supposedly unending army.

Commander Kruger has battled him before and lost everything. Grumm over the years had conquered and slaughtered a large number of planets. Dr. Kat Manx's homeworld had also fallen to the Troobian Empire.
