Grendel is the son of the most decorated hero in the history of the Confederation. Long neglected and considered a disappointment by his legendary father, Grendel set out to prove himself by becoming a hero in his own right, first with the Meowing Commandos and later with the CH-13. Grendel is the consumate soldier, as serious and hard on his fellow Hellcats as his father was on him. He is currently a Colonel in the Transuniversal Intergalactic Tranquility Squadron and the right hand of Admiral Kitty. Unlike most felinoids, who have the species designation felinoid sapien catus, Grendel is felinoid panthera leo, making him somewhat larger and more imposing than most felinoids.
