He is half Elf. He is quite confident but sometimes acts childishly. He at first looks down on Verne due to his "mortie" status, but Verne manages to redeem himself.
It is revealed in "Magical Quest" that he is related to a werewolf. Because he is half elf he is attracted to anything shiny, and when he sees something shiny, he goes, "Ohhhh sparklies". This usually makes Verne have to pull on his hood to keep him out of trouble. He has the ability to imitate voices without the assistance of magic. Gus's family symbol is a green star which is displayed on his shirt.
