Gatto is a selfish and unpleasant being; he accumulates treasures only to attract others and devour them. He is capable of devouring his own subordinates without reason.
After learning than Gatto possessed the Birthstone of Gunmar, Jim Lake Jr., Toby Domzalski, Claire Nuñez, Blinky, and AAARRRGGHH!!! go to get it. When the group first meet Gatto, he gives them a challenging riddle to determine if they get what they came for, or if he gets to eat them. The riddle is, “What begins but has no end, and ends all that begins?” Although Claire managed to solve it, Gatto devoured Toby and Blinky, not wanting anyone to tell about his riddle. However, both managed to find the Borthstone in his stomach and gave him indigestion in order to escape.
Later, the same group of people/trolls stole the Kairosect from him, as well.
Gatto is shown as a member of the Troll Tribunal. He attends the meeting using a projection of his face made of floating rocks.
