Non Disney Villains Tournament
After the death of the Wicked Witch of the East, Gloom and his partner, Truckle, join forces with the Wicked Witch of the West. The two are pitted against Chase Young and Drago, two apprentices of the demon, Aku. Gloom faces down Drago, but his lack of a corporeal form prevents him from putting up much of a fight. Indeed, but one flame attack from Drago is enough to send Gloom packing.
Humiliated, Gloom heads to the Wicked Witch of the West and asks for a human form. She complies, giving him the body of Zarm.
