Demongo is a minor villain in the television series, Samurai Jack, and a minor player in the second Disney Vs Non Disney Villains War.
Vs Pain and Panic
Aku and Eris send Demongo out to kill Hades's sidekicks, Pain and Panic. Demongo trails the two to the River Styx and attacks. He throws a skull, injuring Pain, and then blasts Panic, who promptly spikes Pain's rear end with his pointy ears. Demongo cannot help but laugh. He sears their flesh with fire, but the two survive and shoot some arrows at Demongo. Demongo burns the two some more, but Chaos appears and stops him. Chaos frees all of Demongo's souls and leaves the demon a withered husk. Demongo crawls back to Aku and begs for a second chance, only for his master to execute him.
In Hell, Aku was enjoying his reign over his new domain. He was not able to enjoy it for long, however, as he was interrupted by the arrival of a powerful sorcerer known as Skullmaster, who challenged him for the throne of Hell. Not wanting to dirty his own hands at the moment, Aku summoned his top minion, Demongo the Soul Collector, and ordered him to destroy the intruder and collect his soul. Skullmaster, however, was thoroughly unimpressed by the demon and mocked him. Demongo, eager to please his master, attacked Skullmaster by throwing a skull projectile at him, only for Skullmaster to block it with his sword. Demongo quickly followed this attack with a blast of magic, stunning the sorcerer. However, Skullmaster merely shrugged off the attack, and retaliated with a powerful spell. The attack greatly weakened Demongo, causing the various souls stored in his body to leave him, thereby draining him of his power. With Demongo reduced to a small withered husk, Skullmaster simply crushed him in his fist.
Vs Bill Chiper
Aku send Demongo to kill Bill Chiper before he could be a threat for Fire Nation. Demongo tried his best to defeat Bil, but he decide to finally killed him in front of Aku.
