Disney Vs Marvel Villains War
Dormammu tries to gain an advantage in the war through the shadows, having his acolyte, Baron Mordo, recruit Venom to his cause. His two acolytes manage to free him, but his triumphant return is cut short with the arrival of Hades and Doubt. Dormammu uses his laser vision to pummel Doubt to death with a boulder. Dormammu is far less prepared to stop Hades, who uses Ursula's trident to cast both Dormammu and Venom into the netherworld.
