Mongul's warriors are legion. Skilled in conquest and combat, they don't find many things funny. That became a problem when Mongul brought the Joker to his cruiser to entertain them or die. Nothing worked until the Joker zapped Mongul with his joy buzzer. They all gasped then broke into laughter. Warriors stationed at the docking bay encountered Wonder Woman and were thrashed. Mongul and Superman's battle spilled into the cruiser's arena. The warriors implored them to fight. Superman later returned to the cruiser and exhaled all of the Joker's 50,000 tons of Super Laughing Gas inside. Mongul and all of the warriors couldn't stop laughing.
