Marquis Pablo is an aristocrat played by Pablo.
When he, Duke Tyrone and Prince Austin were gathering supplies needed for survival, the indestructible dome around the castle had vanished. It turns out that Pablo had sabotaged the handheld device that holds the dome's power. And it also turned out that he created the virus. And he also has a device that can summon zombies to their location. He was jealous of Prince Austin and his siblings and wanted to be the ruler of Monroe. So he created a virus to turn the residents into zombies as a way of making them his slaves. When the zombies arrived, he orders them to capture Prince Austin. But suddenly, he was tackled from behind by Duke Tyrone, who later smashed the controlling device and tossed Pablo into the zombies, forcing him to be bitten and become a zombie instead. Without the device, the zombies have gone berserk. After the zombies were cured, the army arrested Pablo and he was given glares by Prince Austin, Prince Victor, and Princess Jordan. Feeling ashamed of his actions, Pablo apologized. He acts as the true antagonist of the episode "The Royal-pocalypse".
Marquis Pablo is mostly of a blue color.
