Monstro spotted Ariel and gave chase, intending to devour her whole. Ariel swam for her life, but found her escape cut off by a colossal electric eel. Getting an idea, Ariel returned to the surface, putting Hook's ship in between her and the leviathan. Taking the bait, Monstro crashed down the Jolly Roger in an effort to get to Ariel, sinking the ship and temporarily stunning Monstro. Hook and his crew managed to get to a lifeboat and head for shore as Ariel escaped in the confusion.
Vs Prince Eric
After escaping the destruction of the Horned King's citadel, Ursula returned to the seas to focus her efforts on rooting out Ariel and her allies. Meeting with Marina Del Ray, a corrupt former advisor to King Triton, Ursula tasked her with capturing Ariel's human lover Prince Eric to force Ariel out of hiding, even lending Marina the magic shell that gave her control of Monstro. Finding Eric's ship, Marina summoned Monstro to destroy the vessel, the whale's thrashing threatening to swamp it. Seeing Monstro charging, Eric took the wheel and tried to steer the ship out of Monstro's path. However, he was too late to prevent Monstro from ramming the ship, knocking Eric and the other crewmen overboard. As Marina and her eels captured the crew, Eric climbed up a loose rope back onto the ship and again tried to sail for safety. However, Monstro again proved faster, smashing the ship into splinters with a slap of his tail. As the crew who had managed to escape Marina watched, Eric sank beneath the waves, where Marina took him to Ursula.
In the sea, Pinocchio found Monstro, though not in the way he intended. Told by Flotsam and Jetsam of the puppet boy's arrival, Ursula commanded the great whale to devour him.
As McLeach was swept downriver to the sea, harried by crocodiles, something seemed to frighten them off. Turning, McLeach saw the rampaging Monstro approaching. Despite his struggle to escape, McLeach was swallowed alive by the leviathan, and unlike Pinocchio and Geppetto, he would not be escaping.
