He first appears as a sewer deity and nearly eats Charlie B. Barkin but Charlie's high pitched howls amuse King Gator who spares Charlie and becomes his friend, swimming him and Anne-Marie to the town. He later appears, hearing Charlie's howling, breaking into Carface's ship and frees Charlie. Under orders from Charlie, King Gator repeatedly rams the ship to free Annie. When Carface falls into the water, King Gator saw him as a meal swims after Carface, eating him in an offscreen bite.
At the end of the film, Carface appears in Heaven, having been eaten and vows revenge.
Trivia
King Gator was voiced by Ken Page, who also voiced Oogie Boogie from Disney's The Nightmare Before Christmas.
