Monstro

Monstro is an enormous whale and the final antagonist in Pinocchio. While Pinocchio spends the night in Stromboli's troupe and, later, Pleasure Island, Gepetto searches for his son. Taken to sea, the toymaker, Figaro and Cleo are swallowed whole (complete with a boat) by Monstro. The whale later swallows Pinocchio, when the little wooden boy comes searching for his father. Monstro has a reputation as a "whale of a whale" and is feared by all the creatures of the sea, and apparently on land, as even Jiminy knew of him and of his deeds.

Design
Joe Grant's Character Model Department was responsible for the design of Monstro the whale. Models were constructed both of Monstro himself and of his belly,complete with skeleton. In addition,inspirational sketch artist Gustaf Tenggren created a watercolor image of Geppetto in Monstro's belly.

Animation
The animation of Monstro was originally to be assigned to Vladimir Tytla (animator of Doc, Grumpy, Stromboli, and, later, Yen Sid, Tyrannosaurus Rex, Chernabog, Dumbo, and Friend Owl), but, perhaps out of worry that Tytla might get carried away, Disney eventually assigned Wolfgang Reitherman to the task. He animated Monstro as a cunning creature with a brain, making his pursuit of his prey all the more frightening. To Reitherman can also be attributed, to an extent, the timing and staging of Monstro's chase sequences, which were timed to suggest the whale's great weight and power. Reitherman drew a set of sketches for a discarded sequence showing Monstro consuming Gepetto's boat; Monstro was to emerge suddenly on the otherwise serene sea scene, first looking like a large mound before revealing his teeth and swallowing the boat in one movement before disappearing underwater once more.

Asleep
Monstro is first mentioned in the film when Pinocchio and Jiminy Cricket receive a message from the Blue Fairy who is in the shape of a dove that the whale has swallowed Geppetto, Figaro and Cleo when the toymaker took to sea to rescue Pinocchio from Pleasure Island. The three are still alive, inside Monstro's belly. Against Jiminy's warnings, Pinocchio resolves to find and rescue Geppetto. Though Jiminy tries to dissuade Pinocchio, warning that Monstro is "a whale of a whale... he swallows ships whole!", he does not hesitate to join the wooden boy in his search at the bottom of the sea. The two search for Monstro; mention of the whale's name causes the sea creatures to flee in terror. Meanwhile, in Monstro's belly, Geppetto and Figaro are trying to catch fish to eat. The toymaker tells Figaro that he fears that they will starve in the belly of the sleeping whale.

Swallowing Pinocchio
Monstro wakes at the sight of a school of tuna swimming nearby. Opening his great eyes, the whale pursues the fish with his mouth open, tearing through the ocean. When Pinocchio sees Monstro approaching, he flees for his life, pushing past the tuna, though he is nevertheless consumed by the beast. The sprightly Jiminy escapes the creature's jaws, but, on discovery that Pinocchio has been swallowed, tries to enter Monstro's now closed mouth. Jiminy tries to get in but he won't open his mouth. Inside the whale's belly, Pinocchio, reunited with his father, proposes that they escape in a raft (constructed by Gepetto) when Monstro opens his mouth. When told that "everything comes in... nothing goes out" of Monstro's jaws, the wooden boy suggests that they start a fire to make the whale sneeze.

The Chase
Monstro once again opens his eyes, this time to find smoke rising from his blowhole. He begins taking deep breaths; while his mouth is open, Pinocchio, Gepetto and the pets try to escape; they succeed when Monstro finally sneezes, sending them flying out to the sea. After another powerful sneeze, an enraged Monstro pursues the raft while Pinocchio and Gepetto row for their lives. Monstro dives underwater and emerges underneath the raft; Pinoccho and his father row away in time, but when Monstro leaps after them, they are forced to jump into the sea. The whale smashes the raft into pieces with his tail. Pinocchio saves his father from drowning and pulls him to shore, with Monstro in hot pursuit. As the whale builds up speed, the waves drifting from the cliffs of the shore hinder Pinocchio. Monstro leaps into the air, aiming to consume and kill the two. Finally, paddling madly, the wooden boy swims through the hole in the cliffs just as Monstro smashes into a giant cliff, the impact of which sends Pinocchio and Gepetto flying onto the beach. As the toymaker comes to, Jiminy, Figaro and Cleo are washed onto the shore. Pinocchio, however, didn't survive the blow. The puppet is later revived, and turned into a real boy, by the Blue Fairy.

Role in Ultima
In Ultima, Monstro was revived from his lethal impact by Maleficent, who used her dark magic to make the whale obedient to the Organization and made it a undersea juggernaut/battlestation/super weapon in her war against the Society, Acolytes, and Conquerer Armada.
