Caeliostro is a mad scientist who has a laboratory in a tower in Massachusetts. It is very likely that his inspiration is scientist Albert Einstein and therefore, he spent years preparing for his experiment. At some point, he created a monster named Torgo and made him his assistant.
After creating a machine called The Metamorphitron, Caeliostro is now ready for his experiment. He orders Torgo to catch Timon and Pumbaa and bring them to him. When Torgo does so, Caeliostro tells the two friends that he is going to turn them into the world's most beautiful creatures. Timon then replies by telling the doctor that he is already beautiful, but Pumbaa could use some improvements. Therefore, Caeliostro puts Timon in a cage.
Pumbaa is getting ready to become beautiful and he is put in the Metamorphitron by Torgo. However, the Metamorphitron turns Pumbaa ugly instead of beautiful, much to Caeliostro's shock and depression as he realizes that his experiment failed. After telling Torgo to put Pumbaa in the cage with Timon, Caeliostro takes out a picture of Albert Einstein and asks him what he could have possibly overlooked. Albert Einstein "whispers" into Caeliostro's ear and tells him to check the math. Dr. Caeliostro tells Torgo that they have work to do and the two go upstairs.
Meanwhile, Timon and Pumbaa make a plan to turn Pumbaa back to normal and then escape the laboratory. After they succeed in getting out of the cage, while Pumbaa is getting turned back to normal, Timon gets caught by Torgo and tries to escape him. He gets in the Metamorphitron with Pumbaa and as a result, the meerkat becomes ugly while Pumbaa is back in his normal warthog form.
When Torgo catches Timon and Pumbaa, Timon makes a plan to have the monster be on their side in order for himself to get back to normal. Timon convinces Torgo that Caeliostro will soon replace him with another monster, causing him to be enraged and dislike the doctor.
When Caeliostro finds Torgo destroying the Metamorphitron and tries to get him to stop, the laboratory explodes and Torgo turns into a beautiful woman. This makes Caeliostro fall in love and decide to marry her and become the happiest man on earth.
Caeliostro is shown to have a blue-greenish skin with yellow eyes, a green nose, a mustache, blue hair, and pointy ears. He wears a green lab coat and boots.
Personality and traits
Being a mad scientist, Caeliostro is shown to have an evil side. His first experiment is to try to turn anyone beautiful, which in this case is Timon and Pumbaa. While his personality may be rather antagonistic, his work is not meant to be harmful and monstrous, considering his reaction when he sees Pumbaa being turned into an ugly creature.
When his assistant Torgo becomes a beautiful woman, Caeliostro decides to marry her and become the happiest man on earth. Therefore, it is possible that he has reformed.
