Stromboli

Stromboli is the name given to the fierce puppet-master and one of the five antagonists featured in Disney's 1939 / 1940 animated adaptation of the fairytale Pinocchio and the main antagonist in the 2000 semi-remake Geppetto.

Pinocchio
At first Stromboli portrayed himself as a large, but friendly man who wished for Pinocchio to perform in his show, which Pinocchio did with glee (in his famous "I have no strings" melody).

However, after the show had finished, Stromboli showed his true nature when Pinocchio wished to return home to Geppetto (though he would be back in the morning). Stromboli declared Pinocchio was "home" and threw him into a cage, threatening to chop the puppet into firewood when he became too old to perform.

Pinocchio was freed from the cage by the Blue Fairy and Jiminy Cricket but is scolded for lying to the Blue Fairy and ignoring Jiminy Cricket's advice. Stromboli is not heard of again following this encounter and is presumably still performing his stage shows, minus his former star attraction. Without it, his show presumably bombed and caused him to go bankrupt after discovering that his star attraction is missing.

He does have a bit of a temper, and often loses it. He tends to say bad words in Italian whenever he loses his temper.

Personality
Initially, Stromboli seemed like he was a fun-loving, charismatic, but slightly moody puppeteer. Later on, however, he was revealed to be a complete psychopath, and (foolishly) revealed to Pinocchio that he would use his chopped up body as firewood. So Stromboli fits the classic bill of psychopathy, seemingly charming, but being greedy and caring for no-one but himself. Despite only owning a van full of dolls, as opposed to a castle and undead army, Stromboli managed to terrify many generations, with his murderous and infanticidal declarations and hot-blooded temper.

Geppetto
"We've got to find Pinnochio before it's too late. Well, you know what happens to little boys on Pleasure Island. You don't want me to find him do you? Well, this time, I'll chain him up so he would never escape. And you, you'll be nothing more than firewood *laughs* Shh..."

- Stromboli to his ventrioloquist dummy

In the live-action semi-remake, Geppetto, Stromboli was played by Brett Spiner (Data on Star Trek: the Next Generation). Here, he is depicted as an arrogant, greedy, stupid, clumsy, dishonest, selfish and cowardly bully who constantly argues with his ventriloquist dummy.

In the movie, after learning that Pinocchio was a stringless puppet, Stromboli asked him if he liked to sing and dance. Geppetto refused to let him get involved in show business and that he shouldn't talk to strangers. After getting in trouble, Pinocchio runs away from home to live with Stromboli as well as performing for his puppet show.

After the show, Stromboli and his ventriloquist dummy were counting the money made from the show. Pinocchio was seen locked in a cage. Stromboli refused to let him out, because it's a dark, cruel world out there and, more importantly, it's part of the contract he signed. When Geppetto came by, Stromboli covered Pinocchio's cage with a quilt and hid him outside. He lied Geppetto that Pinocchio went off on his own. After he left, Stromboli discovers that Pinocchio DID wander off and learns that he was headed to Pleasure Island. Knowing what really happens there, Stromboli and his dummy went off to retrieve him before his father does.

Later, the Blue Fairy shows Geppetto what Stromboli is really like and what he really wants from Pinocchio. At Pleasure Island, Stromboli followed Pinocchio around, but the Ringmaster tells him that adults aren't allowed there. When Pinocchio tries to get on the rollar coaster, Geppetto and Stromboli were fighting each other, only to have the fight broke up and that Stromboli was escorted out of there.

Back in the toyshop, Stromboli had been waiting for them and that he showed Geppetto the contract Pinocchio signed. He pushed Geppetto aside, ransomed Pinocchio, and went off. After the Blue Fairy turned him into a real boy, Stromboli realized that no one would pay to see a real boy. In the end, he was repeatedly attacked by the Blue Fairy and fled.

Trivia

 * Despite his limited screen time, Stromboli went on to become one of Disney's most infamous and acclaimed villains.
 * Stromboli is very similar to fellow Disney Villain Mother Gothel. Both have locked up the main protagonists of their respective films for their own selfish interests, acted charismatic, and when the protagonists (Pinocchio for Stromboli, Rapunzel for Gothel) protest, they'd yell at them. Their names also originate from European countries (Gothel is German, and Stromboli is Italian).
 * He is unique among Disney Villains, as he has no evil henchman to do his evil bidding, that is, except for Honest John.
 * In some pages of a comic book named Disney Classic Cartoon Tales, which holds The Lion King, Pinocchio, and Bambi, his name is sometimes misspelled as Stomboli.
 * He is similar to Cecil Clayton from Tarzan, Lyle Tiberius Rourke from Atlantis: The Lost Empire, King Candy from Wreck-It Ralph, Prince Hans from Frozen and Professor Callaghan from Big Hero 6 (though Callaghan was a good man but later turned into villainy instead of being a hyporcrite all along). They each didn't appear to be evil at first, but as the films progress, their true twisted natures were revealed.
 * Chronologically, Stromboli was the first Disney movie villain to share that trait.
