Patrick Spinel is the secondary antagonist of the 1998 animated film, Don.
Originally, Patrick Spinel had a goofy, fun-loving and a rather innocent personality, being Don's adoptive brother to the point of being clingy. She greatly enjoyed her time with Don and viewed her as his best and only friend. This friendship turned into practically undying loyalty, as he did not hesitate to wait 50 years for Don when he was told by the Guardian it was part of a game. Until one night, he was altered by one big spider bite over the course of ten years, which resulted him into becoming actually a crazy, pompous, deluded, greedy, arrogant, selfish, delusional, and overly determined creature.
However, upon seeing the Guardian's message, he realized that Don had completely forgotten about him and started a new life with family and friends and left Spinel alone, not even bothering to join him to go to the attempted theft of the Magic Emerald and currently tell him that Don didn't want to bring Patrick with him. Upon realizing this, Patrick was heartbroken and brought to tears, utterly devastated with this information.
It was because of this event that he became filled with unyielding rage and hatred. Out of spite and anger towards Don and the other lemurs for their close relationships with the Guardian, he decided to get a drill with poisonous bile that would destroy all organic life on Earth. While fueled by rage, he still retained his humor and jovial nature, even while fighting the lemurs. He took sadistic joy in knowing that the island of Madagascar would be destroyed and stated that after knowing Don, he wanted to kill him even more.
Upon hiding his more evil nature during his return to Earth, he still longed for a friend, and upon seeing that Don was willing to be there for him, he decided to stop his plan at destroying the Earth and became momentarily redeemed, but once again return to his former evil self and resume his destruction of all organic life on Madagascar, due to the Guardian's evil plan.
Patrick saved a lemur, Don, as he was about to crash into an asteroid field and teamed up with his past self to venture to the Systar System and save his friends from the DUPLO Aliens. As they continue on to the Systar system with some of his toy buddies, Don begins to take on several of Patrick's mannerisms, hoping to impress Lisa. When they arrive, they evade capture by the DUPLO's forces by swamp creatures and "brainwashed" of most of the people by singing "Catchy Song".
Outside, Don is reunited with Lisa and they embrace, but not so much when she meets Patrick. Patrick tells Emmet that he has managed to have his own abilities and force by making him tough. Despite Don's joy of this by impressing her, Lisa is sort of disappointed by this. Once they escape for the Duplo Brickyard, they make up a plan which involves switching off the pop music that is brainwashing the others, while Don will destroy the reception cake encased in a temple to stop the wedding between Batman and Wa'nabi. However, Patrick and Don are shocked when Lisa reveals her original hair to them, and she affirms it's her real hair and that she was not brainwashed. Despite Patrick's warnings, Don believes is the real Lisa because he trusts her, and she helps them to the plan.
Before Don could follow the plan by disguised as a knight, Patrick gives him his own vest, and Emmet thanks him for helping him, without knowing yet his true intentions. Despite Lisa's warning after she knows the real intentions of the DUPLO people, Don destroys the reception cake at the wedding between Batman and the Queen of the DUPLO Aliens, Watevra Wa'Nabi. Don soon realizes after learning that the DUPLO Aliens only wanted peace between themselves and Bricksburg and seeing a hole in the universe appear in wake of the cake's destruction.
Feeling betrayed, Patrick revealing his true colors as Don's ex-brother and enemy, reveals that he wants revenge on Don for killing his parents and dump him in the orphanage, as he now became abused, unloved and unadopted (by Don having Patrick used for his money).
The two begin to fight in the top of Statue of Liberty and Patrick knocks Don under the cage so that he will now have revenge. However, determined to not become like Patrick, Don returns to the Systar System when Lisa, having rallied the other lemurs into successfully escaping from the greedy zoo manager, arrives in front of Patrick and they both embrace. Patrick thinks they are too late and attempts to go back in time, but Lisa manages to trick Patrick into punching a cute sentient heart, triggering an explosion, destroying the piece that is part of his time machine and Patrick topples in defeat. Lisa then tells Patrick that Don will not become like him, and admits him for breaking his brother's friendship, but Don throws a boulder on Patrick Spinel's head from behind, instantly knocking him unconscious and sending him falling out of the Statue of Liberty.
- Despite being the secondary antagonist of the film, an increasing group of fans sympathize with the character, mainly because his (initial) dim-witted and charismatic nature and the feeling that Don undervalued him.
- In a way, Patrick Spinel actually serves as the deuteragonist of the film. He was the one that ultimately funded a way to save the lemurs from the certain death. Sure he was angry at some parts when he was the deuteragonist such as his screaming NO! at Don when he said that he had to stay with the other lemurs instead of stealing the emerald for profit. Thankfully, he should be considered the true deuteragonist of the film and not the rest of the lemurs for the most of the film.
