Although most adults, even those as dumb as Timmy's parents, simply do not believe fairies exist, Denzel Crocker believes otherwise. He has been shunned by his colleagues and students alike, and yet despite his clumsiness, he is actually one of the smartest characters on the show. He has correctly second guessed Timmy's usage of his fairies a number of times, and has invented a number of devices that can actually sense magic and fairies, although they are usually destroyed by either Timmy, Cosmo, Wanda, or Poof. He still lives with his mother, Dolores-Day Crocker, and his house is decrepit and run down. Mr. Crocker's room is filled with photographs of wands, newspapers, and pictures of fairies. He has an old computer in the middle of his room which also has a web camera. He even has his own hideout called the Crocker Cave.
Denzel Crocker worked at a number of different schools and colleges before ending up in Dimmsdale Elementary School. He was once an aspiring professor for Dimmsdale University, but his proclamation of his belief in fairies led to him becoming a laughing stock in all the city of Dimmsdale. He was also kicked out of a New Baltimore Community College for spending money on fairy tracking inventions. Even after landing a job in Dimmsdale Elementary, he was still scorned and laughed at by his colleagues, including Principal Waxelplax.
In Crocker's past life, he was an adorable and kind child who enjoyed helping others. His mother was never around very often and got babysat by Vick. Because of this, he was very miserable. However, his sadness ended after having received his own Fairy Godparents, Cosmo and Wanda.
Unfortunately, after Timmy time travels to the year 1972, Timmy and Cosmo accidentally reveals Crocker's secret about his fairies in front of the whole town who had gathered to celebrate a day honoring Crocker. Because of this, Jorgen Von Strangle is forced to erase Crocker's memory of him ever having fairies, and because of an overdose from the memory wiper, Crocker becomes horribly disfigured, and the town's people, who had now completely forgotten all the nice things that Crocker did with his fairies, assumes that they must be an angry mob and chased him down. He remembers nothing but he finds a DNA tracker device that Timmy left behind in the past on which he wrote 'Fairy Godparents exist' on the back before his mind was wiped, Crocker uses it to try and find real fairies. Timmy later wanted to return back to March 14, 1972, but he was stopped by two Jorgen Von Strangles (1970's version and current version). After that, the event ends with Jorgen and his other self dancing on the dance floor 1970's style.
Life as a TeacherCrocker's life of a teacher is comical in a way that Timmy's principal, Geraldine Waxaplax beats him up for such situations such as going in to the girl's bathroom. He had to switch jobs three times, changing into a ham salesman, a tour guide in the episode Nega Timmy, and a crossing guard in the episode No Substitute for Crazy!.
His family includes his mother and his uncle. His uncle is obsessed with genies and owns a collection of lamps. One of which contains Norm the Genie, although he is kept safe so his craziness is stable. His mother is a polite person, once rich and groovy. But when Crocker was young, she was non-attentive, pretty much like Timmy's parents. Crocker's father is never seen in the series, not even in The Secret Origin of Denzel Crocker, where his childhood is revisited, suggesting Crocker lost him at an early age or that he never had one. This lack of a father figure is implied to be the reason Crocker quickly accepted his stepfather, Ricky, from The Odd Couple as his father and even wanted to play childish games with him and having an allowance.
When Denzel has anything involved with Fairy Godparents or suspects there's one around him, or even says the word, Denzel spasms three times (each spasm spoken with "Fairy", "God", "Parents") while saying 'Fairy Godparents!' His appearance isn't that of a normal human being, having ears on the neck. Denzel is often considered crazy due to his constant obsession of fairies. In his early childhood, Crocker was kind, brave, and handsome. Due to losing his fairies, he is unattractive, having cricked teeth, a hunched back, and his ears on his neck. If Timmy hadn't affected the timeline, Crocker would be a handsome college professor.
Role in the Movies
Mr. Crocker acted as the main antagonist in the first TV movie Abracatastrophe. In the film, Mr. Crocker often tried to get his hands on the Fairy-versery muffin that could grant any wish. He chained Timmy to his desk so that he wouldn't recover it from the cafetaria during Muffin Monday, but Bimpy took a bite out of the muffin instead and wished for monkeys to rule the world. After insulting monkeys at the jungle version of school, the gorilla overlords took Crocker to a human experiment lab. It was mentioned that his favorite food is shrimp puffs.
After the world turned back to normal, Mr. Crocker finally got his hands on the muffin and wished to capture Wanda with an indestructible butterfly net. He trapped Wanda in his scepter used her magic to make himself a powerful dictator and took complete control of the world. During a long showdown, he managed to capture Cosmo too and later realizes that he'd been fighting Timmy Turner the whole time. Mr. Crocker went to the Turners house, captures Timmy's parents, and threatens Timmy that he'd turn them into ice sculptures and transport them to the sun if he didn't surrender. This causes Timmy to ultimately reveal his godparent's existance and have them sent to fairy world, cutting off Crockers magic as well as being attacked by Timmy's parents.
After the world went back to normal (again), Mr. Crocker was seen at the school making outbursts about ruling the world and gets sent to a mental institute.
Jimmy Timmy Power Hour
Mr. Crocker was the main antagonist in Jimmy Timmy Power Hour. He was seen in the classroom talking about the upcoming travel-related science fair. When Jimmy was stuck in Timmy's universe, Jimmy eventually developed a transporting device with Timmy's poofer and game-buddy. Mr. Crocker however, bursted in Timmy's room, took the device from Jimmy, and used it to enter Fairy World. After breaking into the weapons room, Mr. Crocker knocks down the Big Wand and cuts off the fairies magic and turned Jorgen Von Strangle into a dog. When Jimmy succedded into fixing the Big Wand, the fairies recovered their magic. Crocker was blasted by Jimmy a few times and then gets mauled by Jorgen's dog fangs.
Role in the Games
Crocker appears in the crossover game Nicktoons Unite! as one of the main antagonists. As a member of The Evil Syndicate, his duty is to drain the Fairy World out of it's magical energy and feed it to the Doomsday Machine created by the villainous group. The heroes face Crocker at Fairy World's "Big Wand", the main source of fairy magic, where he tried to destroy the group by using some sort of robotic arsenal. But even using the Big Wand's power wasn't enough to prevent his defeat, which forced him to retreat. He then joined the other villains at Professor Calamitous' lab, where he faced Timmy, his fairies, and his friends again, attacking them while protecting himself behind a shield made of fairy energy. But once again, Timmy managed to defeat him by disabling his shield and attacking him, defeating Crocker, and soon the rest of the Syndicate.
Role in the series
Crocker makes his first big debut in the SAF series as a Villain Leaguer in Nicktoons Reunited. Ever since, he is told that Timmy does indeed have fairies by the villains who clearly already know it, and thus Crocker is always going to be made aware again even after people like Jorgen von Strangle erase his memories of such a thing since he is a part of the world under his jurisdiction.
