The Jimmy Timmy Power Hour is an American trilogy of crossover television specials between the animated television series The Adventures of Jimmy Neutron, Boy Genius and The Fairly OddParents, consisting of The Jimmy Timmy Power Hour, The Jimmy Timmy Power Hour 2: When Nerds Collide, and The Jimmy Timmy Power Hour 3: The Jerkinators. The specials premiered on Nickelodeon between 2004 and 2006, and were subsequently released to home video. They combine multiple types of animation, using 2D computer animation for the segments set in the Fairly OddParents universe and 3D computer animation for the Jimmy Neutron segments. The events of the crossover specials take place during the second and third seasons of The Adventures of Jimmy Neutron, Boy Genius and during the fourth and fifth seasons of The Fairly OddParents.
Struggling with his science project, Timmy Turner wishes that he could be sent to the best laboratory in any universe. When his fairy godparents, Cosmo and Wanda, fulfill this wish, Timmy is sent to the town of Retroville in the universe of child prodigy Jimmy Neutron. Jimmy is sent to Dimmsdale in Timmy's universe when he accidentally activates a magical transporter created by Cosmo and Wanda. As they attempt to return to their respective worlds, Jimmy and Timmy meet the various side characters of each universe and Timmy becomes romantically involved with Jimmy's classmate, Cindy Vortex. While messing around in Jimmy's lab, Timmy accidentally turns Goddard, Jimmy's robotic dog, into a giant, violent monster from a video game he was playing. Timmy manages to stop Goddard from destroying Retroville, but is contacted by Jimmy, who tells him that Mr. Crocker, Timmy's fairy-obsessed teacher, has stolen the transporter, allowing him to take over Fairy World. Crocker is defeated by Jimmy. Both Jimmy and Timmy manage to return to their own universes. Back in Dimmsdale, Timmy realizes that he never finished his project, but at the last second, Jimmy teleports Goddard to the science fair, allowing Timmy to win.[1]
Jimmy and Timmy enter each other's worlds for a second time, both wanting to ask Cindy out to their school dance celebrating Friday the 13th. In an attempt to gain Cindy's affections, the two engage in a battle of smarts that sends Jimmy and his friends to Dimmsdale. As Jimmy seeks to prove that Timmy is a fraudulent scientist, Cosmo and Wanda struggle to keep their existence a secret from the people of Retroville. Meanwhile, Professor Calamitous, a major villain in Jimmy's universe, unleashes a surge of anti-fairies from Fairy World that threatens the rotation of Timmy's Earth. Jorgen Von Strangle, the powerful fairy commander and enforcer of Da Rules, gets increasingly frustrated by both Jimmy and Timmy's friends and their manipulation of fairy magic. In addition, Jorgen is forced to work with Calamitous after he is betrayed by the leader of the anti-fairies, Anti-Cosmo.[2]
In their third and final encounter, Jimmy and Timmy make amends while trying to defeat the enemies from their own universes—including a monster that they concoct together—while purposefully rejecting their respective friends in the process, including Cindy. Initially, they are unable to make the monster evil enough to fight them properly, but when they succeed, he almost immediately turns against them and absorbs Cosmo and Wanda's magic and Jimmy's intelligence, and then begins destroying both children's universes.[3]
Each special in the Jimmy Timmy Power Hour series combines the 2D hand-drawn traditional animation of the Fairly OddParents and the 3D computer-generated imagery animation of The Adventures of Jimmy Neutron, Boy Genius. This blending of animation techniques was a technical challenge for the studios responsible for both series, according to Keith Alcorn, co-founder of series producer DNA Productions.[4]
According to Variety, the first special was seen by nearly five million viewers on its Nickelodeon premiere, on May 7, 2004.[5] Terry Kelleher of People gave the first special three stars out of four, calling it a "blast of creativity" although hard to follow.[6] The Washington Post similarly gave it praise.[7] The network considered it a success.[8]
The second special, aired January 16, 2006, was seen by nearly 5.5 million viewers, according to The New York Times.[9]
The third and final special aired July 21, 2006. It serves the series finale of The Adventures of Jimmy Neutron: Boy Genius. For a while, it was also intended to be the series finale of The Fairly OddParents, until season six of that series was ordered for production by Nickelodeon.
