Jimmy Timmy Power Hour
Jimmy: Jimmy Neutron, boy genius.
Timmy: Timmy Turner... boy!—The title characters introducing themselves to each other
The Jimmy Timmy Power Hours are a trilogy of hour-length specials produced for and aired on Nickelodeon in 2004 and 2006. As suggested by the title, they are a series of Crossovers between two of the network's most popular cartoons, The Adventures of Jimmy Neutron and The Fairly OddParents.
It all starts in the first special, when Timmy, in need of a good science project, wishes to go to the greatest lab in the universe, and Cosmo and Wanda transport him to Jimmy Neutron's secret lab. An accidental meeting between the two results in Jimmy getting transported to Timmy's world, where he mistakenly believes Cosmo and Wanda are holographic supercomputers (because he thinks Timmy is also a genius), and Mr. Crocker steals his transportation device, which he then uses to take over Fairy World. Back in Retroville, Timmy develops mutual affections for Cindy Vortex and accidentally turns Goddard into a killer robot. The boys eventually manage to solve their respective problems and return to their own worlds, and all ends well...
...Until two years later, when the second installment, When Nerds Collide!, came out. Timmy is looking for a date for the Friday the 13th school dance, and since Trixie Tang isn't around for him to unsuccessfully ask out, he goes to Retroville again, this time taking Cosmo and Wanda with him, so he can get Cindy to go out with him. This naturally does not sit well with Jimmy. As if that weren't enough, Professor Calamitous is on the loose again, and so are the Anti-Fairies.
Finally, in the third special, The Jerkinators!, Timmy and Jimmy put aside their differences and start hanging out together. They grow bored with their outmatched villains and create a new villain to fight. But things take a turn for the worse when this new villain, named Shirley, steals Cosmo and Wanda's magic powers and Jimmy's intelligence!
Outside of these specials, Jimmy and Timmy would join forces a few more times in the Nicktoons Unite! video games. See also Rugrats Go Wild for another Nicktoon crossover.
- Art Shift: Characters go from hand-drawn to CGI and vice-versa in each other's worlds.
- The "B" Grade: Crocker, mistaking Jimmy for Timmy, gives him an F, which burns his hand.
- Continuity Nod: Jimmy mentions in When Nerds Collide! that Professor Calamitous must have escaped the time of dinosaurs, where he was left with several other Jimmy Neutron villains in "League of Villains".
- In the first special, Cosmo and Wanda introduce themselves to Jimmy the same way they did to Timmy in the Fairly Oddparents pilot.
- Fluffy the Terrible: Shirley in The Jerkinators.
- Four-Fingered Hands: The Fairly Oddparents characters get an extra finger on each hand in Jimmy's world, while the Jimmy Neutron characters lose a finger in Timmy's world.
- Grand Finale: The Jerkinators! was intended to be this for both series. However, Fairly Oddparents got Uncancelled, and Jimmy's show got a Spin-Off (Planet Sheen).
- Hypocritical Humor: "How does he do it, magic?"
- Love Triangle: Jimmy/Cindy/Timmy
- Insufferable Genius: AJ in the first special.
- The Other Darrin: This was enforced in Latin American Spanish because The Fairly Oddparents was recorded in Miami and Jimmy Neutron in Mexico. The first special used Mexican actors, while the sequels were recorded in Miami.
- Running Gag: In the second special, Timmy running behind trees to "invent" stuff.
- Shout-Out:
- Talking to Herself: Timmy and Libby were already voiced by Anna Sztejner in Polish.
