** Another is a loop of [[https://youtu.be/o_UIkS5m9gc?t=21s a heavy metal song]], seeming intended for some part of the Egyptian levels, given the file name. The song had an ancient Egyptian-themed cover.
** There's also [[https://youtu.be/5gZEazqtJAM?t=8s another heavy metal song]]. The file name is incredibly generic (musictemp), so no explanation can be easily extrapolated.
** Finally, there's [[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius the show's]] theme song, which makes more sense.

--> Jimmy: "All right! Radar!"

Back at the museum, [[TheRival Cindy Vortex]] is fascinated by an exhibit on a theory concerning time travel, which Jimmy claims is full of gaps. Being a boy genius, he then shows that he has the theory perfected and, using a conveniently placed portal, attempts to go back 50 years. Negatron detects this and intercepts the signal, diverting it into a cage in his lab. Negatron explains that he intends to take Jimmy's place and change his dimension [[ForTheEvulz just for fun]]. He leaves his large robotic henchman, [[Franchise/Terminator the Herminator]], to guard his prisoner.

->'''{{Narrator}}''': "Oh, but it can be. And somewhere, in another dimension, things are different. ''Very'' different. [...] In this other dimension is a boy named Jimmy Negatron: evil boy genius. And if this boy has his way, things ''will'' change in Retroville."

* AbnormalAmmo: Jimmy invents [[ItMakesSenseInContext a water balloon launcher, a fast food-launching slingshot for his rocket ship and an aptly-named burp-launching burpzooka]].

* WhatCouldHaveBeen: Given what's in the game files, it's possible that Negatron was originally named Johnny Newman. "Numie" may have been his nickname.

'''Jimmy Neutron vs. Jimmy Negatron''' is the sequel of sorts of the [[VideoGame/JimmyNeutronBoyGenius video game adaptation]] of the [[WesternAnimation/JimmyNeutronBoyGenius animated film]]. The game follows a more linear storyline than its predecessor.

At the start of the game, the eponymous PlayerCharacter, [[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]], is attending a class field trip to the Retroville Museum. He quickly finds himself bored silly by his teacher's lecturing. Thoroughly fed up with it, he exclaims, [[IJustWantToBeSpecial "Can't anything ever be different?!"]]

!!Jimmy Neutron vs. Jimmy Negatron contains examples of:

* BeardOfEvil: Negatron's goatee, which is a [[ShoutOut blatant reference]] to [[EvilTwin Mirror!]]Spock's goatee in the classic [[Series/StarTrekTheOriginalSeries Star Trek]] episode [[Recap/StarTrekS2E4MirrorMirror Mirror, Mirror]].

--> ✅ Dominate Jimmy Neutron's dimension.

* ShoutOut: The King Carl level is a parody InNameOnly of Film/KingKong. [[http://i.imgur.com/RrHU7Bo.jpg The loading screen for the level]] extends the reference a bit further.

-->Negatron: "Hermin!"

* CastFromHitPoints: The submarine and the rocket's speed boosts and the Water Gun and virtual reality tank's ammo (except when using Rapid Fire)
