Top 10 Jimmy Neutron Villains
The Adventures of Jimmy Neutron may not be known for its villains, but for the ones that do have done things to try an eliminate The Boy genius in their attempts. They may come close, but they seem to have made their mark that's for sure.
Who is more fitting to be at the top of the list than Goobot, who was the villain in the very first film that got the pitch for the series going? He kidnaps all the parents around Earth and creates a giant alien chicken. He tries many different ways to get revenge on Jimmy since their first encounter.
If Patrick Stewart had kept voicing the character, that would have been something. Otherwise, he is the most memorable villain in the series.

He might be one of the most recognized villains in the entire series. Voiced by Tim Curry, he is a fallen scientist who forgets things very easily, which is always hinted at throughout the series. Whether in disguise or up front about his evil plans, Finbarr is indeed a worthy challenger to Jimmy at times.
One thing that remains unanswered is who his wife is. That's never been answered in the series.

In his first appearance, Evil Jimmy is seen doing chores for Jimmy. He starts as a comedy gag but turns evil at the end of the episode. Nothing happens to him, and we have no idea how he escaped.
In The Trouble with Clones, he really takes the cake. Temporarily controlling others with Jimmy's hypo-ray and creating his own world in Jimmy's lab makes him one of the most dangerous villains. Jimmy is forced to fly to that dark duplicate side of Earth where everyone is downright evil.
Eventually, Jimmy finds Evil Jimmy. He nearly saves the Earth but just barely. The clone destroys the chip, creating a dark matter dimension to trap Jimmy for good. Creating a bad side of your clone and equally knowing your own creation can be quite the formidable opponent.

If Goosebumps didn't remind many why they fear puppets, then Flippy might just top that even more. Coming back to life thanks to a chip that sucks up Hugh's brain is a pretty creepy concept. To the point he is just terrorizing Jimmy. Finally, he gets Carl and Sheen to help stop this mad puppet from doing some serious damage.
At the end of the episode, he is seen as if he is still alive despite frying the chip. How unsettling is that cliffhanger to this day?

What makes Meldar so menacing is how much power (matrix generators) he controls. Right away, he only cares about ratings and making others miserable. He is voiced by Tim Allen, which is cool. To his shock, the humans win and get out alive with their planet intact.
Jimmy turns back to save all the other species. After generating back after being hit by a stage set background, Jimmy and April formulate a plan to get the generator off of Meldar. They manage to do so thanks to Carl's way with a Flargi (I can't think of the other name in the episodes).
Everyone is set, and Meldar is left with an electric shock for the rest of his life.

There are times she is a very wise and cunning villain who can go toe-to-toe with the likes of Jet Fusion. She uses her manipulation on others when nobody else is in the way.
When she returned once again, she would have had her way if it wasn't for Carl and Sheen seeing her get both Jet Fusion and Jimmy to forget what took place with hypnotic gadgets. She comes back one more time, only to have a weird interaction with the Junkman, which is, well, whatever.
This interaction gets rid of a lot of cool parts of the character despite the very generic name picked out.
The Newcomers


An overweight, smelly alien who tries to sell whatever he has with him. In the episode The Junkman Cometh, he is seen making deals with another creature. He had the idea of shipping off humans he called water sacks. That fails, and he returns in the finale where he interacts with another villain.
Well, when you have a ship that uses a tractor beam to lure up junk and enemies, that's worthy of being here, isn't it?

Deep down behind that smile, she's really an alien. In her debut episode near the end of season 3, Taters controls the entire town of Retroville against their will to force them to watch her show. She nearly succeeds.
What makes her stand out is the disturbing close-up of her sinister eyes at the end of the episode. She says, We'll be back, once she is defeated. In the series finale, the League of Villains doesn't take her seriously until she brings up an option to wipe out Neutron when they capture him.
The way she goes from goody-goody to suddenly methodical earns her a spot over others.

These three space bandits have been in many different episodes of the show, whether as recurring villains or turned good. At one point, they are found in a season episode, found again deep in space finding a new vehicle from Men At Work. They sell all the people of Retroville for merchandise. They have tried many different ways of eliminating the humans but have failed each time, eventually giving in during the series finale.

This robot is set from the future. He sees intruders not wearing the same uniforms as the rest in the tyranny ruled by Libby. The boys then discover their older selves. The Copbot pursues them by going to the present time. He nearly had them cornered only for the megalomanium to explode, causing the bot to shoot it.
