The Top Ten
1 Sheen Sheen Juarerra Estevez is a main character from The Adventures of Jimmy Neutron: Boy Genius and also the protagonist of his own series, Planet Sheen.

He is my second favorite Jimmy Neutron character. I love this show!

2 Carl

Carl is so funny, but I don't like his obsession with Jimmy's mom.

I just love Carl! He is the best character in the whole show. He is so funny.

3 Cindy

Definitely a favorite. Cindy has an amazing personality and loves martial arts. She has that girly side to her (Cindy's bedroom is proof of that). The adorable outfit she wears, along with her way of hiding her real feelings, makes Cindy one of the all-time favorite characters. She's right up there with Helga from 'Hey Arnold!' and Angelica from 'Rugrats'. These three girls have become important and famous among Cartoon Network fans.

She's the most beautiful character ever throughout the history of Nickelodeon.

She's the only lovely character on the show. The other characters are annoying.

4 Jimmy James "Jimmy" Isaac Neutron is a fictional character and the main protagonist of the Jimmy Neutron franchise . He is most notably the main protagonist of the 2001 American 3D computer-animated comic science fiction film Jimmy Neutron: Boy Genius and the main protagonist of the American computer animated... read more

He's an adorkable science genius. He's hilarious and awesome, even 10 years after the show ended. I bet he's inspired many kids to become brilliant scientists and engineers.

Jimmy Neutron is one of my favorite characters.

I feel bad for Jimmy because Cindy is always making bad jokes about him. It's so annoying.

5 Hugh Neutron

Sometimes he's clever, and sometimes a little stupid too, especially when it comes to tiny situations.

6 Paul
7 Bolbi
8 Professor Calamitous Professor Finbarr Calamitous (simply known as Professor Calamitous) is a fictional character and the main antagonist of The Adventures of Jimmy Neutron: Boy Genius.
9 Libby

Libby deserves way more credit than she gets. She is beautiful, brave, and funky. She's way more than just Cindy's best friend. Her and Sheen are very cute together.

Sassy, but not straight-up cruel like Cindy.

10 Mrs. Fowl
The Contenders
11 Goddard
12 Betty Quinlan

She looks a lot like Miranda Cosgrove.

13 Beautiful Gorgeous Beautiful Gorgeous is a fictional character and the daughter of Professor Finbarr Calamitous from the American animated series The Adventures of Jimmy Neutron: Boy Genius created by John A. Davis for Nickelodeon.
14 Judy Neutron
15 Brittany Tenelli
16 April the Gorlock

She's cool and kinda looks like a Bratz doll!

17 Ultra Lord

You guys have got to be kidding me. If it wasn't for Ultra Lord, Sheen wouldn't even be in the show. Instead of rebooting 'Jimmy Neutron', we should get an Ultra Lord movie.

Come on guys, this guy needs to be number one.

Best character in the whole show!

18 King Goobot V
19 Nick Dean
20 Elke Elkberg
21 Annabelle Neutron
22 Skeet

Dude, you're supposed to push the buttons with pictures of food on them.

23 Kari Neutron
24 Evil Jimmy Neutron
25 Cap'n Betty
