Carl Wheezer

Carlton Ulysses Wheezer is a bespectacled dim-witted boy and one of Jimmy's best friends. He is one of the main characters of the Jimmy Neutron franchise. He is also the deuteragonist of its prequel movie Jimmy Neutron: Boy Genius. He is Jimmy's neurotic, llama-loving, best friend. Carl and his parents have numerous allergies, at times even to things that are incapable of triggering allergic reactions. He passionately loves llamas, and his passion for them is often used as a running gag throughout the series. He is also known for his bizarre obsession with Jimmy's mom.

Why He Rocks

 * 1) He’s just as likable and unforgettable as his best friend, Sheen Estevez, who is also a comic-relief character.
 * 2) Despite his doubts and insecurities, he tries to look on the bright side of problems at times, like comforting Jimmy in those situations for example.
 * 3) He has many memorable catchphrases and lines of dialogue, such as “Ow, my scapula!”, “STOP IT, STOP IT! CAN'T YOU SEE YOUR CONSTANT FIGHTING IS TEARING US ALL APART?!” or “But Jimmy, I'm allergic to infrared!”.
 * 4) He is very loyal to his friends and family, much like Jimmy and Carl, and is always there for them.
 * 5) * With this in mind, despite his massive insecurities and goofiness, he can be very competent and helpful towards his friends when push comes to shove or in general.
 * 6) * Like Jimmy from Ed, Edd, N Eddy: He is a nice and innocently cute child, and one of the purest characters. Who is also friendly towards anyone.
 * 7) His love for llamas is very charming and iconic.
 * 8) Robert Paulsen does an amazing job at portraying/voicing the character.
 * 9) He has a good character design.
 * 10) He is extremely hilarious and also has many hilarious moments, like. Mostly because of moments with his goofiness, but he can also be the result of his eccentricities.
 * 11) * And a bit like Patrick Star or Billy: He may be dumb, but he presented his idiocy hilariously.
 * 12) Just like Shaggy: His cowardly demeanor can really get a great amount of laughs out of the viewers, which is one of the most memorable things about the 'Jimmy Neutron' franchise.
 * 13) Because of this, he sometimes steals the show with his comical behavior or his failed attempts at fawning over Judy Neutron (Jimmy's mom) to be his love interest, which comes off as insanely hilarious.

Bad Qualities

 * 1) His hilariously bizarre crush on Mrs. Judy can get marginally creepy, especially this scene.
 * 2) He was unlikable and completely out-of-character in the episode "Carl Wheezer, Boy Genius", where he acted like a stuck-up, egotistical genius since he wanted to be like Jimmy to win a crush his age, as he never apologized to Jimmy for his mean-spirited behavior.

Trivia

 * He was by far, the most memetic character in the show aside from other characters such as Hugh Neutron or Jimmy himself for example.
