Sheen Juarrera "Loco" Estevez is one of Jimmy's best friends in Jimmy Neutron: Boy Genius and the main character of the series Planet Sheen.


Sheen isn't the brightest person in the world. Sheen is obsessed with the Ultra Lord action hero. He collects all the Ultra Lord action figures, cards, and quotes him daily. Sheen is 13 years old (he got held back a few times.)



Main article: Sheen and Libby Relationship

Sheen's romantic interest is Libby and his interest in her became highly noticeable towards the end of the first season of the series. When Sheen had a crush on LibbyYoo-Yee took advantage of this in Crouching Jimmy, Hidden Sheen by taking her captive and ordering Sheen to duel him for her freedom.  At the end of that same episode, Libby called herself his girlfriend, giving him the Eye of the Tiger and the strength to fight back, successfully ensuring Libby's safety.


In Planet Sheen, he has a new romantic interest: A blue alien named Aseefa. However, it is unknown whether it's just a crush or Sheen actually has a relationship with her.

Planet Sheen

Sheen is a turbocharged, hyperactive child with an attention span of 0.4 seconds. His best friend back home is a boy genius Jimmy Neutron. He's got a passion for life, TV, guacamole, and a superhero called Ultra Lord. He isn't the best student, but what he lacks in common sense and focus, he makes up for it by displaying curiosity and loads of energy. One day, disobeying Jimmy's specific instructions ("Sheen, Do Not Touch This Rocket!"), Sheen touches a rocket and goes flying into deep space. He lands on a strange planet called Zeenu, where the grand leader thinks that Sheen is destined to bring peace, prosperity, and eternal joy. After the Emperor promotes Sheen to be his number one Royal Advisor, Sheen gets to do virtually whatever he likes, such as battling man-eating creatures and throwing wild parties. Even when the villain Dorkus tries to destroy him, Sheen's crazy ways almost always save the day. On the end of a few early episodes of Planet Sheen, Sheen writes a message to his grandmother in his starlog. All of the messages make no sense, but they sum up everything that happened in the following episode. He doesn't seem at all worried about whether he'll get back to Earth or not. However, since his future self has been seen in "The Tomorrow Boys", it can be implied that Sheen eventually made it back to Earth. Though it is possible that even though the evil dictator future is gone, the future they thought they were heading doesn't exist and so it is possible that Sheen made a new future by himself on Zeenu and will not get back to Earth.

According to Carl Wheezer's podcast takeover on "Talkin' Toons Podcast" by Rob Paulsen, Sheen has come back to earth, but he is now in a juvenile detention center. However, all three of them are still friends.


He is sometimes called the Chosen One, Ultrason by his dad in the movie, and Ultradork by Nick or Cindy. He can also be called Annoying Doofus by Carl (Only in "Sheen's Brain").


In "Operation: Rescue Jet Fusion", Sheen states that he is Mexican, although it has been inferred before.


In The Adventures of Jimmy Neutron: Boy Genius, Sheen has peach skin. He wears a turquoise Ultra Lord T shirt and black pants. He has short black hair that is usually spiked and is usually shown wearing a pair of turquoise-and-white hi-top Converse All-Stars and always wears a pair of red or purple Ultra Lord underwear.

Despite being related to the man who invented spray-on eyebrows (as stated in Beach Party Mummy), Sheen has no eyebrows, nor a chin.

In Planet Sheen, Sheen doesn't wear his trademark Ultra Lord t-shirt. (Although he did wear his normal clothes throughout the first episode.) Instead, he wears a sea green jacket (with a Zeenu insignia on his right chest), blue pants, blue boots, and a black belt with a silver buckle.

Eye Color

Sheen's eyes are normally brown but in some episodes, there are mistakes. For example, in The Fairly OddParents special, his eyes turn indigo, and in the next non-crossover episode, his eyes are black.

While Yoo-Yee is a Jimmy Neutron villain, he's more of Sheen's enemy than Jimmy's. The reason is in Crouching Jimmy, Hidden Sheen, during a dance at Lindbergh Elementary School one night, some ninjas kidnap Libby, the love of Sheen's life on orders of Yoo-Yee himself! Moreover, the reason he commanded Libby's abduction is to lure Sheen into a battle just because the former wants to replace the latter as the Shangri-Llama Chosen One. Obviously, anyone who messes with Sheen's darling female friendYoo-Yee included, really gets on Sheen's bad side much more than those who make fun of Ultra Lord. This is because Ultra Lord is fictional, but in Jimmy's universe, Libby is real.
