Sheen Estevez

Ramon Juarrera "Sheen" Estevez (born November 16th, 1989) is one of the three deuteragonists (alongside Goddard and Carl Wheezer) of the franchise, and the titular main protagonist of its spin-off Planet Sheen. He is one of Jimmy's best friends.
He is voiced by , who also voiced Pip in the Barnyard franchise.
==Personality==
Throughout the whole series, Sheen is a extremely hyperactive kid with a highly raspy voice and a wacky personality, he has shown to be eccentric, loony, insane, energetic, high-spirited, brash, arrogant, insensitive, self-absorbed, overdramatic, hammy, and a geeky person with a mischievous and loud-mouthed streak, Sheen also has a bit of an ego like Jimmy does and can be seen as a bad friend at times. These are traits that are generally played for comedic relief. 
Despite being pretty scatterbrained, a very incompetent slacker in school, often yelling all the time, a bit of a masochist and rather stupid to a fault, Sheen cares about Libby more than Ultra Lord since he was more than willing to fight Yoo-Yee to get her back one time, happens to be quite supportive and loyal to his friends, has encyclopedic knowledge of Ultra Lord (to the point he wrote the entire Ultra Lord website), and was tough enough to wrestle an entire wild grizzly bear without a scratch on him. 
Sheen's obsession with Ultra Lord is one of the many running gags in the series. He is shown to have many Ultra Lord action figures, knows a lot of the trivia from the show, and wears an Ultra Lord t-shirt. His love for the superhero was noted in the original film, and was carried on throughout the course of the series. His love for Ultra Lord constantly annoys everyone with his ramblings about Ultra Lord. Despite this, Jimmy and Carl still consider him to be a good friend.
In the movie, he was fairly intelligent and more comedic than hyperactive. In Season 3 of Jimmy Neutron, Sheen has become a lot more loud, hyper, ignorant and prone to over-the-top outbursts than before. In the series of Planet Sheen, all of his serious and smart traits have been totally erased; changing him from being nerdy and hyperactive into becoming an really obnoxious, selfish and reckless idiot.
===Jimmy Neutron===
Sheen is Jimmy's second-best friend after Carl (who is also comic relief).
He is a big Ultra Lord fan. Even so to be obsessed with it. Sheen is Jimmy and Carl’s best friend, and Libby’s boyfriend. Although Libby didn’t like Sheen, they became a couple at the end.
However in Planet Sheen, his new girlfriend is Aseefa.
=== Planet Sheen ===
In Planet Sheen, he was the main protagonist of it. In the first 18 episodes of the UK Version of Planet Sheen, he has his blank flank. In the last 8 episodes, Sheen got a new shirt. In the USA's first episode, he has his blank flank. But in the last 25 episodes, he got his blank flank.
==Trivia ==
*Sheen is 11 years old.
*Sheen is of Mexican descent.
*Sheen's name (or nickname, though it gets used as his main name) and family name derive from the family of actor Martin Sheen, born Ramón Antonio Gerardo Estévez. There is arguably a resemblance between Sheen's basic design and Martin's sons, actors Charlie Sheen and Emilio Estevez.
*Sheen's talking primate companion, Nesmith, is named for musician and video artist Michael Nesmith, a member of the 1960's band, The Monkees.
*He turned into a Planet Hero when he accidentally flew into Space.
*He (Amy), Libby (unnamed brother) and Jimmy (Brobot) are the only major characters who have siblings.
*In "Who Framed Jimmy?", Sheen mentions he's taken bear-wrestling classes.
*Considering Sheen has a new girlfriend in his titular show and he always had a thing for Libby, it could be implied or interpreted that Planet Sheen is considered non-canon, as none of the characters acknowledge the events.
*Many consider Sheen to bear a resemblance to another iconic Nickelodeon character, Fanboy from Fanboy & Chum Chum.
