Gundam Wing

Gundam Wing is an anime created by Sunrise studios. The series centers around the struugle of Earth's future colonies for independance, and its primary characters are five boys who have, by various means and for various reasons, been recruited by the colonies to pilote the giant Gundam mobile suits (basically giant robots. Kind of like the MegaZords in Power Rangers, but less plastic-y). These characters face the the horrors of war head on, and the series deals with not only the conflict itself but its impact on its main characters.

Characters

 * Heero Yuy (often abreviated in fanfiction as 1). Heero took his name from the martyred leader of colonies. His real name is never mentioned in the series, nor is much of his past revealed. Heero often appears cold and emotionless, but is in reality quite a caring individual who simply prefers to keep his emotions private.
 * Duo Maxwell (often abreviated as 2). Duo grew up as a homeless child on the streets L2 (one of the five colonies, the other being L1, and L3-L5), and became second in command to his gang leader Solo (who gave Duo his first name). When Solo died, Duo was adopted by the Maxwell Church, from which he took his last name. Upon the ransacking and subsequent burning of the church, Duo ran away and was recruited to fight for the colonies. He is cheerful despite his traumatic past, and one of the only outward signs of his past is his descision to call himself the God of Death, in reference to a conversation he once had with a sister of the Maxwell Church.
 * Trowa Barton (often abreviated as 3). Trowa grew up as the mercenary soldier No-Name. When the mercenary company which raised him was killed -- mostly by Trowa, who believed them to be spies -- he set off to find a home and place to stay. He joined the Barton Foundation, a group which makes weapons, and eventually, when the actual Trowa Barton was killed, No-Name took his name. Due to his past history, Trowa is stoic and unwilling to show any kind of emotion. However, he truly does care about others, and has been known to put himself in danger to save others.
 * Quatre Raberba Winner (often abreviated as 4). Quatre grew up wealthy as the youngest (and only) son in a family of thirty children. He is also the only natural-born child, though he does not know this fact. His family owns the Winner Corporation, a mining company, and they are firmly dedicated to non-violence. When Quatre ran away from home at sixteen, he met the Maganac Corps, a group of Middle-Eastern fighters. Quatre earned their respect, and later came to lead the group. He later chose to pilote a mobile suit to protect the colonies, going against his family's non-violent principles. Quatre is warm-hearted and open, often appearing to be the most childish of the group. Because of his priviledged upbringing, he can sometimes come accross as ignorant of certain things, but he truly cares about his family and his comrades.
 * Wufei Chang (often abreviated as 5). Wufei grew up in a relatively well-off family, allowing him to devote himself to learning and thinking. At sixteen, he was married to Meilan through an arganged mariage, and initially disliked her and disdained her propensity towards violence. However, when she took it upon herself to protect the colony and died in the attempt, he came to admire her courage and vowed to carry out justice in her name. Wufei is reserved and looks down on those he deems weak in body or spirit. Initially, this causes him to disdain working with others, though he later comes to accept that he must in order to bring about the justice he so craves.

In fanfiction
The Gundom fandom is moderately popular, especially among slash fans. Because all of the main characters are young, relatively attractive men, fanwriters often pick their two (or three) favorites and thrust them together. The most popular parings are HeeroxDuo (often abreviated 1x2) and TrowaxQuatre (3x4), with Wufei thrown in as the token straight man of the group. This can be well done, just as any pairing can be well done, but it is a sad reality that much of it is not.

A widely read slash goodfic has been written by Sunhawk16, and is hosted on LiveJournal. The Ion Arc features the usual slash pairings (1x2 and 3x4), and has been recently completed. (Quick warning: the finished work is over one million words long; reading in a single sitting is not recommended. Also, some parts may be NSFW, due to details of a midly graphic nature.)
