Mobile Suit Gundam Wing: Episode Zero (新機動戦記ガンダムW EPISODE ZERO Shin Kidō Senki Gundam W Episode Zero?), is a manga miniseries based on the anime series Mobile Suit Gundam Wing, featuring stories set mostly before the events of that tale. Unlike other Gundam Wing manga, which are not necessarily considered as being in continuity, Episode Zero has the distinction of being written by Katsuyuki Sumizawa, who was also the writer of the anime series, and thus carries a higher level of credibility. Akira Kanbe handled the art duties for this project.

Episode Zero takes place before the events of Gundam Wing. The manga is separated into stories dealing with each of the five Gundam Pilots and Relena Darlian. Each story takes place at a different point in time before TV series. The stories deal with the early lives of the main characters from the series and reveal how each of the pilots met their respective scientists. The stories go in chronological order for each pilot ending with the launch of Operation Meteor and the beginning of the TV series.


Episode Zero reveals a generous amount of what led the five protagonists of Wing to become Gundam pilots and what occurrences shaped some of the traits they are best known for. It also features notable information on certain other key characters and events that composed the Gundam Wing story.

One of the most prominent tales of the bunch is told within Issues 2 and 3, in which it's discovered that a younger Heero once fought alongside Odin Lowe—the man who, years earlier, had assassinated the real Heero Yuy. A battlefield assault by Heero later on in the tale puts Treize in the hospital, where he would be tended to by Leia Barton—the future mother of his child (who would become the main antagonist of the Endless Waltz story that takes place years later).

The stories involving Trowa Barton and Chang Wufei are, unexpectedly enough, romantic tragedies, as each meet young women who will have significant impacts on their lives. Trowa's story also implies that Catherine Bloom, the circus performer he meets during the series, is in fact his long lost sister who he was separated from during an attack by the Alliance which presumably killed their parents.

The focus is more on origin in the cases of Duo Maxwell and Quatre Raberba Winner. Duo Maxwell is revealed to not be Duo's given name. Instead, "Duo" was bestowed on him by a childhood friend named Solo who was suffering from a dire illness, and "Maxwell" was taken afterwar from a kind priest named Father Maxwell who ran an orphanage along with Sister Helen. Sister Helen and Father Maxwell played a large role in the childhood of Duo, acting in parental roles until they and the entire orphanage were made casualties of an Alliance attack on rebels within the church despite young Duo's best efforts.

Quatre, in contrast, has possibly the least tragic past out of all the pilots. Contrary to what he believes, he is not in fact the product of test-tube reproduction (however, his many sisters are). His mother, Katherine, died in childbirth due to complications from living in space affecting the body's ability to give birth safely. As he refers to himself as a test-tube child in the series, it can be assumed his father and sisters never told him about his mother.

The histories of the two Peacecraft family members, Relena and Zechs Merquise, are unveiled as well. As the Sanc Kingdom fell, only two members of the royal family survived: Zechs and Relena. Relena was adopted by the Darlian family and raised as their own. The story implies that Relena and Zechs met prior to the Gundam Wing series which is how Zechs knew that his little sister was still alive. Also appearing in the story is a young boy who briefly attends Relena's school and resembles Heero.

The manga also features undetailed cameos from notable characters in the series, such as Lucrezia Noin and Sally Po.

Toward the end, the five heroes gather for a brief new mission that's set after Endless Waltz, an event that's anticlimactic but ends with a promising connotation. It all concludes with an affectionate parting message from writer Sumizawa himself to the fans of Gundam Wing.

There is also a bonus chapter titled "Preventer 5" which entails a short, post-Endless Waltz story involving the hostage-taking of Relena and the subsequent intervention of the Gundam pilots (which ends on a cliffhanger of sorts).

  • Episode Zero can technically be considered semi-official, since it was originally going to be included in the Gundam Wing television series. Director Masashi Ikeda specifically asked Sumizawa to pen the main characters' back-stories, and they were to be included in the series following episode 27 ("The Locus of Victory and Defeat"). However, due to production scheduling being the "worst ever" (in Sumizawa's own words) and his withdrawing as a scenarist, Episode Zero's tale kept being delayed and pushed back. Though it was later intended to play some role in episode 31 ("The Glass Kingdom"), the problems persisted, and the Episode Zero story ended up being left out of the anime series entirely.
