In the distant future, in a distant corner of Siberia, people live in domed cities called Domepolises. These are the primary human living spaces on Earth, which became uninhabitable years ago from environmental destruction. Now, parts of the Earth are becoming habitable again. Large portions of the Domepolises are breaking off to escape the powers that control the domes and trade. Gainer Sanga, video game champ on his 200th victory, becomes an unwilling helper in his hometown`s Exodus when he is wrongfully arrested by the Siberian Railway. He pilots a giant mecha which he dubs `King Gainer` after his own video game handle. He is challenged to fight other Overmen as Yapan tries to escape across Siberia. - The manga is an adaption of the anime that goes by the same name and which was thought up and directed by Yoshiyuki Tomino. The manga is drawn by one of the series' character designers, Yoshihiro Nakamura, and Tomino is credited as writer. Nakamura is (in my opinion) a rather talented artist, with a good sense for scenery and setting. He has a knack for adapting the great designs originally done by Kenichi Yoshida and manages to bring these characters alive. Taken from Gainer and anidb

According to Sumisawa (author), the events of Episode Zero were supposed to appear in the TV series, just after episode 27.

After the war that took place in A.C. 195, each of the protagonists have gone on with their lives, and the gundams put into retirement. As the peace alliance with the colonies push through, a new menace threatens to shatter the peace, and the five gundam pilots are forced into action once again. Blind Target is originally a radio drama that got translated into manga. It is one of the possible events that took place between the series itself and the OVA, Endless Waltz. Other manga titles that also delve into the possible events between the series and the OVA are Battlefield of Pacifists and Ground Zero. All three remain unrelated to one another.

Heero attempts to live a normal life after the war. But his "peaceful" life is disturbed when someone manages to steal Wing ZERO. He rushes to search for it, and is then faced with an unlikely foe. On all accounts, Ground Zero can be considered a doujinshi due to its lack of consistency and subjected humor. However, it tackles deeply into the characters' morale and philosophies regarding war, peace, and of course, the gundams. Like Battlefield of Pacifists and Blind Target, Ground Zero are *possible* events that take place in between the TV series and the OVA, Endless Waltz.

Taking command of the terrorists, Lelouch adopts the alias "Zero" and begins his rebellion to crush Britannia once and for all. However, his greatest friend soon becomes one of his most troubling enemies when Suzaku becomes the pilot of Britannia's new test model Knightmare, the Lancelot.
