== Synopsis ==
The backstory of ''Zero Wing'' varies between each version,<ref name="ZWSMDmanual"/><ref name="ZWPCECDROMm"/><ref name="ZWhg101"/><ref name="ZWss"/> but the plot within the game itself remains consistent. Set in 2101, the game follows the signing of a peace treaty between the [[United Nations]] (also translated as the [[Milky Way]] Federation) and CATS, a [[space pirate]] organization, who later breaks the covenant and takes control of the Japanese/Federation space colonies. The protagonist Trent leads a ZIG space craft, which had managed to escape from a mothership destroyed by CATS' representative, with the aim to defeat enemy forces, avenge the mothership and its crew and liberate the Earth. On the PC Engine version however, the story is different. CATS are replaced with an organization called Abigor led by a man named Ludwig and his right-hand woman Seiren. Abigor attack the Galactic Federation and the ZIG, piloted by Masato Tachibana, is send to repel them before it is eventually revealed the Federation dispatcher's sister Airen, who had worked as an undercover spy alerting the Federation of Abigor's attack, is arrested by Seiren who turns her in to Ludwig. After Ludwig chooses to spare Airen's life, Tachibana then ends up getting into communication with Ludwig who challenges him to a battle with a condition to give Airen back if Tachibana wins. Tachibana accepts and blows up Ludwig's ship, Ludwig giving up Airen before committing suicide. Airen and Tachibana then celebrate their victory before returning to Earth offscreen.
