Robotech

Robotech is an 85-episode science fiction anime adaptation produced by Harmony Gold USA in association with Tatsunoko Production Co., Ltd. and first released in the United States. It was adapted from three original Japanese television series.
In the series, Robotechnology refers to the scientific advances discovered in an alien starship that crashed on a South Pacific island.[2] With this technology, Earth developed robotic technologies, such as transformable mecha, to fight three successive extraterrestrial invasions.Robotech is a story adapted with edited content and revised dialogue from the animation of three different mecha anime series:
-The Super Dimension Fortress Macross
-Super Dimension Cavalry Southern Cross
-Genesis Climber MOSPEADA.
Harmony Gold's cited reasoning for combining these unrelated series was its decision to market Macross for American weekday syndication television, which required a minimum of 65 episodes at the time (thirteen weeks at five episodes per week). Macross and the two other series each had fewer episodes than required, since they originally aired in Japan as weekly series. On some television stations, the syndicated run was preceded by the broadcast premiere of Codename: Robotech, a feature-length pilot.
