Robotech

One of the first Anime to be released in the United States, Robotech wasn't technically made in Japan. Robotech fused the story lines of three different Japanese Anime series (with some modifications): Macross, Mospeada, and Southern Cross. The reasoning for combining these unrelated series was that the American TV stations had a minimum number of episodes requirement, and none of the three series met that requirement alone.
