MooMooFarm - Uh... Macross: Do You Remember Love (the movie) pulled it off in 1984, about twenty years before Gundam SEED showed up to have Mwu do the same thing. You may want to get your continuity right before claiming Show X was ripped off by Macross.
Besides, how does this differ from the fights in Gundam SEED Destiny or 00, where the recycling was even more blatant?
