Macross is an Anime Japanese serie created in 1982, featuring a fictional history where humans reverse engineer an alien star ship crashed in an island, allowing them to create transformable mechas amongst other advances.
The series was later adapted in the U.S. (mixing other anime series too) into the also popular Robotech franchise.
The original release in 1982 was entitled Super Dimension Fortress Macross, later there would be prequels, sequels and side stories in which we could highlight (because they got 1/72 scale models) Macross Zero, Macross Delta, Macross Frontier and more. Note they are not cited in chronological order, either of appearance either of the events.
