The First Robotech War begins when giant warriors called Zentraedi arrive to retrieve a crashed alien starship containing Protoculture energy.

The Third Robotech War occurs after spores of the Flower of Life plant attract the Invid who rapidly conquer the planet during this final conflict.
Harmony Gold lacked funds to complete the series alone because the Yen/US dollar exchange rate dropped from 250-1 to 160-1 by the end of 1986. This currency shift caused toy partner Matchbox to withdraw from producing the series leading production to cease after only three episodes were made.
Palladium Books released role-playing games covering the storyline starting in 1986 before going out of print in June 2001.
