When Harmony Gold was releasing the first few episodes of its original "Macross" dub in 1984, it was discovered that Revell already had a "Robotech Defenders" line of scale model kits that included the transformable "Macross" mecha. The potential for brand confusion caused concern that Harmony Gold would have problems selling its own transformable "Macross" toys. Harmony Gold and Revell were able to come to a co-licensing agreement — when producer Carl Macek had the idea to combine "Macross" with "Southern Cross" and "Mospeada" to create an 85-episode television series, he chose to use Revell's pre-existing "Robotech" name and logo to strengthen the title's brand recognition.
