Robotech Defenders Comic Book
(Issue #1, DC Comics)

Keen-eyed Battletech players will notice that a lot of the Robotech Defenders models look like battlemechs from the original Battletech game from FASA. The reason for this is that all of the original edition's 'Mech visuals were based on designs from a variety of anime series, including Macross. Eventually FASA got embroiled in a lawsuit with Harmony Gold and Playmates over the use of the Macross images. As a result FASA dropped all of the derived images (not just the Macross ones) and later editions of Battletech had new visuals for all of the original edition 'Mechs. (On a side note, the Battletech game was originally titled Battledroids, but a lawsuit with Lucasfilm over the use of the term "droid" caused them to change the game's title.)
Since then the successor Battletech license holders have engaged in more legal battles with Harmony Gold over the mech designs with arguments revolving around just what is and is not covered under Harmony Gold's original international distribution deal for the Super Dimension Fortress Macross anime, especially with legal wrangling in Japan over the Macross copyright and ownership between the original production partners.
I won't even begin to try and cover the various legal issues revolving around Macross and Robotech here. For those of you seeking more information, Google is your friend.
