An Orguss shows up in Macross (DYRL I think) for about 1.5 seconds. Basiclally it's standing on the SDF-1 firing at Zentradi likke you're standard destroid. It's shield is on the wrong arm, which prompted a joke that it must have been reveresed when it crossed over to our dimension.
Lots of Macross folks worked on Orguss so it was probably an inside joke, like the pepsi and budweiser cans hidden in the missle swarms.
