Geperunitch spends most of time—from his initial appearance in episode 1 of Macross 7 —acting through the human body of U.N. Spacy fleet advisor Ivano Günter. Geperunitch's human form is somewhat feminine, with a slim figure, long blonde hair, a high-pitched voice, and lips which appear as though they have dark lipstick applied. Consequently, he has been mistaken for a woman by fans in North America and Europe. However, as clearly evidenced at several points in the series, Geperunitch's human form, Ivano Günter, is male. A version of Macross 7 that has appeared in North America with English subtitles stresses the fact that Geperunitch is male in episode 3 to avoid confusion.
