A Mecha from the Macross series. It first appeared in the Macross Zero OVA from 2002.
The ADR-03-Mk III Cheyenne I Destroid was one of the first defense robot systems (mecha) created by the U.N. Spacy to fight the Zentradi after the fall of the SDF-1 Macross on Earth. It is very similar to the Tomahawk (Destroid) from Choujikuu Yousai Macross.
The Cheyenne I was designed by Ishigaki Jun'Ya.
