UFO Robot Grendizer tai Great Mazinger

UFO Robot Grendizer tai Great Mazinger (UFOロボ グレンダイザー対グレートマジンガー) is a 1976 animated short film that crosses over Go Nagai's super robots Grendizer and Great Mazinger. The movie features alternate versions of events from both series, and, as with the rest of the Vs. films, is not canonical to either one. The film was released in almost all countries where the original Grendizer and Great Mazinger series were also shown, most prominently in Italy, France and the Middle East.

Story
In an effort to destroy Grendizer once and for all, the Vega Empire has captured Duke Fleed's closest ally, Koji Kabuto. While under a mind control in captivity, Koji reveals the history and location of both Mazinger Z and Great Mazinger. The Vega Empire seized the opportunity to capture the Great Mazinger and forcing Duke and his Grendizer to do battle against the formidable Great Mazinger. Grendizer and Great Mazinger clash in battle until Grendizer manages to deactivate Great Mazinger using a panel on its back.

Also starring in this movie are three exclusive saucer beasts named Jinjin, Gubigubi, and Koakoa that also battle Grendizer only to be easily defeated.
