It was first seen when Yung introduced the Mirage System and was then combined with Mirage Armaldo and Mirage Kabutops into a Mirage Aggron. Mirage Master then called Omastar to get rid of Ash, Misty, Brock, May and Max, but was unable to follow them outside the castle. It was later destroyed.
None of Mirage Omastar's moves are known.
