As a captain within the Galactic Republic during the third Galactic War, Meinar was a Human male. Back in 3626 BBY, he was a member of the Republic Guard.
Meinar is a boss character in the video game Star Wars: The Old Republic, specifically within the Onslaught expansion pack. He is only featured in the Imperial narrative; Ziliss fills his role in the Republic version of the story.
In the Imperial story, Meinar, along with Republic soldiers Corrik and Osonu, encounters the Commander, Darth Krovos, and Darth Rivix. This confrontation occurs when the Imperials arrive at the Dantooine Jedi Enclave to find out where Darth Malgus is. Eventually, Meinar becomes the sole survivor of his team, his comrades having been killed. With Rivix holding him captive, the Commander takes Meinar's holocommunicator to contact Jedi Master Leeha Narezz. Narezz refuses to reveal her mission's details and ends the call, leaving Meinar to Rivix's decision. The Commander then has the option to command Rivix to either kill or let Meinar live, or to remain silent about his destiny. If the option aligned with the light side is selected, Rivix will seemingly kill Meinar by accident.
