Dr. Vega

Dr. Vega; known as Doctor Orihime (ドクター・オリヒメ, Dokutā Orihime)in the Japanese version, is the primary antagonist of the second Star Force game. She was a scientist from the Tanabata Kingdom whose research led to the creation of Matter Waves, materialized EM waves, but she disappeared after discovering Murian ruins.

Her designs for Mu revolve around restoring it and using its power to form the Neo Mu Empire. Those who prove exceptional in some way would be allowed to become a citizen of the new Mu. Her plan required the OOPArt in order to unlock Mu from within the Bermuda Maze (the one involved depends on the version being played). To this end, she recruits Solo, the last living Murian, as well as giving UMA (Unidentified Mystery Animal) wave beings to individuals to carry out her bidding.

After Le Mu (Ra Mu in the Japanese version) is defeated, it is revealed that her primary reason for reviving Mu is so that she could use its power to bring her dead lover Altair (the only person whom she ever formed a BrotherBand with), back to life. Altair, who sometimes referred to her by the pet name of "Vegalita", had to leave her in order to fight in a war. He died fighting in the war, and as a result, Vega became bitter, and ultimately blamed the world for his death, leading her to become a scientist, and after discovering Mu, she vowed to unleashed her vengeance leading to the events in the game.

She had created Hollow as a replacement for her lover, Altair, hoping it would bring him back in a sense, but it had neither his personality or memories, but the image of him kept her from destroying him. Hollow would be her loyal follower, and Vega viewed him as such, until he sacrificed himself for her, making Vega realize that she had loved Hollow as well, not as Altair, but as his own person.

In the anime, she is introduced as a famous researcher who is known for her writings on ancient civilizations as well as the invention of the Radio Composer that Tom Dubius used when he was controlled by Cygnus. She recruited Geo (being able to figure out that he was really Mega Man) into helping her hunt down the OOPArts because she was worried of what would happen should Mu's "Ultimate Lifeform", Le Mu, be awakened. In reality, she wanted to awaken Le Mu and have it rule over the world as its god, eventually revealing this when she had Hollow take the Berserk Sword from Mega Man. In the end, she stayed behind on Mu rather than face imprisonment (as opposed to escaping in the game), leaving her final fate open to interpretation. Her seiyū is Ai Orikasa.

The characters of Vega and Altair are based on the central figures of the Japanese Tanabata star festival
