Aston's pretty quiet—he's not one to say much. He's undergone the Alaya-Vijnana surgery, a procedure that happened back when he was classified as Human Debris. That experience shaped a lot of what he became.
He spent his time piloting mobile suits under Kudal Cadel, working with the Brewers space pirates until things fell apart. When Tekkadan took down Brewers, Orga saw an opportunity and extended an offer to the surviving Human Debris, including Aston. He took it, trading one outfit for another.
