Biotic/Sentinel tank, specializing in defending and restoring his comrades.
The Guardian was an elite Alliance soldier, deployed when a dangerous situation required the best and brightest. A master of defensive tactics, he became popular among his squadmates. Over the years, he and the Commando became close, although duty required they keep their personal relationship hidden from their comrades. The Andromeda Initiative struck them as a perfect way to serve while living as partners -- on and off the field.
