Intro. Serrat is the largest Wintherin shown on the screen among those in the Sentinels volume. It has noticeably higher muscle mass compared to other specimens.
Serrat, who was severely beaten in battle, almost until death, before he was saved by the killer and rebuilt, is biomechanical. Serrat has been equipped with an improved or replaced front limbs, wings and a helmet, which seems to be permanently attached to the skull, repairing damage caused before the assassin's involvement. Despite this, Serrat seems to have one eye, not two, because one side of the helmet is damaged and there is no shining light visible on the other side.
Serrat wings emit electric arches during landing, either because of their nature of plasma projection, or as a mechanism that ensures safe landing. In addition, thanks to the integration of the jet drive, Serrat is able to fly quickly enough to keep up with hellish ships.
