Bayer

Long dark hair spills well past Bayer's shoulders, paired with pale eyes and slender brows. He outfits himself elaborately: a white Breton cap stamped with a Q and trimmed by a dark brim, a covering over his nose and mouth, and a double-breasted suit whose cape fastens at the ends to his cuffs. A dark button-down sits beneath the jacket, finished with a pale tie, a belt at the waist, dark trousers, and dark boots.

Bayer starts out seeming respectful, going so far as to applaud Satoru Gojo for deflecting his attack. That poise breaks down quickly, though, and anger takes him without much provocation, as it did the instant Gojo proposed that he surrender.

Bayer was sent together with Kokun to the location holding Riko Amanai, the vessel slated to merge with Tengen. Kokun went in to deal with Riko while Bayer stood guard outside. Upon the arrival of Geto and Gojo, Bayer faced off with Gojo as Kokun handled Geto. Gojo gave him the chance to give up, which only stoked his fury, and the ensuing fight ended fast with Bayer thoroughly outmatched. His loss triggered the breakup of Q, and what became of him afterward was never confirmed.

Little is documented about his true abilities beyond his billing as Q's strongest fighter. He was shown throwing several daggers in combat. Supplementary material states that his codename derives from a Japanese sausage brand, and there is a chance that, once Gojo and Geto had taken him prisoner, he was put to death.
