Rottweil Berzinsky

Rottweil Berzinsky is the Master of Archer of Red of the Red Faction in the Great Holy Grail War. Along with Cabik Pentel, Deimlet Pentel, Jean Rum, and Feend vor Sembren, he is entranced by Assassin of Red and Shirou Kotomine before even meeting his Servant, later coerced into giving up his Command Spells. Rottweil appears to specialize in body modification as almost all his vital spots besides his face are covered with silver lizard scales. (Source: TYPE-MOON Wiki)
