Rottweil Berzinsky

Rottweil appears to specialize in body modification, as nearly all of its vital points, except its face, are covered in silver lizard scales. This made its body quite durable, as it was able to survive a massive explosion from a faulty Holy Grail by molting. It also inherited reptilian mannerisms, preferring dark and damp places.

He and the other Masters of the Red Faction , with the exception of Kairi, gather in Sighisoara . There, they discuss the situation of the Great Holy Grail War , and Feend vor Sembren questions their involvement in the sub-war. Feend reminds Rottweil of his contract and that attacking allies is forbidden. Shirou Kotomine enters the room and provides the location for the summoning ritual. Rottweil is easily bewitched by the Red Faction's Assassin poison upon his arrival.

He's obsessed with animals, particularly lizards. He likes dark, damp places.

Rottweil gives the impression of having a very treacherous nature where, in a subspecies of Holy Grail War, he killed both his client and his companions because of the way the nature of the war " irritated " him, along with the fact that it was not written in the work contract that he could not kill the contractor.

Rottweil is a red-haired man who wears retro tinted glasses. Aside from his face, most of his body is covered in silver scales. He also appears to have the organs of a lizard.

Rottweil is an independent sorcerer . Like other Masters of the "Red" such as Jean Rum and the Pentel brothers , he has fought alongside and against Kairi Sisigou on several occasions.

He once participated in a Holy Grail War Sub-War , which has a maximum of five Servants . The organizer stated that the objective of this war was to gather magical energy . His client hired him to participate in the summoning ritual and kill their respective Servants . Rottweil became irritated by this task, so instead he killed his client and the other participant. However, the gathered magical energy was unleashed, causing a massive explosion from which he barely survived, having to shed his skin twice to recover.
