Ratte-44

After KV-44M was hit by big bertha's bullet, his body was annihalated and his head was only the thing left. Black ratte was also critically damaged. So the twilight mechanical engineer thought of a way to make a iron monster to defend the Soviet Fortress. He told Stalin that he had to take the head of KV-44M and the body of Black Ratte in order to create Ratte 44, so Stalin called Soviet Ratte to accompany him to complete this mission. So they removed Black Ratte's head and replaced it with a KV-44M's head and then replaced Black Ratte's broken guns with KV-44 remaing guns. At the end of the episode of its creation, it looked normal until its eyes glow red. It is unknown if it is still in beserk mode or either haves Black Ratte's data base (this is because both eyes are specifically red).
