Information
Reappearing after Ripper's death in XBlaze – Code: Embryo, Brain Cat demonstrated the ability to talk. He seems to recognize Tōya Kagari. He became sentient because Ripper's spirit inhabited him.

This particular Brain Cat is one of a series of dolls that are particularly popular overseas from Japan.

Appearance
Brain Cat appears as a small cat-like doll with white fur that stands perfectly upright. His head is seemingly protected by a yellow helmet with an ornamental design on the top; it perfectly covers his pointy ears. Brain Cat wears an orange suit that covers most of his body; it has a white collar and a large black bow on the front. Prodding out of the back of his orange shorts is his white tail, which is splashed with black on the triangular tip. His paws are the most cat-like feature about him as his feet are merely ovals with a yellow capping that matches his helmet. Brain Cat has a small, toothy smile and beady red eyes that rest in black sockets.
