Prototype Red-B, known as Prototype Ai-B in the Japanese version, is a character appearing in the Yu-Gi-Oh! VRAINS anime. It is a prototype Dueling AI that was designed by Kitamura, who uses it to defend SOL Technologies' Data Bank.



Red-B is visually represented as a vaguely insectoid robotic figure with orange armor that has a brown, blue, and lime secondary color. It has a domed head with slitted red eyes sitting on top of an arrow-shaped brown collar. This symbol appears on its chest and shapes its navel, with a blue stripe in between them. It has broad, domed shoulders with lime spots that resemble eyes; causing its torso to resemble an open mouth. Its legs are armored in orange, with brown jewels at the knee, and its feet are shaped akin to shoes with the toes turned up in brown points. It has long brown forearms with elbow spikes and spindly tan fingers.


Kitamura began developing Red-B and Prototype Green-A shortly after he was promoted to chief of security for SOL Technologies. After completing the prototypes, he had them Speed Duel one another. An alert was triggered by Playmaker, who had invaded the Data Bank, and Kitamura deployed Green-A and Red-B to defeat Playmaker and capture his Ignis. Playmaker was initially able to evade them, but Green-A caught up to him and engaged him in a Speed Duel. Red-B caught up to Playmaker after Green-A discarded his entire hand and attempted to strike him, but it was stopped by Blue Angel, who Speed Dueled it herself. Both Duelists focused on effect damage, but Red-B was unable to defeat Blue Angel, who took advantage of its open field to defeat it.


Prototype Red-B uses a "Tentacluster" Deck, which unlike Prototype Green-A , focuses on effect damage.
