Bastion (titled “The Cataclysmic Overlord”) is a member of the Grey Swarm, the main antagonists (they are sentient AI robots) of the single-player event game mode Extermination: Hunting Grounds in mobile PVP game War Robots by Pixonic. Originally, it was a robot planned to be playable alongside the other playable robots in all the other video game aspects but was cancelled in favour of Raijin’s design making it in the game. Years later, it re-debuts in here as the final boss of the game mode.
