During the Lighthouse War, he led Golem Squadron in Operation Dual Wielder. He helped secure air superiority over the Chopinburg Rainforest. However, he was then forced to retreat after an enemy Arsenal Bird arrived, and was helpless to prevent the death of Brownie at the hands of Mihaly. After the events of Operation Lighthouse Keeper, he is not seen again and his fate remains unknown.
