The fourth boss faced by Kirby in Kirby: Planet Robobot. After Meta Knight tried to take on the invading Haltmann Works Company, he was captured and remodeled by Susie into a battle cyborg. He was equipped with missiles, lasers, and an altered version of his Galaxia. A subsequent upgrade named Mecha Knight+ gives him a large, scorpion-like tail.
A mass produced version called Stock Mecha Knight can be found in Meta Knightmare Returns and the True Arena.
