"Meta Knight is one of the 4 main characters of the Kirby series. He wields a sword called Galaxia. He first appeared in Meta Milk, where he and Kirby fight over the last cup of milk. He later appears in the SOOS series, where he befriends Marx and is given a lot more personality and is actually seen using his sword."
