Ax Knight is the most common of the Meta Knights. He wears a skull mask, a viking-style helmet, and wields an ax nearly as big as himself. He serves under Meta Knight, but also played a role as a crewmember of the Halberd with in-game dialogue.
Kirby's Adventure and Kirby: Nightmare in Dreamland Edit
Ax Knight is one of the four Meta Knights that together appear as a recurring mini-boss. Once Kirby enters the room they inhabit, Meta Knight gives the command before disappearing, and the Meta Knights appear. Ax Knight stands in place, sometimes walking back and forth, as it swings it ax. It will occasionally throw its weapon like a Cutter, sometimes jumping over it as it comes back, similarly to Sir Kibble. In a rare few appearances, Axe Knight will slice its way across the room when spawned, turning and proceeding in the opposite direction once it reaches the end.
Kirby Super Star and Kirby Super Star Ultra Edit
In Super Star and its remake, Axe Knight behaves in the exact same way, with perhaps another move or two. The only exception is that it appears on its own, not having to follow Meta Knight's command to attack.
Axe Knight also doubles as a key character in Meta Knight's Revenge. He serves as one of the crew members who overlook Kirby's journey through the Halberd. He is aware of Kirby's destruction, and does not respond well to sending Heavy Lobster to tear through part of the ship to smite Kirby. (See quotes below.) Before Kirby's encounter with Meta Knight, Axe Knight appears along with other Meta Knights in an attempt to stop him. Obviously, this effort is in vain. In addition to his witty conversations with other crew members (sometimes, his comments and expressions prove to be in the least bit humorous), he also operates the Halberd, as seen in the opening cutscene.
