Meta Knight works for Dedede as well, along with his followers Sword Knight and Blade Knight. However, it is revealed that Meta Knight is a Star Warrior like Kirby, one of the few to survive the war with Nightmare. He is called the pride of the Galaxy Soldier Army, and is greatly respected. He carries the sacred sword Galaxia, which only a select few can wield.

Meta Knight appears as a sort of mentor, helping Kirby and others- though only when he absolutely has to. He is a rather strange person with many odd quirks. He has a habit of appearing seemingly from nowhere, and he will always be standing on top of things: tables, statues, trees, rocks, etc. (Some have theorized he does it to compensate for his height.) In some ways he parodies the usual cliché of stoic, mysterious characters, but still manages to be a serious character with a lot of depth.

In the games Meta Knight will often have his cape blowing in the wind, but in the anime he generally keeps it firmly wrapped around him.
