Chiizuru is a typical girl: She loves clothes, kids and- "Shrimp Mayo". She is a part time worker at a corporation where she meets the person se hates most in the world- Ebisu Mayo. Chiizuru, at first, is mean in any way, shape or form to Ebisu. Slowly she develops mysterious feelings for Ebisu that are practically cemented after Chiizuru starts to help take care of Hana, Ebisu's niece.
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. The cape can be used to teleport, which is most likely how he appears from nowhere.
The main villain of the series who seeks to destroy Kirby by any cost. He has ruled Dream Land for 300 years (so he claims), and is still going strong, but is not regarded actually as a king. Despite the fact Dedede is greedy, scheming, and even outright sadistic- even going as far as to say that people’s suffering amuses him- no one has ever tried to dethrone him, despite the fact that he also threatens the children. He's actually harmless for the most part, but his intense dislike of Kirby compels to purchase monsters from Nightmare Enterprises and cause mayhem for the people of Dream Land. He loves buying new 'toys' and acts like a spoiled child despite his age. He's jealous of the attention Kirby gets, and while at first he even wanted to kill Kirby, later he focuses more on trying to kick him out or just make him look bad. Of course he has a kinder, gentler side, but it only shows in the most extreme of circumstances. (like in the De-appreciation-day episode where he played a prank on Kirby which blew him up which made Dedede upset that he thought he actually killed Kirby, and in the episode where a meteorite was going to hit Pop Star, so he built a playground to make up for his mistakes.)
