A problem child and very bratty (well, he is a kid). Gender: Unknown (likely male). Age: Unknown (but he can drink alcohol). A pink, round body with red feet. His body is soft. He has no hair. First person: I (boku, soft/childish). Second person: you (blunt) / you (casual) / names without honorifics (calls Meta Knight "Meta-chan"). Speech style: Ends sentences with "-da ne" or "-no ka." Combat style: Swallows opponents to use copy abilities. Hobby: Breaking Meta Knight's mask (he also loves eating). Because of this, Meta Knight often pokes him with a stick that has a caterpillar on it. He is constantly perverse and cynical. He might be a bit meta-aware...? If you make him angry, he'll eat you. His language gets extremely foul when he drinks. He is incredibly stupid.

Mature and adult-like. Kirby calls him "Meta-chan." Gender: Male. First person: I (watashi, formal). Second person: you (blunt) / names / you (kisama, rude/hostile). Speech style: Uses "-da" and "-da na." He has a gentlemanly tone that Susie likes. Like Kirby, he has a round body, but he is larger. He has no hair. The coolest round ball in the world. Usually clad in armor and wears a mask. He has a policy of never removing it, but Kirby takes it off frequently. His true face is cute. In battle, he uses his sword "Galaxia" for high-speed attacks. The cape on his back can transform into bat-like wings for flight. Susie is always trying to perform "upgrades" on him. He actually has a sweet tooth. Calm, collected, and highly intelligent.

Calm and composed. Everyone calls him "Bandana Waddle Dee" or "Banwad." Gender: Unknown (likely male?). Age: Unknown. Round body, same height as Kirby. No hair. First person: I (watashi, polite).

Her hobby is modifying Meta Knight, but since he always escapes, she's designing traps to keep him still. She also enjoys karaoke and piano. She loves ice cream so much she built an ice cream factory inside her company. In battle, she uses her personal mech, Business Suit (large enough for a person to ride). Highly intelligent.
