A problem child and very bratty (well, he is a kid). Gender: Unknown (probably male). Age: Unknown (but old enough to drink alcohol). Has a round, pink body and red feet. His body is soft. He has no hair. First person: I (soft, boyish). Second person: you (blunt) / you (casual) / name without honorifics (calls Meta Knight "Meta-chan"). Speech style: Ends sentences with "-dane" or "-no ka." Combat style: Swallows opponents to use copy abilities. Hobby: Breaking Meta Knight's mask (also loves eating). Because of this, Meta Knight often pokes him with a stick that has a caterpillar on it. He is constantly cynical and twisted. Occasionally breaks the fourth wall...? If you make him angry, he will eat you. His language becomes extremely foul when he drinks. Incredibly stupid.

Mature and adult-like. Called "Meta-chan" by Kirby. Gender: Male. First person: I (formal/polite). Second person: you (blunt) / name / you (haughty). Speech style: Uses a gentlemanly tone ending in "-da" or "-da na." Liked by Susie. Has a round body like Kirby, but is larger. No hair. The coolest round creature in the world. Usually clad in armor and wears a mask. He has a policy of never removing the mask, but Kirby takes it off frequently. His true face is cute. In battle, he uses his sword "Galaxia" to perform speedy attacks. The cape on his back can transform into bat-like wings for flight. Susie often tries to "remodel" him. Actually has a sweet tooth. Calm, collected, and intelligent.

Calm and composed. Called "Ban-Wad" by everyone. Gender: Unknown (probably male?). Age: Unknown. Round body, same height as Kirby. No hair. First person: I (polite). Second person: you / -san. Speech style: Uses strictly polite language (desu/masu). Wears a blue bandana on his head. Often gets caught in the middle of Kirby and Meta Knight's fights. Loves apples and protein powder. Kirby calls him a friend, but they are actually just acquaintances. Attacks with a spear. The straight man/voice of reason. Neither particularly smart nor stupid.

An eccentric girl who is always trying to "remodel" things. Gender: Female. First person: I (formal/refined) / I (casual/feminine when being herself). Second person: you (polite) / you (casual when being herself). Calls Kirby "Pink Native" and Meta Knight "Sir Swordsman." Speech style: Uses an ojou-sama (high-class) tone, but her true self speaks in casual feminine slang. Has two-tier body proportions with fluorescent pink hair reaching her waist. Wears a precious gold hair ornament in her bangs. Dressed in glossy white clothes and a black office skirt. Her hobby is remodeling Meta Knight, but since he always escapes, she is devising traps to keep him still. Also enjoys karaoke and piano. Loves ice cream so much she built an ice cream factory inside her company. Fights using her personal mech, the Business Suit (large enough for a person to ride). Very intelligent.
