The main projectile-based ability and staple of the series, Kirby gains the use of a boomerang blade that homes in back onto him after flying forwards. Kirby puts the blade on top of his hat when not in use, and the hat itself looks like a duck with wings at the side, and eyes which resemble Kirby's own. Because of the homing nature of the boomerang, jumping over the boomerang when it is returning causes it to overshoot backwards and take out anyone behind Kirby as well.
One of Kirby's six Animal Friends. Rick is a roly-poly hamster, almost as large as Nago, and equally roly-poly cat. Rick made his debut in Kirby's Dream Land 2, and like all Animal Friends, he shares and augments Kirby's Copy Abilities. Rick's personal relationship is with his love interest, Pick. Rick appears in Kirby: Right Back at Ya!, living beneath the roots of Acore the great tree, but his relationship with Kirby isn't what it was in the preceding games. Kirby and Rick are rarely seen together, and directly interact even less, but they are still friends nonetheless.
Kirisakin is an immensely powerful mercenary monster, fought during the war where Star Warriors went against Nightmare. He was hired by Nightmare Enterprises to attempt to steal Galaxia, the same sword that Meta Knight and Garlude were sent to retrieve. They met in combat and Kirisakin took Garlude's life, but Meta Knight managed to escape with Galaxia. A very long time later, during the events of Kirby: Right Back at Ya!, Customer Service sent him to track down Silica, the daughter of Garlude, after a tip-off by King Dedede. He bested Meta Knight, Sword Knight, Blade Knight, Silica, and Kirby before Kirby managed to get his hands on Meta Knight's Galaxia and finish him off with a sword beam.
