In the Games
Using the power of the Heart Stars given by the inhabitants of Planet Popstar, Kirby forms the Love-Love Stick. Using this weapon, he once again battles the Dark Matter (this time in the Hyper Zone) and eventually fights against Zero.
If all of the Crystal Shards have been found, they form into the fairies' Crystal, which then transforms into a powerful crystal shooting gun. Known as Ribbon's Shard Gun, Kirby grabs ahold of it and, with the help of Ribbon, flies to the skies of Dark Star to face 0².
During the first phase of battling Magolor, Kirby has to use three of the Super Abilities in order to defeat Magolor. Kirby finishes the final boss off with the Ultra Sword, first using it to break the final part of Magolor's barrier, and then landing multiple deadly slashes on him, before drastically increasing the Ultra Sword's size, and ending Magolor's first form with a powerful slash.
During the final battle with Queen Sectonia during Story Mode, Kirby uses the Hypernova ability that King Dedede and Taranza were able to provide with a Miracle Fruit. Kirby uses it to counter all of Queen Sectonia's attacks, spitting the flower buds at others to break Sectonia's barrier, and to inhale Queen Sectonia's laser and spit it back at her.
