Final Weapons are weapons Kirby uses when he battles a final boss, such as Dark Matter. Some of them require assembly before they can be used.
In the Games
Kirby finds seven shards scattered across Dream Land and gathers them together to form the Star Rod, which he uses to defeat Nightmare.
By gathering the Rainbow Drops from the Rainbow Islands, Kirby can form the Rainbow Sword to combat the Dark Matter that has possessed King Dedede at Dark Castle.
Using the power of the Heart Stars given by the inhabitants of Pop Star, 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.
Using the power of the Dream Fountains found on the distant planets, Kirby assembles the Starship to prevent Nova from intentionally ramming into Pop Star.
If all of the Crystal Shards have been found, they form into the fairies' power 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.
When Kirby goes into the Dimension Mirror, Meta Knight gives him the Master Sword so he can defeat Dark Mind.
After the battle with Daroach in his dark form, Kirby picks up his scepter, the Triple Star, and claims it as his ability. He then uses it to battle Dark Nebula in Gamble Galaxy.
