Stone

"Kirby rocks with the Stone ability! Slide down slopes and squash your enemies in seconds flat! With so many possible transformations, who knows what he'll turn into next!"

- Stone's Flavor Text

Stone is one of Kirby's Copy Abilities.

General Information
Stone is almost entirely a defensive ability - unless Kirby happens to use it above a foe's head. However, in Kirby's Return to Dream Land, Stone gets a move called Stone Uppercut, which gives another way to use the power for offense. Stone is an easy way to beat bosses with minimal damage by simply dropping over the boss's head and staying in stone form until the boss moves away. It can also avoid devastating full-screen attacks, like Marx's black hole. The hat looks somewhat like a samurai helmet with a red plume on the top and a guard on the back, with a star on the forehead piece.

The Stone hat originally had the same design as the Ninja hat with different colors, but Kirby wears a different one as of Kirby's Return to Dream Land. It has a rocky appearance similar to Ice's. A similar brown hat was also intended for the unreleased Kirby GCN.

Super Smash Bros. series
In the Super Smash Bros series, Stone is Kirby's Down Special attack. He can only turn into his distinct rock form in Super Smash Bros., but in Super Smash Bros. Melee and Super Smash Bros. Brawl the ability acts more like its Kirby Super Star variant, turning Kirby into a variety of heavy objects. These include his normal Stone form, a 100t Weight, a garbage block from Panel de Pon (in the floral style associated with the character Lip), a spiked ball, and a Thwomp from the Super Mario series.

In Super Smash Bros. for Nintendo 3DS and Wii U, Kirby can change his stone using Custom Moves. He can now also use Grounding Stone or Meteor Stone. Grounding Stone allows Kirby to bury opponents that he lands on, but it takes longer for him to transform. Meteor Stone gives a meteor effect to opponents hit by the attack, but it takes longer to transform out of.

Like in Kirby's own games, he's still invulnerable to attacks (except grapples and throws) regardless of what he turns into and only hurts other fighters if used over their heads. The ability can be also used to attack foes from above, which is the most frequently used form of this attack. The Stone also slides down slopes, so care needs to be taken when using the move near slopes. Also, in Super Smash Bros. Brawl, the attack can be broken, as anything damaging enough to do at least 30% damage, despite inflicting no damage, can force him out of stone form with full knockback.

Kirby: Right Back at Ya!
In the anime, Kirby keeps the traditional Stone hat from Super Star, but his skin turns stone-gray instead of brown. Surprisingly, the ability works more like one from Kirby 64, specifically the Double Stone mix, allowing Kirby to turn into a giant, pink stone statue of himself which can walk and jump, albeit very slowly.

Stone Kirby relies on his sheer bulk to crush enemies. In the transformation sequence, Kirby's skin changes to gray. A flash of light forms his hat and he puts it on.

Trivia

 * In certain games, Stone can take on a variety of transformations; many of them are uncommon.
 * In Kirby Super Star and Kirby Super Star Ultra, Kirby can become a golden statue of Mario and a bronze statue of Samus (which pays homage to Metroid II: Return of Samus ' s box art).
 * In Kirby's Return to Dream Land, he can transform into the legendary Dragoon; Marx on his ball; a Star Block; a carved image of Wham Bam Rock in his Kirby Super Star Ultra design; a golden 8-bit statue of Kirby from Kirby's Adventure; a golden statue of Meta Knight and Galacta Knight; a golden statue of the Star Rod, Magical Paintbrush, and Triple Star; and one statue of Rick, Coo, and Kine as opposed to individual statues of the three.
 * In the New Challenge Stages mode of Kirby's Dream Collection: Special Edition, most of the Stone forms appear in Smash's moveset, with a few new transformations - there is now a golden 8-bit King Dedede swinging his hammer (once again from Kirby's Adventure), the 8-bit Kirby now has a "20th" mark above him, and there is a golden Magolor.
 * In Kirby: Triple Deluxe, Kirby can transform into a statue of Bandana Waddle Dee, Meta Knight, and King Dedede; a dark steel statue of Ultra Sword Kirby brandishing his weapon; a pearl statue of four Kirbys from Kirby Mass Attack; a silver statue of the Lor Starcutter; a golden statue of Drawcia and Dark Nebula; a golden statue of Marx and Magolor; and a golden 8-bit statue of Kirby (Kirby's Adventure) holding the Star Rod.
 * The Egg Statue -- a golden block depicting the HAL Laboratory logo -- is the rarest transformation in the series. It appears in Kirby Super Star Ultra, Kirby's Return to Dream Land, Kirby's Dream Collection: Special Edition, and Kirby: Triple Deluxe.
 * Stone is one of the few abilities to have a multi-form attack; the others being Ultra Sword, Archer, and Circus.
 * The volcano that Stone Kirby can transform into is actually Mt. Fuji, a famous Japanese mountain.
 * In Kirby: Nightmare in Dream Land, this ability still turned Kirby brown, even in multiplayer. This was removed in later games to prevent confusion, eliminating Kirby's color-changing feature.
 * Oddly, in Kirby: Nightmare in Dream Land, the icon was a Waddle Dee sitting on Transformed Stone Kirby. In Kirby & The Amazing Mirror, it was Stone Kirby landing on a Waddle Dee. It was probably changed because the function of the ability went from a plain block to the round stone of most games.
 * This also makes it the only ability in Kirby: Nightmare in Dream Land to get a different icon in Kirby & The Amazing Mirror.
 * In the credits of Revenge of the King and the original Kirby Super Star's Milky Way Wishes credits, the Mario statue is seen just before the credits finish. A real, 'flesh' Mario is seen at the end of Kirby Super Star's credits, however.
 * In Kirby Super Star Ultra, if Kirby happens to morph into his Macho Statue form and he's on a slope, the statue will appear to actually be posing. When sliding, this form automatically changes to include different poses (two in Kirby Super Star) depending on how steep the hill is.
 * In Super Smash Bros. Brawl, Kirby's down B move is the stone transform. Some of the original transformations make a reappearance in this form.
 * Until Kirby's Return to Dream Land, Stone Kirby's hat was the same as Ninja Kirby's hat, just a different color.
 * The Thwomp that Kirby can transform into in Super Smash Bros. Melee is based off of Thwomp's design from Super Mario 64. The Stone's design was not updated for Super Smash Bros. Brawl despite the fact that Thwomp's design had drastically changed several years before the game's release. The Stone's design was later updated in Super Smash Bros. for Nintendo 3DS and Wii U to reflect Thwomp's New Super Mario Bros. U appearance.
