Suna Suna no Mi

The Suna Suna no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into sand at will, turning the user into a Sand Human (砂人間 Suna Ningen).     "Suna" (砂) means "sand". In the Viz Manga, 4Kids and FUNimation dubs, it is called the  Sand-Sand Fruit. It was eaten by  Crocodile. Its powers were first shown, but not fully explained, being used to dry a flower in a glass during the call between Crocodile and Sanji in Little Garden. The power of the fruit was finally shown in a battle between Crocodile and  Puppu's  crew.

Strengths and Weaknesses
A review on the powers of the Suna Suna no Mi.This fruit is quite powerful, even among Logia, as it allows for a greater variety of abilities, rather than just normal element control. It also allows the user to locate quicksand, set off sandstorms and absorb liquids. Such a variety is not seen with any other Logia. It is also the first and only known Logia type fruit that can naturally counteract its own weakness, and is even stronger in desert areas (granting Crocodile virtual invincibility).

It allows the user to transform into sand at will, as well as control it. Crocodile has trained himself to transform into sand by reflex, and is thus capable of avoiding sneak attacks (which untrained Logia-class users tend to not have time to transform to evade). This fruit allows Crocodile to sense anything that is moving through sand (he uses his power to sense underground rivers). Its power can also be honed to the point where the user could also dry anything the user grasps, causing the living such as humans and plants to wither through dehydration, and also cause all other matter like rocks and land to crumble to dust and sand; only metallic or ferrous substances are spared from this dehydration effect.

However, Crocodile turns solid when in contact with liquids, including blood, although it does seem that only certain liquids work, or it is based on how the liquid had contact with him. Crocodile was bitten by a water-drenched Luffy but received no harm.

He also turned to sand when Vivi attacked him (even though he was drinking wine moments before), due to the sand sticking together. This weakness can be rendered useless, due to the ability to absorb the offending liquid. Other than that, the user is also affected by the standard Devil Fruit weaknesses.

Usage
Crocodile mastered the Devil Fruit Suna Suna no Mi to the point of perfection where he can turn into sand reflexively if attacked. This ability was proven true when Doflamingo cut his head off while he was distracted. While in a desert area, his powers make him nearly invincible. He can also suck all the moisture out of any object, living or non-living, by placing his right hand on them. This ability makes him able to utterly destroy his surroundings.

Crocodile has shown to create sand blades that can slice through the ground, create sandstorms, activate quick sands, and cause dehydration by physical contact. In addition, Crocodile has shown to transform his arm into sand in order to extend his reach for his hook, as a long range capture and strike.

Crocodile's named attacks are the follows: Desert Spada almost hitting Luffy.*Desert Spada (砂漠の宝刀（デザート・スパーダ） Sabaku no Hōtō [Dezāto Supāda], literally translated as "Treasured Sword of Desert"): Crocodile forms his right hand into a loose blade of fast-moving sand and then stabs it into the ground, extending it along the ground like a torpedo, splitting anything in its path, including the very ground itself, through extreme and focused erosion, created by the sand blade, which is strong enough to slice a man in half. When he used this on top of King Cobra's palace, the attack also generated a static surge that ran with the blade, nearly hitting Luffy in the process. "Spada" is the Italian word for "sword". Similarly, "Espada" is Spanish and Portuguese for sword. In the 4Kids dub, this attack is called Desert Dagger, and retains its original name in the FUNimation dub. Crocodile using "Sables" to send Minokoala flying.*Sables  ( 砂嵐（サーブルス）   Suna Arashi [Sāburusu], literally translated as "Sandstorm"): Crocodile summons a massive tornado of sand and sends it on a rampage. Once this sandstorm grows large enough, not even he can stop it. A variation of it is seen when Crocodile makes his first appearance in the Alabasta arc. He makes a sandstorm that can suck the water out of living things and is apparently able to crack steel. Another usage is to send people flying with this technique, as he did with many pirates who interfered with his attempts to kill  Whitebeard,   as well as sending  Jinbe  and  Monkey D. Luffy  out of  Admiral  Akainu's way. "Sable" is French for "Sand" so the term "Sables" can mean "Sands", but it can also refer to a "Sandstorm". "Sable" is also Spanish for "Saber". This attack retains its original name in the Viz Manga and FUNimation dub. In the 4Kids dub, this is called  Sandstorm. Crocodile unleashing the "Desert la Spada".*Desert la Spada  ( 砂漠の金剛宝刀（デザート・ラスパーダ）   Sabaku no Kongō Hōtō [Dezāto Rasupāda], literally translated as "Adamant Treasure Sword of Desert"): An altered version of  Desert Spada. Crocodile now forms several solid blades with fan-shaped edges instead of one large blade made from sand. This is the only time Crocodile has formed solid objects out of sand, although a sufficiently powerful blow will shatter it back into sand. In the eighth movie, rather than being four solid blades, this move is more like two buzz-saw like blades that are less solid. This attack is simply called  Desert Spada  in the Viz Manga and FUNimation dub,  Desert Slasher  in the 4Kids dub, and  Desert Rapier  in the English version of One Piece: Grand Battle! Rush!. This attack keeps its name in the FUNimation version of Movie 8. Crocodile uses the "Desert Grande Spada" to stop Akainu.*Desert Grande Espada (砂漠の大剣（デザート・グランデ・エスパーダ）Sabaku no Taiken [Dezāto Gurande Esupāda], literally translated as "Large Sword of Desert"): An altered and enhanced version of Desert Spada. Crocodile forms a large version of his Desert Spada attack with more powerful effects. "Grande" is Italian, Spanish, French and Portuguese for "large", "great" or "big". It was first seen used to slice Akainu in half to protect Jinbe and Luffy. When Crocodile used this move he did not name it, but it was named in the game One Piece: Gigant Battle.
 * Desert Girasole (砂漠の向日葵（デザート・ジラソーレ） Sabaku no Himawari [Dezāto Jirasōre], literally translated as "Desert Sunflower"): Crocodile creates another loose sand blade from his right hand with Desert Spada. Like Desert Spada, he stabs it into the ground causing the area in front of him to collapse. However, a giant pit of quicksand will be formed instead, with the sand being taking away by underground rivers (which he can detect). Anything caught in the pit will be sucked in and buried alive. This attack can only be done in a desert terrain. "Girasole" is the Italian word for "Sunflower". This attack retains its name in the Viz Manga and FUNimation dub, and in the English version of One Piece: Grand Battle! Rush! (dubbed by 4Kids), this technique is called Desert Swamp.
 * Barchan (三日月形砂丘（バルハン） Mikazukigata Sakyū [Baruhan], literally translated as "Crescent-Shaped Dune"): Crocodile swings his right arm forward while leaving a crescent shaped trail of sand behind it. Anything hit by that trail is instantly robbed of all moisture because of Crocodile's dehydration ability. A "Barchan" is a crescent-shaped sand dune. This is called Crescent Cutlass in the Viz Manga, the FUNimation dub and subs, and the English version of One Piece: Grand Battle! Rush! and Desert Cutlass in the 4Kids dub.
 * Ground Secco (干割れ（グラウンド・セッコ） Hiware [Guraundo Sekko], literally translated as "Mud Crack"): Crocodile places his hand on the ground and uses his dehydration ability to dry out a huge area around him, turning it into a desert wasteland. When he does this, it also can cause the area around him to crumble and cave in, causing unfortunate foes to fall to their death. "Secco" is Italian for dry, while "Seco" is Spanish and Portuguese for "Dry". This attack is called Wasteland Tremor in the 4Kids dub.
 * Ground Death (浸食輪廻（グラウンド・デス） Shinshokurinne [Guraundo Desu], literally translated as "Cycle of Erosion"): An extremely strong version of Ground Secco. However, Crocodile not only dries up the ground, but anything and everything on it including people and even buildings, all of which is transformed into sand if it has steady contact with the ground. The speed at which things dry also seemingly increases. In the 4Kids dub, this attack is called Wasteland Cataclysm.
 * Desert Encierro (砂漠牢（デザート・エンシエロ） Sabaku Rō [Dezāto Enshiero], literally translated as "Desert Prison"): Crocodile grabs someone with his right hand, then slowly or quickly drains the moisture from them with his dehydration ability. This leaves them in a withered and seemingly fleshless state. "Encierro" is the Spanish word for "Imprisoning". In the 4Kids dub, this is called Desert Prison.
 * Sables: Pesado (砂嵐 重（サーブルス ぺサード） Suna Arashi: Jū [Sāburusu: Pesādo], literally translated as "Sandstorm: Heavy"): Crocodile gathers a swirling mass of extremely dense sand in his hand, then hurls it at his opponent, causing a massive shock wave upon impact. "Sables" is French for "Sands" and "Pesado" is Spanish and Portuguese for "Heavy". This is called Sandstorm Burden in the English version of One Piece: Grand Battle! Rush! and Sandstorms in the 4Kids dub.

Trivia

 * The color of the sand changed in the anime, from a full light brown to a grayish light brown.
