Introduction
The Phase Phase Fruit is a Paramecia class Devil Fruit that was eaten by Chiyome "Sneaking Phantom" Blitz, former Revolutionary and now current member of The Jolly Pirates.

Usage
The Phase Phase Fruit's power is chiefly make the user permanently intangible, allowing anything to pass through him/her effortlessly. However, this does not apply to common Devil Fruit weaknesses, such as seawater or Sea Stone. In fact, whenever the user would come into contact with the Devil Fruit's weaknesses, the user will lose his/her intangibility for as long as the weakness is applied to him/her. On the other end of the spectrum, the only other materials that can come into contact with the user, would be anything s/he would be carrying on his/her person at the moment when s/he ate the fruit, or when s/he regained his/her powers. An example would be a knife carried in a small holster for battle. As long as the knife has been carried by the Phase Phase Fruit's user before the user gained/regained his/her abilities, the knife will still be capable of being held by the user, as well as still being capable of cutting objects that aren't a part of the user's body. The same can go for any weapon (like firearms) or object, such as a pack of cigarettes. If the object were to ever be separated from the user however, the user would be unable to grab hold of it again, unless s/he were to lose his/her powers.

It should also be noted as well, that if anything were to have passed through the user while one of the fruit's weaknesses were applied (such as Sea Stone cuffs being attached while phasing through a wall,) the user will become tangible again, and will either be stuck within something (such as the aforementioned wall scenario,) or have something stuck within him/her (such as a bullet.) If the user were to be stuck within something, there will be no damage done to the user, albeit, it'll be beyond difficult to remove the user from said object, since the two would have merged to some degree. If the user were to regain his/her powers while stuck (again, one possible way is through removing Sea Stone from the user,) then the user will become able to phase through the object, thus making him/her unstuck.

Strengths
A major strength of this fruit is the power to phase through anything, so long as it doesn't retain any Devil Fruit weaknesses. This means that as long as the user isn't covered in seawater (or any water that could be considered "from the ocean,") or has any Sea Stone attached to him/her, then the user would be capable of surviving virtually any attack, as it would pass through him/her in an instant. Another key strength that might not be as widely known, is the ability to assist the Phase Phase Fruit's user in espionage, making his/her spying and assassination attempts easier to perform, since all the user would have to do is silently pass through walls and doors in order to get where s/he wants to go. This power doesn't apply JUST to espionage as well. This power can potentially allow its user to access otherwise unreachable areas by foot. Almost nothing is beyond the reach of a tactful user of the Phase Phase Fruit.

Weaknesses
The user suffers from standard Devil Fruit weaknesses.

Attacks
 Vanish:  This is the primary technique that Chiyome Blitz uses when she activates her powers. By removing the Sea Stone lined gloves she wears, Blitz can travel through anything she wants with ease. This "technique" is used mostly when Blitz wishes to go somewhere inaccesible, hide (usually inside a wall,) or simply set up a surprise attack.

Trivia

 * The Phase Phase Fruit was originally created to help give Chiyome Blitz, its user and eater, a power to use that would also reference her espionage skills.
 * The Phase Phase Fruit is one of the least offensive Devil Fruit in the world, thus forcing its user to rely on his/her own strength.
