Water Water devil fruit

 

Throughout the One Piece series, we have seen various devil fruits but not a water water devil fruit. Water is a very common natural element like fire and ice so there must be a water water devil fruit. 

I think Oda must have thought about it and he is planning to introduce it soon. It has a same mystery like wind wind fruit.

It will be one of the strongest devil fruit in One Piece and there is some possibility that it is possessed by imu sama.

Let's see how it would look and work.

The Mizu Mizu no Mi (lit Water Water Fruit) would be a Logia-type Devil Fruit that will allow the user to control and become liquid water.

Appearance

The fruit resembles a blue watermelon with swirls on it.

Strengths

The major strengths of the fruit will be that it allow the user to become and control liquid water. When turned into water, they can not only let physical attacks phase right through them, they can also shapeshift into various water forms, including the shape of a human figure so that they can still partially interact with the environment. 

By gathering more water, they can increase the size of their water form. Out on the ocean, they can become the size of a titan, so long as they have a solid surface to stand on. 

While in their water form, they can turn their arms into water weapons and pressurize the water, making the water weapons hard enough to deal minor blunt-force damage, but nowhere near the amount of damage a stone or metal weapon could deal. 

They can also fire water as a pressurized jet, similar to power washing, allowing them to use a jet of water to shred through the opponent's body.

Weaknesses

The major weakness of the fruit will be that the user is heavily susceptible to dryness and electricity. An attack from Enel or Crocodile could leave them dead in a single hit. Being made of water, their body is a natural conductor, and Crocodile could just use his dryness powers to dry the user right up, killing them. The user could also be contained within a bottle or sponge, though this is highly unlikely.

The other problem is that Devil Fruit users are weak to being submerged. The user cannot swim, and their power is negated when submerged in water, just like all Devil Fruit users. So even if the user becomes water, they will turn back to normal and drown if they are submerged. Also, because of this water weakness, gathering water to increase their size can leave the user with flu-like symptoms after a prolonged battle.

There is also the fact that increasing their mass is dependent on gathering outside water, as the user cannot create water. In an area without any water to gather, the user must rely entirely on the water supply of their water form. And when in a dry, hot, heavily sunny area like a desert, the user is in danger of evaporating if they enter their water form.
