1. Ice system: frozen fruits

The ability of ice system can be displayed by many people in the One Piece world, such as the ability of Melissa Zhou fruit eaten by Don Quixote's family cadre Snow Girl Monet to belong to the ice system, and the yellow fruit ability held by Straw Hat Pirates musician Brooke also has certain ice properties, and it is located in

Kuzan's frozen fruit is so powerful that it can even make an icy volcano erupt!

2. Hot system: magma fruit

The hot system should be a relatively powerful category of devil fruit in One Piece's world, such as magma fruit, burnt fruit, hot fruit, explosive fruit, etc. It is not difficult to see that none of them are weak. However, in the official setting, the magma fruit is temporarily in the top position, which has absolute suppression ability to the burning fruit representing the flame.

3. Thunder and lightning system: thunder fruit

Thunder fruit is known as "one of the strongest devil fruits", so it is natural that it is at the apex of the demon fruit ability of thunder and lightning system. But so far, there is no demon fruit strength of other thunder and lightning systems in One Piece, and the natural system Yunyun fruit that may appear in the future may be this kind.

4. Medical Department and Space Department: Surgical Fruit

Trafalgar's surgical fruit is the most valuable demon fruit ability in the One Piece world so far, and it is the demon fruit ability that all doctors dream of, which is naturally at the top of all medical departments.

Especially its power of giving others eternal life is the ultimate in medical skill! Moreover, its manipulation of space is absolutely far above the fruits of doors and castles, and its comprehensive value is far beyond imagination!

5. Animal system: the fruit of the immortal bird

The value of the animal system is very high, even the natural system is far from being comparable to it. Marco, the first captain with white beard, is also called the immortal bird because of his fruit ability, which is the closest animal system fruit among pirates and has great potential.
