Oda has so far only given four types of subordinate relationships.

Magma > burned

Frozen > Ice and Snow (Snow Lady Monet)

Weapons> Quick Slash (Maid Baby5 & Mr1)

Tonnage > weight (Don Quixote's big fat man and Miss Valentine's Day)

In fact, physically speaking, the temperature of the flame is much higher than that of magma.

The magma is more than 1,000 degrees dead, and you can imagine the sun in flames.

But Ace was indeed killed by Akainu, and it was obviously suppressed by the fruit rather than domineering.

Some people speculate: Ace was killed by Akaiu in order to protect Luffy, and there is no way to protect Luffy if he is elementalized.

But before, Ace had a trick against Akainu, and Ace was directly injured.

Some people speculate: In fact, magma is not only high temperature, but also liquid, so restrain Ace.

But Ace also had a trick against the pheasant, no matter how good it is, no matter how restrained the liquid is, it can't be more restrained than the cold ice of the pheasant, right?

So the only theory I can think of at the moment that is in line with the magma fruit's suppression of the burnt fruit without violating physics is that the demons in the devil fruit have a subordinate suppression relationship.

The Magma Demon is more powerful than the Flame Demon, and the Magma Fruit refrains from burning the Fruit.

In the same way, the rubber demon can be immune to the ability of the lightning demon, and the Anilu Ringing Thunder Fruit is ineffective against Luffy, and there is no breakdown voltage at all.

In fact, the terrible thing about lightning is not only the current, but also the high temperature.

The instantaneous maximum temperature at the time of lightning can reach 27,000 degrees Celsius, which is more than four times the temperature of the sun's surface.

Lightning on Mars is much more energetic, and one lightning bolt is equivalent to detonating several nuclear bombs.

What is rubber in the face of such a huge amount of energy?

So this can only be explained as restraint between demons.

In the same way, the Demon of the Dark Fruit is the King of Demons, so it can make other Devil Fruit abilities nullified, otherwise how can it be so powerful simply by relying on gravity?

Of course, this is just a more reasonable explanation for the Devil Fruit, and there will be no plot of fighting demons in the later part of the book. =^_^=

Anyway, who remembers that artificial devil fruits are afraid of water? 0.0
