One Piece Chapter 999 will reveal Kaido's devil fruit, which seems to question the law of the anime's universe. As this seems to oppose his real ability, what does this superpower entail?

One Piece Chapter 999 spoilers hinted at Kaido's devil fruit power. He has "Uo Uo no Mi or Fish Fish Fruit, Mythical type," instead of dragon fruit that everyone assumes he has.

According to BlockToro, fans know Kaido is a dragon, who eats the "human-human fruit," which is now proven wrong. With the revelation that he possesses a Fish devil fruit, everyone wonders how he can fly and breathe fire.

Per the Chinese and Japanese legends, a Koi fish that swam upward the current turned into a dragon when it entered the ancient Dragon gate. This might have happened to Kaido, who possibly turned into a fish and swam up into Wano.

From here, he might have awakened his devil fruit powers. Fans may also see in One Piece Chapter 999 if Kaido or any Zoan Fish devil fruit user can swim or not.

The anime creator Eiichiro Oda earlier said the devil fruit makes the users heavy in the water, making them unable to swim. However, fish and merman can still breathe under it, so it will never die, like what happened to Jack.

Inquisitr added the upcoming installment would show the discussion between Kaido and Big Mom. The talk would reveal The Beast Pirates captain had a debt to the Big Mom Pirates captain, and it was his controversial devil fruit.

Linlin gave this power to Kaido when Rocks, the legendary pirate group, fell, and its members went on their separate ways. They would also talk about the Straw Hat Pirates navigator, Nico Robin.

Linlin asked Kaido to keep Robin alive as she was the only one who could read the ancient texts. Kaido would then ask if the girl with three eyes, who might be Charlotte Pudding, could not read the primeval messages.

In addition, One Piece Chapter 999 will also give a glimpse of Marco the Phoenix, flying to the roof to Kaido's location, along with Roronoa Zoro. King and Queen will see these two and immediately transform. They will try to stop Zoro and Marco from reaching Kaido.

One Piece Chapter 999 is set to be out on Sunday, December 20, at midnight, Japan Standard Time, per HITC. It will later drop in other parts of the world for the international audience to see. It will be out at 9 a.m. Pacific Time, 11 a.m. Central Time, noon Eastern Time, 5 p.m. British Time.
