Sit-ups, version update, and martial spirit awakening!

Is he destined to follow Kaido's old path and become a stepping stone for Luffy to become the emperor?!

Fortunately, you are the child of destiny, and I am a time traveler.

If you have Nika, I can cultivate immortality.

However, the moment he bit into the fruit...

Space shattered! The atmosphere wailed!

The elemental body is the source of the earthquake, and the air vibrates when he raises his hand!
