Part 1 (Luffy Back in Time Pt. 1)
In Chapter 1100+/-, Luffy will go back to the past, 900 years and 9months ago, and meet two brothers. He will time travel back with the help of three devil fruits - his own, Franky's, and Bonney's. Franky will get Kuma's fruit, who died saving Bonney.
(EDIT: Might not involve Bonney.)
Luffy will meet two brothers. Older Brother - Crown Prince Im. Younger brother Prince Dyras (future Joyboy). Dyras is known as the "monkey" while Im is the wise one. Im is secretly working with outsiders (20 nations) to set up coup to steal the crown because he found out Dyras will be the next heir.
This is literally whats going to happen with the change that oda made to fujitora, kizaru and possibly bonney's fruit to send luffy to the past.
THE LEAKS WERE RIGHT ALL ALONG.
