8 Events Oda-sensei didn’t plan from beginning!

1- Vivi being a Princess.

2- Shanks appearing in Marineford War.

3- Portgas D. Ace being Gol D. Roger’s son.

4- Rob Lucci being villain.

5- Doflamingo and Corazon having blood relationship.

6- Shichibukai appearing in the manga. One Piece was originally supposed to be a story to fight Yonko, not Shichibukai.

7- Supernovas still surviving in New World. Oda thought about half of them would have dropped out already.

8- Trafalgar D. Water Law being an important character. Oda thought Eustass Kid would become an important character, though.
