What if Luffy were captured by Garp and made to join the Marines?
He never received Shanks's hat, and never met Ace and Sabo. To keep Luffy from resisting the Marines like Dragon, Garp raised him in Marineford from the moment he was born.
He enlisted his friends, subordinates, and students to help.
In this situation, would Luffy still become a pirate?
This is a story set in a parallel little world.
Bonus scene:
"Vice Admiral Garp! Vice Admiral Garp!"
"Huh?"
"Major Monkey says he's going to become a pirate! He just stole a battleship and said he's setting sail."
"You little brat! Does he want to taste Grandpa's Iron Fist?"
"Also, Admiral Akainu has already gone after him."
"..."
"Take me there, now! Hurry!"
A pirate's flag stands for freedom, and Luffy is free too!
