"WHO CARES WHO HIS DAD IS! HE'S MY BROTHER AND I WON'T LET YOU KILL HIM!"
"Luffy!!! Get out of here!"
Sengoku stepped forward and stared down at his tiny challenger. "It is our duty to eliminate the last of Roger's legacy. We will not allow another Pirate King to be born."
"Then you're wasting your time. Ace isn't the one you have to worry about. And Roger isn't either. He was the Pirate King, but he's dead now. I'm alive. And I'm going to be the next Pirate King! I'm going to be the greatest pirate ever – and I won't let you hurt anyone I care about! Not Robin! Not Zoro or Nami or Usopp or Sanji or Chooper or Franky or Brooke! And not Ace!"
The world held its breath as Luffy settled his hat firmly over his head, and took a fighting stance against the best the Marines had to offer.
"So get out of my way if you don't want to get hurt."
Years later, many would cite this as the moment Strawhat Luffy stopped being a pirate – and became a Power.
