One Piece — "That didn't hurt! 'Cause I'm made of rubber!"
From Volume 1 - Chapter 2 / NETFLIX One Piece - Season 1 Episode 1. After being trapped in a barrel and found by Coby, Luffy encounters Alvida, a fearsome pirate with a brutal mace. Though he is not a bounty hunter after her like she'd hope, he is still an intruder, one that she intends to kill. Luffy does not have any fear, because he's the stretchy kind of pirate!!
(Note: Yes! I am making moment comparison posts with the live-action series, I love it!! You're all free to make requests, but keep in mind that the moment has to have happened in the manga, or at least the anime. As much as I liked scenes like Nami and Kaya discussing money, or Arlong threatening Buggy, I can't post these scenes because there's nothing to compare them to. The same, of course, goes both ways. So scenes like Usopp disbanding the Usopp pirates, or Zoro stabbing himself against Cabaji, can't be done either.)
