Though not explicitly named until much later, Shanks uses a form of "Haki" (spiritual energy) to glare at and scare off the Sea King.

This episode explains his recklessness and unwavering loyalty. He learned from Shanks that being a pirate isn't just about fighting; it’s about knowing when a fight is worth it and protecting one's friends.

Fans often distinguish between the two main English versions of this episode:

During a tavern feast, Luffy unknowingly eats a treasure Shanks brought back—the Gomu Gomu no Mi (Gum-Gum Fruit). This grants him a rubber body but permanently robs him of his ability to swim.

Before departing, Shanks entrusts Luffy with his prized straw hat, making him promise to return it only once he has become a great pirate. Character Analysis
