when does robin join the crew

Nico Robin first joins the Straw Hat crew at the end of the Alabasta (Arabasta) arc, in anime episode 130, titled “Beware Her Scent! The Seventh One is Nico Robin,” which adapts manga chapter 218.

Quick Scoop: When does Robin join the crew?

In the story, this moment happens right after Luffy helps save Alabasta and Robin survives the destruction of Crocodile’s plans. She then suddenly appears on the Going Merry, tells Luffy he’s responsible for saving her life, and basically invites herself onto the ship, becoming the crew’s archaeologist.

Many fans also talk about a “second” big joining moment: Robin temporarily leaves during the Water 7 arc and emotionally returns to the Straw Hats in Enies Lobby, which some viewers see as the point she fully accepts them as her family. But if you’re asking strictly “when does Robin join the crew,” the official first join is Alabasta, episode 130 / chapter 218.

So, in short: Robin joins the crew right after the Alabasta arc, in episode 130 (manga chapter 218).
