Usopp leaves (temporarily) in the Water 7 arc , in the anime around Episode 235–236 , when he has his big fallout with Luffy over the Going Merry.

What Episode Does Usopp Leave the Crew?

Usopp’s emotional “I’m leaving the crew!” moment happens in Water 7 , after the Straw Hats learn that the Going Merry can’t be repaired enough to continue sailing safely.

This leads to a massive argument between Luffy and Usopp about whether to abandon the Merry, which hits Usopp right in his pride and his feelings of weakness in the crew.

Exact Episode (Anime)

  • Usopp verbally declares he’s leaving and walks away from the crew in Episode 235 (English-dub and some listings directly title it around “Usopp Leaves the Crew”).
  • The famous Luffy vs Usopp duel for the Going Merry happens in Episode 236 , often cited as the core “Usopp leaves the Straw Hats” episode.

So if you’re asking “what episode does Usopp leave the crew?” for watching order or rewatch:

  • Watch: Episode 235–236
  • The key departure moment people usually refer to is Episode 236 (the duel), but the actual “I’m leaving” line is in Episode 235.

Quick Story Context (No Heavy Spoilers Beyond That Arc)

  • The Going Merry is declared unfit to sail by shipwrights in Water 7.
  • Luffy decides the crew must get a new ship , which crushes Usopp because of:
    • His emotional bond with the Merry.
* His insecurity about being **one of the weakest** members and recently losing the crew’s money.
  • Feeling useless and left behind, Usopp quits the crew and challenges Luffy for ownership of the Merry.

This turns into one of the most emotional fights in One Piece , where both are fighting with pride, loyalty, and heartbreak more than pure hatred.

Does Usopp Come Back?

Yes – Usopp’s departure isn’t permanent.

  • He rejoins the Straw Hats later at the end of the Post–Enies Lobby / Water 7 follow‑up, in Episode 323 , after resolving his pride and apologizing.
  • That episode is titled “Departure from the Water City! The Distinction of a Man, Usopp's Duel” , marking his full return to the crew.
