Just so we're all clear, the One Piece anime is long. With over 900 episodes so far and counting, there's a lot to watch if you want to catch up. You'd think that by now, our main character Monkey D. Luffy would have become the best pirate of all time with the years he's had to reach his goal alongside his crew, The Straw Hats. But new characters, plot lines, and adventures have kept the story ongoing.Because the One Piece story is so long, its creator Eiichiro Oda has had plenty of room to play around with the timeline and when events take place. There's a time skip that jumps years ahead from one point in the story. But when is it? Here's what we know.When is the time skip in 'One Piece'?According to the One Piece Fandom, the time skip begins at the end of episode 516. Hulu shows this marks the end of season 8. Here, we see Jinbe, helmsman of the Straw Hat Pirates, tell Luffy that they will be parting ways to meet at Fish-Man Island in two years. This leaves Luffy to train with Silvers Rayleigh, the first mate of the Pirate King.Rayleigh begins training Luffy at an abandoned island called Rusukaina. Luffy learns about the three different types of Haki, powers that harness a person's spiritual energy for all kinds of uses. \n\nIn episode 517, the Straw Hat Pirates are back together in Sabaody Archipelago, meeting for the first time in two years.
