The first change in the animation of One Piece occurs from episode 207, where the aspect ratio changes from 4:3 to 16:9, increasing the display resolution from 640x480 to 1280x720, going from a square to a rectangular size. Covering a broader panorama and improving the quality of the animation.
The anime's resolution changed from 360p to 720p starting with episode 207 and is currently at 1080p and up. Due to the popularity of anime and the emergence of streaming platforms, all episodes were remastered and are currently available in HD, FHD or UHD quality.
All of these animation changes were not exclusive to One Piece, but to all anime in general. Apart from the changes in aspect ratio and resolution, there were other changes that were presented in the anime, such as modifications in the style, art or design of the characters.
When does the animation style of One Piece change?
If we talk about the graphic change, whether in the character design or art style, this occurs from episode 517, which is where the Fishman Island Saga begins. After the TimeSkip that lasted 2 years in the anime's history, Luffy's crew reunites with new appearances, whether due to their physical growth, change of clothes or simply age.
Another change in the style of the characters is seen in the Wano Arc, from episode 890 onwards, the crew's clothing is traditional focused on Japanese culture, where samurai, ninjas, sumos, etc. existed. It also refers to Japanese food, music, dance and history.
In the final part of the anime, which is being broadcast, we see another change in the animation and art style. This occurs in the Egghead Arc, which begins in episode 1086, in this arc Luffy and company wear futuristic clothing that is consistent with the island where they parked.
