Language: The language in One Piece is relatively mild compared to other shows with a similar rating. However, some profanity is used, though it is not prevalent. Sexual Content: Sexual situations are rare in One Piece. There may be affection or innuendo, but they are seldom explicit.

However, as any fan of the show knows, One Piece is filled with violence, blood, and mature subjects, all things that 4Kids didn't want their audience to see. Thus, the show censored various scenes and even cut entire arcs and characters from the show.
