One Piece Omake

Omake (御負け, alternatively おまけ) is a Japanese term loosely meaning extra, popularly used by anime and manga fans to describe standalone bonus material such as concept art or DVD commentaries. Where One Piece is concerned, it almost exclusively refers to the short gag strips that Eiichiro Oda occasionally produces outside the regular manga.

These fall into two main categories:
 * Yonkoma strips, published in special issues of Shonen Jump (and, in one instance, the contemporary databook).
 * Multi-page Strawhat Theater (麦わら劇場) strips, usually published in the series' log books.

Omake strips almost always depict the characters in a super-deformed art style, acting out ludicrous scenarios with no bearing on the canon storyline. Each also contains a preamble from Oda, bemoaning how his editors had "forced" the extra work on him.
