Side-Story Bonus Art

Everything About Fiction You Never Wanted to Know.
Putting the characters in Holiday Dresses is one of the most common themes.

A Sub-Trope of Bonus Material, where artists make what could be described as official Fan Art. They draw scenes of the characters doing things that aren't actually in the work as such.

They could range from Beach Episodes, to Christmas Scenes, to Fashion Shows, to Weddings of the Official Couples, to Alternate Universe settings, to Characters Switching Clothes, to Cosplay Fan Art. Again, it's anything a fan artist might do (that's still acceptable for the rating of the work[1]), just by the actual artists of the work, or people official hired to draw these.

Currently, this is a particularly widespread trope for anime and manga, seen in many online galleries and even in books that are collections of these. Many Webcomics have these as well, often in the form of "voteys" - bonus images which you get to see if you vote for that comic on one of various comic-ranking sites.

While seldom seen today, this sort of material used to be a staple of American Comic Books (primarily in the Romance and Teen Humor genres, or any other comics with a significant female readership.) "Fashion Pin-Ups" showing the characters in different outfits were common, as were reader-submitted fashions—often redrawn by professional artists, with credit to the young designer.

Examples of Side-Story Bonus Art include:

Anime and Manga

Comic Books

  • Some early issues of Elf Quest had cartoons showing the elves living in Poughkeepsie with their creators the Pinis. One of the most telling had them jumping on Wendy Pini's bed early in the morning to wake her up.
  • Fashion Pin-Ups, showing the characters in new outfits (either based on current fashion trends or reader designs) were a common "filler" feature in girl-targeted comics of the Silver Age and Bronze Age. Some typical examples (mostly of the "reader design" type) from Harvey's Bunny ("The Queen of the In-Crowd") comics can be seen in this Flickr collection.
  • Superhero comics occasionally had these features as well. In the early '70s, DC Comics (no doubt realizing that a number of costumes designed in the '40s and '50s looked a bit dowdy by contemporary standards) sometimes showcased reader submissions:

Video Games

  • Advance Wars Dual Strike has some bonus artwork like this, showing the cast in civilian clothes and driving around with a Cool Car.
  • Lots of Nippon Ichi games have this.
  • Just about all of the promotional art for Ace Attorney are such works.
  • Any game with unlockable bonus costumes could be said to be indulging in this, perhaps most famously Kratos going from a half-naked god-killing badass to... a cow.

Web Comics

R.K.Milholland:Here's a fun game! Seeing how all the characters are based (closely) on real people whom I call friends, start a deadpool to guess which of them will be the first to kill me for the swimsuit issue.
