aka: Guest Comic
A Guest Strip is a episode of a webcomic that was not drawn or written by the current authors of said webcomic. Due to the communal nature of the Web and webcomics culture, this is much easier to organise than in other media. It is, perhaps, ascended Fan-Art. Usually, guest strips are Non-Canon and posted as Filler Strips. Entire "Guest Strip Weeks" are often invoked by webcomic authors when they need back surgery, a week in Tahiti, an opportunity to deal with familial issues, or a chance to attend a Con. Other comics, usually dailies, post a guest strip on Sundays in lieu of an elaborate Sunday Strip. Nearly all webcomics have done this at some point; it's something of a Necessary Weasel.
- Drowtales uses this to not only lessen the work load on the main artist of the comic, but to use the different art styles to fully show off the current narrative. These strips are just as professional grade as the main comic and just as canon as art done by the main artist, advancing the story along in their absence.
- One special event in the history of guest strips occurred on September 17th, 2007. During the previous month, webcomic author Ryan Estrada drew an entire 48 guest strips for 48 different webcomics - by itself an impressive feat. What's more, he contacted all 48 authors of the 48 webcomics and got them to post each of his guest strips on the same day. So it was that, on a bright sunny morning in September, many webcomic fans woke up to find Ryan Estrada's artwork on dozens upon dozens of their favourite webcomic sites.
- And guess what? He did it again, on September 18th, 2008 - but with 70 guest strips this time. Seventy guest strips. One of those guest strips was for a Comic Within A Comic. One of those guest strips was for a news blog.
- And Shine Heaven Now has never missed a day in part because every break on the author's part is filled with guest strips. This has the interesting effect of limiting the length of any hiatus to the number of filler strips the readership can be coerced to produce.
- Avalon was once advertised in the Keenspot newsbox as featuring "the most comics drawn by other people."
- In the twelve or so year history of Penny Arcade, the need for a guest strip has only come up twice.
- Once was after a PAX convention where the artist came down with swine flu (and then only because he was physically incapable of lifting a pencil to draw). The illness was incorporated into some of the strips.
- Half a year later another was posted, with the explanation "There was a point after PAX East had come to a close and the second leg of our book tour was underway that we began to understand we had fucked up."
- Dinosaur Comics has a guest week once a year or so.
- For some reason Bill The Barbarian has a truckload of these.
- 5 Color Control uses them occasionally.
- El Goonish Shive had a week of them after the Painted Black arc and another after the Birthday Party arc. Dan has done three of them himself for Lit Brick.
- Inverted on The Word Weary: After weeks of asking for guest comics and presumably getting no replies, John Kossler, the author, made three guest strips for himself and posted them under different names. At the end of the week, he admitted as such.
- Femmegasm has had several due to the creator's health problems.
- Even in the Deepest Heart of Chaos... A Glimmer of Order Can Be Found has a lot of these, since any random person can create one, as the comics are an auto-generated selection of photos found on Flickr with captions written by the enterprising author.
- There have been two guest strips in Ears for Elves so far, with the characters but nothing related to the plot. The first was an "exchange" with the artist of Doodling Around, so Naarie also drew a guest strip for that webcomic; the second was a comedy strip by the artist of Sucker Punch To My Emotions.
- Antics by Stephen Gillian has had a few: here, here, here, here, and here.
- The Daily Derp has on two occasions featured fan comics from DeviantArt. There was also a comic drawn by the author's friend and another drawn by Tsitra360 when the author was sick.
- Gunnerkrigg Court did a strange example where the characters made a series of guest strips mutually forming the third installment of "City Face," the surreal adventures of a talking pigeon. Bringing things up to total Mind Screw level, one of the guest strips was done by the author of the comic.
"Today's update was written by me, Tom."
- During the "Party crashers" arc, while Chrispy had a broken finger. The guest artists included Matt Dawson (Sometime Alone), Brooke Eggleston (Also Bagels), Irene Pitcairn (Sun Elves), Robert McConnell, Carl Sjostrand (Ginger's Bread), Terrence and Isabel Marks, John Peters (Gypsygirl Press), and Roman Utkin (who does a Russian translation of Precocious).
- A new set of guest strips began in March 2013, with a couple of twists on the theme.
- As an April Fools joke for 2013, Breakpoint City and Crunchy Bunches switched artists, with Scott drawing Syrup, Up, and Away, and Brian drawing A Normal April Comic.
- Sam Logan occasionally holds O-GAWDs (Obligatory Guest Artist Webcomic Duration), week-long sessions of Sam and Fuzzy strips drawn by a variety of other artists, such as Questionable Content 's Jeph Jacques, or Wasted Talent 's Angela Melick.
- The Whiteboard:
- On this page there's not only the regular strip by Doc Nickel involving a big red Schmuck Bait button, but an additional, related strip by Commander Kitty writer Scotty Arsenault.
- Kathy Garrison of Carry On contributed several strips to hold things over while Doc Nickel was having computer problems, resulting in a week of non-canon strips featuring one of her Carry On characters, who had been given a cameo in this strip. note
- The Comic Strip Switcheroo of April 1, 1997, where 18 pairs of cartoonists drew comics for each others' strips as an April Fools' joke.
- Dilbert had a week of guest strips in 2003.
- Fish Police, while under the publication of Comico, had guest strips in the back called "Fish Shticks". These were still written by Steve Moncuse, but drawn by guest artists.
- Cul de Sac had several weeks of guest strips in 2012, as Richard Thompson was getting treatment for Parkinson's Disease. (Thompson would end the strip later that year.)
- For a week in June 2014, Bill Watterson returned to newspaper cartooning by guesting on Pearls Before Swine
- Fanfic example: The Official List Of Unofficial Rules has rules written by guest authors mixed in.
