Webcomics will often have a separate series of strips featuring characters and/or situations outside of the main storyline. These may be used as FillerStrips, a form of BreatherEpisode, or just SomethingCompletelyDifferent.

Back in the GoldenAge of NewspaperComics, when Sunday comic strips each took up a whole page of the newspaper, they were often accompanied by "toppers", which served much the same purpose, making this OlderThanTelevision.

The "topper" best remembered today is ''KrazyKat'', which originated as a set of strips under the main action in a 1910 strip known variously as ''The Dingbat Family'' and ''The Family Upstairs'' (making it a "bottomer", I suppose, though [[LetUsNeverSpeakOfThisAgain let's all agree never to use that term again]]). [[http://www.toonopedia.com/krazy.htm According to Don Markstein]], Krazy spun off into his (or her) own strip in 1913, while the Dingbats passed from the comics page in 1916.

There are other famous newspaper "toppers" out there in comic history, and YourObedientSerpent is going to wave his wand and invoke the WikiMagic to transmogrify this entry into a more detailed examination of them.

!!Examples:
* ''SluggyFreelance'' has had such B-Side Comics as "Bikini Suicide Frisbee Days" (aka, back in the good old days before plot locked up the characters in specific situations) and "Meanwhile in the Dimension of Pain", drawn by guest artists. The latter actually ended up affecting the main story. It has also has an ongoing side story called "Stick Figures in Space", which is used as filler.
* The Chef Brian, Players and Gamer's Glossary strips in ''CtrlAltDel''.
** In fact, ''CtrlAltDel'' often has a few gag comics between {{Story Arc}}s.
*** And now the "sillies" are in a separate part of the site.
* "PennyArcade" has a few B-Side comics: "Twisp and Catsby" and "The Cardboard Tube Samurai" evolved from strips in the main continuity to their own identity. There was a series of three ([[http://www.penny-arcade.com/2009/6/10/ link]]) treatments of B-Side comics with a poll to determine which gets developed more: "Lookouts", "Automata", and "[[WebOriginal/AcquisitionsIncorporated Jim Darkmagic]]". It was popular enough that both "Lookouts" and "Automata" got additional strips.
* ''Webcomic/{{Megatokyo}}'' does skits featuring the characters in different genres in between chapters, though this really falls under {{Omake}}.
* ''StickmanAndCube'' has "The Adventures Of Captain Invisible" and "Cube's Past Jobs".
* Dead-tree example: ''Comicbook/{{Watchmen}}'' had "Tales of the Black Freighter", which served to metaphorically comment on the main plot.
* ''UserFriendly'' has frequent strips involving caricatures of technology magnates and politicians (and Apple-obsessed aliens), which don't affect the main storylines.
* ''Webcomic/OnePhoneCall'' has its official update schedule as "Tuesdays and whenever I can't update ''[[Webcomic/{{ZeroZeroZeroThisComicAppearsFirstAlphabetically}} 0 0 0]]''".
* ''{{Applegeeks}}'' and its AG-lite.
* ''Webcomic/ElGoonishShive'' has the newspaper-style comics found in ''EGS: NP''; these are sometimes part of the main continuity and sometimes aren't. Regardless, they usually don't tie into the main plot, and are markedly drama-free.
* "Megagamerz 733t" from ''{{Goats}}'' is completely unrelated to the story, save that it is ostensibly [[ShowWithinAShow drawn by one of the characters]], which may in fact lump it in with "Drawn by Billy" sets from ''The Family Circus''.
* The Genie World story from ''Webcomic/TheWotch''.
** Not to mention the arcs where someone takes over the "Wotch HQ" and attempts to run the comic his way.
** Or "The Wotch: Webcomic/{{Cheer}}", an entire spinoff comic based around four of the early transgender characters, in their new lives as cheerleaders.
* ''SomethingPositive'' has S*P 1937/8. One could also throw "New Gold Dreams" and "Midnight Macabre" into this mix.
* ''Webcomic/HeadTrip'' [[http://headtripcomics.comicgenesis.com/d/20060303.html site]] has the adventures of Emo Kid and Chemo Kid, a ''KidHero'' team consisting of a LittlestCancerPatient (also a KnightInSourArmour) and an EmoTeen. Together, TheyFightCrime!
* ''{{SSDD}}'' has two: ''Sticky the Stickman'' and ''Church of Poisoned Minds'', which eventually became their own strips.
* ''Webcomic/GirlGenius'' has a series of radio plays done as podcasts, supposedly in the future but with no clear relation to the plot at present. One has been turned into actual comics.
** There was also the MarySue spoof titled "FanFiction".
* ''ScaryGoRound'' had a brief story about two goblins setting up a detective agency, going to Ireland to recover a pot of gold from a goblin version of Radio/TerryWogan, and mixing it with devil bears. While the goblins do make occasional appearances in the main SGR comic, usually around Christmas, apparently this storyline provoked a great many e-mails to John Allison saying, "I don't get it," and he now thinks he could just have done it with Shelley and Amy instead. It didn't stop him doing another goblins-in-Ireland story-ette a few years later.
* ''VGCats'' has two secondary comics, ''Adventure Log'' and ''Webcomic/SuperEffective'', an RPG "diary" and a ''Franchise/{{Pokemon}}'' parody, respectively.
* After ''[[http://www.drunkduck.com/Tana/index.php?p=638832 Taña, Island Princess]]'' concluded its first volume, its creator started an unrelated story at ComicGenesis called "Get Your Boyfriend Back" (not transferred to DrunkDuck yet).
* ''[[Webcomic/{{Sins}} Sins Venials]]'' had ''{{DDG}}'', updated every time ''Sins Venials''' donation box reached $50. ''DDG'' arguably had a stronger storyline than the main comic. View it [[http://www.sincomics.com/ddg.php here]].
* ''UltimaJava'' has ''If You Believe'', ''Over the Edge'', ''World of Heroes'', ''U-2'' (the series before the ContinuityReboot) and more on the way. ''Over the Edge'' and ''World of Heroes'' have become OrphanedSeries, however — the latter of which recently being moved to the site's forums.
* ''Webcomic/{{Zap}}'' has a side comic, ''Everybody Loves Robot'', written and illustrated by the main comic's writer.
* ''Triquetra Cats'' has its spinoff, ''Polonian Tales''.
* Early ''Webcomic/{{Adventurers}}'' had several BSideComics. Some one-shots, some told an ongoing story.
* ''QuestionableContent'' is occasionally interrupted by 'Yelling Bird', four identical panels of an angry dickcissel, when the author is too busy or unwell to draw a regular strip.
** ... which has since added characters and mutated into something resembling an actual storyline.
* Sunday editions of ''{{Narbonic}}'' are usually some form of these, such as "The Astonishing Excursions of Helen Narbon & Co."
* ''TheLifeOfNobTMouse'' used 'interlude' stories to break up the longer Pie Noon storyline into more manageable pieces. These included ''[[http://www.nobmouse.net/2008/04/14/interlude-doctor-nob/ Doctor Nob]]'', a parody of ''Series/DoctorWho'', and ''[[http://www.nobmouse.net/2007/12/23/the-trouble-with-a-quantum-santa/ The Trouble With A Quantum Santa]]'', which parodied the idea that Santa can deliver presents to the entire world in one night.
* ''{{Acrobat}}'' will post pinups, origins of characters, or short stories in between issues.
* [[DanAndMabsFurryAdventures DMFA]] has ''Abel's Story'', a backstory for one of the characters.
* ''AModestDestiny'' used to alternate seasons of ''The Starship Destiny'' with the main comic. Presumably because new characters and a new setting (scifi as opposed to medieval adventure) gave Sean "Squidi" Howard a break and a chance to shake things up a bit.
* ''UnwindersTallComics'' were at one point interrupted by a {{steampunk}} comic ''Apocalyptus: Thrift and Peril'', which is completely unrelated to the main story. Also at least one character has her own comic on DrunkDuck.
* ''Webcomic/FallCityBlues'' has "Transitfish Syndrome," in which the main characters engage in some [[DadaComics surrealism]], and "Fall City Blues (unframed!)" featuring random gags and filler strips.
* ''Webcomic/{{Shortpacked}}'' features occasional digressions about the author's personal life (usually his trips to conventions), hastily drawn in blue pen and then inked over.
* ''Webcomic/{{Fathead}}'''s Jeff has a recurring [[http://fatheadcomic.com/comics/35/ segment]] which is basically a parody of family sitcoms.
* ''Webcomic/DresdenCodak'' will occasionally tell the story of Rupert and Hubert, two [[QuintessentialBritishGentleman Quintessential British Gentlemen]] who live in a castle on the moon.
* ''Webcomic/AllenTheAlien'' has the filler comic Poorly Drawn Alien, which is very much StylisticSuck.
* ''NewspaperComics/BuzSawyer'' The Sunday strip featured sidekick Rosco Sweeny after they retired from the Navy.
