* CreativeDifferences: Penders vs. Bollers got so bad, it ended with them ''both'' leaving the comic simultaneously. Which is why we have Flynn... whose works Penders steadfastly neglects to read, but swears to chuck in the {{Canon Discontinuity}} bin if he's ever re-hired. As of recent events, though, Penders returning is ''quite'' unlikely.
** According to Penders, the editor of the comic forced him to bail because [[ExecutiveMeddling he kept on changing his stories]], the final straw being the Mobius: 25 Years Later story. Of course, seeing as Penders has devolved into ItsAllAboutMe and NeverMyFault, it's hard to tell if this is true or not.
* CreatorBacklash: The shipping wars got so bad that Ian has essentially sunk Sonic/Sally as a pairing with the soft reboot.
* CreatorsFavorite: Writers of both ''WesternAnimation/SonicSatAM'' and ''ComicBook/SonicTheHedgehog'' have admitted that Princess Sally Acorn is their favorite character. Though she has more than a few detractors that could lean her into CreatorsPet territory, she has almost as devout a number of fans, making her a BaseBreaker at worst.
* ExecutiveMeddling: A large source of fan frustration. Sega doesn't like their characters getting hitched, for example, so you'll rarely see any romance with the video game characters after 2006 or so. Some game characters had parents in the comics but rarely addressed them as such due to editorial and company mandates, usually being cut off (for example, "My m-"). [[VideoGame/SonicRushSeries Eggman Nega]] has yet to make an un-obstructed appearance due to hang ups with Sega.
** Part of why Knuckles and the echidna race had so much build-up back in the day is that [[http://www.kenpenders.com/forums/viewtopic.php?f=5&t=2686#p56057 Sega]] vetoed ideas that were originally meant for Sonic, yet went through with no problem when applied to Knuckles.
** Due to a lawsuit between Archie and former writer Ken Penders, the characters he created were abruptly removed from the book in the aftermath of the Genesis arc. It's most noticeable in issue #244 where every echidna character Penders created was moved to another dimension. ''Off-screen''. This led to a major case of AbortedArc; many of the affected characters were integral to ongoing story arcs.
** And there's Sega's [[ScrewedByTheLawyers legally obligated mandate]] that keeps characters and elements from all of the non-western non-game Sonic continuities (I.e. ''Anime/SonicX'', ''Anime/SonicTheHedgehogTheMovie'') [[ExiledFromContinuity from ever being used in the comic]], owing to tangled copyright issues between Sega of Japan and Sega of America, as well as the companies that co-produced those other series, including the animation studios Creator/TMSEntertainment and Creator/StudioPierrot respectively, ''Sonic X''[='=]s current American distributor Creator/SabanBrands, and ''Sonic the Movie''[='=]s defunct licensor Creator/ADVFilms[[note]]Meaning ''Sonic the Movie'' is still floating in American anime licensing limbo, not having been rescued yet[[/note]].
** Likewise, elements created specifically for the Archie Sonic comics (and by proxy, it's precursor ''[=SatAM=]'') are not allowed to be used in other Sonic continuities due to the aforementioned legal embargoes. The closest exception was cameos of ''[=SatAM=]'' and ''Adventures of Sonic'' characters in ''VideoGame/SonicSpinball'', which was a western produced Sonic spinoff to begin with.
** Another odd mandate is that the writers are unable to call Mobius "Mobius" anymore (it's now referred to as "Sonic's World").
** The idea of Metal Sonic being a [[LegacyCharacter series of robots]] [[FlatCharacter devoid of personality]], rather than one individual recurring robot, [[VillainDecay and being much easier to defeat than the canon Metal]], was eventually nixed by Sega, who got tired of it and told Ian Flynn to cut it out. Surprisingly, this is one of the few changes that was met with positive reception from fans, due to Metal actually gaining a personality and becoming a much bigger opponent than before.
** As of the reboot, every non-Sega, [=SatAM=], [=AoStH=], and Ian Flynn character [[PutOnABus has been removed]] until further notice. While he hints that he can use ''WesternAnimation/SonicUnderground'', using those like Manic and Sonia without their in-series background of being Sonic's siblings, mostly because he knows the fandom would get up in arms.
** Ian originally wanted the arc leading up to Issue 250 to be about the Freedom Fighters rescuing Sally with her being de-roboticized in the milestone issue. However, due to the ''Worlds Collide'' crossover, these plans were aborted and Sally was returned to normal thanks to the reboot.
** Yet another mandate prevents the Genesis-era versions of the game characters from being used as their younger selves.
* ExiledFromContinuity:
** All of the 170+ characters created by writer Ken Penders have been [[PutOnABus permanently removed from the series]] due to a major lawsuit with him, including several major characters and series mainstays.
** While Eggman Nega technically does exist in the Archie series, he is not allowed to make an unobstructed appearance or even be fully ''named'' (only being referred to as "Doctor Nega") because of unexplained hangups with Sega.
** Due to messy legal issues involving Sega of Japan and Sega of America's separate copyrights on the numerous Sonic properties, as well as copyright hang ups between other studios that co-produced certain Sonic series (I.e. animation studios Studio Pierrot and TMS Entertainment, and American distributors such as the now-defunct A.D. Vision and the now-defunct Creator/FourKidsEntertainment and the currently active Saban Brands), Sega gave an editorial mandate that unique material or characters from any Sonic continuities outside of the video games, the ''WesternAnimation/AdventuresOfSonicTheHedgehog'' and [[WesternAnimation/SonicSatAM SatAM Sonic cartoons]] (which the Archie comics were directly based on and always borrowed elements from) and ''WesternAnimation/SonicUnderground'' are not allowed to be used in the comic. This ended up biting Archie in the rear hard when they had unauthorized cameos of characters from ''Anime/SonicTheHedgehogTheMovie'' in issue 101, which earned them a hell of a dressing down by Sega. ''Anime/SonicX'', which is another continuity that the comics are not allowed to borrow from, once had a [[ComicBook/SonicX 40 issue comic tie-in]] produced by Archie, and a one issue cross-over with the main comic universe, to the point that Sega has forbidden reprints of the ''Sonic X'' comic at all.
** Likewise, elements created specifically for the Archie Sonic comics are not allowed to be used in other Sonic continuities due to the aforementioned legal embargoes.
* FanNickname: The "Nu252," for [[CosmicRetcon what happened to Sonic's world after]] ''ComicBook/SonicTheHedgehogMegaManWorldsCollide,'' the fact that it starts in the 252nd issue, and the ''[[{{ComicBook/New52}} New 52]]'' reference. The ''Mobius Encyclopaedia'' wiki also gives it the name "post-Super Genesis Wave", akin to the PostCrisis timeframe.
* HeyItsThatGuy: More like Hey, It's that Artist. The gal who draws the web comic [[Main/GhostsOfTheFuture Ghosts Of The Future]] has done a few stories here and there starting with issue 231
** In addition to the above mentioned Evan Stanley, another fan artist known as Dawn Best was also responsible for line work in several issues of the comic as well.
** Another fan artist, J. Axer, also did a bit of work for the comic as well.
** Dan "''ComicBook/SuperiorSpiderMan''" Slott did a few issues for the comic as well, specifically the Zone Wars stories.
** Tyson "Rittz" Heese, known for his comic ''WebComic/BoxerHockey'', got a few issues under his belt as well.
* KeepCirculatingTheTapes: Averted. Despite fears of the result of ScrewedByTheLawyers down below, Archie is still releasing reprints of the old issues.
** That's not to say there aren't straight examples, though. The Sonic/Image crossover is unlikely to be reprinted, and so is the first story in ''Sonic Live''. Of course, these two stories were poorly received anyways.[[note]]The former due to it being a BackDoorPilot for Ken Penders' failed creator owned series (the villain of which was supposed to be the figure in Knuckles' ultimate destiny), misrepresenting the Image characters, and making the Sonic characters fictional in a reality. The latter due to the use of photos & characatures of real life children (Ken Penders' son & niece), an IdiotPlot, aexplicit statements the Sonic characters were fictional in an attempt to mimic [[Film/LastActionHero the Arnold Schwarzenegger movie of "similar" name]], and having the gall to state that Sonic's creation was mostly due to two white Americans with Yuji Naka being vaguely referred to as a "staff artist".[[/note]]
* OldShame: Jonathan "WB" Gray, one of many a PromotedFanboy, absolutely regrets being the guy who drew "The Slap"
* PromotedFanboy: Several examples, most prominently current head writer Ian Flynn who was known as the author of a popular fan comic [[http://www.bumbleking.com/forum/viewtopic.php?p=63855#63855 Other-M]] before getting hired as head writer.
* RecursiveAdaptation: The comic had already started to incorporate some plot elements from ''SonicChronicles'', which itself had seemingly borrowed and modified some of its echidna lore material from the comic.
* ScrewedByTheLawyers: The ongoing lawsuit by Ken Penders has possibly led to the vast majority of the cast up and disappearing (too early to confirm, though). This is also telling in issue #243-244 where one comic ends with Sonic fighting Lien-Da and the rest of the Dark Egg Legion, then the next panel as Sonic [[AllJustADream coming to after being knocked out]] and [[{{Lampshaded}} asking where everyone went]]
** As of #252, it seems that the entire universe has soft rebooted, with 256 establishing that the whole ''multiverse'' has been rebuilt: select characters like Sonic, Blaze and Eggman remember the original universe; others, like Naugus, remember them as vague memories; and there's those like Nu!King Acorn, who has absolutely no memory of the old world. The new universe has completely overwritten the old now, though, including memories, so the old world is now completely gone.
** The aforementioned embargo on using characters or elements from series like SonicX due to copyright issues.
* ShrugOfGod: When asked about the fate of Robotnik's parents, Flynn posted two ideas. One was that Robotnik [[SelfMadeOrphan "did away"]] with them. The other was that they migrated to the United Federation. In either case, the writer leaves it up to the reader.
** With the recent reveal of ''WesternAnimation/SonicBoom'', there have been questions asked as to if this would be incorporated into the comic in anyway. So far, the only answer has been "No comment." Eventually it was revealed that Archie was doing a separate ''Sonic Boom'' comic to tie in with the TV series and video game. Similar to what they did with ''Sonic X''.
** While Ken Penders' characters can't be used, there has been no comment on whether or not characters from other writers (besides the current team) can make an appearance now, though it seems it may not be the case. Also, while Scourge was technically introduced by Penders as Evil Sonic, whether or not being an evil version of Sonic means he can still appear is unknown even by the current writers. However, due to Ken claiming that [[DisneyOwnsthisTrope he created the concepts of evil Sonics and a multiverse for the comics]], Archie's not going to have either to avoid any more legal issues. This is most likely why Sticks the Badger is the only ''WesternAnimation/SonicBoom'' representative in the upcoming ''ComicBook/SonicTheHedgehogMegaManWorldsUnite'' storyline.
* WhatCouldHaveBeen: The original plot for "Endgame" really did involve Sally's demise -- her apparent restoration later on was to have been a robot double, the truth only slowly coming out later as "Sally" began to act increasingly suspicious and out-of-character.
** Ken's [[http://www.kenpenders.com/forums/viewtopic.php?p=50843#p50843 stated]] that some of the original ideas for the Princess Sally miniseries included a roboticized Queen Alicia ruling over her own subjects as a threat to both the Freedom Fighters and Robotnik. Another was a Thelma and Louise type story with Sally and Bunnie. Sega vetoed both of these ideas, wanting to use only Sally and Robotnik. This is what led to the Substitute Freedom Fighters and Geoffrey St. John.
*** [[http://www.kenpenders.com/forums/viewtopic.php?f=8&t=2586&start=50#p51279 Regarding]] the Source of All, one of the ideas that Ken was brainstorming with a friend of his was that the Source was actually an AI made out of a pool of nanotechnology, from either the past or the future, that was so advanced as to be indistinguishable from magic. However, they never figured out what it's motives were before it was nuked.
** Both [[http://archive.sonichq.net/newsite/comics/kbsonicoverview.php Karl Bollers]] and [[http://www.kenpenders.com/forums/viewtopic.php?f=5&t=122 Ken Penders]] have made public their plans for the comic had their employment at Archie continued.
** Ian Flynn originally intended to have E-123 Omega off Tommy Turtle, but ExecutiveMeddling had that changed to the Egg Fleet. In fact, ExecutiveMeddling kept Omega from appearing in the comic for some time since Karl Bollers tried to put him in. It wasn't until issue 3 of ''Sonic Universe'' that he made an appearance.
** One of the biggest cases of this was the Endangered Species arc. Part one had font that was obviously put in at the last minute to keep from referring to certain characters by name, while the rest was completely rewritten to remove them altogether. The arc was controversial at best as a result.
** Everything outlined [[http://www.bumbleking.com/forum/viewtopic.php?f=4&t=7231 here]].
*** Ian's already given a little bit out: [[spoiler:Endangered Species was originally planned to have a ''happy'' ending.]]
** Flynn has also [[WordOfGod gone on record]] to say that the early implied romance between Tails and Barby Koala (of the Downunda Freedom Fighters) is "completely one-sided and [[{{Shotacon}} kind of creepy]]", (most likely due to the age difference, with Tails being around 11-12 and Barby appearing to be in her late teens) and that as long as he's on the comic it's not going to happen.
** Currently, Ian Flynn is writing essay known as the "Lost Hedgehog Tales," which will explain his original plan for the series, before the Ken Penders lawsuit, leading up to issue 200.
** Ian Flynn really wanted write a conclusion to Sonic Underground, but ExecutiveMeddling always got in his way. He came close to being able to release the story in the fiftieth issue of Sonic Universe, with official promo art even being released, but those plans were nixed in favor of writing a lead up story to ''[[ComicBook/SonicTheHedgehogMegaManWorldsCollide Worlds Collide]]''. And thanks to the CosmicRetcon destroying the series' multiverse, the chances of the story ever being released are unlikely. However, Ian Flynn intends to include the story among other scrapped story plans in the Lost Hedgehog Tales.
* WordOfGay: Ken Penders got around the CCA somehow by hinting at one of the characters in the "Mobius: X Years Later" storyline being gay... and somehow doing this while showing the life partner, threading the relationship into the text. Once fans started searching, it became obvious (and confirmed by Ken), that the hinted couple was ''Rotor and Cobar'', the latter an echidna scientist from ''the Dark Legion''.
* WordOfGod:
** Current writer Ian Flynn has organized his own message board, where he and other creators interact with fans and answer their questions. His predecessor, Ken Penders, also kept up a message board while he was writing for the comic, which is still active and occasionally talks about the stories that he had planned for the series.
** The events of ''VideoGame/SonicTheHedgehog2006'' occurred in the comic as they did in the game, including the CosmicRetcon. Soleanna has been mentioned a few times and issue #246 has a brief appearance of White Acropolis. ''The Complete Sonic Comic Encyclopedia'' describes it in more detail, including entries on [[http://sonic.wikia.com/wiki/Iblis_%28Archie%29 Iblis]], [[http://sonic.wikia.com/wiki/Mephiles_%28Archie%29 Mephiles]], and [[http://sonic.wikia.com/wiki/Solaris_%28Archie%29 Solaris]].
