''Sea3on'' is an ongoing fan-made webcomic {{continuation}} of ''WesternAnimation/SonicSatAM'', created by the fansite Fans United for [=SatAM=]. The whole comic is based on what details were revealed about the plot of [[WhatCouldHaveBeen the intended third season of the show]].

Picking up from the [[{{Cliffhanger}} ending of the cartoon]], Dr. Robotnik, the EmperorScientist and former BigBad, has been defeated, his Doomsday Project has been thwarted, and the Freedom Fighters are finally ready to take back their world. Unfortunately, [[TheStarscream Snively]] steps up and takes over Robotnik's empire, and [[MonsterOfTheWeek former one-shot villain]] Naugus returns to wreak his own special brand of havoc. The FF, however, are prepared to fight to the end, and are joined (sort of) by Knuckles the Echidna, who has his own agenda.

The comic currently consists of six chapters and four interludes in-between, with a few one-shot jokes here and there. The series can be read [[http://sonicsatam.com/sea3on/ here]].
!!''Sea3on'' contains examples of the following tropes:
* ActionGirl: Sally and Bunnie, in spades.
* AdaptationalVillainy:
** In his single appearance in the original show, Naugus was not outright hostile to Sonic or the Freedom Fighters; he ''did'' use them for his plans, but was more concerned with getting his vengeance on Robotnik. In this comic, however, he is clearly a villain in every sense of the word.
*** Note however this is to some degree accurate to future intentions for the official series, where Naugus was stated to become the BigBad for the cancelled Season Three.
** ''Sally'' plays the lead character in the YetAnotherChristmasCarol mini comic.
** Dirk didn't have much characterization when he appeared in the finale other than being [[HeroOfAnotherStory the leader of another group of Freedom Fighters]]. Here, he's a GeneralRipper CommanderContrarian who [[spoiler:offers one of his own soldiers to Sally simply so that he can have a mole inside the Knothole group.]]
* AndNowForSomethingCompletelyDifferent: A YetAnotherChristmasCarol mini comic with no continuity to the main project was made for Christmas 2012.
* AntiMagic: Knuckles can apparently protect the Chaos Emeralds from being tracked by Naugus' magic through some means.
* BigBad: Naugus.
** BigBadEnsemble: Naugus and Snively.
* BadassLongRobe: Knuckles wears one, complete with a hood.
* BigDamnHeroes: On several occasions, one of the Freedom Fighters, usually Sonic, manages to arrive just in time to save the others from peril.
* CardboardPrison: During the first chapter, "Back to Square One", Sonic, Sally, and Bunnie are imprisoned in a jail cell. Sonic is taken away for questioning, and Sally manages to trick the [=SWATbots=] into letting them go after realizing that Snively [[ManOfAThousandVoices altered their audio receptors to make them think he was Robotnik]].
* CasualDangerDialogue: Sonic, of course. Whether he's being strapped into a chair for (possibly brutal) interrogation or facing impending doom, Sonic always has a wisecrack or two in store for the bad guys.
* ChuckCunninghamSyndrome: Dulcy, though considering [[TheScrappy her status among the fans]], this is probably a good thing.
* ConscienceMakesYouGoBack: In chapter 4, Knuckles gets ahold of the Chaos Emerald and starts to bail out and leave Sonic and co. to deal with Naugus and Snively, but when he remembers that Sally had risked her life to save him from Naugus, he has a pang of conscience and goes back to help.
* DemotedToExtra: Robotnik himself has yet to make a full appearance in the comic, only being mentioned by other characters and seen in {{flashback}}s.
* DimensionalTraveller: Naugus.
* TheDragon: Naugus is initially this to Snively, but soon reveals his own agenda and plans.
* ElementalPowers:
** Unlike the games, the Chaos Emeralds are said by Naugus to have these, specifically the abilities of '''Fire''', '''Water''', '''Wind''', '''Rock''', '''Forest''', '''Light''', and '''Darkness'''.
** Naugus has some elemental magic as well; he's particularly fond of [[AnIcePerson encasing Sonic's feet in ice]].
* EvilCounterpart: The robo-Bunnie from the second short "Me and My Shadow".
* [[spoiler:GenerationXerox]]: [[spoiler:Sally's mother and Rotor's grandfather]] in [[WholeEpisodeFlashback Chapter 5]].
* HoistByHisOwnPetard: See CardboardPrison above.
* HopelessWithTech: Naugus prefers relying on his magic over Snively's techno skills and robots, and considering the latter's track record, it's quite justified.
* HurtingHero: The first interlude, "Waiting is the Hardest Part", reveals that, behind his Gung Ho Soldier[=/=]DeadpanSnarker attitude, Sonic is in fact guilt-ridden and troubled over the various losses he has suffered throughout the fight against Robotnik and considers himself a failure, though he is nonetheless determined to win the war in the long run.
** Sally suffers this twice. The first time is towards the end of the first chapter when she realizes that despite Robotnik being gone, the war isn't over yet, resulting in a brief HeroicBSOD. The second time is at the end of the third chapter when Naugus reveals that [[spoiler:her father is trapped in The Void with Robotnik]].
* HypnoRay: Naugus uses this on both Sonic and Sally to varying degrees of success.
* MacGuffin: The Chaos Emeralds, just like in the [[SonicTheHedgehog games]].
* MechaMooks: Wouldn't be Sonic without 'em.
* NeckLift: Sally is a victim of one at the claw of Naugus.
* NiceJobBreakingItHero: By using the Deep Power Stones to destroy the Doomsday Project, Sonic and Sally caused energy waves to spread all over Mobius and into The Void, allowing Naugus to [[spoiler:use his place-switching spell on Robotnik]] and escape.
* NotHisSled: [[WordOfGod Details revealed about the third season]] stated that NICOLE would eventually be revealed to be a childhood friend of Sally's whose consciousness was trapped in the computer (much like [[ComicBook/ArchieComicsSonicTheHedgehog Archie]] eventually got around to doing). Here [[spoiler:''she's Sally's mother!'']]
* ReCut: Of a sort. There was another ''Sea3on'' comic that was uploaded to the Internet five years before the current version, but that version suffered from a constantly revolving number of artists--many times within the same issue--resulting in very uneven and ever-changing artwork, not to mention a story riddled with plot holes and numerous inconsistencies with the previous TV series. Suffice to say, the original ''Sea3on'' is lost to the annals of the Internet (and for good reason), and the current version of the comic is far superior.
* SixthRanger: Gavin the Bat, who is transferred to the Knothole Freedom Fighters from Dirk's team at the end of Chapter 6.
** [[spoiler:SixthRangerTraitor: He's just there so that Dirk can have a mole inside the Knothole group.]]
* VillainousBreakdown: The stresses of trying and failing to be as menacing an opponent to the Freedom Fighters as his uncle was combined with Naugus' dismissive attitude towards him has [[SanitySlippage eaten away at Snively's sanity]] enough that by the time we first see him in Chapter 6, he's been reduced to a ranting, disheveled figure.
* [[WhatMeasureIsANonHuman What Measure is a Non-Mobian?]]: Rotor goes through this in the short between Chapters 4 and 5, "The Mechanic's Puzzle", with a [[spoiler:[=SWATbot=] he's attempting to repair that's developed sentience and, subsequently, gratitude towards the Freedom Fighter for attempting to repair him.]]
* WholeEpisodeFlashback: Chapter 5 is one told by [[spoiler:Queen Nicole Acorn]] to Sally and Sonic via pre-recorded message on NICOLE.
* WouldHurtAChild: In Chapter 2, Tails performs a BigDamnHeroes moment by tackling an off-guard Naugus when the wizard is about to kill an immobile Sonic. Naugus retaliates by freezing Tails' namesakes in mid-air sending the fox club plummetting to his doom from the top of the in-construction Chaos Eye, [[spoiler:only to be saved by Knuckles in the nick of time.]]
* XanatosGambit: Naugus pulls off one in Chapter 3: Attacking Sally, Bunnie, and Rotor inside Snively's Chaos Eye, he admits to them his dissatisfaction of serving Snively and [[WeCanRuleTogether offers them an alliance]] in exchange for [[spoiler:the safe return of Sally's father]]. Even though the Freedom Fighters refuse, Naugus [[spoiler:doesn't deactivate the bombs they have already placed inside the Chaos Eye, destroying it and forcing Snively to rely on his magic to track down the Chaos Emeralds, just like Naugus originally intended.]]
* YetAnotherChristmasCarol: A separate mini comic was made as a side project to Sea3on, with ''Sally'' playing a WellIntentionedExtremist variation of Scrooge.
