History Characters / SonicTheHedgehogGroups

** As it turns out, under the leadership of Pachacamac's mother, they were fairly chill and peaceful, though maybe they were MartialPacifists, but when she died and her son took over, the Knuckles Clan became this trope.

* BloodKnight: The Knuckles Clan echidnas are express their love for fighting.

* '''Lightning Wispon''': Allows the Avatar the powers of the Ivory Lightning (which is more akin to the [[VideoGame/SonicAdventure Light Speed Dash/Attack]]) and gives them a [[ShockAndAwe lightning]] [[WhipItGood whip]] to attack nearby foes.

* FrameUp: Some believe that this was their true motivation of arresting Sonic in ''VideoGame/SonicAdventure2'', in order to cover up the existence of Project Shadow and, by extension, the ARK massacre, and are playing the news networks honestly mistaking Shadow for Sonic to their advantage.

* KarmaHoudini: We haven't seen if they suffered any real consequences for the Space Colony ARK massacre.

* ChuckCunninghamSyndrome: Aside from the return of the infamous G.U.N. truck in ''VideoGame/SonicGenerations'', the organization has not had a major appearance since ''VideoGame/SonicTheHedgehog2006''. [[spoiler: [[Film/SonicTheHedgehog22022 Not in videogames, at least]] ]]. This is due to director Takashi Iizuka wanting to keep the focus off human characters other than Eggman. That being said, the military vehicles Eggman and Sonic deal with in Cyber Space during ''VideoGame/SonicFrontiers'' are directly stated by Eggman to belong to G.U.N., but the vehicles are unmanned drones and a figment of Sonic and Eggman's memories, anyway.

* HeroAntagonist: They served as one to Sonic after mistaking him (or perhaps, [[FrameUp "mistaking"]] him) for stealing a Chaos Emerald. Even in ''VideoGame/ShadowTheHedgehog'', their forces will attack Shadow no matter what side he chooses (though this is more because their commander has a personal vendetta against him).

* KarmaHoudini: They never suffer any real consequences for the Space Colony ARK massacre.

** Outside of videogames, [[spoiler: the version of G.U.N. that appears in the [[Film/SonicTheHedgehog22022 2022 movie]] is first introduced as antagonistic towards Sonic, capturing him along with Tails, but when their commander is informed that [[BiggerFish Robotnik]] could possibly be back, he takes the news very seriously and clearly considers him to be the bigger threat. Also, unlike their seemingly more TriggerHappy videogame counterparts, the agents involved in Sonic's capture only used non-lethal weapons and even then they still made sure to give their human targets a warning instead of shooting on sight. Once it's clear that Robotnik is indeed back, and more dangerous than ever, they drop their pursuit of Sonic entirely and even help Tom and Maddie get back to Green Hills despite them previously interfering with their mission, making the movie version of G.U.N. an amalgamation of their characterization from ''VideoGame/ShadowTheHedgehog'' and ''VideoGame/SonicTheHedgehog2006''.]]

* NoBiologicalSex: Chao are a primarily genderless species, and, in game mechanics, any Chao is capable of producing an egg with any other Chao, suggesting absolutely no sexual dimorphism whatsoever. However, some games do refer to some Chao with gendered pronouns, such as siblings Cheese and Chocola. That said, recent media has switched to using [[GenderNeutralWriting "they/them"]] pronouns for the two Chao, and the species in general, to emphasize this trope.

* GenderNeutralWriting: All instances of individual Ancients are referred to exclusively with "they" or "them", with the same courtesy applied to the Koco, regardless of TertiarySexualCharacteristics. Considering they're aliens, it's possible they may not have a gender.
** The Chao, their descendants are cannonically {{Hermaphrodite}}s who are each capable of reproduction with any other adult-stage Chao and the [[AllThereInTheManual concept art]] implies that the Ancients were only considered to have a gender [[BizarreAlienSexes during certain stages of their lifecycle.]]

* FrameUp: It's believed that this was their true motivation of arresting Sonic in ''VideoGame/SonicAdventure2'', in order to cover up the existence of Project Shadow and, by extension, the ARK massacre, and are playing the news networks honestly mistaking Shadow for Sonic to their advantage.

Even in ''VideoGame/ShadowTheHedgehog'', their forces will attack Shadow no matter what side he chooses (though this is more because their commander has a personal vendetta against him).

* CharacterizationMarchesOn: When first introduced in ''VideoGame/SonicAdventure2'', G.U.N. is portrayed as being completely ruthless with absolutely no sympathetic qualities. Their raid on the ARK triggered the the events of the game, they relentlessly hunt down Sonic without even attempting to hear his side of the story, and show what seems to be zero concern over any of the potential collateral damage they're causing during their pursuit of him. Come ''VideoGame/ShadowTheHedgehog'', they're shown in a much better light, as while they still antagonize Shadow, they're shown to have the planet's best interest at heart and bravely fight off the Black Arms' invasion. By ''VideoGame/SonicTheHedgehog2006'', they're portrayed as being completely heroic and are nothing but helpful to Shadow and his allies.

** In ''VideoGame/SonicAdventure2'', where GUN are a colossal nuisance at best, abduct Sonic without explanation no less than twice, and in the backstory [[spoiler:shot Maria Robotnik, murdered the entire civilian population of the ARK, and later executed her grandfather after forcing him to make weapons for them]]. That said, Eggman and Shadow paint them ALighterShadeOfBlack, since their plans for the Eclipse Cannon have a much higher bodycount than anything GUN is responsible for.

* BenevolentArchitecture: They are greatly implied to be the reason Sonic's world is covered in beneficial and convient grind rails, springs, and loop-de-loops. One of the objectives in ''Frontiers'' is activating the technology they used to grow them from the ground.

** The Hero Chao were almost immediately outdated; while they have a direct association with the heroic characters of the franchise, the same can be said for the standard, iconic, neutral chao, leaving the Hero chao redundant past their status as a branch of EvolutionPowerup. Even in ''VideoGame/SonicAdventure2'', MiniMe Chao of Sonic and [=NiGHTS=] were the result of raising Neutral, not Hero, Chao.

* EverythingsBetterWithPenguins: Pecky.

* BreakoutCharacter: The Chao was a huge reason why people got into the modern Sonic games of the 21st Century. So much so that they are seen as the main species mascots of the franchise like the mushrooms/toads of Mario. Unlike Originally Flicky and the other animal friends.

-> '''Debut:''' ''Videogame/SonicFrontiers''

* WaddlingHead: They're stone balls on little legs. [[spoiler:Originally, those bodies were their cores as Ancients.]]

* WasOnceAMan: As revealed in ''VideoGame/SonicFrontiers'', [[spoiler:they used to be the Ancients, a benevolent alien race that fled to Earth after their home was destroyed by the malicious being known as [[EldritchAbomination The End]]. After the planet destroyer found the survivors again, a small contingent of survivors fled to what became Angel Island, and steadily devolved overtime into the Chao we know today. Chaos, being a former Chao, is the only one who is known to have regain some of its Ancient heritage]].

An advanced alien race that lost their homeworld and were nearly driven to extinction due to an EldritchAbomination known only as The End. They were the original owners of the Chaos Emeralds and were guided to Sonic's world by their resonance with the Master Emerald, settling on the Starfall Islands and starting development on technology that could put a stop to The End - but it proved far too powerful for them to destroy, so their only solution was to repurpose some of their technology to serve as an archive for their history and culture for future generations to uncover. Before being wiped out by The End, they utilized Cyberspace in order to seal away their own essences into vessels called the Koco, and during their last stand against their enemy managed to seal it within Cyberspace as well.

* ContrastingSequelMainCharacter: Compared to previous games' precursors, who caused the plots of their games through selfish needs ([[VideoGame/SonicAdventure Pachacamac]] trying to gain power from the Chaos Emeralds out of greed, and the [[VideoGame/SonicTheHedgehog2006 Duke of Soleanna]] messing with time travel out of a desire to see his wife again), the Ancients were victimized by the GreaterScopeVillain, The End, and were forced to leave their planet when it got destroyed, making them more tragic.
* DoomedHometown: Their home planet was wiped out by The End, and their society on the Starfall Islands didn't fare much better.
* FlingALightIntoTheFuture: The Ancients lost their lives and their homeworld fighting The End but they left the Chaos Emeralds on Earth in the hope that someone can bring down the eldritch planetoid once and for all.

* GreaterScopeParagon: Their home planet was, as far as can be told, the original resting place of the Chaos Emeralds, which act as the central {{MacGuffin}}s in most games in the series. Sonic, of course, has used the Emeralds time and time again to defeat the villains threatening his planet, but it goes ''way'' beyond that -- several other factions and entities have made use of the Chaos Emeralds the Ancients brought with them to positive ends. [[ForWantOfANail Without the Chaos Emeralds,]] Gerald would have been unable to give the Eclipse Cannon the power it needed to defeat the Black Arms; there would be no way for Sonic and friends to travel between their world and the Sol Dimension to help out or be helped out by Blaze; Perfect Chaos would have been impossible to stop or contain by Tikal; and so on. In fact, the space rocks brought in by the Ancients end up being so ''vital'' to the planet's existence that they're a key aspect of the cycle of destruction and rebirth that Dark and Light Gaia represent -- the world would only end up destroyed if Light Gaia did not have the Chaos Emeralds to fuel it. The only part of the Chaos Emeralds' equation left unexplained is their relation to the Master Emerald, as the Ancients seemingly weren't aware of its existence until its energy began pulling them towards Sonic's world.

* DeadAllAlong: [[spoiler:The first time Amy sees some Koco move on to the afterlife, she's under the assumption that they just died in front of her and is appropriately distraught. It's not until later on that she and the others find out that they're the remnants of the long-deceased Ancients.]]

* SoulJar: [[spoiler:They are what remain of the Ancients who could not pass on completely.]]
* UnfinishedBusiness: [[spoiler:Many Koco's requests for Sonic allude to a task that they were unable to complete towards the end of their lives as Ancients. Once they're at peace, their souls are able to pass on, leaving behind their stone vessels as inanimate husks.]]
