The anthropomorphic animals in this universe are called "Faunans", because fauna is a colloquial term for the animal life in a place

Sonic grew up in the Christmas Island orphanage starting at age 3 1/2 due to his dad accidentally drowning at sea during a storm they were both in, which laid the groundwork for Labyrinth to give him full blown traumatic aquaphobia

Mighty and Ray became the first two people to successfully catch up to and keep up with the fastest thing alive, leading to the three becoming a trio of little troublemakers

Adding onto the childhood friend angle, the armadillo and flying squirrel are the only people who can call Sonic "Nicky" until Sonic informs Tails of the nickname after Adventure, though the fox keeps it for when they're alone

an 11yo Sonic first went Super as he was falling to Earth after blowing up the Death Egg in Sonic 2, surprising both himself and the 4yo fox piloting the Tornado

The Super Emeralds and thus, the Hyper State are only possible on and above Angel Island, due to the presence of the Master Emerald

Out of all the small animals in the world, Flickys are the most sensitive to Chaos Energy

Combining the previous two, the first person to go Hyper was Mr. Miles "Tails" Prower, sharing the immense energy with four Flickys who followed him and Sonic into the Death Egg

Mania was erased from everyone's memory in a last ditch effort by Heavy Magician to lay in wait to eventually defeat Sonic forever. Her plan worked until (now 12)Sonic got sent into when he was supposed to be 17 and also dead(?), awakening everyone's memories upon finding one of the Phantom Ruby copies Ivo made. This is also why the Present Sonic of the time was able to act like he hadn't been tortured, due to the sudden rush of "Hey wait... I've seen that thing before!"

As I slowly descend into madness from making all this from just wanting to rewrite Sonic Forces, I've added some extra bells and changed some of the whistles. And since I think these deserve more than just a simple mention, they're gonna get quick summaries here.

Amy and her parents live in Station Square, though both Secea and Murve are less than happy with their daughter's habits of chasing a boy and getting into trouble. Her uncle Bramble thinks she's got a better head on her shoulders than her parents over these actions

Cream has 9 sisters(Waffle, Margarine, Frittata, Muffin, Éclair, Scone, and Biscuit, who are all older. Coffee, who's Cream's older twin, and Pancake), though they all live with her dad, whom Vanilla divorced(because Cone specifically singled out Cream and neglected/physically abused her).

After the Metal Virus is cured, Team Chaotix heads off quickly to visit Vector's folks. Vector worries his parents are going to tell him off for sometimes hiding the bills from the IRS with help from Rouge

After the events of Chaotix, Mighty and Ray ended up making a team with up-and-coming fashion designer, Honey. After Neo Metal is stopped and Sonic mentions team names to his old friends, due to coloration, the armadillo, flying squirrel, and cat decide to name themselves "Team Amber"

Super Sonic's quills are a mix of the "standing straight up" and Shadow's. The top three float, the bottom three bend upwards

After the two Storybook games, both Super states(positive and negative) are affected. "Regular" Super Sonic gains the pointed shoes and red forehead gem/possible bindi(like Blaze) of Excalibur Sonic, whereas Dark Super Sonic(which doesn't happen until after Darkspine happens) gains a small lick of fire on the chest(signalling how close the Flame of Judgement was to burning out) and gaining a ring pattern on the upper middle quill and lower side quills. Top has purple, left has red, and right has green, all glowing to contrast again the dark blue, near midnight color the rest of his fur turns

Since she's originally from the Chaos Dimension, Blaze has a Super State outside of Burning Blaze. In reverse, the Sol Emeralds(or how they're going to be called in this AU, the Elemental Citrines) would not work for Sonic

During the Black Arm invasion, Shadow ended up giving some of his blood to Rouge, Amy, Cream, and Big, which gives them minor immunity to the neurotoxin on the Black Comet

Due to being a hive mind of sorts, Black Arms don't have blood types, hence why their blood is much more acidic than Earth blood. Shadow's original donor on the other hand had A- blood. Due to these two factors, Shadow essentially has O- blood

Knuckles first ran into the native Chao of Angel Island at age 2, managing to become fluent in Chaoese. He only learned English(for lack of what language to put) from the Master Emerald(Tikal) in dream lessons

55 years before SA2, Gerald went to Angel Island(This was during an odd period when Angel Island was at ground level, yet not after all the echidnas died. In relation to Knuckles, he hadn't been laid yet), getting the idea to make Shadow a Faunan from the mural in Hidden Palace, as making what looked like a heroic savior of the world would definitely make sure no one ever forgot the name "Robotnik"

Along his hubristic train of thought, Gerald went to Little Planet(because it's a magic satellite that seemingly teleports above Never Lake for a month(I'm pegging it as March) before disappearing for the rest of the year) to get DNA for Shadow's original donor

Like in Sonic Underground, Aleena is Sonic's mother and Sonia and Manic are his siblings, as the three are triplets. However, Manic, as well as the triplet's father, Dewen, are porcupines instead of hedgehogs. Also like in the show, they're royalty, but of the Lune(to contrast against Blaze, who's princess of the SOL Kingdom. In a similar vein, Blaze's dimension's counterpart to Soleanna would be named after the moon)

Also in the vein of making Sonic and Blaze equal yet opposite, this headcanon by knockabiller on DA is canon, with the only caveats being that that Jet is older than Blaze, meaning he's aged up from canon from 14 to 15, and there's a younger sister, who I'm naming Pyre

As for why this dimension is like this? Blame Solaris. Blaze was originally from the timeline created when Iblis was released when the Egg Carrier crashed, born close to a year before Silver as a natural, yet much weaker pyrokenetic. When Silver sealed her and Future!Iblis into another dimension, that caused an entire change in the timeline placing Blaze into the royal family, and making it mirror the Chaos Dimension. Since he was removed from time(though how it went down in specifics is for another post), Solaris decided to entertain himself in Non Existence by removing his counterpart, the moon and space deity Lunorin, from existence as well and started seeing just how "equal but opposite" this could get. Since both aren't the best at understanding mortals(even if Solaris vaguely understood his "death" was meant out of both mercy and necessity), Blaze gets to suffer just as bad as Sonic. This whole thing is based off how Sonic 06 was meant to be set before Rush, with it being Blaze's origins

Metal Sonic isn't powered by an animal. Rather, he's the only Badnik to still be powered by a seed from the Little Planet flowers. One from Stardust Speedway, in fact
