I keep going down these rabbit holes I shouldn’t go down BUT! Although this theory is one that I don’t fully believe in (unlike the infinite/solaris theory and the chaos emerald theory) I still have a good argument that I want to talk about very bad.
I also tried to make this as short as possible but there’s a lot of ground to cover, but at least it’s not the infinite/solaris theory. But I have a TLDR at the end.
[Spoiler Warning for Sonic and the Black Knight]
let’s start with a ✨numbered list✨
1. Blaze the Cat
Blaze is the biggest caveat for this theory, but I think it’s best to start with her.
Now, firstly I need to clear up some things.
[Eggman: My world...]
[Eggman Nega: and my world...]
[Eggmen: are in a manner, inextricably linked!]
[Blaze: Like two Eggmans?]
Part of the Blaze’s world is that it’s a parallel universe. Parallel Eggmen, Parallel emeralds, Everything else that isn’t stated outright. Like how Tails and Marine are definitely counterparts. Seeming as Tails came from South Island and Marine came from southern island, Tails is definitely based on a kitsune and Marine, in theory, based on a tanuki.
And, although not stated completely, Blaze and Sonic are universal counterparts.
[From Sonic Wiki: Blaze was designed as a charater who was equivalent yet and alternate version of Sonic’s character.]
Much like the Sol and Chaos emeralds, Sonic and Blaze are a mirror version of one another, although slightly different.
Alright, now that we have that out of the way:
Looking at the connections between the others, Sonic and Blaze seem, a bit too different.
The Sol and Chaos emeralds fulfill the same role, although their different appearance, and have a similar story.
Tails and Marine fulfill the same role, although their different appearance, and have a similar story.
The Eggmen fulfill the same role, although their different appearance, and have a similar story.
Blaze and Sonic fulfill the same role, although their different appearance, and have a... completely different story.
Blaze was born to a royal family, and set to protect the Sol Emeralds and the Jeweled Scepter as her birthright, and it’s somewhat hinted that her powers may also be a birthright. Sonic, on the other hand, has no known past, and seems to have just run into the Chaos Emeralds by accident.
You could claim that Blaze does take on the role of both Sonic AND Knuckles, which is fair and stated on the wiki, however Knuckles is also never stated to be any kind of royalty, and certainly doesn’t have that kind of past, his past being one of the more tragically alone ones.
And here’s something interesting.
Time has warped our vision of Blaze. We all know her as “Princess Blaze the Cat.” But from watching Sonic Rush, her opening game... she is never mentioned to be a princess until the very end.
[Burning Blaze: As princess, it is my duty to protect the Sol Emeralds...]
From what I remember, this is the FIRST mention of her royal status.
From this game’s viewpoint, they reveal the mirror status of the dimensions. They then show both Blaze and Sonic having mirror super transformations using their emeralds, highly implying that Sonic and Blaze were mirror versions. (also this was implied already by just Blaze’s shoes.) and then it’s revealed that Blaze is royal, and a princess.
So if she’s the mirror of Sonic, what does that mean for Sonic? Especially right after showing the two of them being, well, mirrors.
2. King Arthur
SATBK is much less transparent about the counterpart universe thing.
Now this is an alternate universe, set up by Secret Rings, and surprisingly not just a story Sonic told as an elaborate excuse.
They don’t hide obivous Sonic characters being put into roles, and their in these roles for a reason.
Blaze and Silver as Percival and Galahad, the knights who quested together for the holy grail.
Knuckles as Gawain literally only because of “Gawain and the Green Knight” But I respect that so much.
Jet as Lamorak because of Lamorak’s fiery temper and competitiveness.
Shadow as Lancelot because he’s the “closest knight to the king” stated in game (👀)
Tails as a Blacksmith because that’s p much the medieval version of a mechanic.
Amy as the Lady of the Lake because like. Fuck she’s the most powerful one there. (but seriously, in forces she’s shown to be the most level headed leader and strangest, especially in Sonic’s absence. As well as “sensing” that he was still alive and having a past in tarot.)
And Merlina as Merlina because... well that’s a whole other theory.
(all my theories are being brought up in the post. like i know the first two were expamples of theories I fully belive in but damn this is like a avengeners, ok,)
But Sonic as King Arthur makes sense when it’s revealed. Although he wasn’t anyone’s counterpart in Secret Rings (because secrets rings was confused as hell) He is in this game, and as the ring leader of everyone following him in SATBK, it makes sense.
Although something that was never brought up...EVER is the Knight’s backstories, which are EXTREMELY important not only in Arthurian legends, but for the knights in Sonic lore. All of the knight’s mentioned backstories are important to their character, in both contexts. Although their never brought up.
*DEEP BREATH* Alright. The similarities between Sonic Character/Knight backstories.
Shadow and Lancelot have pretty simmilar backstories when getting down to it. Shadow/Lancelot were both raised for greatness, but still outshined by Sonic/Arthur. Although remaining loyal to them, even if for Shadow it’s only in times of need. Shadow doesn’t want to admit he’s a supporting role to Sonic, although Sonic generations kinda throws that Idea out of the water when Shadow cheers Sonic on while watching from the sidelines, much like early Lancelot.
For Blaze and Percival, in multiple interpretations Percival is of noble birth. Upon meeting Sonic’s Gang/The Knights, Blaze/Percival get’s inspired by their heroics and eventually joins them.
“Lancelot and Percival prove morally superior to Gawain who follows the rules of courtliness to the letter rather than the spirit.“ Is an actual quote from Wikipedia. Although it is VERY hard to find a concrete backstory for Gawain other than “separated from his home”, I think this proves enough. As well as the Gawain and the Green Knight story (in which Gawain tries to slay the green knight and then he picks up his head and says “see you in a year” is pretty representative of Knuckles constantly breaking the master emerald in a comedic light.)
Lamorak/Jet are known for challenging Arthur/Sonic to competitions.
Galahad/Silver are searching for an object/person aided by Percival/Blaze
So now that we’re all good, do you see the similarities between part one.
Although everyone else has given backstory similarities, Sonic is given none, seeming as, as far as we know, Sonic HAS no backstory.
But isn’t it interesting that King Arthur’s backstory is being lost royalty? And the secret son of the king? Wack.
3. Sonic Fucking Underground
Now, most of you are probably unfamiliar with Sonic Underground. Good.
If you’re not, you watched it as a kid and you’re nostalgic, and let me tell you I watched the entire show recently and it’s not as good as you remember.
But Sonic Underground’s quality and history could be a post on it’s own, it doesn’t matter here. What matters is the plot:
[From Sonic Wiki: Sonic, Sonia, and Manic are the children of Queen Aleena, the rightful ruler of Mobius and are pursued relentlessly by Doctor Robotnik and his bumbling bounty hunters sidekicks, Sleet and Dingo. As infants, the siblings were separated and placed in hiding to fulfill a prophecy made by the Oracle of Delphius (a spoof of the Oracle of Delphi of Ancient Greece) that the triplets would grow up to find their estranged mother, overthrow Robotnik and take their places once more as Mobius' rightful rulers.]
FORGOTTEN ROYALTY YOU SAY.
Now, Sonic Underground is VERY SEPARATED from Sonic Lore, and nothing has ever taken from it besides Manic appearing in some comics, although from what I know he’s never mentioned to be Sonic’s brother. So This is the part I always take with a grain of salt, however;
4. In conclusion/TLDR
We have Two Instances of Sonic being lost Royalty (One in a separate reality and one in a separate continuity)
We have Two Instances of Dimentional Counterparts of Sonic being Royalty (Blaze and King Arthur)
We have zero given backstory for Sonic
We have Three instances of Sonic, or a counterpart, being royalty
And from what I remember hearing, three’s a pattern.
I've been playing Fire and Ice on my 3DS, and I reached this area called Gothic Gardens. Now, Shadow isn't in this particular game (at least, not so far), and I've never heard anything about the Black Arms in the Boom universe, or whether Shadow's origin story is the same in Boom as in canon.
But check this out:
I grabbed this screenshot off the wiki. The wiki page only mentions this in passing, but you can clearly see the Black Arms logo.
I'm not finding anything else in the wiki or on Google about Black Arms in Boom, but maybe I'm just not using the right search terms.
So for the moment, I'm going with the assumption that the Black Arms are canon to the Boom-iverse. I'm guessing, then, that Shadow is still partly Black Arms, whether or not he was made in a lab (since there's been no mention of Gerald, yet, but Eggman has mentioned his father, who was apparently also named Eggman).
But, anyway, here's my theory:
The Black Arms symbol in canon is usually either black or red against either a black or white background. But on these banners, it's gold against a red background. Further, this zone appears to have been built by either humans or Mobians, not the Black Arms, as Gothic Gardens are built of stone and have stone castles, whereas the Black Arms grow everything out of living, organic tissue. Most of Gothic Gardens is gold, red, and green, with some gray stone, as opposed to Black Arms buildings and objects, which are black, red, and sometimes purplish.
My theory, then, is that there was a medieval culture that met the Black Arms and devoted themselves to worship and servitude of the alien race, going so far as to include the Black Arms logo on human/Mobian (Earthling?) decorations.
I'm still not far enough into all the Boom media to know if there's any evidence to contradict this, but this is my working theory until I learn otherwise.
*Footnote: Come to think of it... those thorns that appear all over the place are also red and purple and kinda gross-looking... could it be...???
