The Sonic the Hedgehog Headcanon Thread of Lore and Time Stones

You mean my idea on how they were split?

3000 years ago
-Chaos uses the Chaos Emeralds to become Perfect Chaos.
-After Chaos is sealed, the remaining people split the Chaos Emeralds and spread them around various islands, including Cocoa, South, Westside and Angel Island. Debating on the last island*.

50 years ago
-Gerald, while researching the ancient ruins, happens upon one of the South Island Chaos Fragments and uses it for his research aboard the ARK.

Some time before...
-The Battle Kukku Armada finds one of the Cocoa Island Chaos Fragments. The capital ship is sent to Cocoa Island to prep for invasion.

Tails' Adventure
The Battle Kukku Armada attack Cocoa Island for the remaining six Chaos Fragments. They find one more, but Tails recovers the other five and then it before they can make off with it.

Sonic the Hedgehog (Mega Drive)
Dr. Ivo "Extraordinarily Gifted Gentleman" Robotnik arrives on South Island and attempts to locate the Chaos Fragments, since his research and knowledge of Gerald finding one on South Island has him realise there should be six more Chaos Emeralds.

Sonic the Hedgehog 2 (Mega Drive)
-Robotnik attacks Westside Island after following Sonic there. Tails thinks Robotnik wants the Chaos Emeralds from Cocoa Island, Sonic wonders why he is after the Emeralds left on South Island while on Westside Island, and Robotnik is wondering why he's got a signal on Westside Island when the two talking to him think they're not even on the island. All three realise there's more going on than they realise.

Sonic the Hedgehog 2 (8-Bit)
After hiding the Westside Island Chaos Fragments, Sonic returns to South Island where he finds a note from Tails, where he states Robotnik has captured everyone and is demanding the six Chaos Fragments somewhere on South Island. After, instead of uniting the South Island Fragments with their others, they leave them to repair the damage Robotnik has done after hollowing out Gimmick Mountain** and prevent South Island breaking apart.

Sonic the Hedgehog Chaos
Robotnik takes one of the South Island Chaos Fragments, uncaring that they're repairing the damage he caused, and Sonic and Tails scramble to recover the six before South Island breaks apart completely and sinks. They don't know if the other Fragments will function the same way and really don't want to risk blowing the island up completely, so don't simply replace them with the other Fragments.

Sonic the Hedgehog Triple Trouble
Robotnik, after the Death Egg crashed on Angel Island and he has encountered Knuckles, uses his new hiding spot and manages to steal the South Island Chaos Fragments. He uses them to test fire a Death Egg Superweapon, the Atomic Destroyer, to replace one that was damaged but loses the six used in an accident, prompting a race to reclaim them.

Fang, meanwhile, has managed to slip by everyone as Sonic and Robotnik fought and collect the recently lost South Island Fragments, as well as the Westside Island, Cocoa Island (including the Battle Kukku Fragment) and Missing* Fragments prior, plus the United Federation South Island Fragment. He uses ancient temples to remerge the Chaos Emeralds together, eventually merging four of the five pieces back together with the intent of claiming the seven great treasures: the complete Chaos Emeralds.

Sonic, however, claims five of them from him, while Robotnik manages to steal one, leaving one remaining in the temples he was using to refuse them.

Come the Atomic Destroyer, Fang sneaks in, where he tricks and captures Knuckles to try and learn the location of the remaining (Angel Island's) Fragments, as well as try take back the Chaos Emeralds Robotnik and Sonic took. However, when Robotnik arrives to combat Sonic (and him) with a giant mech, Fang sees that he's out of his depth with direct confrontation and bails.

With that loss, he attempts to flee and remain hidden, but Sonic and Tails manage to track him down to an island and take the seventh Chaos Emerald from him.

Sonic the Hedgehog 3
Tails, deciding not to take risks at being caught off guard with more Fragments that Robotnik could possibly find and use against them, begins a blanket scan for Chaos Emerald Energy signatures with a Jewel Radar he invents, just in case. Imagine his surprise when he suddenly detects a powerful signature.

Sonic arrives with a ring he found washed up on the shore, and they recall the legend of the island that was once part of the continent before an incident saw the civilization get wiped out. Figuring a connection, they set out, only to be intercepted by Knuckles, who steals Sonic's collected Emeralds and leaves. Once away, Knuckles places the Refused Emeralds in Hidden Palace, but realises they're still incomplete.

Sonic, meanwhile, begins his adventure and collects the seven missing fragments. After being separated from Tails***, he sees Knuckles sneaking around and investigates, ending up in the Hidden Palace where the seven remaining Fragments respond to the Refused Chaos Emeralds and the Master Emerald, becoming complete once more.


*I'm considering Flickies' Island, since that has it's own "where the Chaos Emeralds lie" legend and has ties to Subspace, where Fang lives. Noted as "Missing" for now.

** Gimmick Mt.'s level description states:
[quote Sonic the Hedgehog 2 (8-Bit) JP Manual]Gimmick mountain is a suspicious mountain. The hollowed mountain is teeming with modern machines. Use gears and conveyer belts wisely. But be careful not to speed too much.[/quote]
I'm using that and the Chaos Emerald's ability to repair damage to justify Sonic Chaos saying South Island suddenly needs the Chaos Emeralds to remain afloat.

***Sonic & Knuckles' manual makes a passing mention of Tails, so I like to assume Sonic and Tails were separated after the Death Egg refell, and Tails doubled back to the Tornado.

Edit:

It's a bit tricky, but we only know he had one. Japanese doesn't really have plurals, while the Gizoid only managed to grab one, and Gerald is thankful it didn't get all seven. So we know he has one at least, and know he knows of all seven, but not if he HAD all seven, or even if he had more than one.

Any further questions, @Rafa Stary?

 

Pretty much.

It's just something I added (Headcanon thread :P). It's just to better justify their invasion and keep the sets to the standard seven. Tails finds six, including the one on the Battle Kukku Armada, so them finding one, securing it back at home and then invading for the remaining six seems a sensible plan and quietly explains out the missing seventh Emerald, without having to change a single line of text.

Professor Gerald's Chaos Emerald. Gerald had a Chaos Emerald and do you really think G.U.N. would just leave it on the ARK after the ARK Incident 50 years ago? They've also been producing Chaos Drives in the past 50 years somehow.

That's a valid point, but then he could have just kept the Chaos Emeralds hidden aboard the ARK when Black Doom was about.

 

Sonic Drift 2 is implied to also take place on South Island, Iron Ruin's outline looks suspiciously like a ruinous Scrap Brain Zone.

Several capsules were ejected, so it's possible the Chaos Emerald(s) may have been among them.

He did, but G.U.N. use them in their robots now, so would have to mass produce them.

When is that said so I may check?

 

Well, unless Space is on Westside Island, we do know they leave the island to go face the Death Egg.

Eh, I assume G.U.N. would not let a jewel of infinite power leave their hands as easily as that.

They are confirmed to be powered by them, and we're just not picking them up in all instances due to lack of use (read: no Chao Garden, the monsters).

 

That's Silver Castle.

There's no reports of them at all prior to Sonic Adventure 2, despite being active 50 years prior.

They woulda been real helpful with the Egg Carrier...

 

No, it reuses the pre-rendered graphics of the Death Egg from Sonic & Knuckles' opening as Silver Castle, but they are two separate things.

 

There's nothing about the Death Egg at all. Robotnik would probably be scrambling (heh) to stop it crashing if such were the case.

Instead, he shoots Sonic and then wanders off to begin construction on South Island, so...

It's, at most, another attempt at the Death Egg's intention with a smaller construct.

 

Honestly, I was expecting this point to be brought up sooner.

Gerald has two sources that lets him know the Chaos Emerald he has is not the correct shape: their images in the Echidna Ruins and the Black Arms, who know enough about the Chaos Emeralds to know Chaos Control and were visiting long before the Perfect Chaos Incident, so can give him a run down on their specifications for a proper fitting for the ARK and, later, the Eclipse Cannon, so he doesn't accidentally give them fragments that wouldn't enable their plans.

The Chaos Fragment they have still outputs Chaos Emerald Energy, just not to the same extent as a full Chaos Emerald. It gives them, at most, 1/5th the output. Enough to get a decent stockpile over the years, but nowhere near the amount a full one could provide.

And we do know G.U.N. does sometimes go around and collect them, like how Rouge has to infiltrate the Security Hall on Prison Island to collect three stashed away.

 

Fang nabbed it.

 

The Master Emerald was a concept since even before Knuckles was finalized. It was the "pillar" deep underground mentioned in Sonic the Hedgehog 3's manual.

So it's unlikely to have been a set that was rewritten for Sonic & Knuckles.
