This Sonic CD Theory Is INSANE

Fun is infinite in Sonic CD when its a game that has some crazy theories for fans to speculate. For instance, its place in time may not be as... accurate as we thought. Let's go over the Sonic CD timeline theory!

What do you think? Are you a 1 > CD > 2 kinda person, or are you a Sonic CD Truther and think it fits elsewhere?

[remukko]

Are we all forgetting Sonic CD is a time travel plot? Metal Sonic is fought in the future. It could be that Eggman was still innovating on robotic Sonics in 2 and 3, and only made Metal chronologically after Sonic 3. A bit confusing, but that's how time travel plots are.

[nationwideris]

6:21 Japanese Sonic 1 manual confirms that Eggman and Sonic have met before this. This is however their first time fighting for possession over the emeralds

[Your_LocalWizard]

I don't think the Metal Sonic argument is the slam dunk a lot of people think it is. Sure, Metal might have the most hype around it, but he was also assisted my Eggman during his fight, not to mention that Metal was designed to race Sonic, whereas the Mechas were made to guard the Death Egg, and presumably Mk. II was made to absorb chaos energy. The mechas aren't designed as upgrades for Metal, they were designed for different purposes

[wessltov]

Why is the logic of "Eggman may just have been experimenting" not applied to Metal Sonic being replaced? Especially if Sonic destroyed him previously

[papyrusty]

My theory is that sonic CD takes place before sonic 2, and the reason sonic's spindash is different is because tails taught sonic how to properly spindash, rather than the crappy one he had in CD.

[Chokun-Gaming]

I've heard a theory that states that CD happens between 1 and 2 _for Sonic_ but due to the time travel shenanigans of little planet it was some time after 3 & Knuckles _for Eggman_ which would explain Sonic's sprite and janky spindash while also letting Metal Sonic be the most advanced robotic copy of The Hedgehog chronologically

[marsnil]

I stand with the theory that Sonic CD is still placed between Sonic 1 and 2, but Metal is just quite literally from the future, Eggman simply doesn't know how to build him yet, but he manages to time travel and bring him back from another timeline.

[pointwoods]

The Spindash thing is just a development oversight methinks. It wasn't originally meant to appear in cd but was added because of sonic 2. Amy's lack of inclusion in other games is also a development thing, since sonic cd was made by the half of sonic team that stayed in Japan after sonic 1. The team who also went on to create knuckles chaotix, explaining her inclusion there.

Sonic CD Theory:
Sonic isn't a CD

[MilkshakeSkunkette]

if i recall, wasn't the "see you next game!" screen featuring tails with that car- actually in reference to sonic drift? which was released after sonic CD?
would also explain well... the car xD

[vaporvd]

Considering CD is a title focusing around time travel, it would make sense that, even as the first robot, Metal Sonic would be the best. Simply put, Robotnik has more time, starting his work in the Past, all the way up to the Future.

[HutchMuch]

people seem to forget that *metal sonic failed* in cd, just like how all the other robot sonics failed in their games. it makes perfect sense to me that eggman would abandon metal after that

[Kelps.mp]

The thing with Eggman using worse versions of Metal Sonic is probably because Metal got trapped in Little Planet when Sonic freed it from Eggman's chains, so Eggman went to use the previous attempts of creating a robotic Sonic, thus why they are just pushovers.
"But Sonic 4 takes place after Knuckles' Chaotix, so how was Metal still in Little Planet even though he was used twice before it?" At this point, I don't even try to piece it together.

[ryanlittleton]

6:21 an interesting note is that Japanese manual says in Sonic 1 this isn't the first time Eggman and Sonic have interacted with each other

Counterpoints to the Counterpoints

1. Tails and Sonic don't have to be together. While it is mildly out of character for them to not go on vacation together we see in the Adventure games among others that at least right now they live their own separate lives and can even go decent intervals of time without seeing each other.

2. We are reading way too far into this teaser image. Sonic 2 and CD were in development at the same time by two different teams. The Tails image was likely just them wanting to reference the character because they couldn't add him

3. Is actually pretty sound. Sega of America tends to add story elements that don't need to be there, and I mean we got an official mention of Tails Sky Patrol before Tails' Adventure

4.Yeah that's also fair, but I mean I explained half of them

[Cheesetendo]

3:40 The whole plot of Sonic CD involves time travel with Eggman having control over the dark future so i always thought thats where Metal Sonic came from, it would explain why hes more advanced than the other sonic clones and why he doesnt show up in other classic sonic games, hes just from the future so he wasnt built yet.

[gregtom]

Nope
sonic and eggman DID NOT MEET in Sonic 1, that game's japanese manual confirm they had multiple encounters before the game's events occured

[kylegetz]

Metal sonic was built to match Sonic’s speed using future technology, eggman built the mecha sonic robots to overpower sonic or to try to recreate metal sonic with more limited technology. The spin dash is weird in sonic cd because tails hasn’t taught sonic a better way to do it yet. “See you next game” is referring to sonic drift. Amy Isn’t in sonic 2 or 3 because she wasn’t needed until sonic adventure.

[toottootsonicwarrior]

My theory is that I think Metal being absent during 2 could be explained as the robot simply being out of commission since it's battle against Sonic.

We know it's one of Eggman's crowning achievements so it may have taken a long time to repair such a complex machine. This complexity may have also been the reason for all the future 'Robo Sonics' being such duds as Metal may have been a "lightning in a bottle" moment for Eggman and he may have struggled to recreate his masterpiece, only coming close with Mecha Sonic.
