>Speaking of Sonic 4, the Sonic 4: Episode 1 manual
There was a manual?
I also wouldn't consider anything said outside of the games, outside of any continuity at all, to be canon. Creators have a lot of ideas that change before they make it to publication, or never end up getting put to paper at all. Until an idea is actually published in a canon work, it's not canon. Otherwise you'll drive yourself crazy trying to reconcile contradictory quotes from a creator who, in reality, was just talking about ideas he had but will continue to refine until they are published.
That said, let me talk about my own headcanon.
The bit of headcanon I'm most autistically attached to is the idea that Sonic 4 leads into Sonic the Fighters. Sonic 4 ends with the Death Egg II being left non-functional but not destroyed. Sonic the Fighters is then about the Death Egg II. Presumably Robotnik made some upgrades to it so it didn't need Little Planet to function anymore, plus it had all those moons or whatever attached to it.
And btw, Sonic 4 is a "sequel" to CD in that it carries on story elements, but it literally cannot take place immediately after, because Little Planet only appears once per year. Sonic 4 needs to take place almost a year after CD, leaving plenty of room for other games to take place.
As for Eggman Nega, it's easy enough to just say that he is from the future, but in Rush he not only went back in time, but also to another dimension.
Caring about the Blue Chaos Emerald in '06 is too autistic even for me. It's not a big fucking deal.
BTW, the 8th Emerald in Fighters is the Master Emerald. That's the one you grab from Knuckles. I don't care if it doesn't look like the Master Emerald in game. The looks of the emeralds have been inconsistent since Sonic 2.
There's no reason to say Drift isn't canon. It doesn't Post too long. Click here to view the full text.
