As someone old enough to collect Archie Sonic from debut.... hush....
It's funny because in the end it was really SatAM being forced into becoming SegaSonic and everyone, even at the time, could see how it simply just. Could. Not. Work. In the end.
I mean, that wasn't really the case at first, as paradoxical as it sounds. Archie was just SatAM extended, right? So it wasn't too much a stretch with how especially little Americans knew of SegaSonic lore - and how little of SegaSonic lore existed in the first place, it turned out - to slap, say, Amy Rose into the comic as just another Knothole resident, and introduce SegaSonic chars as residents of Mobius in general, and hell, Metal Sonic made enough sense as in why WOULDN'T Robotnik try to make a robot version of Sonic to one-up him? Just as the show made up stuff off of very little official knowledge and adapted as it saw fit, so did the comic. The kicker is,
the adapted versions were still ultimately in service to SatAM's core concept. All those residents of Mobius, Knuckles and the Floating Island, etc. were still fending off Robotnik's global reign of terror roboticizing the entire planet under his control. Amy, as I said, was another Knothole resident saved from the chaos of Mobotropolis becoming Robotropolis. And so forth.
But then Sega started pushing Archie into adapting more of the game stuff, and this is the Dreamcast/Adventure era starting in 1999, when suddenly Sonic had
real plots and personalities, and none of it fit into the American Sonic characterizations that had been running in salutary neglect since about 1992 or so. And this is just.... not workable. There's suddenly entire cities of "Overlanders" (humans) hidden away from the rest of Mobius that aren't connected to the people Robotnik and Snively came from? Convoluted ways of turning Sonic and Robotnik into their Adventure selves, trying to turn Tails from a lil' kid into a mechanical genius on par with Rotor and thus Rotor suddenly has nothing to do, the echnidas suddenly getting civilizations and backstories NOTHING like the Archie-made ones...
Yeah.
For all of SatAM and Archie's issues (pun aside), it had a core concept, and ultimately, that core worldbuilding was mashed into something completely different. Archie probably would've been better off rebooting the comic somehow in time for the Adventure era and give SatAM a proper ending in that regard. Obviously they couldn't, that'd piss off too many readers, but perhaps ending the comic at issue #50 as intended with Robotnik's death is as good as any to pretend SatAM concluded.
what if knuckles turned green
Ironically I always liked the idea of Super Knuckles being green to contrast to Super Sonic, even if him being colored pink is too deep into the fanon now.
No joke, I always thought Mecha Sonic was a slick-ass design and I'd kill to see a good fanart piece of him fighting Metal Sonic with them both in proper proportions to one another. Spaz knew what he was doing with Mecha Sonic and Mecha Knuckles's designs.
