Okay. After reading Sonic X 23 I just had the most unlikely but funny idea for what the story might be.
What if the koo-koo scientist who thought Sonic was a robot and lost his job because of it, mutated the other SONICX members into discolored Sonic lookalikes? It would explain why they aren't typical Metal Sonic designs.
YOU'RE INSANE!!!!!
Actually I think Eggman's repeating his Chao clone experiment, and using Sonic instead.
I hav'nt recieved issue #23 yet, but I was under the impression that the five Sonic clones were supposed to be living clones, as opposed to being robotic.
Actually those Chao were living clones too. Taken from a small portion of Cheese's wing.
I know, I was commenting on the thought of the Sonic clones being robotic, as opposed to organic, as the op suggested.
Ah, I see.
