Seriously? Am I the only one who sees the obvious resemblance here? Look at [url=http://i175.photobucket.com/albums/w156/Sonic343/DoctorAchronos.png]this[/url] highly detailed comparison that I spent whole seconds creating. The appearance of these two is far to similar to be coincidental. So, OP, while you were on the right track, it turns out that Achronos is actually Dr. Octopus. There is no other feasible explanation.
