User blog comment:AustinDR/PE Proposal: Dr. Robotnik (SATAM)/@comment-2059440-20191029231451

he is definitely the character I remember most in the Sonic series due to SatAM being one of the first real Sonic things me and my friends saw - while I never got into it as heavily as some friends this Robotnik definitely stuck out as darker than any of the others and if I remember right even the intro song depicted him sweeping over Mobius and basically wiping out everything he touched.. also the roboticization process in SatAM was probably among the most nightmarish depictions of what was originally a silly concept.

I'd say yes for being a rather blatant genocidal dictator, something you don't normally associate with Sonic.
