User blog comment:AustinDR/PE Proposal: Dr. Robotnik (SATAM)/@comment-1705775-20191030224408

easily the most evil Robotnik and worthy of Pure Evil, even the Archie comic version of Robotnik had tiny moments of either being silly and/or tragic.. the SatAM version? not a chance.. he was the single worst enemy the world faced, the only thing that could of saved him may of been that he never kills Snively but even this small "mercy" is nullified by how he basically treats Snively as a slave and makes his life miserable.. so even if he spares Snively's life he's by no means doing it to be nice, more that he views Snively as his property.. plus in the finale he leaves Snively to die anyway.

oh and unlike most versions of Sonic the roboticization process in SatAM is permanent - which means it has probably the highest stakes in any Sonic media as there's no reset button, at least originally, if your friend got roboticized they were literally dead forever, nothing more than hollow machines.

Robotnik may of been usurped by Naugus if the series was allowed to continue but even then I'd of said he already did so much that he would likely of kept PE status no matter what - wiping out most of Mobius before the show even properly began solidifies this.

he is (as some reviewers stated before) symbolic of totalitarianism and eco-terrorism, the destruction of the environment and an enemy of life itself - all of which are worthy for the status as Pure Evil.
