Recently Youtube recommended this video to me, it's mostly going over the current nega drama but it includes a segment about RobotnikClaus, an imensely offensive series of animations made by a Newgrounds animator named MugiMikey, featuring Michael Kovach voicing classic Robonik, a homosexual rapist pedophile, that hasn't been mentioned yet in this thread.
I did a small surface search for it and found the entire thing on youtube
Apart from the reupload, I found a
TVTropes page that points to
MugiMikey's Newgrounds page as a source for the videos.
At some point they were removed, but if you look at his
archived page they're still there.
