Simon Bªr Sinister™

Simon Bar Sinister was the main villain in the Underdog cartoon show.Voiced by Allen Swift and based on the voice and looks of Lionel Barrymore, Simon appeared to be only two feet tall. The "Bar Sinister" in his name was a mark from heraldry, signifying bastardy; on a shield it was denoted by a line (to those facing the shield) from the top right to the bottom left. Generations of children probably never knew that his name could be translated as "Simon, the Bastard".Simon's most famous saying was, "Simon says!" (Wikipedia)
