He actually existed! The French Maurice Tillet
You’d imagine how these types of diseases inspired people to believe in Ogers, dwarfs and all sort of creatures that are based on a human deformity.
Maurice Tillet (October 23, 1903 – September 4, 1954) was a Russian-born French professional wrestler known as The French Angel. Tillet was a leading box office draw in the early 1940s and was twice recognized world heavyweight champion by the American Wrestling Association run by Paul Bowser in Boston.
He had Acromegaly (excess growth hormone), a disease that made his bones grow uncontrollably large and his skin thicken, so for many people he looked weird, and many would say scary and ugly like Shrek. But as Shrek he was a charismatic guy.
