|What's missing, Scoobypedia?|
Harry the Hypnotist was a circus hypnotist.
Harry is a Caucasian male who seemed to be either middle-aged or older. He is bald on the top of his head with the remainder of it white and grown out.
In his disguise, he seemed callous and even sadistic having no regard for the lives of those he hypnotized. He could've severely injured or even killed Scooby, Daphne Blake and Shaggy Rogers by making them perform extraordinary feats under hypnosis. He was also vindictive as he was willing to go to great lengths to ruin the circus.
Skills and abilities
Harry was a highly intelligent and skilled hypnotist who could put anyone under a trance easily whether it was a person or an animal.
Scooby-Doo, Where Are You!
Years later, he returned for revenge by dressing up as the Ghost Clown, scaring away the performers. When the gang came to investigate, he hypnotized Shaggy, Scooby, and Daphne to do dangerous acts in Mr. Barnstorm's circus, causing mayhem. He was eventually defeated when Shaggy and Scooby used a mirror against him, and was left for the authorities once again. (Bedlam in the Big Top)
