Ringmaster Raven

 Ringmaster Raven (also known as Bird Boy) was the main antagonist of Monster Carnival Island.

History
Ringmaster Raven was an orphaned boy who was born with bird-like features, including a beakish nose. He was accepted into the travelling carnival, but was left behind, thus becoming homeless once more. A few months after, Bird Boy was accused of burning a house down, although it is unknown if he truly did this or if this was just a result of the townspeople's prejudice against "monsters". He was driven out of the town as a result, although he swore revenge. He eventually became the ringmaster of the travelling carnival and proceeded to carry out his revenge on the townspeople.

Role In Monster Carnival Island
He entered the town in the carnival and does not do much for the first half of the island. However, he hypnotizes the carnies into heading deep into the woods, and, disguised as a cloaked figure, transforms the carnies into monsters. He then hypnotizes Edgar, a carnie apprentice, and he tricks you into making him some more of his Hypno-Powder (sodium thiopental). He then reveals himself to be Bird Boy, and attempts to transform you into a monster as well. However, you avoid this and after a long chase (and saving Edgar with fried dough), you corner him in the mirror maze and hypnotize him into becoming a chicken. He then returns to his carnie family, only now as the Incredible Chicken Man.
