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 deformed, 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 captures the townspeople and his plan was to use the powder to hypnotize the townspeople. Upon your return, 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.

Trivia

 * Ringmaster Raven shares similarities to Dr. Hare.
 * Both are animal-themed villains.
 * Both use mind-control as part of their schemes.
 * Interestingly, Monster Carnival Island was supposed to be released in 2008 but was replaced by 24 Carrot Island. This may mean that Dr. Hare replaced Ringmaster Raven.
 * In the trailer, Ringmaster Raven's eyes were black with white pupils, which is how he appears in the Island with his mask off. However, in the Island, he appears with regular white eyes with black pupils when his mask is on. This was probably a last-minute change to surprise the player in the end when he reveals himself.
 * He is implied to be able to hypnotize people with his eyes as you hypnotized him by showing him his own reflection.
