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 avian-esque features, including a long pointed beak-like nose and black eyes. He was picked up by a travelling carnival and used as a side-show attraction until he was left behind when the caravan left town- it is never specified whether he was accidentally forgotten or intentionally abandoned. Some time later, Bird Boy was accused of burning down a shop, although it is very heavily suggested that he was most likely framed by the real arsonist. He was driven out of the town as a result and wasn't seen or heard from again for twenty years, though a newspaper article suggests that the residents may have been anticipating his return. As an adult, he became the ringmaster of his own carnival and travelled from place to place until he returned to the town he'd been banished from, where he proceeded to carry out his revenge against the townspeople. However, after trying to hypnotize the player, Raven winds up being hypnotized himself and is rendered powerless. After being subdued by the player, he becomes a side-show attraction in his own carnival, with Edgar having taken his place as the ringmaster. It is never revealed what eventually became of Raven, whether he remained in his hypnotic state permanently or if he happened to somehow snap out of his trance- and in the latter case, whether he heeded the player's advice and bettered himself or plotted vengeance once more.

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 a few interesting similarities with Dr. Hare.
 * Both of them are animal-themed villains and use mind-control as part of their schemes.
 * It is also worth noting that while they are major characters in the Islands' plotlines, they actually play very little role throughout the majority of the games themselves, only being mentioned by various non-player characters before stepping in near the end to confront the player- ironically, this is also the same in Mordred's case.
 * Interestingly, Monster Carnival Island was supposed to be released in 2008 but that year 24 Carrot Island was released instead. This could suggest that the creators set the Monster Carnival project aside at the time so they could work on finishing 24 Carrot and other Islands. This may be backed up by some of the creators' statements, as they mentioned in a few blogs that they had suffered from writer's block while working on Monster Carnival.
 * In the trailer, Ringmaster Raven's eyes were black with white pupils and what appeared to be a dark red iris, which is how he appears in the Island with his mask off though lacking the crimson iris. However, when his mask is on in the Island, he appears with regular white eyes with black pupils. This was probably a last-minute change to surprise the player in the end when he reveals himself. It is also possible that he could have been wearing contacts to either appear inconspicuous, hide his true identity from the player or townspeople, or all of the above. It's also worth noting that when hypnotized, his eyes are unique compared to those of other hypnotized Poptropicans- whereas the others' eyes are white with tiny black pupils that spun in circles, his are a dark olive green with white eyeshine and large black pupils.
 * Though he primarily used sodium thiopental and a hypnotic machine to control minds, it is implied that he can also hypnotize people with his eyes, as he was hypnotized when the player turned the mirror on him, showing him his own reflection.
 * It is likely that Ringmaster Raven is a magician or may even have actual magic powers, what with his use of hypnotism and his apparent ability to disappear and reappear at will.
 * This theory could be supported by his minions- normal humans who were turned into monsters -as their exact method of transformation is never fully explained.
 * They could have actually been turned into aggressive beasts through some supernatural force, literally shape-shifting into different forms at the ringmaster's command.
 * However, they could be having some sort of illusion cast onto them, simply giving them abnormal appearances but not actually changing their physical being, with their somewhat hostile behavior towards the player being an effect of their hypnotic state.
