The Weirdo or Capone is the most popular character/monster in It Lurks, besides from their original form which was known as Capone but has since then gone by the name of "The Weirdo" in the death tips in chapter 5 which is their only current appearance after you pull the third lever, at their part you are given the task to find a key in the lockers. A very cool feature Crow made was The Weirdo can hear you open lockers if they're within so much distance of the locker, they will growl and run to the locker immediately. When you find the key and open the door The Weirdo will become friendly, not attacking you even if they see you.

AI Mechanics
The Weirdo will randomly wander to a position, I think that it is based off of lockers you open. If you don't open lockers they will still randomly wander but not as "intelligent" you could say, If you open a locker The Weirdo will immediately wander to that room, if you open a locker too close to The Weirdo then they will growl and run to the locker, in that short amount of time you gotta get the heck out of there and not run into The Weirdo on your way out,
