Rakkman

Rakk-man is a psycho who has lived in a cave with other Rakk after his family was killed.

Rakk-man can be found past the door that opens in The cold shoulder at the end after fighting off rats. When you enter a area called the rakk cave a chest will be nearby. Once you get close enough he will jump down from the ceiling. During the fight he will have specially named rakk minions help him kill you.

Rakk-man is a obvious reference to bat-man
