this dude. this dude is a bastard. based on the song "mr capgras encounters a secondhand vanity: tulpamancer's propagnosia/pareidolia (as direct result of trauma to fusiform gyrus)" 

hes a shapeshifter that shapeshifts by tearing his skin off and growing new skin onto his body. if he wants to really change how he looks he tears his flesh off as well and works from the bones up but that takes way longer
