Buck has two sides in him. Like a werewolf, one side hides on the inside. This is him in a demon form. The neon purple stripes are attached to a inkblot like, spider patch along his spine. The also peel off of him and become solid like spindly spider legs. If you smell the stench of his breath, the scent of death, coming from your closet...well it is already to late to hide so you'd better give him a good show!

He did a terrific job of deciphering the bits of information and character description that I gave him.
