Xenomorph (Johnny)

Nasty Xeno, hypnotizes u

Xeno with higher sentience than typical xenomorphs. Lovingly (?) nicknamed Johnny after survivors had an interesting run in with him.
Very curious, but timid.

Uses head pattern in a hypnotic sequence to cause tonic immobility to catch prey items. Physically not very strong but very quick and agile. Body can darken for extra camouflage. 

Survivors of Johnny report hallucinations of being in large horrific liminal rooms before waking back up.
