Idea for an SCP Killer

You know what I think would be cool?

An SCP-096 adaption for a Killer! If you haven’t seen any videos of SCP (highly recommended), 096 is the Shy Guy, a creepy figure usually docile and crying, but once someone see’s even a pixel of his face, he enters an uncontrollable rage and bee lines directly to whoever saw them who will, no matter what, always die. Only then will he return to a docile state. That’s not doing it justice but the tldr.

A mechanic preventing survivors from looking at the killer for too long, else granting them some high damage/high mobility perk, would be pretty cool to counter and play against.

How would you add this kinda thing if you had the choice?
