So, basically Project Jhin is a facehugger which makes you pimp as f if you are infected.

,,,That is one of the most frightning diseases I have ever seen in this game franchise before the mysterious "Space aids".

Jokes aside, Jhin originally was a master of disguise. He was able to change his facial muscles and contort himself to look like any person if nessessary. (The normal skin is actually a imitation of a old man with a walking stick.) It was this talent that made him so difficult to capture.

I find it very interesting in this version that Jhin now forcefully replaces ones head rather than using visual tricks. I also wonder if he still has that "art" obsession on him. And what sort of stuff he makes out.
