Ah, yeah, I still remember my first Yao Guai. I knew about Deathclaws so they didn't surprise and scare me as much as Yao Guai. Once in Fallout 3 I was taking Sticky to Bigtown and we met a Yao Guai. I thought we were dead but I'd equipped Sticky with pretty good weapons and armor so he and Dogmeat killed it in a few hits, no joke. They killed it before I could get into VATS. I was shocked for a good minute.
