It'll be... interesting to play/write a character that doesn't/can't talk. It's something I've always wanted to try, but never got the chance.
Oddly, even though I usually go through 10 billion character ideas with RPGs before finally settling on one, I'm 100% satisfied with Kaiser, despite him being, like... only the 2nd idea I've had.
Just gotta do a bunch of drugs and write his history.
