[@clanjos] Dynamite Sanchez is accepted. Best Fatality. 

[@Mr_pink] Williamson is accepted, love the idea of a ronin in MK. 

And as to the boss character question, yes they are unplayable. Raiden is unplayabale as well, because he serves as mainly a guide for the heroes. And Kotal Kahn doesn't exist yet since this is early in the MK timeline. Although for what it's worth I think Kotal Kahn is pretty cool. Honestly, all of the new additions in MKX were great. 

We'll be accepting a few more characters before we get started, and I still have to post my own CS at some point. I'll be playing as Johnny Cage. I'm curious to see if anyone else will step into the shoes of an existing MK fighter. Either way, we have a solid roster I think.
