Few mistakes. "Kahn" not "Khan". You forget about Cyrax and Sektor. Also you should accept spelling "Kollector" without "The". Sheeva was in campaign, you must add her.
I'll Fix the Khan spelling, but every confirmed character means everyone playable in the current game. Now Kronika is not playable, but I included her because she is the final boss of the game, and I feel she deserves to be included. By your logic with Cyrax, Sektor and Sheeva being on the list, I would have to include people like Kharon, Fire God Liu Kang, etc. Also I do accept spelling for Kollector just as its self, I just checked.
