why is mortal kombat spelled with a 'K' and not with a 'C' like Combat

Answer 1

Someone wrote a "K" over top of the "C" in Combat on the creators whiteboard, and it just stuck afterwards.

from: http://en.wikipedia.org/wiki/Mortal_Kombat

Answer 2

Because, sometimes you're so cool, you become kool.

Answer 3

Wikipedia says: "The series itself commonly uses the letter "K" in place of "C" for words containing the hard C sound, thus misspelling them. According to an interview with CraveOnline, Ed Boon stated that during game development they usually spell the words correctly and change them later when the developers recognize an opportunity"

 

Hope it helps :)

Answer 4

Because it is KOOL. It also attracts attention.
