Most of the actors in Mortal Kombat used for the images of the characters were actually martial artists. The actress for Sonya Blade, Elizabeth Malecki was the exception as she was a ballet dancer.

Reptile in Mortal Kombat is actually the first secret character in fighting game history.

Mortal Kombat co-creator Ed Boone named Sonya Blade after his sister.

Liu Kang is the only character in Mortal Kombat 1 to feature a fatality that doesn’t technically kill the opponent.
