Trivia / Mortal Kombat Mythologies: Sub-Zero
Some fans call the God of Earth as "Ohona", though it's unknown where the name came from, or "Chijin", the name of the Japanese god of earth.
For the same reasons as above, "Kumari" or "Suijin" for the Water God. Due to one fan-made sprite comic, he's also occasionally called O'Shin.
"Hinoka" or "Kajin" for the Fire God.
For a long time due to it not having an official name in this game or any other until Mortal Kombat X, Shinnok's Corrupted form had been called "Beast Shinnok" or "Demon Shinnok".
Stillborn Franchise: This was intended to be the start of a "Mythologies" beat-em-up series, but it instead froze those plans until 2005.
What Could Have Been:
Sareena was supposed to become a Canon Immigrant, but was cut from the roster all the way until Armageddon. Specifically, she was supposed to appear in 4 (Fujin took her place), Deadly Alliance, and Deception. She did make it into the Tournament Edition for GBA, but her moveset borrowed from other characters who had been cut from that game.
Sareena's beta name was Eia.
Deception features one unlockable movie depicting a scene cut from the original game where Sub-Zero returns to the Lin Kuei temple, having failed his mission. The Grandmaster promptly executes him as a result. The animation for Sub-Zero writhing in pain was instead used for him teleporting to different areas of the Temple of Elements.
Sub-Zero: "Grandmaster, in failing my mission, I have dishonored the Lin Kuei."
Grandmaster: "An unfortunate event. Your incompetence will cost our clan dearly. Now, you will pay with your life!"
