- Fan Nickname:
- 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".
- Fan Remake: Well, there are two unofficial ports made for this game by an unknown company, for Sega Genesis and SNES, named respectively MK5: Mortal Combat ~Sub Zero~ and Mortal Kombat Mythologies Gold 2000. If you think the original game is bad, just AVOID those. Or not.
- Stillborn Franchise: This was intended to be the start of a "Mythologies" beat-em-up series, with a follow-up centered around Liu Kang planned. That was of course scrapped following the game's negative reception, but that wouldn't stop Liu Kang from getting a beat-em-up spin-off of his own later down the track.
- What Could Have Been:
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!"
- 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.
- One kind of Mook that was to be in this game was known as a "Netherrealm Hound", which is the Mortal Kombat universe's version of a Hellhound.
