After Mortal Kombat 2, Daniel Pesina (who played Johnny Cage and the male ninjas) used his Johnny Cage likeness to endorse some non-MK products including sports supplements, workout videos, and even Bloodstorm, another particularly violent fighting game. The subsequent controversy and falling out was supposedly a factor in both Johnny Cage (and the ninjas) absence in Mortal Kombat 3.

In lieu of Daniel Pesina (Johnny Cage's actor) fallout, the Mortal Kombat cabinet Liu Kang drops in game is missing one character who appears on it in real life.

In the Mortal Kombat movie Johnny Cage performs his infamous "splits punch" on none other than Goro. This is only interesting because Goro is one of the few characters Johnny has never been allowed to "splits punch" in game.

One of the many player rumors about MK2 that was actually true was the random chance for Johnny to perform his Shadow Kick with red shadows, instead of green. Though the exact science behind it was never deduced in that game, both the red shadow kick and red shadow uppercut would become regular special moves in Mortal Kombat Trilogy.

Almost every fatality in Mortal Kombat 1 had some sort of associated glitch, but none was so infamous as Johnny Cage's multiple decapitation punch fatality. By simply mashing out the fatality motion over and over again, Johnny would crouch down and repunch off his opponent's head up to three times in a row (though some claim to be able to get four). Such was the popularity of the triple decap that Midway made it a normal extension of his decap punch fatality when it returned in MK2, and MK Trilogy.
Johnny Cage's name was originally going to be Michael Grimm. His "real" name, John Carlton is actually the name of one of the many MK staff members at Midway. It is unknown if the relatives in Johnny's profile are the real John Carlton's relatives, though.
The full listing of Johnny Cage's performances is: Dragon Fist, Dragon Fist II, Son of Dragon Fist, Sudden Violence, Aquatic Assault, 7 Poisons, Cage Match, The Gist of My Fist, 24 Karate Gold, Ninja Mime, HWAAAAA!!, Exiting the Dragon of Death, Wu Shu (television show), Who's That?, Mortal Kombat, Mortal Kombat II, and Mortal Kombat: The Death of Johnny Cage (unfinished). Though which films and for what reasons are unknown, Cyrax thinks Johnny Cage to be a pretty crummy actor.
According to some Deadly Alliance story materials, Johnny Cage used his Forceball technique to defeat Mutoid Man on Celebrity Smash TV (Smash TV being another Midway arcade game, and Mutoid Man being its first boss).
