The initial release of the arcade version features unused character biographies for the game's playable cast. These biographies are facetious in nature, for instance claiming that Shinnok was an ex-model for the Bicycle brand of playing cards and that Scorpion's mission in life is to scold a friend for punching him when he was a child. The joking nature of these biographies likely contributed to their disabling in the original build and outright removal from the game's code in subsequent updates. Examining the biographies through hacking the game shows that two of them are unfinished. Fujin is referred to as "Windgod" and Noob Saibot's biography is mostly recycled from Raiden's, with the only original portion being the cut-off opening line.
