Mortal Kombat (commonly abbreviated "MK") is an American video game franchise series created by Ed Boon and John Tobias. The first four renditions and their updates were developed by Midway Games and initially released on arcade machines, and later to home consoles. The arcade titles were later picked up by Acclaim Entertainment for the home console conversions. Beginning with Mortal Kombat: Deadly Alliance, Midway Games exclusively created home versions of Mortal Kombat up until Mortal Kombat vs. DC Universe. Following Midway's bankruptcy, the franchise was picked up by Warner Bros. in July 2009 and became a part of the Warner Bros. Interactive Entertainment. The development of the first game was originally based on an idea of making a video game (according to Ed Boon, the game was originally meant to be a fast experiment) starring Jean-Claude Van Damme, but that idea fell through and Mortal Kombat was created instead and released in 1992. The original game has spawned many sequels and has been spun off into several action-adventure games, films (animated and live-action with its own sequel), and television series (animated and live-action). Other spin-offs include various comic book series, a card game and a live-action tour. Along with Capcom's Street Fighter, Mortal Kombat has become one of the most successful and influential fighting franchises in the history of video games. The series is known for its high levels of bloody violence, including, most notably, its Fatalities—finishing moves, requiring a sequence of buttons to perform, which, in part, led to the creation of the ESRB. The series name itself is also known for using the letter "K" in place of "C" for the hard C sound, thus intentionally misspelling the word "combat", as well as other words with the hard C sound within later games in the series. Early games in the series were especially noted for its realistic digitized sprites (which differentiated it from its contemporaries' hand-drawn sprites), as well as an extensive use of palette swapping to create new characters.

Mortal Kombat II (commonly abbreviated as MKII) is a competitive fighting game originally produced by Midway Games for the arcades in 1993. It was later ported to multiple home systems, including the PC, Amiga, Game Boy, Sega Game Gear, Sega Genesis, Sega Saturn, Super Nintendo Entertainment System, and various PlayStation consoles.Mortal Kombat II was the second game in the Mortal Kombat series, improving the gameplay and expanding the mythos of the original Mortal Kombat, notably introducing more varied Fatality finishing moves and several iconic characters, such as Kitana, Kung Lao, Mileena and the series' recurring villain Shao Kahn. The game's plot continues from the first game, featuring the next Mortal Kombat tournament set in the otherdimensional realm of Outworld, with the Outworld and Earthrealm representatives fighting each other on their way to the evil emperor Shao Kahn.The game was an unprecedented commercial success and was acclaimed by most critics, receiving many annual awards and having been featured in various top lists in the years and decades to come, but also perpetuating a major video game controversy due to the continuously over-the-top violent content of the series. Its legacy includes spawning a spin-off game Mortal Kombat: Shaolin Monks and having the greatest influence on the 2011 reboot game Mortal Kombat, as well as inspiring numerous video game clones.
