According to 1UP.com, the early Mortal Kombat characters played virtually identical to one another with the only major differences being special moves. In an interview with Computer and Video Games, Ed Boon stated, "[...] since the beginning, one of the things that's separated us from other fighting games is the crazy moves we've put in it, like fireballs and all the magic moves, so to speak." When asked if Street Fighter and Mortal Kombat would do a crossover, Street Fighter producer, Yoshinori Ono, called Mortal Kombat a very different game from Street Fighter. The Capcom Senior Director of communications compared Street Fighter and Mortal Kombat in an interview with Gamasutra by asking if the interviewer preferred the "precision and depth" of Street Fighter or the "gore and comedy" of Mortal Kombat; he also stated that the Street Fighter and Mortal Kombat rivalry was considered similar to the Coke and Pepsi rivalry in the 1990s. In an interview with Video Games Daily, Senior Producer of Mortal Kombat vs. DC Universe, Hans Lo, called Street Fighter a little more technical fighter in comparison to Mortal Kombat. Midway would keep their single styled fighting moves with four attack buttons which were a different array of punches and kicks and block until they changed this in Mortal Kombat: Deadly Alliance by differentiating characters normal moves and even giving them multiple fighting styles. Beginning in Mortal Kombat: Deadly Alliance and until Mortal Kombat: Deception, the characters would have three fighting styles per character: two unarmed styles, and one weapon style. Few exceptions to this arose in Mortal Kombat: Armageddon, such as monster-like boss characters like Onaga and Moloch who would have only one fighting style. Most of the fighting styles featured are based on real martial arts, though a few of them are not. Goro's fighting styles, for example, are designed to take advantage of the fact that he has four arms. For Mortal Kombat: Armageddon, fighting styles were reduced to a maximum of two per character (generally one hand-to-hand combat style and one weapon style) due to the sheer number of playable characters. Mortal Kombat vs. DC Universe dropped the multiple fighting style trend altogether in favor of giving each character a much wider variety of special moves, however some characters still had multiple fighting styles Baraka, utilizing the retractable blades in his arms (called the "Blade Stance"), and Deathstroke who also possessed the ability to use another fighting style in the form of a sword (called the "Sword Stance").
