* ActorAllusion:
** This universe's Johnny Cage is a former ''Franchise/PowerRangers'' star. Matt Mullins, Cage's actor, also starred in ''Series/KamenRiderDragonKnight'' as Kamen Rider Wing Knight. ''Franchise/SuperSentai'', the series adapted as ''Franchise/PowerRangers'', acts as a brother series to the ''Franchise/KamenRider'' {{Toku}} series. Mullins was replaced by Casper Van Dien for the second series, who appeared alongside ''WesternAnimation/MortalKombatDefendersOfTheRealm'' Raiden alumni Creator/ClancyBrown in ''Film/StarshipTroopers''.
** In the pilot episode Capoeira expert Creator/LateefCrowder was Baraka, and Ian Anthony Dale played Scorpion. Both men previously portrayed [[Film/Tekken2010 Eddy Gordo and Kazuya Mishima]], respectively.
** Cary Hiroyuki-Tagawa, the [[Film/MortalKombatTheMovie original Shang Tsung]], returns to the role after over a decade. He was also [[Film/Tekken2010 Kazuya's dad]].
* AllStarCast: For a web series, at least. Creator/JeriRyan as Sonya Blade, Creator/MichaelJaiWhite as Jax, Creator/TahmohPenikett (fresh from success in the new ''Battlestar Galactica'' and ''Series/{{Dollhouse}}'') as Kurtis Stryker, and in the second season Creator/CasperVanDien as Johnny Cage and [[SugarWiki/MomentOfAwesome Cary-Hiroyuki Tagawa reprising his role as Shang Tsung.]]
* AscendedFanon: Hydro appearing as a cyborg in Episode 9 might be a nod to a Lin Kuei companion of Sub-Zero's in the Malibu comicbook adaptations with the power of water (long before [[VideoGame/MortalKombat3 Rain]] became popular and [[VideoGame/MortalKombatArmageddon mastered]] [[VideoGame/MortalKombat9 it]]) who later became a scarily popular fan and ''{{VideoGame/MUGEN}}'' character who functioned as a Cyber Sub-Zero [[HilariousInHindsight before they actually did it in canon]].
* CreatorCameo: In the Johnny Cage episode: Ed Boon as Ed "Goodman". Sure...
* TheOtherDarrin: Of the eight characters that carried over from the first season, only Kitana and Scorpion retained their original actors. Johnny Cage, Raiden, Mileena, Stryker, Sub-Zero and Shang Tsung were all re-cast for the second season.
* QuietlyCancelled: This seems to have been the fate of the series after season 2. Season 3 was reportedly filmed in its entirety but never released; [[https://www.cbr.com/what-happened-to-mortal-kombat-legacy-season-3/ some]] speculate this was because of Machinima's buyout by Warner Bros and later dissolution in 2018, effectively making it [[ScrewedByTheNetwork dead in the water from legal problems]].
* RoleReprise: For the second season, Creator/CaryHiroyukiTagawa returns to the role of Shang Tsung, after nearly two decades and at least one franchise reboot.
