These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Mortal Kombat Defenders Of The Realm
Big Lipped Alligator Moment: At a point of Sting of the Scorpion, Sub-Zero faces a giant snake that has nothing to do with Scorpion's undead army. Justified because they are in Outworld, where danger is at each corner.
Ensemble Darkhorse: People generally liked the version of Raiden in this show.
Fanon Discontinuity: Not towards the show itself, but this cartoon's existence makes Mortal Kombat: Annihilation easier to ignore, due to the cartoon taking place after the first movie while disregarding the second.
Hilarious in Hindsight: The Sub-Zero/Smoke episode, two-fold. One flashback shows Sektor and Cyrax as humans, with Sektor as a large black man and Cyrax as a white man. Just reverse their races and the cartoon just nearly called it right.
Furthermore, Sub-Zero's "MK 3" costume in Mortal Kombat 9 actually looks more like the Lin Kuei uniform he wears in one flashback of the very same episode as well.
One of MK 9's missions in the Challenge tower is named "It's Kombat Time!" and you play it as Sonya...
Narm Charm: The animation is crappy, the dialog is sometimes stupid and there are lots of really weird things (portal closing device in a police baton?), but there is something charming about this cartoon.
Never Live It Down: Jax having been a fat kid was a thing of one episode, yet it's the thing most people remembers about the series version of the character.
Too Good to Last: Ran only for a single 13-episode season, even though it might have been the plan.
What Do You Mean, It's for Kids?: Bet you would never think they could make a Saturday morning cartoon out of an ultraviolent video game series, huh.
