Meat your worst nightmare.
- The menu music
. It's not outwardly intense or menacing in any way. It's a quiet, subdued, and save for some drums completely ambient piece that's just apprehensive enough to be incredibly unnerving. Sure is a joyous thing that you get to hear it every time you start up the game. - Not to mention, the Scare Chord music that plays throughout the Kreate-A-Fatality system. It only gets more and more intense as you put in more inputs, ripping apart the opponent as they let out screams of anguish. All of this never stops until the very end, where the music climaxes and the opponent is Deader than Dead. Although it can be more than satisfying as well, especially if it is an Ultimate Fatality.
- The death traps in the Kahn Arena are significantly scarier than the rest of the arenas, which can be considered mundane or even humorous. There is one on each corner of the stage - a pit with many long spear-like spikes that will impale anyone unlucky enough to get hit into one, an Acid Pool that will leave nothing but a skeleton, a lava pool that burns until nothing is left, and massive grinding gears that can shred the opponent alive.
- Special note goes to the Bell Tower stage fatality. If you finish your opponent off with an uppercut on the lower floor, they will go through the floor and onto a conveniently-placed spike. As if that wasn't enough, they will slowly lower onto a blade that cuts their limbs off, with a rat carrying off one of their legs to add insult to injury. Not to mention that your opponent is still alive by the time the screen fades to black.
- The titular Armageddon. Because of how powerful the kombatants are becoming, it's grown to a point where all realms - all of them - are going to be destroyed violently. In other words? It will be The End of the World as We Know It. Not to mention, it is nigh-impossible to even stop, meaning that it will be an inevitable doom - the MK universe had collapsed upon itself due to its own nature. If not for Raiden's Continuity Reboot, everything would have been lost forever.
- Blaze's boss form is a dramatic contrast from his humanoid form in Mortal Kombat II, Deadly Alliance and Unchained, in that he is now a gigantic, hulking fiery brute with rock-like armor, and is also one of, if not the absolute tallest character in the game. His character portrait shows him expressing what can only be described as Unstoppable Rage.
- The ultimate aftermath. Taven's "konquest" had failed, with Blaze killing him atop the Pyramid of Argus. However, even if Taven did win, his quest would have proven itself to be a gigantic waste of time anyway, as proven by both the Konquest ending and his Arcade ending. Blaze's energy would not kill the kombatants in the Edenian crater below, nor nullify their powers as intended - but simply just augment their strength (or even do nothing to them at all), resulting in the quest failing by any account. And in the end, as Mortal Kombat 9 depicts, through all the deaths of warriors good and evil, all the blood that was spilled, all the kombat that spread through the Edenian crater, Shao Kahn is the one who finally defeats Blaze, claiming the ultimate victory after many years of failure; giving a tremendous Breaking Speech to Raiden who dies by his hand. While Raiden does reset the timeline successfully, his original counterpart is done for, and he had also forever doomed the original game timeline once and for all. Armageddon had come and gone, and after the dust settled, evil had triumphed at last.
- But even then, it's not a happy ending for Shao Kahn. After spending a few years afterwards to take over all the realms out there and becoming a being above all else, he goes insane from grief and boredom due to the fact that he can no longer take over any other lands and that he can never enjoy a challenge ever again. His ultimate goal becomes his worst nightmare and he is stuck that way, unable to die and unable to ever enjoy whatever made him happy.
- if (Dark) Raiden had won, it would not have been much better for the realms either, judging from his Arcade ending in this game. He would destroy all the other non-Earthrealm realms in his Knight Templar-induced fury after absorbing the power of Blaze, dooming a good chunk of the cast (some of whom were/are his allies) and scores of people who had nothing to do with threatening/invading Earthrealm. This proves that at this point, Raiden had been corrupted into something not much better than the evil he had once fought.
- Several arcade endings qualify, especially the ones where a villain wins:
- Smoke's ending has Blaze's power convert his body and the nanomachines that surround him into unstoppable and rapidly replicating Grey Goo which eventually consumes everything in Edenia.
- Jarek's ending has him taking Ax-Crazy to an all new level and using the other kombatants' fatalities against them, ripping Sub-Zero's own spine, tearing Kano's heart out, bisecting Kung Lao and ripping Jax's arms off.
- Kai's ending is scary simply because of how ominous it is. He gains a Psychic Link with the One Being, the entity from which all the realms spawned from. Kai is able to see the past and present of the realms but when he looks to the future he sees nothing.
- In Mileena's ending, she and Kitana temporarily fuse together and when they separate the two have switched features — Mileena now has Kitana's beauty while Kitana has Mileena's Tarkatan teeth. Mileena once again poses as Kitana and claims her throne while Kitana is imprisoned in the palace dungeon where she is driven mad.
- Kira's ending has her save Kobra, only for the latter to drain the life force out of her and leave her for dead.
- Conversely, Kobra's own ending has him challenge the Elder Gods, but since he has to choose a queen to rule along with, he picks Kira, who, after being transformed into a goddess of death, siphons the life out of him with a Kiss of Death.
- While Taven's konquest ending at least has Taven swear to find another way to prevent the Armageddon, his arcade ending lacks even that and is even worse. Blaze's death only augments the warriors' strength, making things worse than they had ever been. Argus himself sounds crushed during the narration, lamenting that the quest was a complete failure due to the circumstances he couldn't see coming.
- In Rain's ending, he becomes a god after absorbing Blaze's power, and uses the given role of Protector of Edenia to take over the realm, with Argus's Elder God status keeping him from intervening.
- Baraka kills both Shao Kahn and Onaga with elongated blades when they try to attack him, and then offers Mileena a choice to be his queen, which she accepts.
- Mavado absorbs Blaze's power and discovers he can mind control anyone with the Red Dragon symbol, which leads to him commanding his army to overwhelm Special Forces and the Black Dragon clan, converting their members into his loyal slaves.
- Moloch is driven mad with newfound strength and proceeds to demolish not just the Pyramid of Argus, but the entirety of Edenia as well, making it similar to the Netherrealm - a bare wasteland. It backfires on him, too, as with all portals destroyed, he cannot get out and has to remain there as a victim of his own destructive rage.
- Drahmin does not receive any powers upon defeating Blaze, his mask does instead. Said mask takes him fully over and turns him into a bigger monstrosity fueled by rage, who defeats his former ally Moloch - and the narration reveals that this is only the beginning.
- Frost summons her ancestors, the Cryomancers, and has them possess the Lin Kuei, afterwards conquering the realms and leaving each of them a frozen wasteland.
- Sheeva is brought to the Elder Gods who, out of disappointment that neither Taven nor Daegon have completed their quest, turn her into a goddess of destruction, which leads to her destroying the realms with a powerful Kamidogu before reforming them anew, with nothing the way it has been.
- In Khameleon's ending, she turns Shao Kahn into a Saurian, a process so painful and horrific that he begs for mercy. She then does the same thing to his allies but soon loses control of her power, transforming the heroes into Saurians as well.
- In Onaga's ending he delivers a No-Holds-Barred Beatdown to Shao Kahn and then has him tortured by Shang Tsung and Quan Chi for all eternity. Of course, given this is Shao Kahn we are talking about, one can be forgiven for thinking it is a well deserved fate.
- Nitara defeating Blaze transforms her into a blood god who uses her power to enslave all the other kombatants.
- Shujinko succeeds in slaying Blaze, only to be driven mad by the powers he receives and strike out against the Elder Gods.
- Shang Tsung gains the ability to alter other people's forms to his liking. He makes use of this by transforming Shao Kahn into his centaur slave. The implications of Shang Tsung doing something like this or worse to other people are nothing short of terrifying.
- With Blaze's power, Havik meshes and jumbles up all the realms in a grotesque way until nothing is the same anymore.
- Kenshi regains his sight and has all of his other senses exponentially increased. Unfortunately, the sensory bombardment becomes too much for him and he is forced to seclude himself in a dark, soundless chamber.
- Dark Raiden takes his Knight Templar tendencies to all new levels by wiping out all the other realms, believing all of them to be a threat to Earth.
- Meat's existence as an unfinished experiment by Shang Tsung is scary enough. His Armageddon ending has him gain the power to shapeshift. But since he can look like anyone, he suffers a Shapeshifter Identity Crisis and disappears into obscurity.
- Blaze's ending is arguably the most disturbing just in terms of sheer scale: put simply, no one, not even one kombatant, could defeat him. This of course leads straight to Armageddon happening uninterrupted, bringing about the end of all reality with no one to push the Reset Button...
