Overwatch/Nightmare Fuel




 * A.I. Is a Crapshoot: This is what started the Omnic Crisis. Omnics turning against all of humanity.
 * Cryonics Failure: As shown in the image above, after Mei wiped away the condensation from one of the pods, she gasped when she saw her frozen scientific colleagues decomposing. Us, the viewers, didn't see how bad it is, but we can make an educated guess.
 * Earlier before the "Rise and Shine" short, we know this was the fate of rest of the Watchpoint: Antarctica.
 * Fantastic Racism: During and after the Omnic Crisis, some humans who once were friends, neighbors, and co-workers with Omnics justifiably turned prejudice against them, even to the point of mugging and/or kill them.
 * Gone Horribly Wrong: Dr. Kuiper triggering the tiniest black hole ever, which caused him some serious psychological damages and insane gravity powers.
 * World War 3: The Omnic Crisis - An international war that's caused by robots going haywire.
 * Anything about Moira O'Deorain, ranging from her unethical scientific experiments, high possibility that she caused the Omnic Crisis, and suppressing Amelie Lacroix's emotions to make her into Widowmaker.
 * Whether it's in gameplay or story mode, being at the end of her life draining Biotic Grasp.
 * In gameplay, an out of character Mei uses Blizzard or Endothermic Blaster on an enemy, two enemies, or a whole enemy team, then lastly, shoots an icicle straight at their heads.
