 * 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.

 * 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.

 * 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.
