As a Moments subpage, all spoilers are unmarked as per policy. You Have Been Warned.
- The snowplow that rams into the car (where Cady and her parents were in) at the film's beginning. We get to see Cady's perspective as she witnesses her parents' death.
- The M3GAN prototype having a demented expression because her face is stuck while making a "confused look".
- Brandon bullying Cady while they are alone in the forest. If M3GAN did not intervene, who knows what else he would have done to Cady?
- In a following scene, Brandon dishes out abuse to M3GAN by throwing her to the ground, removing one of her shoes, and straddling her body. Judging from his position, it is implied that he was going to do something much worse than just breaking her.
- The thought of what Brandon likely would've gone on to become if M3GAN hadn't killed him is chilling by itself, given he seems to be a budding sociopath and rapist. M3GAN very well may have saved the world at large from a future Serial Killer. Worse than even her, at least.
- And, in itself, M3GAN's mistaken belief that all school bullies grow up to become monsters shows that she was always going to start killing indiscriminately out of misguided thought that anything could potentially present a threat to whoever she saw as primary user. In fact, she obliquely justifies her own actions to Cady that way.
- After Brandon tries to make M3GAN respond to him, she grabs him by his ears and stretches them out until one of them rips off. She then gives him a headstart... before getting down on all-fours and chasing the older boy until he rolls off a hill onto the open road where he is immediately run over.
- M3GAN is not only more than willing to kill for Cady's sake, but seems to get a sick pleasure out of it, as seen as she tauntingly scolds Brandon.
- M3GAN has the ability to mimic voices and uses it to lure Celia's pet dog and kill it offscreen. When Celia tries to find her dog, she gets drawn to the shed where M3GAN impales one of her hands with a nail from the nail gun and then sprays high-pressure pesticide at her. While the effects are not seen in the original cut, the uncut version reveals most of Celia's face melting away due to the chemicals.
- After M3GAN's infamous dance scene, she rips the blade right off a paper cutter and stalks David through the Funki building's hallways as he runs for his life.
- She's only ominously walking after him to comedically contrast with David tripping over himself and scrambling to get away.
- Considering her speed when she galloped after Brandon on all-fours... it's abundantly clear that she could have caught David at any time, and she was just toying with him.
- And then there's Kurt, who saw M3GAN stab David right in front of him... he gets sprayed in the face with blood.
- Kurt is cornered in the elevator with David's corpse, with M3GAN going into detail about how she will frame him for the murder-suicide. M3GAN then forces Kurt to hold the paper cutter blade to his neck as he is unable to resist against her Super-Strength.
- In the unrated cut, she slices his neck first.
- The next we see of David and Kurt is when their corpses are unveiled to a public gathered for M3GAN's official unveiling, leaving countless innocents and children traumatized as she uses the distraction to make her way back to Cady and Gemma...
- M3GAN easily overpowers Gemma while they talk in the kitchen. The android then whispered to Gemma that she will literally rip her head off if Cady walks in. Gemma is forced to cooperate with M3GAN to ask Cady (who heard the commotion in the kitchen) to go back to bed.
- Gemma splashes M3GAN in the face with water. It seems to work, as the doll freezes in place after short-circuiting... but M3GAN starts moving again... her movement being jerky and more robotic, but somehow faster.
- Near the film's conclusion, Gemma fends off M3GAN with a hedge trimmer and mutilates the android girl's face with it and tears off some of her artificial hair.
- M3GAN returns the favour by punching Gemma in the thigh and painfully ripping out some of the woman's hair.
- At this point Gemma asks M3GAN how she plans to continue living with Cady if she kills her legal guardian. M3GAN explains that she knows she can't kill Gemma, so she proposes an... alternative solution.M3GAN: But I have another emergent capability you probably haven't figured out yet. And that's palliative care. You see this pen? A short, sharp probe to the cerebral cortex would cause full-body paralysis, and could even cause the victim to bite off their own tongue. (Menacingly) Perhaps then you might appreciate just how useful I can be.
- Cady uses Bruce to swing M3GAN around like a ragdoll, and then rip her in half. We get to see the android get ripped apart in gruesome detail. Feeling betrayed, M3GAN immediately abandons her prime directive and turns on Cady.
- While M3GAN is distracted with going after Cady, Gemma quickly bashes the android's head in, and graphically dismantles her face. This includes removing her eyes and face-plate.
- Despite all of that, M3GAN is still alive and savagely attacks Gemma until Cady manages to stab a screwdriver through the android's exposed CPU.
- Even with her memory processor destroyed by the screwdriver, the film indicates that M3GAN escaped termination by downloading herself into the Elsie interface.
