* Rainbow Dash's [[WeCanRebuildHim cybernetic transformation]]. In the first episode, she gets badly injured in a confrontation against [=DISCoRD=] that leaves the walls and floors splattered with her blood. Then, in TheTeaser of episode 2, she's shown with tubes implanted in her body, [[EyeScream her eyes removed]], and her legs replaced with mechanical prosthetics; the sight of her grotesque condition is enough to make Nurse Redheart comment that she looks even ''worse'' than when she was brought in. The worst part? The anesthetics given to her by the doctors barely had any effect, meaning [[AndIMustScream she's not only conscious throughout the whole operation, but she can feel every second of it]]. And in TheTeaser for episode 3, we're treated to a couple of second-long flashbacks of her screaming and writhing in agony as her new eyes are being added, shown on top of her surveying her new metal-clad form for the first time, on the verge of snapping completely... [[spoiler:'''''[[MoodWhiplash Cue happy opening titles!]]''''']]
* Pretty much '''all''' of episode 5, [[spoiler:namely the flashback of the fall of Canterlot]]. About the ''first thing'' that happens is [[spoiler:Fluttershy being bloodily attacked, paralyzed and nearly eviscerated by a changeling]]. Much of the rest is just [[spoiler:changelings and ponies ''very'' gruesomely killing each other off]], including [[spoiler:Chrysalis basically [[Film/TheEmpireStrikesBack Force-choking]] [[YouHaveFailedMe her subordinate to death for failing to take Canterlot Castle]], literally ''[[AndShowItToYou ripping out Shining Armor's heart]]'', and snapping off Twilight's wings]]. We also get additional doses of Rainbow Dash's previously described BodyHorror [[spoiler:as she is repeatedly injured and self-repairs during the battle]]. That ContentWarning at the beginning? It's '''not bucking kidding''' this time.
