Nightmare Fuel: My Little Portal
Rainbow Dash's 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 The Teaser of episode 2, she's shown with tubes implanted in her body, 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 she's not only conscious throughout the whole operation, but she can feel every second of it. And in The Teaser 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... Cue happy opening titles!
