"I may know about a lot of things, but friendship isn't really one of them. And I'm definitely not going to learn more about it by being alone all the time."

Twilight is in the women's bathroom located at the Arizona Inn in Tucson, Arizona. She is applying lipstick when all of sudden, Adam Lyon's rival Chad (Tom Kenny) bursts in. He attempts to kick Twilight, but Twilight dodges, resulting in Chad accidentally destroying a mirror in the process. A brutal fight between them ensues, but is unseen and the force of the blows are powerful enough to destroy another mirror just outside the women's bathroom. Twilight emerges from the women's bathroom afterwards and walks away, victorious and seemingly unharmed. It is then seen that she has finally succeeded in killing Chad and childishly drew all over Chad's face with her lipstick.

Ending description 3
A magenta Toyota van rolls up by a mansion. Twilight looks out the window anxiously. An hour later, Twilight breaks into a drug lord's mansion and violently attacks him. The unnamed drug lord points to a mahogany table with a photographs of Draco Malfoy's parents Lucius Malfoy (Jason Isaacs) and Narcissa Malfoy.
- Magic Blast: Twilight shoot a magenta ball of energy at her victim.
- Flipping Heel Kick: Twilight flips forward in a circular motion, bringing her feet over her head kicking the victim and then landing back on her feet.
- Flying Punch: Twilight launches herself forward with a series of punches to the victim's face.
- Carnival Spin: Twilight spins backward and kicks her opponent in an impossible fashion.
- Brutal Kicks: Twilight violently kicks her victim's stomach, lodging her foot in her victim's intestines. She keeps it there for a second before pulling it out, then kicks her victim's forehead, causing it to explode like a balloon. (Equestria Girls: Lethal Alliance)
- Savage Beating: Twilight repeatedly strikes at the torso and head of her victim very quickly, and then stands, striking a pose. The confused victim then screams in pain a few seconds later and explodes in a shower of gore. This fatality seems to borrow from the Asian martial arts study of pressure-points.
- Kick and Destroy: Twilight walks up to her weakened victim and with one swift uppercut, knocks her victim's head straight into the air. Twilight patiently waits for it to come back down before she kicks it hard at her victim. When the head strikes them, they explode into piles of blood and bones.
- The unnamed drug lord in Twilight's third ending somewhat bears an uncanny resemblance to Dudley Dursley (Harry Melling) or Bradley "Brad" Morton (Matthew Nolan) from American Dragon: Jake Long (2005-2007).
- In Equestria Girls: Deception and Trickery, Twilight Sparkle's third outfit is based on Velma Dinkley from Scoooby-Doo series.
