Gigan vs. Twilight Sparkle

Gigan vs Twilight Sparkle is a 2020 spin-off film of  My Little Pony: Friendship is Magic: The Lost Adventures movie "Gigan vs. Twilight Sparkle.

Plot
Twilight (or so it seems) emerges from Mount Everhoof and begins a destructive rampage. Discord, usually Twilight's ally, confronts her only to be mutilated and forced to retreat, but not before inflicting a wound that exposes something shiny and metallic beneath Princess Twilight's skin. Princess Twilight's rampage continues, but another Princess Twilight arrives and the two begin to fight. Soon, the challenger is revealed to be the true Princess Twilight, while the other turns out to be Gigan, a robot armed with advanced weaponry. The real Princess Twilight is severely wounded but inflicts some damage on the machine; both the Alicorn and the Kaiju retreat hastily. Starlight Glimmer hypothesizes, based on Gigan's advanced technology and composition of unearthly metals, that the robot is a Changeling super weapon. Meanwhile, Princess Twilight arrives at her castle during a thunderstorm and is struck by lightning multiple times, seemingly reinvigorating her. The Changelings's leader, Queen Chrysalis, helps to repair the robot. Then, Queen Chrysalis dispatches Twilight Sparkle to destroy Gigan. Twilight appears shortly afterwards. Trixie and Twilight fight together, but they are no match for Gigan's vast array of weapons. Eventually, Princess Twilight uses the electricity stored in her body from the lightning to create a magnetic field that ensnares the robot, then removes his head, shutting off his controls.
