Following the disastrous Fall Formal, after Sunset put on Princess Twilight's crown, a massive blue beam shoots into the darkening sky, accompanied solely by the moon's glow. Students, including yourself, rush to the school's entrance and watch in awe as Sunset Shimmer is lifted into the air, transforming into a full-fledged demon.

Demon Shimmer: "Finally! It's about time."

The girls (Twilight, Applejack, Fluttershy, Rainbow Dash, Rarity and Pinkie Pie) scrambled to the Wondercolt Statue as you watch with the students. You can feel the sinister aura radiating consistently from Sunset. A small red bead of some other entity within. Then, some dude speaks up

Zach: "You're not Sunset. You're just a parasitic formless soul. What did you do to the real Sunset!?"

Demon Shimmer: "Idiot, i am Sunset's dark side! Regardless, Once I find the remaining residents of this school, I will take Equestria by storm, and once I complete that, I'll go beyond!!"

Demon Shimmer activated a dark fiery aura, frightening the girls some.

Zach: "I've had high stress levels, building anxiety, and emotional struggles for three years because of a DEMON?!?!" He removes his pin from his vest, take the vest off, pin his pin on his shirt, remove the tie, unbutton the button for the tie, and toss the tie and vest on the cement near him. (Why is bro taking his top off? Showing off muscles?)

Mane 6: "Zach! What-" Blushes when they see Zach's muscles "Oh My..."

Student 1: Rolls his eyes "Oh brother, Zach is one of those guys who think they're HIM for real, stop aura farming."

Principal Celestia: Confused "What?"

Zach: "I love your work Rarity, but this demon has been a thorn in this school's side for far too long, and maybe longer for Sunset. Whatever the case may be, it just. Got. PERSONAL. "

Zach lets his Fire aura loose to the point of consistent visibility, which had a huge contrast to the demon's black flames with red outlines. Zach's fire was green with white edges

Demon Shimmer: Rolls her eyes "Fuck off, Mr. show off." Fires a death beam at Zach

Vice Principal Luna: waves some dust away "Wow"

Zach: "Hmph" Dodges

They fight, while you and your fellow students watch. They be going back in fourth, seemingly equal in power
