Frisk has killed everyone and is possessed by Chara. They walk down a corridor and see Don.
Don: Hi kid. So… you killed everyone that I cared about. You killed them all. YOUR SINS SHALL NOT GO UNPUNISHED!
The fight begins.
Voice: Don blocks your way.
Don: It's a beautiful night outside. Birds are sleeping, crickets are chirping. On nights like these, kids like you… SOULD MORE THAN BURN IN HELL.
Don throws lots of rocks, fire, tornadoes, and lightning at Frisk who dodges them. Frisk presses CHECK.
Voice: Don 2 Attack 1 Defence. You are in a heap of trouble.
Don: It's telling the truth.
Don fills the text box with water. Frisk dodges the debry and attacks. It hits.
Don: GAAAAAAAA. heheheheheheheheheheheHE! HEHEHEHEHEHE!
Don laughs normally and gradually goes to a crazed lunatic laugh.
Don:HAHAHAHAHAHAHAHAHAHA!
Dons HP goes down a sliver.
Don: As Undyne would say…
Don makes a face similar to Undyne's face.
Don: … "YOU'RE GONNA HAVE TO TRY HARDER THEN THAT!"
The true fight begins.
