The Princess Of Death

Nightmare Moon said to Dashie, "I am going to kill all of the failed pegasus ponies."

"Wait, could I help you? I could kill them more  brutally." Ranbow Dash offered.

Author: Rainbow Dash didn't want to kill them brutally, she is killing them quick.

So Nightmare Moon gave Dash a factory of her own to run herself. Now lets make fake ponies, and let the real go. Dashie painted them, crushed them, and made them into rainbows. She went to Nightmare Moon.

"Now lets have one of the professionals kill you." Nightmare Moon said before Rainbow blacked out from sudden pain.
