Double Alicorn.

"Pinkie! How did you survive," Dash questioned Pinkie with the ferocity of a cougar.

"It is not by my hoof that I am once again given flesh," Pinkie replied," I was brought back by ponies who wish to pay me tribute."

"Tribute? You steal mare's souls and manipulate their bodies."

"Perhaps the same could be said of all religions."

"Your words are as twisted as your soul."

"What is a pony? But a miserable pile of secrets, but enough of this, let us begin."

Pinkie and Dash rushed at each other, locking horns in a struggle for dominance. Unfortunately for Rainbow Dash, Pinkie, being a triple alicorn, had an extra horn, and thus was better. Pinkie threw Dash and sent her hurdling toward the ground. Dash unfurled her wings just before she hit the ground in an effort to soften the impact. It didn't work, and Dash crashed into the found. She shook herself off and looked up to see Pinkie charging her, Pinkie's six wings allowed her to reach alarming speeds.

Rainbow Dash fired double alicorn lasers at Pinkie, but she simply dodged them and hit Rainbow Dash head on, leaving a massive crater. Pinkie began to slowly fly away.

Dash was very dizzy, and her vision was blurry. She began to see cheering crowds and flashing lights. Suddenly, a scruffy looking pony appeared in front of her.

"Get up Rock," the pony said," get up you son of a bitch!"

Dash slowly rose to her her hooves, growing two more horns and another two sets of wings, becoming a quadruple alicorn.
She turned to Pinkie.

"Hey," Dash yelled, Pinkie turned to Dash," I didn't hear no bell."

Pinkie charged Dash again, but this time she ran right into a left hook that knocked to the ground. Pinkie rose to her hooves and she and Rainbow Dash began trading blows in a vicious tango of flying fists and magical explosions. Pinkie threw dirt in Dash's eyes and kicked her to the ground. She tried to stomp on Dash's head, but Rainbow Dash rolled out of the way, grabbed Pinkie's hind legs and pulled them out from under her. Pinkie fell face-first onto the ground. Rainbow Dash then put Pinkie in a figure four leg lock.

"Oh my god! Dash has cinched in the figure four! Will Pinkie tap," Jim Ross yelled into the microphone that was there the whole time,"Oh! Pinkie's reaching for the ropes, it's just too bad there aren't any ropes to grab seeing as they're in an open field!"

Rainbow Dash held Pinkie in the figure four for three days before Pinkie finally tapped out and conceded defeat. Pinkie flew away before Dash's guards could arrest her, but Dash was happy, she had defended her beloved land for another day.
