Celestia took a deep breath “The Crystal Empire contains incredibly powerful magic, if it is filled with love and hope so will Equestria but if Hate and Fear take over bad things will happens, a dark unicorn took over the Empire and wanted to spread darkness throughout the land. It lies far in the Frozen North” Pinkie flinched for a split second but no-one noticed.

Twilight/Frisk frowned “I assume you wanted me and the girls to go there to defeat this Sombra somehow.”

Luna nodded “We also planned to send Cadence and Shining Armour as well. Cadence is descended from Princess Amore their former ruler.”

Cadence shouted “What we were about to get married and now we have to do this?!”

Celestia shook her head “The empire returned earlier than I expected, something must have weakened the seal.”

Twilight/Frisk grimaced “Probably the power I let out broke the weakened seal. I will go and put this Sombra

Rainbow grinned “I’m game.”

Applejack nodded “I’m coming with as well, I screwed up once before.” Rarity and Fluttershy nodded as well.

Pinkie frowned “I will go too, I have been a really bad friend and it shows. I’m sorry Frisk for everything.”

Twilight/Frisk gave Pinkie a light hug “Thanks Pinkie, I forgive you. You are really sorry.”

Pinkie shook her head “You have no idea of what I’ve done to you and for both our sakes I hope you never will. If you do we may never be friends again.”

Twilight/Frisk nodded “I assure you nothing will get between us, you’re a friend Pinkie.”

Cadence grimaced “Fine we’ll go but I want a proper wedding when I get back.”

Shining Armour nodded “I will protect her with my life, we will return once we have defeated King Sombra.” The group left taking a train heading north, everyone else was quiet as Pinkie and Twilight/Frisk were looking at each neither flinching for a moment.

The train stopped and the group got out. Rarity complained as the marched through the snow “I wish I brought a scarf, it’s freezing.”

Rainbow was putting a wing over Fluttershy to keep her warm. Shining Armour and Cadence were leaning onto to each other. Applejack, Twilight/Frisk and Pinkie were storming ahead when a dark blast of magic slammed into the ground.

Dark shadow form with a large red horn roared it’s green glowing with dark magic “CRYSTALS!”

Twilight/Frisk grinned as she began swinging her knife at the monster “Die, King Sombra!” The waves of determination started to push the Dark King back, until it roared a pitch black board appeared behind the King that read LV 400.

Twilight/Frisk's was launched back by a huge wave of crystals, she landed on her feet. She growled as she fired a blast after blast of determination at the dark king, Cadence looked at Shining as the Dark King shrugged off everything“We have to do something! She is losing, we must help her!”

Pinkie nodded “I’d hate to steal Frisk’s thunder but she needs my help. I just hope she forgives me for what I’ve done.”

Pinkie stood up on her hind legs, her front hooves elongating slightly forming hands. Her back hooves elongated ending in feet, her pink mane changed in a way similar to Twilight/Frisk’s forming a brown mop that change to pink half-way down.

She was wearing a pair of brown boots nearly up to the knee with light purple leggings underneath as well as a torn pink skirt as well as light purple turtleneck with a large light pink stripe at the bottom she turned around her pink eyes gazing upon her other four friends as well as Cadence and Shining Armour.

Twilight/Frisk was starting to tire, she blinked in shock as a pink spear slammed into the beast. Pinkie in her transformed ran up to her with a smile “You okay.”

Twilight/Frisk eyes widened “Betty?!”

Pinkie/Betty frowned “I know we have a lot to talk about, and I have a lot of apologies to give but for now I have to take down that bastard.” Twilight/Frisk nodded.

Pinkie/Betty leapt forward swinging a pink scythe tearing into Sombra, Sombra tried to blast her with magic only for a pink shield to block the spell. She leapt over him cutting a small part of his horn off with a swing before firing a huge pink blast obliterating the dark king. Pinkie/Betty yawned “Well that was boring” she clicked her fingers summoning a milkshake.

She then saw the horn fragment and crushed it, Twilight/Frisk stood up as her LV jumped from 90 to 490. The pair rejoined the group, Pinkie/Betty smiled “I suppose you should know my name before I cam here, I am Bête Noire also known as Betty.”

Rainbow growled “So you were here all along, give me one reason I shouldn’t kick your ass?!”

Pinkie/Betty grinned “Dashie, do you really think can? I beat a being that even Frisk couldn’t despite the fact I am holding back right now.”

Applejack pulled Rainbow back “Pinkie's telling the truth she…”

Twilight/Frisk shouted “Betty, you were Pinkie all this time! How?!”

Pinkie/Betty rolled her eyes “Chara managed to overcome me after you left. I must admit I never thought I would see you again. It hasn’t even been a years since we met in this world.”

Twilight/Frisk frowned “Wait how do you remember me? I was erased from existence remember.”

Pinkie/Betty laughed “Do you really think I am so weak as to be effected by such power, I simply didn’t care who it was as long as I could beat them.“ she then frowned “ I can help you control your violent tendencies, I learned how to do it a while back. Are you willing.”

Twilight/Frisk nodded “Of course, I don’t want to go crazy and kill everypony.”

Cadence frowned “You can chat on the way, we need to locate the Crystal Empire before we freeze to death.” They nodded as the six bearers of Harmony following Cadence and Shining Amour towards where the Empire was supposed to be.

Many wanted Spike to be Sans but due to what I'm basing this off I couldn't. I came up with the idea you see in the chapter, I hope you like it.
