chapter 1: The girls agree to team up
Princess Twilight Sparkle shook hands with North. "Then we have a deal."
"Come on!" cried Sunset, grasping her red-gold hair in panic. "We only have 3 days to stop them before Twi, Gloriosa, Princess Luna, Juniper, Pony Fluttershy, Pony Rarity, Stygian and I all turn into our demonic forms forever! We need to chase Pitch and stop him!"
"She's right!" called Pony Rainbow Dash, beating her wings. "Come on, guys!"
They ran, chasing. "We'd better split up!" called Human Rainbow Dash. "We'll take the human world villains. Princess Twilight, you lot take on your villains. Then that leaves the rest of you on Pitch. Who's with me?"
Twilight raised her eyebrow."Rainbow Dash, that's a terrible idea."
"Is not!"
"Is too!"
"Is NOT!"
"Is TOO!"
"STOP!" cried human Applejack, holding up her hands between Twilight and Rainbow. "We don't have time fer arguing! We have to stop them before our worlds get ruled by villains!"
They ran, separating out to their targets. "Remember your signals?" called Princess Twilight, showing a flashlight.
"Yes," replied Sunset, holding her journal. "We should run."
They chased their targets, the EGs on the trail of the old villains and the mane 6, Starlight, Discord and many others on the tail of their villains.
