The Marvel-ous World of Ponies

Rainbow Dash took a hard, tumbling landing before gaining her bearings and stopping herself from rolling further. Pinkie Pie landed perfectly on her feet and said to her friend, "Hey, Dashie!"

"You have no idea what you're dealing with, Pinkie." Rainbow Dash told the mare who knocked her out of an important conversation, not amused.

"Hm," Pinkie thought, observing her surroundings, "Playwright in the park? Doth it be 'cooleth' to weareth mother's drapes?"

"I have come to take my brother back to Ponygard."

"If he gives up the Alicorn Amulet, he's yours. Until then, stay out of this," Pinkie said, putting her mask down and walking away, "Tourists, I swear-", Pinkie was cut off by a thrown god-hammer, "Okay, if that's how it's gonna be, Dashie." And then they fought. Until Captain Applemerica stopped them, that is, "Settle down! I've never seen you two fight like that. And I never should, either. You're friends. We're friends. Remember?"

"Well, do you remember how we all kind of disbanded?" Rainbow Dash asked angrily.

"And," Applejack responded, "I don't quite know why. So tell us why you're here, we can help."

"I've come to stop my brother from destroying Equestria." Rainbow Dash answered.

"Okay then, prove it." Applejack ordered, "and put the hammer down."

"Bad call, Applejack! She loves that-" And then Pinkie was sent backwards a couple yards.

"Want me to put the hammer down?" Rainbow Dash asked, rhetorically as she charged at her friend, who raised her shield in response. The result was the answer to a long asked question: what happens when an unstoppable force meets an immovable object? Loud noise, and a change in direction for the unstoppable force.
