Manehattan

As Rainbow Dash charged towards the Red Comet with almost the same speed, Barbatos swung its sword mace. But the Red Comet used its dual axes to defend itself. The Red Comet used its boosters and pushed Barbatos at the side of a building, then punched at said Gundam, but it dodged its attack and punched the oppositions head. Barbatos then kicked the Red Graze to get away from the building so Rainbow Dash took to the skies.

The red mobile suit followed it, and started fighting in the sky. Few seconds later Twilight Sparkle teleported her and her friends plus princess Luna on top of a building and what they saw was one badly damaged Asteroth and a whole lot of destroyed Grazes, but no Rainbow Dash to be seen. "Oh I hope Rainbow is okay." Twilight said to herself.

"Twilight I know your worried, but I can assure you Rainbow Dash will be okay." Luna told Twilight.

"Shut up Luna! Rainbow is not okay! She's injured and battling a whole fucking army! Tell me does that sound okay?!" Shouted Twilight.

"Um, girls?"

"Rainbow Dash can take care of herself! She is not a little filly!"

"She just got out of the hospital missing her right wing because she can't take care of herself!"

"Girls..."

"Tis just a flesh wound!"

"A flesh wound bloody tartarus! Her wing is missing!"

"GIRLS!!!"

"WHAT FLUTTERSHY!!!???"

"Um... look up."

Twilight, Luna and all their friends looked up at the sky to see that there were two stars that look like they're dancing. The red one is zig zagging and the blue one looks like it's flowing around. They seem to crash and bang into each other very often, but little did they know that it was Rainbow Dash and Char Aznable fighting each other. "Wow Fluttershy that's the most beautiful thing I've ever seen." said Applejack.

'Applejack why are you so dumb?' Fluttershy thought

Then the blue star crashed down to the ground almost crashing into a building next to the Mane 6. Soon the girls realise that it was Barbatos that crashed into the ground. The red mobile suit then went back down to Manehattan to continue fighting Barbatos. However, the Devil of Tekkadan went straight back into the fight and swung its mace sword at the red mobile suit. Char dodged and swung one of it's axes into Barbatos shoulder but Rainbow shrugged it off.

Seeing Rainbow fight like that is almost barbaric was almost not equine. It was just so scary. Twilight used her still work in progress canterlot voice so Rainbow Dash could hear her and shouted "Rainbow let us help!!!"

"No." Rainbow told Twilight.

"Huh?" Twilight questioned.

"You'll get in my way." stated Rainbow.

Rainbow kicked the Red Comet off Barbatos, then removed the axe that was stuck on her shoulder. She now dual wielded her sword mace and the axe. But the Red Comet seems to have reinforcements because three Grazes just appeared out of nowhere like they didn't leave the city. "Sir, we'll take it from here." Said one of the pilots

"No! This is my fight and you'll stay out of it!" protested Char.

"Sir there no need to worry. It's just one mobile-" before the second Graze pilot could finish his sentence an axe was thrown straight to it's chest, killing the pilot as he gasps for air. "You talk too much." stated Rainbow Dash as the second Graze collapse to the ground. This scared the two remaining Graze pilots because of how relentless the Gundam pilot is. "AH HOW DARE YOU!!!" screamed the third pilot as he zooms straight to Barbatos while firing it's rifle. 'So annoying...' Rainbow thought to herself. Barbatos zoomed straight to the Graze firing its weapon and crushed its head with her bare hands, She the proceeded to stab the chest with her sword mace. Now there was only two left: the red mobile suit and a green Graze.

"Sir you need to leave now that thing is a monster!" proclaimed the last graze pilot.

"NO! You shouldn't even be here anyway. You must leave" commanded Char.

"But sir-"

"You have a family right? you need to think about them what would happen if you were to die?" asked Char.

"Y-your right... see you back on the ship, Char Aznable." And with that the last Graze pilot left. Hearing that name shook Luna's very core.
'Its been nine hundred years... How is he alive?' Luna asked herself. It was a name she thought she would never hear again. If he was truly alive and not some common name for this mobile suit pilot, then she would have to see him again one day. "Luna darling are you alright?" asked Rarity.

"I'm fine Rarity." replied Luna.

Everyponies faces on that roof look completely shocked. They have never seen Rainbow Dash do such a thing. What she was doing is nothing like her. It's as if she's a completely different pony.
"Twilight...um, I think Rainbow can handle herself just fine." said Fluttershy.

"Are you going to leave now?" Rainbow Dash asked Char. "All your friends are gone."

"No. I'm not leaving til I'm satisfied!" said Char.

Then the battle continued, the two mobile suits clashing for the final time and flew straight to the skies. With only one axe left Char had to be smart if he didn't want to lose it, so he defended himself from Barbatos sword mace. Barbatos didn't stop swinging its sword at the red mobile suit. It was barbaric to the point it was pure madness. Rainbow Dash swung the sword mace and in the end chops of the arm that's holding the axe of the red mobile suit.

Now, with no weapons and still not satisfied, Char kicked Barbatos in the chest but devil grabbed the red graze leg and threw him back to the ground. Char Aznable is now suffering from a head injury. Anymore hits from that mobile suit and he'd die. Char had no choice but to retreat. He personally thinks it's cowardly, but the mission wasn't a complete failure. Gjallerhorn got what they came for, and so Char went back into space.

Now with her job done Rainbow Dash went straight towards Gundam Asteroth with an unconscious Simon Rodgers on the inside, picking it up and carried him. With the mobile suit in her hands, Rainbow Dash and her mobile suit flew straight to Canterlot. Twilight and her friends were still trying to process what they just saw. It was the most violent thing they have ever saw.

"That... was... AWSOME!" shouted Luna.
