The sky above Ponyville was split by a rainbow trail as a familiar cyan pegasus flew overhead, busting clouds with powerful kicks. Once the sky was cleared up, the one and only Rainbow Dash, marefriend of Wonderbolt Soarin, and due to become one herself, landed on a cloud and lay back with a content sigh. "Life is good," she muttered as she started settling down for a nap. Only for a familiar yell to pull her from it.

Down on the ground, Scootaloo, Apple Bloom, and Sweetie Belle; better known as the Cutie Mark Crusaders, were once again being harassed by local bullies Diamond Tiara and Silver Spoon. Though their tormenters had somepony else with them today: a powerfully built earth pony with blue fur, and a fist for his cutie mark.
"This is my new bodyguard, D Muscle," Diamond Tiara said while gesturing to the silent pony with a foreleg. "Daddy hired him to look after me and do whatever I tell him to do. "D Muscle, break that scooter!" she ordered while pointing to Scootaloo's favored mode of transport.
"Stay away!" Scootaloo yelled, holding onto her scooter in attempt to protect it.
Before D Muscle could do anything, he felt something tap the side of his head. Turning to look at it, he saw Rainbow Dash hovering beside him.
"Yo, what's up?" Dash asked with a grin.
"Rainbow Dash!" The Crusaders exclaimed together, happy that Dash had come to help them.
"So... picking on Scoot and her friends," Rainbow Dash started as she moved in front of the three fillies. "Not cool. You want that scooter, you gotta go through me."
"Move, pegasus," D Muscle said in a voice that didn't suggest intelligence.
"I don't even know where to start with you. Do you have any idea who I am?" Dash asked. "Any idea at all, who I am?"
D Muscle turned and tried to buck Dash with a powerful kick, only for her to avoid his attacks one after another.
"Basically, kind of a big deal," Dash said as she wrapped her forelegs around his neck from behind.
D Muscle yelled as he tried to get her off.
Dash held on while admiring her muscles. "Aw that's beautiful. Yeah... that's the stuff."
D Muscle didn't get her off until she let go and went back above him.
"You listening?" Dash asked. "Okay. Grass grows, birds fly, sun shines, and dude... I hurt ponies." She then zipped down and bucked D Muscle in the chest. "I'm a force of nature!" a buck to the face. "If you were from where I'm from, you'd be bucking dead!" a final buck to the chest for the knockout before Dash landed on D Muscle's unconscious body, looking at Diamond Tiara and Silver Spoon with a scowl. "Beat it."
The two bullies nearly tripped over their own legs as they ran away as fast as they could.
"Rainbow Dash is the coolest pony ever!" Scootaloo exclaimed as she and her friends surrounded Dash.
"Was there any any doubt?" Dash asked with a grin.
