Tirek towered over Ponyville, maniac laughter of victory filled the air when one princess, whom he had not heard of stepped forward.
 
"What's this? A fourth foolish alicorn step forth to oppose me?"
 
Twilight smirked.
 
"Not just an alicorn, a princess, and as a princess, I have access to all the resources and people of Equestria for its aid!" Twilight retorted.
 
Tirek laughed mirthlessly "And what resources are those? All the power of the princesses combined? The power of friendship?"
 
"Ye- no- Well, No on the first one, second one, you might say that." Twilight took out a radio and clicked 'on'. "Commence the attack."
 
Before Tirek even knew what hit him, several dozen and different kinds of missiles hit him at super sonic speeds and detonated in his face. Bombs were dropped right on him from far beyond his sight, and to add insult to injury, ancient plane ponies swooped in for attack runs with dated machine guns
 
"W-What sourcery is this?!"
 
"The sorcery of American, German, British, and several other national standards of engineering!" Anon whooped from within the cockpit of Blitz as a second attack run was made.
 
Tirek recovered just enough to see the barrels of the GAU spin up and then his world exploded into agony.
 
Later, atop Tirek's bullet riddled and mangled corpse, Twilight steps up to the aerial fleet. "Hey, nice work on Tirek, guys. Thanks for the help."
 
"It was nice to actually be allowed to do something during a crisis like this." One of the hornets waved off.
 
"Yeah, any idea why Celestia's always forbidden us from combat work before?" The A-10 mare asks.
 
Right as a charred, bullet riddled arm loses it's fight with gravity and falls away to splatter onto the grass.
 
"No idea." Twilight shrugs with a smile. "But you can bet as princess, I'll be making great use of you guys. All of you are now being hired as my personal, royal guard!"
 
Twilight enters the chamber of chairs where her friends are seated "Good news, everyone! I found us a new guard for my kingdom, and I'm having them line up so we can each pick three as our personal guard!"
 
"Call dibs on tha A-10!" Applejack chimed in happily.
 
Later...
 
Celestia, Luna, Cadence, and Twilight are in a meeting together along with their guards, all but Twilight and her guard fidgeting.
 
"T-Twilight, my most faithful student?" Celestia stutters.
 
Twilight happily and obliviously blinks. "Yes, Princess, are you okay? Is something wrong?"
 
"Well, it's just... Your new guard is making us nervous."
 
"I'm sorry, Princess! I didn't mean to, daddy says that's just, sort of what happens around me..." Morgan apologizes while Warthog gives Celestia an unsettling stare from behind Twilight's back.
 
"Oh, don't worry, princess! the plane ponies are all perfectly friendly!"
 
She says as in a window outside, t-50 gestures to Celestia, Cadence, and Luna then proceeds to thrust his hips at the air.
