Equestria's Supreme Commander

"Wake up, you moron!" I heard from beside me, the yell jolting me awake.

"Ow, shit!" I yelled, rubbing my ears as I shot up. "The fuck was that for?" I asked, looking in the direction of the yell, only to see Luna, Twilight, Rainbow, and Applejack. "I was fucking sleeping."

"We know," Luna deadpanned. "That's why we were yelling: to wake you up. My sister-"

"Was trying to control me, I know," I said, getting looks of surprise from the mares. "What? She was in my mind, I kicked her out, simple as that."

"You defeated an alicorn in combat?" Luna asked, and I could hear the skepticism.

"Well, it was my mind and dream," I replied, shrugging. "I don't see why it isn't possible."

"Because any alicorn should be strong enough to defeat anypony in their mind," Luna said, to which I laughed.

"And to which you forgot I'm not a pony," I replied. "It also kinda helped that it was just her in there herself. Though I did see a shimmer of Rarity-"

"You saw Rarity?" Twilight asked.

"Either it was a dream version of her, or something else," I replied. "But what I want to know is how Celestia was able to get in my mind while I was asleep." I then looked at the lunar alicorn. "I thought only you could do that type of shit, Luna."

She sighed. "That is what is public," she said. "Celestia hid it for fear of the ponies going crazy over the possibility of being observed whenever they slept. The only reason I did it and it was known is because it falls under my rights as princess of the night."

"Though it would make sense for both of you to have," Twilight said, hand on chin. "I mean, some ponies are nocturnal, and because of that, you wouldn't be able to dream walk with them, so Celestia would have to." She then shrugged. "Not that those facts matter right now, but still."

"Yeah, um, it kinda does, Twi," Rainbow said. "I mean, it could mean she'll try to mind buck anypony who sleeps during the day. Which would be about anypony who naps during the day while they're exhausted or after work, or just ponies who get bored easily." She shrugged. "Just saying that if I was evil and had that ability, that's what I'd probably do."

"And we don't have a way to counter that, do we?" Applejack asked.

"None I can think of," I replied. "Which means she'll have free reign over the weak minded ponies, or those who don't know that they're dreaming. Anyone could become an agent." I rolled my eyes and sarcastically commented, "Fun."

"Which manes any who we let pilot ACUs will need to go through a lot of mental tests," Twilight said as she rubbed her forehead. "And since we don't know the full length of Celestia's skill, there's no telling how good those tests need to be."

"Well, strong 'nough to brainwash Rarity," Applejack said. "An' next to you, Twi, she's one ah the most organized ponies I ever knew."

"So we may very well be screwed," I said before an idea came to mind. "Hey, Luna, where's that mountain you and Celestia created when you faced off against that Seraphim ACU?"

"It should be located on our southern border with Zebrica," she replied. "I'm certain I'll be able to lead you to it. Why?"

"Nothing much," I replied. "Just. . . let's call it a hunch for now, shall we?"
