Equestria's Supreme Commander

So, it was the next day, and Luna and I, inside our ACUs-which were connected to a Dragonfly transport-were on our way to the volcano in which she and Celestia had imprisoned the Seraphim ACU two thousand years ago. "So, is there anything political I should worry about?" I asked.

"Not likely," Luna said. "The area around the volcano is mainly Equestrian territory, with just a small part of it being in Zebra lands. Still, if what you said about Zebras attacking your southern base is true, than they may try to take it back. With aggression if needed."

"Then we may need to keep the weapons on these ready," I said as I did so, but keeping the chest laser deactivated. "After all, they have potions that are volatile on the level of strategic bombs, which can destroy an ACU in just a few hits."

"As long as we use those as a last resort," the lunar alicorn replied.

"Don't worry, that's what I'm hoping for," I replied. I checked the main monitor on my ACU, and saw a large mountain in the distance. "That it?" I asked.

"I believe so," Luna replied.

"Right," I said. "Setting us down now." With that, I typed in a command for the Cybran transport to set us down and release the latches holding the ACUs on to it. As we dropped to the ground, the shock absorbers in the legs of the ACUs took the impact, and, after the legs straightened, the two of us began making our way toward the mountain.

"Do you have anything on overwatch?" Luna asked,

"A spy plane," I replied. "Better safe than sorry."

"I suppose that will have to do," Luna replied.

"Yep," I said a we reached the base of the mountain, which towered above our ACUs. "So, where would the Seraphim ACU be?"

"I would imagine near the base," Luna replied. "Josh, if I may ask, why did you not bring Twilight along?"

I chuckled. "You're kidding, right?" I said. "Twilight coming with us on an expedition to find a lost, alien ACU? We may be in a relationship, but I don't want to be blown up just because she couldn't resist finding out what a button did."

"I suppose that is fair," Luna said. "But I thought an ACU could survive another's explosion."

"Yeah, but we may be going into magma, which will weaken the armor integrity to where they could be destroyed by a lucky shot," I replied. "Like I said: I don't want to be blown up."

"Ah," the lunar alicorn replied. "So, how do you propose we get up there?"

"Really?" I asked, turning my ACU's head to Luna's. "We're in giant robots that can traverse miles in a matter of minutes when on foot. We walk up there."

With that, I had my ACU lead the way up to the top of the mountain, with Luna's UEF ACU following close behind. I should point out that her ACU had dark blue-akin to her skin- as the main accent, with silver is the third color. It also had each of the upgrade parts, but I don't know what the specific upgrades were short of the shield I saw shimmering just above her ACU's armor.

After a few minutes, we made it to the top, where, to our surprise, the top layer of the magma-I don't know what it's called, honestly-was broken, with nothing coming out. "Oh, shit," I whispered to myself before typing in a few commands for one of the constructor drones stored in my ACU's back. It detached, and made its way inside the hole, lighting it up as it looked around.

"Did you find anything?" Luna asked as the drone returned ten minutes later.

"No," I replied. "Nothing in there. No ACU, no magma, nothing. That leaves two possibilities. One is the original pilot teleported out-"

"-Or my sister has already retrieved it."

Loyalist camp-Celestia-3rd

There was a flash of light as the Seraphim ACU, piloted by Celestia herself, arrived just outside the Loyalist camp, casting a large shadow over all there. The numbers of the Loyalists had expanded since taking Rarity and Sweetie, now consisting of farmers who were afraid of Nightmare's corruption and Eternal night returning. unicorns with promising magical capability, and most of the Wonderbolts. All but the farmers and the original group had been corrupted and brainwashed by Celestia's forces.

It's a good thing that the lord who previously piloted this was able to upgrade it before he joined the Way, Celestia thought, as the ACU had an Engineering suite equivalent to a tech three engineer unit, a teleporter, and a range and rate of fire upgrade for the main weapon. Now, we may cleanse Equestria. And with that, Celestia began to construct her own army, starting with a Gateway so as to contact her lords, and summon more ACUs for her followers.
