Utopian Harmony Empire.
Canterlot Headbit Base.
Inside the medical station, a anthro pony captain named Shining Armor and two of his guards enters the station. The captain didn't look happy when he saw multiple civilians & soldiers were all waiting to get checked up on their bruised bodies and missing limbs, even a few soldiers have died from losing too much blood.
Sighing, he turns his head to see a cadet messenger saluting to him.
"Report, how's the conversion progress in the human world?"
"I'm not sure captain, we've gotten reports of taking more human lands a few days ago and succeeded. However, two of our squads were ambushed by something else that's not human nor pony. Only four ponies were still alive and wounded, the others are confirmed to be all dead. The one responsible for this is still out there."
Gritting his teeth in anger at this report, Shining slammed his fist into a wall. Making the cadet and his guards flinch at his unexpected reaction. Calming down, he looks at his messenger.
"Dammit, it's the ninth squad we lost so far. I better go report this later to my majesty, she won't be very happy. For now though, lead me to the surviving team cadet. I need to speak with them."
"Yes sir!"
While the Shining is pondering over on what to do next, something else is going on outside the base. In the Canterlot Garden, a stone Draconequus statue named Discord is quietly laughing from feeling and hearing the distortion of both harmony and chaos going out of control.
"Oh little Sunbutt, how the mighty have fallen. Once a beautiful pony who endured countless years of suffering, now became something far worse than Equestria's past time of villains."
Discord uses both of his eagle and lion hands to slowing get them ready.
"You forgot a few fatal mistakes of your devious plan. You may have used your element pawns to seal me a second time for good, but I have a fail-safe plan. In case something were to happen with Equestria and other countries around the world. Since Harmony's knights turned dark, then why not Chaos's knights turn to light as well?"
With a snap of both fingers, his whole statue body begins to fall apart.
"Enjoy your "PEACEFUL HARMONY" times Tia cause it'll be the last you'll ever see it again."
Discord made one last maniacal laugh before his whole statue body collapses to the ground.
Ruins of New York City.
Utopian Harmony territory.
35 hours earlier. . .
On a rainy night at 8 p.m., three U.S.A. marine soldiers are nesting in the 15th floor of a bank building. They were stationed there by one of the commanders in order to find out how many pony soldiers there are, look for any survivors not converted yet, and collecting Intel on finding a way to push back the barriers.
The first one is Wilson, Sargent leader of his squad called Molar.
Second is Piers, a scout sniper to detect enemies at long distances.
Last one is Aurora, a medic officer to tend the wounded, whether they be ally or enemy.
Both Wilson and Aurora are checking on their gears while Piers is at prone position near a broken window with his silencer sniper rifle out. He looks in the sniper scope to see no signs of survivors or enemies, until he spots multiple figures of pony soldiers.
"Sarg, I got eyes on four enemy patrols sighted at 12 o'clock on the streets, several miles away."
Hearing this, Wilson and Aurora take out their binoculars to see the enemy. All three of them spot each of the patrols splitting up different directions.
"Looks like both the patrols are splitting up, probably looking for any survivors in the city." Wilson said, watching the patrols carefully.
"You think any of them know of our location?" Aurora asked him.
"I highly doubt that Aurora."
Then suddenly, Piers looks to the left and spot a survivor surrounded by those ponies.
"Sarg, Aurora, I found a survivor at 9 o'clock near the collapse college ground. He's surrounded by those pony guards. Although for some reason, the kid's not running away, screaming, or calling for help."
They see one of the soldiers walk up to the survivor with a conversion potion.
"It's your call Sarg."
"Hold your fire Piers, we don't want to give away our location. Let's just wait and see if the other team can rescue him first before they convert him into a newfoal. Although, I just can't shake the feeling that something's very wrong."
The soldier stops in front of the survivor and opens up the bottle. Before going to pour the whole thing out, the survivor suddenly jumps at the soldier and begins to bite viciously at the neck. Both the humans and ponies were shocked of this sudden attack as the pony shook their heads and attack the human. The kid turns his head at the soldiers and jumps away. The ponies tried to attack at all sides with their weapons and magic, but surprising the kid dodges each of them as it tears apart and kills each of the soldiers, one-by-one.
The other patrol spots their comrades in danger and chargers at the enemy. Tearing the head off of a pony, the monstrous kid turns it head at the patrol and roars at them before killing off more ponies. Including breaking a unicorn's horn and tearing off both a pegasi's wings. Before going to finish off the remaining patrol member, a blast from behind hits the kid's back.
Turning around and roaring at someone close by, the murderous kid jumps high on a building and jumps again to move far away from the enemies as the other figure chases after it.
Back at the bank building, the Molar team were stunned in shock to see of what happened tonight.
"Wilson, what do we do now?" Aurora says, covering her mouth to not vomit.
Shaking his head, Wilson turns around and grabs his gear.
"Change of plans, we better go inform Headquarters and all four teams on what we just saw here."
Elsewhere, present time. . .
Outside of a closed school, a grown mare pegasi is walking while wheeling a human girl who isn't able to walk for a while. Both became good friends when they first found each other somewhere at a beach.
The human and pegasi look in the sky to see dark clouds largely forming in.
"S-Scootaloo, I'm scared." The girl says in a scared tone.
The girl's body relaxed when she felt two hands rubbing her shoulders.
"It's okay, I promise to protect you no matter what." Scootaloo whispers softly to her friend.
Scootaloo looks closer to see the barrier still engulfing each human lands as she glares at it.
'Damn you to the deepest depths of Tartarus, Celestia." Her mind said in a cold dark tone.
