September 29th Manehatten police department rooftop

The pony and the changeling stood on the roof of the precinct, peering over the edge.

"It doesn't really matter to me who jumps first", Umbrella Agent Thorax replied in his cold muffled voice.

"I'll go"said Thorax.

Twilight Sparkle took a couple of steps back "Alright it'd be best if you got a running jump first", She suggested.

Thorax nodded and took fifteen large steps away.

"Be careful it's a narrow alley, but a pretty far jump" Twilight told him.

Thorax got into a running stance “1..2...Now!”

Thorax raced forward across the roof of the precinct in a really fast speed which amazed Twilight, as his right boot touched the brick edge of the building he jumped off it with all his might.

There was a moment of free fall as he sailed down the building. He landed roughly across the alley on the scaffold with a thud, now in a crouching position, the scaffold creaked and moved slightly but held up under the sudden weight.

Thorax rose to his feet and looked at Twilight and she had a worried and scared look "It isn't difficult princess Sparkle just wait a few moments while I get off this thing"

"Alright" Twilight called back and tucked her combat knife in her shoulder straps.

Thorax turned around towards a large window leading into the well lit apartment.

He drew back his metal covered knee and smashed it through the window and glass rained down into the dark alley below, Thorax then cleared out the remaining glass from the window pane with a few quick swipes of his gloved hoof he then placed his hoof on the window frame and pulled himself up and inside the apartment.

He activated his horn and began looking around inside the apartment to see if there's any zombies or bioweapons in there but there was nothing.

"Huh nothing here that's a good sign and it's a good thing that I didn't used my wings when I jumped here because if I did princess Sparkle would find out that I'm a changeling" Thorax said to himself quietly.

Then he turned and walked back over to the window and looked up at Twilight again on the opposite building.

"Okay your up princess Sparkle", He called up.

Twilight nodded nervously and took some steps back just as Thorax had done "Here goes nothing" Twilight said to herself.

Thorax watched as she ran towards the edge of the building. When she neared the edge she leaped off it gracefully and spread her wings then she glided and landed in the apartment.

"Phew wouldn't want to fall down there" Twilight muttered looking down the alley and saw many zombies had lurched away from the swarm at the front and into the alley and they were looking up at her.

"I doubt anypony would" said Thorax.

Twilight turned to the window in which Thorax stood then crossed the scaffolding.

Thorax reached out a gloved hoof which she took and he helped pull her up and over the high window frame. Twilight landed next to him inside the apartment.

Again the warmth of his glove against her cool hoof felt very welcome. Twilight found herself almost regretting when he removed it, she activated her horn and stood next to Thorax.

"Let's continue up to this roof now, we have a few floors to climb" She told him.

Thorax inclined his head.

"I'll take the point", He stated calmly motioning over to the wooden blue painted front door of the apartment.

"I've got your back" Twilight told him firmly as she followed him to the door.

Thorax stopped in front of the door, raised his glowing horn, drew back the heel of his boot and brought it right into the door beside the handle.

The door burst wide open under the sudden force and Thorax rushed out the apartment, aiming down the left side of the long hallway. Twilight rushed around to the right side, stood back to back with him and aimed her glowing horn down the opposite side of the hall.

Hungry inpony moans rang through the air on both sides of the hall, Thorax targeted the zombie nearest to him, a former middle aged stallion, and blew his brains out with a single shot of his magic. Next he targeted the former stallion and mare behind the collapsed zombie.

Twilight leveled her horn at a zombie crawling on the ground towards her and shot it with her magic and made its head blow and it nearly made her throw up.

When Thorax turned around she saw Twilight with a green face probably because of the zombie she killed so he walked up to her and covered her eyes with his gloved hoof.

Twilight gasped and blushed when she noticed that he covered her eyes with his gloved hoof then he lead her away from the zombie she had killed then he removed his hoof from her face and said "Feeling better princess Sparkle ?"

"Yes thank you"

Then a zombie was walking towards Thorax and was about to scratch his mask so he ducked the attack and grabbed his head, then he gave the head a quick jerk upwards and to the right snapping it's neck cleanly.

"My favourite attack" Thorax said to himself.

"Whoa a neck breaker move ?" Twilight asked him crouching and examining the dead zombie "you should teach me that move... but preferably not on me"

"Maybe"

Then there was a creaking noise above them and they quickly looked up.

"What in Equestria was that ?", Twilight asked Thorax.

"A Licker ? Another bioweapon ?" Thorax suggested calmly.

Then the rooftop shook with incredible force, then a silent cold dear gripped Twilight by the heart suddenly.

“Oh no please don't be what I think it is” said Twilight in her mind scared.

Thorax was about to say something, when the ceiling burst open a large hole revealing the night sky above. Something dark and heavy dropped through the hole and onto the hardwood floor in front of them, Twilight looked away from the large cloud shielding her eyes from the dust.

The dust around the figure slowly settled.

Twilight lowered her hoof as her vision cleared and she turned back to the gigantic crouched figure in front of them, which Thorax was already starring at, his gas mask emotionless.

Twilight's heart pounded rapidly in her chest as she took in the creatures full appearance.

“It's even more hideous up close” She thought fighting back a wave of revulsion.

It stood fully upright. It had hooves of a changeling, it's face was brown, it's coat was armoured black and had glowing eye and it held a giant bow gun.

It let out a deep growl, raised it's hoof and pointed at Twilight.

"PRINCESSSSSSS!" The Nemesis growled at her.

"Uh oh" Twilight said to herself quietly.
