The Pyro and The Engineer's Misadventures in Equestria

"MMH FHH FHH FHH FHH!!", Über Pyro laughed maniacly as he thrusted his Strange Phlogistinator upwards. He charged towards the five ponies while firing his Phlog. They narrowly dodged, and watched in terror as the giant, brainwashed Pyro melted a 100-foot crystal shard in less than 3 seconds. Pyro charged again, spewing the eletrical rays in front of him, obviously doing the W+M1 technique(Protip: Don't do it on TF2, it's hard). The five jumped out of the way again, almost being melted. Pyro crashed on a crystal wall, while the Phlogistinator kept burning uncontrollably the crystal. It was reduced to a pile of orange cinders in 1 second flat.

"We won't make it!", Twilight cried.

"Yes, you will.", an unexpected, but familiar voice called out. They(including Pyro) looked up to the gap, and to their surprise, found Engineer(with a robotic hand) and Applejack standing there in the middle of 40 Combat Mini-Sentry Guns. "That there's a pratical problem. An' ladies, I solve pratical problems.", Engineer continued. Lots of little 'beep's were heard s the Mini-Sentries pointed towards the giant Pyro. The two texans jumped out of the way as the Sentries proceeded to shoot Pyro.

Now, Combat Mini-Sentry Guns have a low knockback when alone. However, when they are joined with lots of other Mini-Sentries, they gain a monstrous knockback that beats even the high recoil of the Level 3 Sentry Gun. Pyro tried to cover the bullets with his left arm as he was inevitably pushed backwards. However, Pyro had a trick under his sleeve. The nozzle of the Phlog was crackling with red energy. If you played Team Fortress 2, you know that this means that the 'Mmmph' bar is full. Pyro chuckled evilly as he noticed it.

"Aw, hell. He's alterady charged. Plan B!", Engie said as Pyro thrusted his weapon upwards again, causing it to glow in a red color and a green circle to appear around him. "This is the plan: The Mini-Sentries will keep Pyro distracted. While he attempts to destroy them, you six will use the elements to stop him.", he quietly told the plan.

"But darling, we don't have the elements!", Rarity pointed out.

"We got 'em.", Applejack replied as she handed out the six elements.

"Where did ya found 'em?", Dash asked.

"No time, move!", Engineer answered. The six ponies wore their respective necklaces, and proceeded to connect their bonds together, as they levitated in the air. Meanwhile, Pyro finished destroying the last Mini-Sentry. He thrusted his Phlogistinator upwards to celebrate his victory. However, his cheering was cut short as he heard a strange noise. He turned around, and found a massive rainbow comming towards him.

*BOOM*

Pyro screamed as he felt like he was going to implode, but shortly after, he felt himself shrinking, and losing his memory. He didn't remembered much about what happened after. The first thing he saw was himself laying down on the crystal floor, next to a big crater shaped like his Strange Phlogistinator with the latter on the middle.

"Wfht hpfhnd?", Pyro mumbled.

"Discord somehow managed to brainwash you into following him, and made you huge. You made this mess here.", Engineer explained. Pyro looked around in shock.

"Tfht hlf-wfht WHFLL PFHY!!", Pyro yelled as he picked his futuristic Flamethrower and ran out of the cave. Engineer and the Elements followed him shortly after.

Meanwhile, on the capital of Canterlot...

During all the three weeks of the chaos age, all cities of Equestria were transformed into a chaos-induced place. Canterlot was not an exception. Even the Princesses were trapped into capsules made by the changeling queen. However, this day, Discord and Chrysalis had something planned in mind. The two warped to the almost-destroyed castle.

...

"Why, hello there, Royal Princesses!", Discord said outloud in a mockery tone. "Wow, you two are resting in changeling capsules? I didn't expected that. So 'underly' for the royal members.", he continued. He stopped when the bug pony elbowed him. "Oh, right. 'Woony', I have something for you!", he continued. Luna's ears perked up. She looked at the two, and gasped(or, atleast, tried to) upon seeing the jar with the starry liquid. She looked to her right, and found out that even Celestia was surprised. "Release it!", he commanded. Chrysalis opened the jar, and grinned evilly as the dark starry liquid flew out of the jar on it's own. It stood there idly, before finally moving towards the moon princess' jail. It spun around it, before covering it in dark power. It fell down along with the capsule, revealing the long-lost monster. Nightmare Moon.

"I thank you for releasing me from that blasted jar.", Nightmare spoke while grinning. "But at the same time, I'm angry at you for imprisoning me in there!", she continued, this time with an angrier tone.

"Whoa, calm down, 'princess'. If we hadn't trapped you in the jar, you could accidentally possess one of us.", the Chaos God replied.

"And wouldn't it be good?", Nightmare replied.

"Not really, we need the biggest ammount of members possible. The elements are teamed up with two mercenaries. The elements alone are alterady dangerous, and when teamed up with two professionals, they doubled their effectiveness.", Chrysalis responded.

"We don't have enough time for chit-chat. We have a place to take control of. Better: A whole PLANET to do it. We could have eternal night, break in total chaos, and take out the ponies' love, all at once!", Discord called out. The two nodded, and laughed maniacly.
