Sark’dan chuckled as he heard the small aliens talk, trying to intimidate him. They should have known better. Never challenge something you can not take, and this was a necron. The worst thing you could find. Yet these small beings challenged him.

« Arrogant fools !! » He laughed. « I will make you regret that decision forever. !!! »

He activated the small box and next he was a skorphek destroyer. He charged the guards, who were too surprised to do anything, and he swung his blade at the terrified ponies. At the last minute, he phased out. He then reappeared in another room of the castle.

« Why did I spare them ?? » He thought. « They are all lesser beings after all. »

He waltzed out of the room, tearing the wall in the process. He started walking over the small alleyways, carelessly crushing whatever furniture was in his way. He then made his way out in the open. He saw small aliens similar to those before. They watched in awe as he stepped down into the street. Some screamed in terror about a monster coming out of a certain twillight’s castle.

Sark’dan made his way to a field where some trees were planted and large red fruits hang on top of the tree. He walked slowly past a house. He walked slowly towards the forest. He had no idea where to go ... He opened a portal. Destination : two days later.

Sark’dan exited the portal. He made his way back in town. Suddenly, six small aliens arrived.

« Look. It’s that freak discord again!! » Said the blue one.

« I have no idea what you are t—- » he started

A beam of rainbow energy shot at him as the alien’s eyes glowed with power. He simply absorbed the energy, assimilating it as his own.

Soon, all six dropped from exhaustion. He walked towards them and he started talking.

* alternate universe twillight’s point of view *

My friends and I were looking for where discord could be when we saw that weird walking piece of metal, and we assumed it was a trick of Discord. We then proceeded to use the elements of harmony on him. At first, it seemed to work but then something drained us of our magic. I fell from exhaustion when I felt something pulling me into the air. I was face to face with a metal skeleton who looked at me with soulless eyes.

"You were too overconfident, young one." he started. " Maybe you could help me in a way......"

I felt psychic chains around me as I was forced to follow him.........

Hopefully somepony would arrive and help me. I tried to cast a spell but something constantly stopped me to do anything.

As if my prayers were answered I saw celestia coming in view.

* sark'dan's point of view.*

I saw a white alien walk towards me. It was sligtly larger then the others and had a rainbow mane and a rainbow tail. It looked angry but I didn’t care.

"You are to late discord, " it started. " I will definitively turn you into stone !!!!! ".

She didn’t look nice, so I simply flung a portal at where she was. She then entered the hell-hole known as « Catachan » and where she would most certainly find the infamous « toxic fart toad ».

I chuckled at all the possibilities when a full army appeared at the edge of my scanner zone.

« Hohoho »I laughed. « Let’s have fun!!!! »

I left the little captive near my back as I sprinted towards the army who started shooting small wood things at me. I fired a psychic blast to the left, melting some ponies and reducing the rest to ash.
I charged them and used my gauss reaper blades to cut through the ponies in front of me while my legs simultaneously impaled those still alive.I cut through their Armor as it was butter and I mercilessly slaughtered their soldiers.
My gauss heavy guns disintegrated the ponies and caused havoc in their ranks. Soon I spotted a white one with purple armor that was yelling orders and I assumed it was the leader. I charged in his direction, leaving nothing but death and destruction in my path.

*alternate universe shining armor’s point of view *

I was busy organizing my troops to attack discord when something sprinted in our direction. Some metal behemoth was charging them and the arrows seemed to do nothing. However, I was confident about my soon-to-be victory as there were five hundred ponies and one attacker.

He underestimated it.

I was stunned when I learned it was cutting its way through their rank and was killing all our guardsponies. I yelled for them to regroup but it was already in front of me. It was enormous. Three metal legs, two large green blades, a hand gripped over a staff and a hand magically holding.... Twily?

That monster had kidnapped his sister!! He would teach him a good lesson.

I was about to fire a magical blast that would annihilate him when I felt the ground changing and moving under me.
I fell into a sort of portal into another place.

« I hope you enjoy krieg !!! » Was the last thing I heard.

*Meanwhile in catachan.*

Celestia exited the portal, dazed but fine. She slowly walked in the dense vegetation when she saw..... A toad??? Not just any toad, it was the cutest she ever saw! She booped it's nose. Nothing happened. Then it farted, choking her to death.

*Meanwhile in krieg.*

Shining Armor woke up inside a city ruin. He tried to get up. He started walking, admiring the once proud city. It was about seven Times the size of manhetan. He saw bipedal beings with box weapons getting near him. He charged his Horn for an attack but a dozen masked dudes lasered him to death.

New update.
