Doomsday: Equestria

You'd think that he would bring an  army or something with him, but nopony was with him!  Just fucking walked into Canterlot!  Nopony really recognised him with all of the red and black scars across his green body and covering his cutie mark.  When he walked up to the Royal Gate to Celestia's castle, he was stopped by a dozen guards with weapons.  Shining Armor emerged.  He examined the pony closely, and then he pulled out a picture of Zyklon he had to keep on him at all times.  He looked at the green, red, and black pony, and then the picture several times over.  The only main difference was that he didn't have his horn or his dragon wings.  They weren't cut off, they looked like they've never even existed.  "Are you going to let me pass or what?"  The king asked in a proper and polite voice.  Shining Armor recognized that voice.  Immediately, he ordered the guards to surround him.

"I would advise against that, my dear friend.  I'll give you one warning before I have to do something you're gonna regret."  The green pony said politely once again.  The guards pointed their weapons at him.  Shining walked down to the courtyard where Zyklon was standing.  The circle of guards allowed him to pass through.  He came face to face with the bastard who tried to destroy the world.  Shining backhooved him sending him flying twenty feet in the other direction, causing him to leave the circle of guards.  Shining stood over the green pony with his face busted open.  "Shouldn't have done that."  The injured pony said politely once again before he let out a loud whistle.

There was a loud running noise that shook the ground as Shining and the other guards tried to keep their balance.  Around a corner, Shining spotted a very extremely massive gray figure appearing.  It was slightly shorter than Celestia, but it was the most massive being he had ever seen.  It made Iron Will and Snowflake look like complete pussies.  It had no tail and no mane.  In fact, the only pony thing he could see through the armor was a sapphire blue eye and a his white cheeks.  He just froze up as the massive creature sprinted towards him.  It ran up to him and head-butted him, sending him flying through the dozen guards, through the castle, through one of the guard towers, through the other gate of the castle, and into a random home in Canterlot.

"Good my friend, good."  Zyklon said to his enormous "friend."  "Now, we have to attach these collars to every unicorn we find.  Especially the royal ones.  Once the collars are on, push *this* button and it'll drain the energy from their horn into the canister on your hip.  Once we get the energy from the four princesses, then I'm going to put *this* collar on and you'll need to push the big green button and it should transfer the energy from the canister into the collar and restore my powers."  The King said as he put the collars around the dead unicorns that were killed by the huge...stallion?  Once all of the collars were on, the cyborg pushed the buttons on the collars and the energy was transported into the canister.  Zyklon licked his lips as he watched the magic flow into the canister on the cyborg's side.
