Undead Raiser

Having discovered who was the responsible of this cataclysm and the ones who had murdered him, Brutus began his own quest to avenge every single horrible deed that had been done to him, Saving Equestria from this zombie apocalypse counts very little for him, if not nothing. Accompanied by the mysterious unicorn named Requiem, Brutus wandered across the land, mowing down every zombie who stands in his way.

However, as he proceeds in its mission, he began to subjugate most of the zombies with his unholy mark and began to form an almost imposing army under his will. That are Lessers, Flailers or Undementias, it didn't mattered to him. Every monster was welcome under his wing.

Their target was a cabal named the Reverse Tree, a cult that takes the mundus operandi of Fatima's holy tree, only different. As the days passes, Brutus's army grew more larger and dangerous, dangerous as his own determination to exact his revenge in the most brutal way possible. The keyword for that was bloodlust.

They had arrived into a very wrecked Ponyville, where most of the ponies fell under the assault of the zombies and the buildings were mostly destroyed. Brutus was quite surprised to notice that the Castle of Friendship was the only thing that remained almost untouched. Not that he can say the same thing for the other houses.

In the middle of this chaos, both zombies and victims were flailed by a undementia zombie with spikes protruding from his back and very long metal claws, someone who used to be Filthy Rich. Spoiled Rich, the mare nearby a pile of corpses was his first meal. And Diamond Tiara witnessed what had become of her father with horror. Filthy suddenly turned to her daughter with a comprehensive and yet crazed expression.

"Look, neither I wanted this," Filthy said. "But now it's the survival of the fittest the only thing that counts."

"P-please. Stop!" Tiara pleaded.

"I am sorry, but you will meet your mother," Filthy said crudely.

"Actually... I have another thing you," Brutus butted in.

Filthy didn't had time to turn toward Brutus that the later had it's hoof turned into a sword and split the zombie of Filthy in two, much to Tiara's shock. Just scene lured the attention of the other zombies, who started to rush toward Brutus, who nonchalantly turned it's sword into a hoof and pointed it at them.

"Slay them," Brutus ordered, causing a group of it's marked zombies to assault the markless zombies. It was a very discrete bloodshed, with organs and bodies being shredded. With a few sacrifices, the marked ones prevailed.

Tiara didn't know what to say. She could only react with shocked horror upon witnessing that. Brutus noticed her still shocked expression and put the things really clear.

"I didn't had done that for you," Brutus said crudely. "Now better run before incoming to the next boogie man."

Tiara followed suit, retreating to a destroyed building that used to be her house and hide inside, trembling in fear. Brutus nonchalantly turned away and returned his attention to his undead army gathering around him. Requiem tranquilly approached him with a smirk of glee in his face.

"That was a good a display of your power," Requiem commented.

"Shut up. I had just began," Brutus retorted.

"Oh... It's Walken that had spoke right now?"

"It's Brutus."

"Whatever, but pay attention to what is coming next."

"What?"

A scream briefly pierced the air. Brutus turned toward its source, only to see another undementia. A half draconic creature with three drill-like horns, iron tentacles for tails and side maws. That creature was none other than Mayor Mare. She was feasting on a agonizing cloaked figure.

"I lost my city and my dignity, but I can always enjoy life in another way, eheheheheheheh!" Mayor reveled.

"Damn you!" Another cloaked figure said, arriving on the scene armed with a curved knife.

"Stupid thug, I told him to not be this careless." A third one said.

Brutus had a glimpse of realization. "I recognize these bastards."

"They were the ones who had murdered you," Requiem said. "Now, it's time go all out in your fury,"

Without thinking twice, Brutus turned his clawed hand into a barrel gun and took a few step toward Mayor Mare, pointing it toward her. For the inahabitants of Ponyville, the zombified Mayor Mare was good pony, a diligent figure and a fallen friend of his. But for Brutus, she was just another monster standing in it's way. A very pathetic one for his standards.

"Hey!" Brutus shouted.

Mayor Mare turned her head toward him. "What do you wan-"

*BOOM!*

The bullet goes straight to Mayor Mare's skull, making it explode and leading her body to flop lifeless. The cloaked victim she was feasting on was dead after a few seconds of agony. The other two cloaked ponies turned toward Brutus and flinched in terror upon recognizing who he is.

"What the hell!? You again!?" One of them exclaimed. "But we had already killed you!?"

"And this form of his..." The other one said. "How did he got this power!?"

At that point, the other four of them arrived in place. "Who cares! Let's make sure that this time he will remain dead for good."

"Not today." Brutus threatened as he pointed its cannon at them. "TEAR THEM APART BUT LET ME AT LEAST ON OF THEM ALIVE FOR ME!!"

The marked zombies already rushed toward the cloaked ponies, numerous as they are. Most of the cloaked figures meet their ends. Two of them were devoured and mutilated without having the possibility to defend themselves and the the other five of them were battered and massacred by three unicorn Flailers through their magics and then their fangs.

As for the last one, he didn't run away. He has the guts to rush against Brutus with his curved knife. Brutus intentionally dodged the blows to both scoff him and turn his barrel gun into a sword. As the cloaked pony attacked again, Brutus finally impaled him with his sword and slammed his body against the ground.

Having consumed the massacre, Brutus exulted and reveled in what he did. The other normal ponies who were hiding, and Tiara, were very scared for what happened. Brutus didn't cared at all and enjoyed this moment.

"This nightmare is not over but at least I had my revenge with style." Brutus commented.

"Keep in mind, they are the tools of your death. Not the cause." Requiem reminded.

"I know that... So, what's next?"

"Since we have to find one of the Elements of Harmony, we have to go to Cloundsdale. There we'll have the chance to find Rainbow Dash."

"Aspirant Wonderbolts."

"But it's not as we are now that we'll get access to the town."

"But then how?"

"We are going to enter inside... as refugees."
