Slade took enjoyment in the look of disgust that crossed Celestia's face as he walked into her throne room, knowing full well that she wouldn't try anything to dare endanger her sister. Said sister was sitting on the throne that was slightly lower than Celestia's and she wore the same look of anger and rage that her sister wore, except that Luna's face had far more traces of fear in it. Deathstroke assumed that was because his finger was around the button that would tell the nanites to kill her. Which he was considering greatly.

"Celestia, it has been nearly a week since I saved your apprentices dragon and Cadence's daughter from the fanatics, hasn't it?" Deathstroke asked as he casually looked around, making sure that Celestia saw the trigger and that his finger was upon it.

"Yes it has. And during that time you have spent a considerable amount of time with Pinkie, much to Deadpool's dismay. He would come into my place at least twice a day and whine to me about missing his friend," Celestia replied in a calm voice, before her demeanor broke and a snarl spread across her face. "Cut the shit, Slade. What are you actually here for? The only time you bother to talk to me is when you want something."

"I see that you are learning Celestia. If I wasn't going to eventually kill you I would say that there is hope for you," Slade replied, the malice in his voice catching the sisters off guard. "I do not mean that I am here to kill you now, but perhaps one day. Of course, I will kill your sister and then Flurry if you do not answer my next question to my liking. Where is the heart of all magic in the world?"

Celestia's eyes shrunk down while filling with fear, telling Deathstroke that she knew exactly what he was talking about. He could also tell that her brain was firing on all cylinders as she tried to think of a lie that would buy her time. Slade's response to her attempt to think of a lie was to finger the button that would kill her sister, shaking her head slightly as he did so. Celestia looked from the weapon to her sister, wondering if she should betray her nation or her only living flesh and blood. Family won out.

"On a mountain. A mountain in the center of Equestria. Guarded by a barrier that can only be opened by alicorn blood," Celestia admitted through gritted teeth. "Inside you shall find a massive sphere of rainbow magic, the core of which supplies the magic of every magical being in the land. As well as the land itself. If you take the sphere-"

"Then every magical being in this land might die," Slade finished for her. "Oh well, loses were to be expected on this job."

"You...you are seriously going to kill every being on this world, and then the world itself, simply because you were hired to take the sphere?" Luna asked, unable to fathom how Deathstroke could say such a thin with such a neutral voice.

"I always fulfill my contracts, Luna. No matter what I must do to ensure my success," Deathstroke said with a smirk, one that went unseen by Celestia and Luna. "And I know that right now both of you are considering stopping me, so I will say this to the both of you. If you do try to stop me, I will kill Flurry Heart first. But if you let me go and take the sphere, I will bring her with me to my world, so that she will survive. It is your choice, princesses. Try to stop me and watch a filly die a painful death, before the rest of your nation follows suit. Or let me go and ensure the survival of one pony. You have ten seconds to decide."

It was an impossible choice. Celestia and Luna both knew that they couldn't let Deathstroke take the sphere of magic, as it would bring the death and destruction of their entire world. But they also knew that they couldn't defeat him quickly enough to stop him from killing Flurry Hearth. If they could beat him at all. But if they stood aside and let Deathstroke go, he would doom their world for certain. And they only had the world of a maniac that was planning on destroying their entire world that he would spare Flurry. Neither could decide which option was worse.

Then the doors to their throne room was opened once more and the Ambassadors of Harmony, along with Cadence, Shining and Flurry Heart, all walked into the room. For a brief moment Celestia, Luna and even Deathstroke were too stunned to speak. Then Celestia, taking control of the situation, cleared her throat and smiled as best she could at the new arrivals.

"Friends. You have all come at a rather...bad time. Whatever is troubling you I am sure that it can wait a little while longer, as I have to finish my talk with Slade," Celestia said as calmly as she could, watching Slade thumb the trigger and tilt his head towards Flurry Heart, telling her what would happen.

"But that's just it, Celestia. We came to help you," Twilight said, getting both Celestia and Slade to look at her like she was crazy. "All of us received a letter from you saying that you were in grave danger and that you needed us to assemble in your throne room at once. We grouped together and then we came here to help."

"But I never sent any letter. And who else would possibly-oh shit."

"Surprise!"

The ponies all screamed as a red and black clad mercenary burst through one of the windows, the most expensive and with the most beautiful image carved into it, and rolled across the floor until he came to a halt in the center of the room, right between where the ambassadors were and where the princesses and Slade were standing.

"There is no need to fear anymore my friends, I, Deadpool, sex master extraordinaire, am here to save you all!" Deadpool exclaimed as he placed his arms on his hips and stood in the beam of light that was shining in through the window he had broken. "I have learned of the evil that plagues you and I am here to stop it. I sent the letter to all of you so that you can all help me in bringing down-"

"ENOUGH!" Celestia roared with such fury that she shook the entire castle, shutting Wade up and turning all eyes towards her. "Twilight, please take you and your friends and leave this place. I need to speak with Slade alone and I do not want any of you here to bother us. As for YOU!" she snarled as she turned to Deadpool, who slowly pointed a finger to himself. "I have all but had it with you. Get out of my castle, get out of my nation, before you make this situation a thousands times worse than it already is. I don't know how you would do that, but I'm certain you will find a way."

"But, I-"

"Out. Now."

For a long moment Deadpool just looked at Celestia, pain clearly visible beneath his mask. Then he looked at each of the other ponies, each of who either glared at him or averted their eyes as he looked over them. All except for Pinkie, who shook her head slightly and motioned for him to continue. Then he rounded on Celestia once more, all of the pain replaced with rage.

"You know what, sun butt? Fuck you!" Deadpool roared at her. "I bust my ass since the moment I arrive here trying to get to know you guys, trying to help out and all you do is scorn my help and get mad at my attitude. I even decided to not go through with my contract to find and steal the source of all magic just because I liked you guys too much. But you, oh you and the stick you've got rammed so far up your ass that you can't even see it, just can't tolerate someone like me, can you? Someone who's truly different? Well, if you don't want my help, too bad."

Deadpool then whipped out one of his guns and fired right into the side of Luna's chest, getting her to cry out in pain as she collapsed to the ground. The ponies barely had any time to register what he had done before Deadpool aimed under his arm and fired another shot into the side of Flurry. The little princess cried out as she shook with pain, yet the filly had barley begun to cry before Cadence was hurling herself towards Deadpool with murder in her eyes.

"YOU FUCKING SON OF A-"

Deadpool chopped Cadence on the back of the neck and she fell to the ground, snarling in rage as she tried to move her body but found herself unable to do so.

"Give it a moment," Deadpool told them all, never taking his eyes off of Slade.

Just as Deadpool had said, a moment later Luna sat up, looking down at the spot where she had been shot to see a small syringe sticking out of her. The others examined Flurry and found the same syringe sticking out of her, one that had emptied an orange liquid into the both of them.

"Wade, what was that?" Pinkie asked Deadpool.

"That was to destroy the nanites in their bodies."

The room went deathly silent after Deadpool had spoken. Celestia and Luna looked at him with utter disbelief, unable to comprehend how he had known or how he had taken care of them. The other stared at the merc with confusion, but the looks on Celestia and Luna's faces told them that it was something serious he had just done. And then there was Slade, who gazed at Deadpool with an amused look beneath his mask.

"How did you figure it out?" he asked Wade.

"When the fanatic shot Luna, she bled a little on the floor. You were so gungho about getting Flurry back that you didn't notice, but I took a moment to take some of her blood and send it to Stark, asking him to examine it. And in exchange I would stay out of his series for a while," Deadpool explained with narrowed eyes. "He sent me an antidote and a way of detecting the nanites. But I already figured that they were in Luna from the way Celestia shoved her nose up your ass. If you had infected her she would have gone down with a fight. But if you had infected someone she loved..."

"Wade, what are nanites?" Pinkie asked.

"Little robots that Slade injected into Luna's and Flurry's blood stream so that he could kill them if Celestia didn't do what he said," Deadpool quickly exclaimed. All eyes snapped towards Slade as Wade said this, who calmly surveyed the room. Cadence shot back up to her feet, her magical aura blazing even greater than it had been.

"Is this true?" she asked in a whisper far more terrifying than the greatest hurricane or earthquake.

"Yes, it is. I needed leverage over all of you so that I could find the source of this world's magic without being hindered by you," Slade admitted in a way that made it sound like he was announcing the time of day. He saw the rage and hatred spread in all of their faces, but at that point he didn't care about them. The only one he kept his eye on, the only one that was remotely a threat to him, glared at him with narrowed eyes. "Yet why does this anger you? You are here for the same reasons I am. What do you care if I killed these animals?"

"Luna I don't give two shits about. I thought it was kind of funny you made bitch tits over there bend over backwards for you," Deadpool replied in a low voice. "But when I found out you did this to Flurry Heart, a baby, that you finally cemented yourself on my shit list. Also there was the fact that you shot me to save Spike, all so you could look good in their books. Hey dad? I'm going to kill you."

"I'm certain that you will try."

"You bastard," Celestia began, charging up her magic. "Now that my sister is free, I'll-"

A moment later blood splashed across Celestia, blood that came pouring out of Deapool who was suddenly in front of her. The sound of the gunshot that would have killed her followed a moment later as Wade fell to the floor, causing her eyes to widen as she realized that Wade had just saved her life.

"You'll what, Celestia? Had Wade not dove to shield you there, you would have died without ever knowing you were dead. That's how easy it would be to kill you all," Slade said with a wicked smile to Celestia, before holstering his pistol. "However, I have wasted enough time here. Wade, you are smarter than I gave you credit for. That's all the praise you will ever get out of me. As for the rest of you, enjoy your last days of life."

Deadpool pulled out his blades and lunged towards Deathstroke, yet the assassin pressed a button on the side of his suit and he vanished in a burst of light, leaving Deadpool to slash at the air where he had been a moment ago.

"Of course he's got a fucking teleporter. Mother fucker beat Batman," Deadpool growled to himself as he sheathed his weapons, turning around to see all of the ponies looking at him. "What the fuck do you all want?"

"Wade, Deathstroke his heading to the source of all magic in this world," Cadence told Deadpool, who rolled his eyes under his mask. "He is the most dangerous foe that we have ever faced and he plans to kill us all by taking our magic. If we hope to stand even a chance of stopping him, then we will all need to-"

"Let me stop your right fucking there. There is no "we". There is only you and him," Wade snapped back in a far angrier tone than any had heard him use. "You think after everything you've said and done to me that I'd help you fucking bunch of rainbow pukes? I stuck my neck out for you guys, tried to be your friends, and even destroyed the nanites that would have been used to kill Luna and Flurry. And how did you all respond? By calling me a freak, by trying to kill me and acting like everyone else. Acting like just because I'm a funny immortal guy that I'm not a person. Fuck you all."

"Wade-"

"No. Shut it. You're on your own. Good luck against one of the few guys in all of the multiverse that could probably kill me," Deadpool said as he pressed a button on his belt, causing his body to begin to glow. "Because when you fail to kill him, he's going to wipe out your entire world. I'd say it was nice knowing you, but that would make me a liar."

And then Deadpool vanished in a flash of light, leaving the ponies alone and very much afraid.
