[X] Discord sends them onward via cake.
[X] Deadpool decides to make it his task to prevent any and all forms of angst in his presence. Via high explosives.
By the time Celestia's reply had returned, Pinky Pie's party was already underway.
Pinky had truly outdone herself this time. Balloons and cake and streamers and fireworks--
Whoops. Rewind.
And a red pony with black markings playing with high explosives.
"What's that do?" asked a colt.
"It blows stuff up," Deadpool told him. "In many chunks, usually. However, as this is a Party Of Super Super Extra Fun(TM) , it explodes angst, leaving sparkles of happiness in its place instead. Best I could come up with in this place. Apparently blowing things up for fun isn't an idea that occurs to people around here."
"You blow things up for fun? Coo-ool."
Much later, Ponyville would look back on this day as one of the harbingers of doom, seeing as how it introduced Fireblast to the world and started him on his career. "Life is a blast!" was his motto. However, that does not concern us here and now.
Here and now, Deadpool was rigging an explosion that would be perfectly harmless to anyone who was not experiencing massive amounts of angst. To those with small amounts, it would release their worries and make them slightly more happy. To those with massive amounts of angst..
...of course, there was no such pony in all of Ponyville, so the explosive was perfectly safe. It was, in fact, extra strong because this was a party and would make those suffering from small worries extra super special duper happy!
"Not seeing any sign of trouble there, nope," Deadpool said cheerily. "Questioning the narrative gets you chucked out of the story. And we can't have that."
Applejack and Rainbow Dash had gone after Loki and had no effect on him. However, when Rarity had joined them, Loki had seen sense and grudgingly returned to town. She had been pampering him for hours, getting him an appointment at the spa (he'd hid his identity under a mud mask) and even making him a special outfit just for the party.
The outfit Rarity had made him was amazing, Loki had to admit, admiring it in the mirror. It suited his usual style without him having told her what that style was and yet complemented the colors of his coat and mane. "My thanks," he told Rarity. "It is a marvelous gift."
Rarity blushed. "Why, thank you, Loki. I like to think I have some small talent with clothing."
"A large talent," Loki told her sincerely. "My appreciation for your time and trouble."
"It was no trouble at all. I enjoy working for such an appreciative client."
"I regret I cannot pay you--"
"Why, don't think anything of it. You're a guest and a stranger to Ponyville. It's the least I could do." Rarity was unable to keep her blush under control. Such a handsome stallion. Such sleek lines and unusual coloring.
Pinky popped in. "Good! There you are! I was looking all over for you! I looked in the library and Sweet Apple Acres and the schoolhouse and..."
"Why were you looking for him, Pinky?" Rarity asked politely, hoping that she wouldn't lose contact with the stallion.
"Because I'm having a party, of course!"
"Of course. Shall we?" Rarity asked Loki.
Loki contemplated his odds of getting out of this without magic and decided that, so long as he stuck with the relatively tolerable mare, it wouldn't be too terrible. "After you."
Pinky cheered, turned a cartwheel and then ushered them out of Rarity's shop and into the town square where an enormous cake was standing. "--and it's blue and red and green and gold and black because those are your colors. Your and Deadpool's. I think they look great together. And so so yummy! I've already had some and it was deeeelicious!"
Loki spotted the dragonequus Discord by the cake the same moment he spotted Deadpool standing by a pile of high explosives. He fled for the company of the other trickster.
"Oh, Loki! So nice to see you again."
"Is it always like this here?" Loki inquired. "So peaceful and quiet--"
"--and utterly, completely boring? Alas, yes. I've spent centuries pretending to be frozen while actually taking a nap, it's so dull. This latest crop of ponies is more interesting than the usual run of the mill 'back you evil demon' types, but they've still got a long way to go before they embrace the chaos inside themselves."
"Ah. You have my condolences then."
"It's fine," Discord dismissed. "You get used to it. And I have a free hand. No other trickster wants this dimension. Speaking of dimensions, I have a way to send you home if you like."
"You do? And what will I owe you for this favor?"
Discord cackled. "Oh, we understand each other so well, don't we? Don't worry, I'm doing it, as they say in your home dimension, for the lulz."
Loki considered this for a moment, then judged the dragonequus as sincere and nodded. "My thanks. When do you plan to do this?"
"Oh, at the most inconvenient moment, of course. "
"Of course," Loki said. He should have known. "I don't suppose you can return my powers, can you?"
"Not for any price you'd be willing to pay. I'm only offering to get you home so that I cut down on the potential competition here. Not enough chaos to go around, you see."
Loki did see. He turned away, instinctively seeking out the greatest source of mischief in the place and finding Deadpool bounding toward him.
"I've got everything set to explode any second now," the mercenary-turned-pony said brightly. "It's gonna be a big bang! I'm going to rock your universe."
"Deadpool--"
"Relax," Discord told him. "Enjoy the fun. Remember, this is Equestria. Completely boring. They wouldn't have let him play with something genuinely harmful, not around other ponies."
Loki's heart calmed down and he nodded. "Very well then. I--"
And then two things happened simultaneously. Deadpool's explosion went off and the cake blew up, covering Loki and Deadpool. As it settled over them, it dissolved them, leaving nothing behind but crumbs.
"Sweet delicious crumbs," cried Pinky Pie.
"I never said who it would be inconvenient for," Discord mused, even as Twilight Sparkle started for him, anger sending sparks through her horn. "And I would have traded you your powers for your cutiemark, but alas, even though you would be initially willing to make the trade, you would have resisted once you realized what I was really taking away from you. A pity."
Where and when does Discord send them in the Marvel verse?
What happens next?
