It begins with Gilda bullying Pinkie Pie, calling her obscene and terrible names! But Wade is there for the rescue, out of nowhere a bullet hits Gilda, Pinkie is surprised, Deadpool comes and is about to finish the job, but Pinkie told him not to. Deadpool and Pinkie shake hands/hooves they proceed to happily trot forward.
"Hey, by the way, I've never seen you without your mask before! I wanna see your face!" Pinkie said as she goes toward Deadpool.
"I wouldn't-" He said as she took of his mask, her face is terrified as she puts it back on. They go past the mutilated Gilda and they pass Lyra and Bonbon, Deadpool smacks Lyra right on the behind and she is surprised and kicks Deadpool.
"Why?" Asked the pink pony, she was very puzzled.
"I wanted dat pony butt." Said Deadpool.
"Hmm, oki doki loki" Said Pinkie Pie.
"Hey, Pinkie want to see the team I'm apart of?!" Asked Deadpool.
"You mean the X-Men?" Asked Pinkie.
"Yes, there's Baldy, Wolvy, Cyclops, or Gazerbeam from the Incredibles." Said Deadpool.
"Sure!" said Pinkie, they go to the X-Mansion, an unamused Wolverine comes along with a very kind and welcoming Professer X.
"...Hi Wade, Pinkie." Said Wolverine
"Welcome, Deadpool, and you, I don't think I've seen you before, little pony, who are you?" Asked Professer Xavier
"My name is Pinkie Pie, D-Pooly's sidekick!" Said Pinkie
"Oh for god's sake, he showed you his 'D-Pooley' crap? (sigh) Wade, you won't get girls when you look like Freddy Krueger and Jason Voorhees had a baby." Said Wolverine
"Hey, Wolverine, he may look like that, but his personality is awesome, we both like cherrychangas!" Said Pinkie.
"What the hell is a cherry changa?" Asked Wolverine.
"Wolvy, Wolvy, it's a chimichanga, but 2 times better, think a chimichanga, but with CHERRIES!!!" Said Deadpool
"If you call me Wolvy again, I'm going to turn you into cupcakes, and Pinkie will help" Said Wolverine.
"Wrong fanfiction!" Said Deadpool.
"Yeah, please don't remind me of 'Cupcakes' I had to get therapy from that!" Said Pinkie
"Anyway, I'll show Pinkie Pie around the mansion." Said Professer X, showing her around the mansion, after a while she asks to join.
"Join the X-Men? Are you even a mutant?" Asked Professer X.
"Uhhh-" Said Pinkie
"YES, SHE USED TO BE A NORMAL GIRL BUT SHE TURNED INTO A HORSE, %100 mutant!!!!!!" Yelled Deadpool.
"Ok, ok, ok, yes you may" Said Professer X.
"YAAAY!!!" Said Pinkie and Deadpool.
"Pinkie Pie, your first mission will be against The Juggernaut, with Deadpool, Wolverine and Quicksilver." Said Professer X.
"Oki Doki Loki!" Said Pinkie.
Pinkie, Deadpool and Wolverine find Quicksilver, he's hanging out with Rainbow Dash, Wanda and Vision.
"Hey Pinkie Pie, I'm hanging out with my new best friend! Plus his sister and her husband." Said Rainbow Dash.
"Great, more ponies." said Wolverine.
"Oh, do you have a mission, can I bring Rainbow Dash?" Said Quicksilver.
"Sure! Let's go, we need to defeat Juggernaut!" Said Deadpool, as he and Pinkie trot and they go
The Juggernaut roars and runs into Wolverine, he gets his claws out, Deadpool gets his swords out, Pinkie and Rainbow Dash get into a fighting stance, and Quicksilver starts running in place. Rainbow Dash and Quicksilver run around Juggernaut, making him dizzy, Deadpool passes a gun to Pinkie Pie, and they shoot at Juggernaut, Wolverine takes the helmet off.
"Call Xavier!" Called Wolverine, Deadpool does so, Professer X comes and takes his mind, Rainbow Dash grabs him and sonic rain booms him, Juggernaut is knocked out, everyone is celebrating at the X-Mansion, Pinkie officially joins the X-Men, Rainbow Dash however declines, she'd prefer to be in The Avengers.
