Deadpool did it. Equestria was saved. It had been a long time, and the final battle wasn't easy, but with his friends, all from different dimensions and versions of Equestria themselves, the world was, though destroyed, was now saved. After drinking hard, somehow with his costume still on, and passing out, all of his friends left him alone in his house, each taking a piece of an infinity stone with them, probably the only smart thing Deadpool did to make sure Equestria would be safe once again. Then, the door opened. In came in was Princess Luna, one of the rulers of Equestria. Many of the ponies, including Deadpool himself, found her to be the most beautiful thing to live: she was surrounded with dark blue fur, her mane & tail both flowed while looking like the night sky itself, and, despite being over 1000 years old, excluding her time banished on the moon, she looked young. Next to Luna was nurse Redheart; a white earth pony mare with a pink mane that was one of local nurses of Ponyville, the place where Deadpool lived. Both navigated the landmine of filth to a snoring Deadpool.

"Deadpool?" Luna spoke. She poked him. "Deadpool. Wake up."

"...In a while, mom." Deadpool snored

"Deadpool! Wake up!"

"...Five... more minutes."

"...Deadpool! You're getting a sequel!" Deadpool snorted awake.

"A sequel!? Where!? I want one! I want it now!"

"Deadpool. Focus on me!" He turned to Luna.

"Oh! 'Sup Mooncheeks? Here to give me my reward for saving you?" He leaned down and rested. "I'm ready when you are."

"Deadpool, this is serious."

"What? I'll clean this place up, but, other than that, you're not happy that I saved the world from that jackass trying to destroy you all? ...Okay, so he kinda won... but my friends and I kicked his ass! And with all the feels I got, with that powerful magic I had surging through me, I knew you all had to live! Even the ones we may dislike."

"Yes... you told me that, already. But, Deadpool, do you see anything wrong with me?" Deadpool examined her.

"Hm... everything's where it should be... oh! Luna! What have you been eating!?" True to his word, Luna's belly was slightly bloated. "I know I say that your cheeks should be bigger, but not like this! Alright, tomorrow, we're both going to-"

"Deadpool... I'm pregnant." Deadpool stared quietly.

"Oh... well... congratulations! Who's the daddy!?"

"You."

"...Me?"

"Yes. You're the father, Wade." Deadpool blinked, but snickered, then laughed.

"HAHAHAHAHA!!! GOOD ONE!!! I take back on everything you said on being serious, that's HILARIOUS!!!"

"DEADPOOL!!! This is serious! You're the father!"

"Pfft! Yeah right! I'm sterile, remember?"

"...Nurse?" Redheart stood next to Luna and held up an xray to Deadpool. He took the picture and examined it.

"As you can see," Redheart pointed out. "the head is definitely that of a pony, but the body... it's that of... well... a human, as yourself, Mr. Wilson."

"Oh please!" He replied "Anyone can do this! I mean, it's not like-" Luna grunted to herself in pain. "Uh... what's wrong?"

"Nothing..." Luna replied, then glared to him "except that the baby is acting up!"

"That's not my kid! I'm telling ya! Discord!" The lord of Chaos, Discord, appeared next to Deadpool. With a snap, Luna was laying on one of her sides as Discord pulled out an X-Ray.

"Hm... let's see here." He examined, but his face went blank. He turned to Deadpool. "Is is yours."

"WHAT!?!?!?" Deadpool looked through the X-ray. He saw it; the head of a foal, but the body of a human baby. Deadpool's face went pale. "...Oh f**k me." He looked to Luna. "So... Guess we're going to change a couple of things around the house?"

"Castle." She corrected.

"What!? But-!?"

"But nothing! As much as it pains me, but... Deadpool... I know that we weren't happy with each other."

"'We?'"

"Fine... I wasn't happy with you, but... Please... We have to love this child together. Deadpool... Can you control yourself?" Deadpool blinked, but let out a sigh of defeat.

"You know... I was thinking of giving up my crazy ways of life. Perhaps meet a therapist, adopt a foal myself, possibly a Thestral, but... I was planning this a long time, ever since I saw your redesign in season 2." He pulled out a wedding ring. "Princess Luna? Will you marry me!?" Everyone gasped. Luna stared.

"D-Deadpool... You... You wanted to marry me!?"

"Of course!"

"Oh... Wade! I do! Come here!"

"Woo hoo!!!" Deadpool leaned in, took his mask off, grabbed the back of Luna's head, and they kissed each other passionately. It ended quickly as the nurse and draconequis gagged at the sight, and Luna wincing. "Oh God! I'm so sorry!"

"It's... Okay. Ugh... I've never had a child before. Is it this painful?"

"It is, your majesty." the nurse spoke. "You're going to experience many changes. Weight is one, but you're going to receive many cravings, and... Other things."

"Oh. Deadpool? Can you-?"

"Of course." Deadpool replied. He carefully picked up the Princess, straining himself from her weight, and teleported away. They arrived to Luna's chambers, where he set her onto her bed. "Oof! You are much heavier with that baby! Oh man, I hope it's not like me!"

"I hope so too. Don't want another you running around the house." Deadpool stared. "What is it?"

"Oh God... I'm the father of a Mary Sue."

"A Mary what?"

"A MARY SUE!!! AAAAUHHH!!!" He ran out of the room and around the castle. Many of the staff members just blinked and stared at Deadpool's behavior, but shrugged; he's practically a member here. Some of the guards approached to Luna.

"...Strange.... Now I want tacos."

"T-Tacos, your majesty?" One of the guards asked

"Yes. And perhaps some... Chimichangas."

"...Something tells me that this kid is REALLY going to be like Mr. Wilson." Another guard commented.

"Please, I think that this is just a faze. Hopefully, the child will be like me."
