Author's Note

If you ever wanted a MLP story based on the Marvel Zombies comics, here it is. I also suggest you go read Ultimate Fantastic Four #21 to #23 before reading this.

Crossover, Part 1

It was just a usual day for the Princess of Friendship. Piles of books scattered the room from where her research had taken priority over cleanliness. She was just beginning a book on the ancient history of Equestria for the sixteenth time when there a huge flash of light that momentarily blinded Twilight. As her slowly eyesight returned, she saw another Twilight in front of her. However, the new Twilight didn't seem like like she was actually there, rather she seemed to be some sort of hologram.

"Wait, will I mess with time travel again? You'd think that would have learned my lesson after what happened the last two times." The other Twilight soon smiled at Twilight.

"Ah, just the unicorn I was looking for." Upon closer inspection, the holographic Twilight came to a fairly shocking realisation, "Wait, are you an alicorn?"

Alicorn Twilight took a look at the holographic Twilight, and quickly noticed that she was a unicorn. "Okay, so not time travel, because I'd definitely remember if I saw myself as an alicorn when I was a unicorn."

"Ah, yes, let me introduce myself. I'm you, but from a alternate universe. I'm currently on a quest to recruit other versions of myself in order to defeat a villain that me and my friends were unable to defeat." The other Twilight said. Alicorn Twilight became almost ecstatic in an instant.

"Wow, I've been studying about the possibility of multiple universes, but to think it's actually true and an alternate version of me actually learned how to travel between them."

"Well, actually, I'm not in your universe. I'm still at mine. What you're seeing is just a projection of myself. And actually, you're the first other Twilight I've seen on my quest to recruit other me's and as such, the spell I'm using isn't perfected." The other Twilight explained.

"Oh, I see. You said earlier that you were unable to defeat a villain. If you don't mind, who is this villain?" Alicorn Twilight asked.

"I'll tell you the details later. For now, we have a more important matter at hand. I'm not sure how I could transport you to my universe and I was wondering if you would help me perfect the spell I'm using."

"But my schedules..."

"Please, Twilight, I need your help."

Alicorn Twilight sighed, mulling it over for a second before responding, "Alright then, I guess I can't refuse myself."

"Great! Now, here's a written version of the spell I'm using." The other Twilight levitated a scroll for Twilight to view.

"Hm... I don't completely understand the spell, but with some experiments, I should be able to perfect it. But it'll take time."

"That's fine. With the two of us, we should be able to get the spell perfected in a day or two!"

A few days later.
Rainbow Dash flew towards the hill next to Ponyville. Being Rainbow Dash, she didn't waste any moment and practiced flying while doing so. Soon, Rainbow Dash was at the hill, where she found her four friends. "Hey, guys! Sorry for being late, I was practicing my flying."

The four ponies were more than used to Rainbow being late but what they were more worried about, was Twilight. Nopony have seen her for the past few days and she didn't seem to have read the invitation letter they sent for the picnic they are having. "I don't know about all of ya, but Ah'm awfully worried for Twilight. Ah visited the castle before getting here, and Spike said that she has locked herself in her room, only coming out for food." Applejack said.

"AJ, relax. It's just typical Twi." Rainbow Dash proceeded to put on her shades. "Besides, if she has a problem, I'm sure she will come to us, like the last picnic we had. We just have to make sure we don't ignore her."

"I have to agree with Rainbow here, I mean, what could possibly go wr-" Rarity was stopped by Pinkie whose full body was vibrating.

"Pinkie Sense tingling! I can feel that there will be a doozy that will happen to Twilight!"

The others looked Pinkie with only a thought in mind: “oh, no.” The five ponies quickly raced towards the castle, with Rainbow Dash reaching there first. Being Rainbow Dash, she didn't let a door stop her, so she crashed through a window. "The door wasn't locked, y'know." Rainbow Dash heard Spike say, who had somehow already got a broom in hands. Rainbow Dash laughed awkwardly as the rest of the mane 6 arrived.

"Spike, where's Twilight?" Rainbow asked, Spike quickly pointed towards a door to the far left. "Thanks, Spike!"

"Wait, what happene-" Spike didn't get to finish his sentence as the ponies ran off. Spike sighed. "Well, cleaning glass shards it is."

Meanwhile, Twilight was just about ninety-nine percent done with the spell. "Y'know, this would have been so much quicker if got you someone else to help too."

"Well, I'm almost done anyway. I just a few more touches and.... Done!" The other Twilight seemed very, very happy.

"We can't waste any time. Quick, come over now. And take the scroll with you. My memory has been awful lately, so it's best that you bring that along." The other Twilight explained, almost as if she needed the scroll to live.

"Oh, okay then. Well, here goes nothing." Twilight's horn lit up and she started casting the spell.

"Twilight!" Twilight suddenly heard, before there was a few knocks on her door.

"Girls?" She stopped the spell and wanted to unlock the door but the other Twilight let out a scream. "What's wrong!?"

"I'm being attacked! Quick, I need your help!"

"I'm on my way!" Twilight quickly lit her horn up again and used the spell. In a few seconds, Twilight teleported away and the hologram was gone. The locked door was soon knocked down, with the mane 5 rushing in and searching frantically around for Twilight.

"She's gone!" Rarity shouted.

"I've got bad feeling about this." Rainbow Dash said.

When Twilight opened her eyes, she expected to see the Golden Oaks Library, just like the one the other Twilight have described. Instead, the library seemed to be in ruins, books where all over the place, and most of them were torn. "Twilight?" The alicorn said, hoping for a response.

Not hearing anything, Twilight went downstairs, and once again said, "Twilight?" No response. She checked the whole library, but the other Twilight was just not there and the whole library looked trashed. There was a rotting smell and the whole place just seemed moody. "Oh my Celestia. What happened? This is horrible." Not seeing any other choices, she headed out of the library, to find a Ponyville in utter destruction. Twilight took a few steps forwards, and found a skeleton in the distance.

Twilight was just about to scream, when she heard hoofsteps walking towards her. She saw six ponies' silhouette in the distance. When Twilight got a better look at the six ponies, she recognized them as her friends and herself, but there was bloodstains all around their coats, and their teeth were showing.

"Ever get the feeling you've been had?"
