After saving the future from Paradox, Yusei prepares to return to his own time. But when the Crimson Dragon veers off course in the rift, Yusei finds himself in a strange new world... populated by brightly colored talking equines. Yusei meets Twilight Sparkle and her friends and becomes their friend as well, even teaching them how to duel. But something isn't sitting right with Yusei and he soon learns why he was brought here when an ancient enemy reappears and goes on a destructive rampage.

This is my first attempt at pony fanfiction, though not my first try at writing in general. I have no idea how this is gonna go, but be honest.

Regarding the duels: I intend to describe the actual gameplay just as much as the monsters and card animations. I'm not just a fan of the Yu-Gi-Oh! franchise, but a Duelist myself. As far as the rules go, I'll try to help the unfamiliar understand the game in the beginning. Card and player stats will also be displayed during the duel portions of the story (I'll try and write it so that they don't disrupt the flow of the story too much). But beyond the stats and character descriptions of their cards, you'll have to look stuff up yourself. You can do so on the Yu-Gi-Oh! Wiki.

Neo Domino City is a war zone. The mysterious Black King has spread his shadowy influence throughout the once-thriving metropolis. A small resistance movement is fighting against him, but they can't last much longer without help.

In Equestria, the balance is beginning to shift to the darkness. Twilight Sparkle and her friends are sent across dimensions to the human realm to discover the source of the imbalance and to repair it. But she'll discover much more than that, and will eventually learn the true connection between her universe and Yusei's.

A My Little Pony: Friendship is Magic x Yu-Gi-Oh! 5D's Crossover.

Twilight finds herself in another world after a direct conflict with some strange individuals, who are after the Elements of Harmony. In this other world, she meets up with a particularly special person and his friends, known as the Signers.

Given the circumstances, an alliance must be made to protect both worlds from the impending threat.

Note: Tags may be edited accordingly as the story progresses. Also, credit to Sapphire Jewel and a couple other friends (don't even know if they have accounts on this site) for aiding in some parts of the story.

Comments and critique are encouraged. Gore tag is due to some violence and blood present in some chapters.

Yu-Gi-Oh monsters are appearing Equestria, some friendly, others not so much. Nopony knows where they came from or how they got here, only that their wold has changed. Three of these monsters are running from death and makes unexpected allies/friends with the residents of Ponyville. Will they be found and be eradicated or will they survive and start a new life? It's all in the heart of the cards now. Rating may change through out the story.

What happens when ponies get sent to a yugioh playing Earth? Ask sophmore Eric Sullivan. He was dueling at school when the Mane 6 fall through a hole in the sky. But they were'nt the only ones, alot of extremly powerful cards and a dark enemy come with them.

This takes place about 10 years in a future where just about everyone loves to play yugioh.
Note to all cloppers and furries, it only goes as far as belly rubs and light kissing.

Edit: Am redoing duel formats.

The Mane 6 find themselves joining Duel Academy, after being taken to the human world. Twilight is trying to find a way back home, Rainbow is rivaling with Chazz, Applejack is worrying about the farm back home, Rarity is fawning over her Gemini deck, Pinkie is dueling everyone for fun, and Fluttershy is scared of dueling since she thinks the point of the game is to kill digital pets.
(Note: This series is supposed to start in the middle part of season one of GX (after the School Duel) and the end of season 4 of MLP.)

Welcome true believers and newcomers all alike!

You might not be able to believe what I’m about to say, but everyone’s imagination has the ability to open countless worlds to anypony’s mind. Sometimes these worlds are nothing more than blurs, other times we can see them as crystal clear as the blue sky above. When we see these worlds as clearly as we can, we take inspiration from what we see.

Creating inspiration!

Bringing hope of a new world!

But are these worlds real? Or are they just figments of our imagination?

There is but one way to find out… So let’s turn the page so we may see what fates await, what twists will turn, packed with chilling thrills, and of course heroics!

(Slight crossover from the Yugioh Card Game).

(Story takes place in an alternate Equestria, where Duel Monsters are all the rage. No canon characters will appear in the story, however when Episode Zero chapters have been completed, and the real story has begun, you, the viewers, may make a request for certain characters to be referenced at certain intervals in the story. You'll also have a chance to have your own OC's, should you have any, to appear as well, but this won't be in effect until AFTER Episode Zero has been written)

Duel Monsters.

It is a card game unlike any other. Through the use of magically imbued devices, these simple cards become something much more, as they are brought to life to do battle, under the command and orders of those who play the game, known as Duelists.

Of all the Duelists in the world, there is one whom many have sought to find and defeat, even dedicating their lives to such a cause. A supposedly ancient entity known only as the Ancient One, a powerful Duelist who is said to grant one wish to whoever should best him in a battle of the cards.

Many of those who set out to find him do so for the desire of wealth, fame, power, or immortality. For one young Duelist, it is for revenge, for the irreplaceable loss he suffered some years ago. Revenge for being deceived into believing a great lie that has costed the lives of many before himself.

Unique, armed with his father's mighty Deck, the only item he has to remember him by, sets out to face and defeat the one who caused him his pain.

However, unbeknownst to him, his journey, his mission, whether successful or not, will mark his first steps to becoming one of the greatest Duelists ever to rise up in the world.

It's time to Duel.
