MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

QUICK WARNING: This fanfic was written by a 13-year old who has trouble writing essays for school. If this fic is absolutely horrible offer constructive criticism, not hate comments and dislikes.

On one of Luna's vacations, she comes across an almighty object: the Honto no akumu. This object reverts her back to Nightmare Moon, and aware of what will happen when the Elements unite, she kidnaps all of them. Only Rainbow Dash escapes. However, Nightmare Moon manages to see what happens and sends some of her now-corrupted lunar guards to shoot Rainbow down. Rainbow barely survives and crash-lands in the refugee-filled, unnamed hideaway. Fortunately, most of the village's residents are technological geniuses from Canterlot, and they have been forging new weapons to combat Nightmare Moon. After nursing Rainbow to health, they bless her with the most powerful weapons they created: The Hamoni no buki. The laser gun and barrier can alternate between firing and protecting against solar energy, and doing the same with Lunar energy. On a quest to save her friends from Nightmare's grasp, Rainbow must fight against solar and lunar guards from Los Pegasus to the now distopian Canterlot, and find out why everyone has been referring to things in foreign languages! Or maybe that's just her.

Crossover with Ikaruga. I do not own the characters from MLPFIM or anything from Ikaruga, save for a copy of the game myself.

(Now remains on my profile as a memorandum to how horrid I was at writing crossovers.)

When Wreck-it-Ralph finds a villain character who seems to have gone Turbo, he finds more than a handful in the handful sized sprite.
For one thing, she has no idea what game she comes from.
For another, her code seems completely foreign to the Arcade.
For a third...she's absolutely adorable.
Having only just finished cleaning up after King Candy's mess, this little Nightmare could be a problem...or the greatest blessing Ralph has ever received.
And shadows from the past move behind the scenes...

Sonic, Shadow, and Silver have been sent to the world of Canterlot High along with the seven Chaos Emeralds by the Master Emerald after hearing of a prophecy about the fate of worlds. They will have to go through school again if they are to regain the seven Chaos Emeralds and saved the worlds from the eternal darkness, for the emeralds have been claimed by some of the students of Canterlot High.

After a summoning mishap, six champions from Runeterra's League of Legends arrive in Equestria. At first, they are focused entirely on getting home, but soon find out that it might be more complicated than they thought when Discord decides that he can use them for his own ends. Continued in The Redemption of Jericho Swain

All Dante ever wanted to do was lay back, relax, and - eventually - open and run his devil hunting business. He certainly never wanted to get involved in anything regarding the fate of multiple worlds, power hungry demon lords, insane cultists, and certainly not parenthood.

But then he got a party invitation from his brother...and on the way to the party, he found a tiny orange pony, who proves despite physics to be far more than a handful.

Once, I was a simple human. I spent my days living my life and enjoying as the days slowly ticked past. I had a girlfriend who loved me and who I loved in return.

That all changed one day when I went to a costume party dressed up as the character Amaterasu from the game Okami.

Now I don't even know what I am anymore.

I have the powers of a god, but what am I supposed to use them for?

Edited and Proofread by Courage Fire and tytyvm starting from Fourth and Fifth Howl.

After an accident involving a Lightning Chariot joyride, Viridi, Goddess Of Nature, ends up in Equestria. She soon finds herself in a conflict with a newly revived Hades, Lord Of The Underworld who has his own plans for Equestria.

I don't own Kid Icarus, any of the characters from the series or out of the series.

Kid Icarus belongs to Nintendo and so do other Nintendo characters mentioned in the story.

Roxas and Naminé had resigned themselves to their fates, having merged with Sora and Kairi; their short lives had come to an end. What they didn't expect however, was to be drawn into a land of talking ponies. Now they must become its guardians as old enemies from their world's past threaten the future of this one.

Fate is up for grabs in a race against time as this new world around them starts becoming overwhelmed by darkness. Bonds of friendship and greater will be tested time and again as the two Nobodies try to find their place in this new world and keep it from being consumed.

The future is up for grabs, and it will be up to Roxas and Naminé to decide which will come to pass.

Dr. Albert Wily...mad genius, evil scientist, brilliant roboticist, wanted criminal, would be world conqueror, loving father... Wait, what was that last part?

When Dr. Wily wakes up one morning with a tiny unicorn inexplicably clinging to his bald head, he is more than a little flummoxed. Unknown to him, this tiny creature is about to turn his entire life upside down, worm her way into his heart...and make his dreams a reality.

Can you feel the Wub tonight? Mega Man sure will.
