A Fallout: New Vegas/My Little Pony: Friendship is Magic crossover

2022 REWRITE IN PROGRESS

After being rudely awoken from Cryo-sleep, John-117 finds that the Forward Unto Dawn has been sucked into a gravity well, causing it to fall towards an unknown planet. In the crash, he is separated from Cortana and falls alone into the Everfree forest. In addition to this new complication, old memories from a scarred and tragic past haunt his dreams, putting his remaining sanity on edge.

However, he has little time to ponder these thoughts, as he encounters the planet's... peculiar... inhabitants.

First 19 Chapters proofread by Bravo 539 and Shadownamesto.

Current rewrite will not necessarily follow the old story but certain events and details may be reused.

Deep in the confines of the Everfree Forest exists a secret research facility. Spreading false lies of the forest's dark nature and releasing dangerous creatures into the Everfree was necessary to prevent any accidental public discovery of the nature of the secret facility. Inside, scientists and wizards work side by side to amass weapons, both organic and inorganic, in case the Elements of Harmony fails to stop any threats that challenge Equestria.

But what happens when a creature, designed to be the perfect killing machine, turns on its creators?

Instead of being killed in the cold Antarctic by Dr. Manhattan, Rorschach finds himself rematerialized in a strange new, pony filled world. He finds himself drawn into the lives of the ponies of Ponyville but some ponies fear that this sociopath will bring danger and darkness to an otherwise peaceful existence. Will the mane 6 help Walter Kovac find peace within himself or will he bring them all down with him in his cold views of reality and existence?

"I'm Yah-Shee and he's Arrell, and it's our job to analyze their weapons, armour, and skills to find out who would win an Equestrian Death Battle."

This story takes the concept of Death Battle and carries it over into Equestria, pitting different ponies and other Equestrian creatures against each other in one-on-one fights to the death to see which is superior. Extensive research is done on both combatants to figure out who would win, and is presented as a written battle to be more entertaining.

Readers are asked to suggest possibilities for battles in the comments, or by messaging me. You are allowed to suggest OC characters, as long as they are from a story that is at least somewhat well-known.

"But for now, it's time for an Equestrian Death Battle!"

One clear beautiful night Twilight is stargazing, nothing uncommon there, but as she is about to pack away for the night, she spots a faint star that she has never seen before, and that none of her books mention, but on her quest to find out more about this star, she makes an unusual friend, and maybe even more than just a friend.

Little does she know that her new friend will lead her on a completely unexpected adventure as she learns more about him and about his past. As each question is answered new questions arise as Twilight is taken through twists and turns physically, mentally and emotionally, until eventually a massive secret that threatens to upturn everything she knows.
