Twilight Sparkle of the human world has created the first ever Artificial Intelligence program that can learn and further evolve. She has also uploaded that program into an already highly advanced robot, creating the perfect protector of peace.

There, he meets an inmate named Tirek who clearly seems to lack the ability to make logical decisions.

By popular demand(and by that I mean only one person voted, so thanks JD) here is the next story in my united stories! However, this is a prequel to what happens later in this universe.

A My Little Pony: Friendship is Magic/ Sonic the Hedgehog crossover

WARNING!!! Contains big spoilers from the Sonic the Hedgehog (2006) game, as well as a few comic references.

This story contains no crazy crossover shippings, (although strong friendships are formed,) and is my attempt at creating a decent MLP/ Sonic crossover that does well at presenting both universes both with accuracy and depth. I have also tried to keep this so that it is as close to canon as possible for both worlds, although I naturally elaborated on some things.

When Twilight Sparkle and her friends are sent to go to the strange world of Mobius to defeat an ancient evil, they end up encountering a strange, spiky blue creature named Sonic. The ponies easily make friends with Sonic, but soon find that not all of the people on Mobius are friendly. Mysterious events lead to misunderstandings, while an evil villain known as Dr. Eggman is setting his eyes on Equestria as his new target.
And amidst all of this lies a great mystery, a mystery that will shed some shocking revelations on how Equestria and Mobius share a great deal of history, on the origins of the being called Solaris, and on a dark threat that both worlds know all too well.

Other than the listed characters, you will get to see the Cutie Mark Crusaders and a good deal of background ponies share in the adventure, and a bit of Discord, as well as a great deal of short appearances by other .

Sunset Shimmer and Twilight Sparkle have a few drinks together... Okay, maybe more than a few. This is followed by a desire to do some science. This simultaneously goes much better and much worse than the girls would have expected.

Thanks to Novel Idea for the story prompt inspired by this great comic by Crydius.

My programming or my training did not prepare me for this. I understand completely what I must do to protect the people of my city, but when confronted with these...ponies, I am not sure how my directives work. But I do know that they live like people and feel like people, so I shall carry out my duties to them as if they were my people. And that is to serve their trust. Uphold the law.

Protect the innocent.

Robocop will be the older version and most of the story will be him from the first movie with some of the other two added in. Robocop will still be more machine than man when the story begins, so he won't talk that much or have too much inner monologue, but from there...we'll see.
