This story is a sequel to Nigel M Chalmers, Emperor

(15/10/2015) Turned status back to incomplete pending an Epilouge and Alternate Endings chapter as per comment suggestions.

After being banished by Celestia for his misdeeds, the alien Emperor of the Crystal Empire is back... and out for revenge.

Emperor Chalmers is not a happy space man. After being stabbed in the back by Equestria, he was sent to the depths of the Underworld. Kicked out for causing too much trouble for the wardens, Nigel now has the chance to take back his empire and show Celestia just how disappointed he is with her.

This time things will be different. This time he has friends.

Benjamin is ready to face the world of Equestria, or so he thinks. Still oblivious to the cultural differences, he accidentally wins the hearts of two mares. Problem is, they aren’t keen on sharing the human. Can two ponies that are as different as the day is to the night be able to come to terms with one another before hearts end up broken?

Based on a true story. Kinda. Not really.
A man named Jason previously led a rather melancholy life before he died violently. No surprise there. But as he wakes up in Equestria and is thrown into a foreign body, he is forced to survive with the guise of a changeling. Taking place shortly after the failed changeling invasion of Canterlot, how can he keep from being revealed by new security measures, and blend into this new world, while making use of the most unlikely of allies? But of course, avoiding ponies only turns out to be the easy part when trouble has a habit of reading its ugly head. Really though, what could go wrong?

Props to the ever epic Zubafa for his cover art.
