This is my longest running story so far (A year and a half!), "Shanghai'd!"! While it is heavily inspired by One Piece, I still draw inspiration from other media as well. Regardless, most material in the fanfiction is quite original, and from the start I really wanted this to be a very unique and independent tale. Listen, I'm not going to waste your time giving you a five-hour explanation on the sub-plots and characters, so I'll just tell you the premise of it all.

Spike and Fluttershy end up on a privateer ship headed to another continent, Spike learns he's royalty, and so he embarks on a journey to not only find his true identity and purpose but save Equestria in the process.
