Solar Opposites pirate AU

Half of the population are aliens and the other half are humans. Yes this is going to be like Solar Opposites if it was Pirates of the Caribbean but that's because it's the only pirate story I have for reference. Terry x Korvo (obviously 😏)

Terry is a crewless pirating buckaneer. He and his rescued apprentice Jessie travel the seas trying to Robin Hood the shit out of everyone and everything.

One day, Terry heard of an endangered creature called "the Pupa" and turns out theres only one of its kind left. Terry and Jessie make it their mission to ensure this creature lives a safe, long life but when they find it in the hands of the Commodore Korvo, they are captured by the Commodore and his apprentice Yumyulack.

Now the two must not only survive on the fleet's ship but also find a way to save the Pupa from the mean (yet also strangely attractive) Korvo!
