Amphibriar is original species made by Bubli Joestar. They're alien species with high intelligence, large and strong bodies. They come from planet Zharathik, a ruined planet far far away from out galaxy. However despite the planet ruination, Amphibriars were able to survive and rebuilds bits of the planet due to their high evolutionary abilities.
Aphibriars despite being highly intelligent, they're known for their resiliance, and trading. As their planet was partially rebuilt, it now functions as a space bay for trading ships.
In the past, Amphibriars were society of scientists, however after the ruination, most of the Aphibriars went down the path of space pirates. They became highly teritorrial and not quite approachable with lots of different alien.

One of the most known Amphibriar is Captain and his Axolocrew
