Fossil Fighters

Fossil Fighters are an organization of paleontological competitive monster fighters, who battle each other using creatures revived from dinosaur fossils called Vivosaurs. Fossil Fighters scour various dig sits to discover new fossils that can be turned into Vivosaurs. All Fossil Fighters must have a valid Fighter's License before being able to legally convert fossils into Vivosaurs. The Caliosteo Cup is the premiere Fossil Fighter championship, held yearly in multiple locations.
