In Fossil Fighters, the hero aims to become a master Fighter, as well as Rosie Richmond. Dr. Diggins is also a Fossil Fighter. To be a Fighter, one must have a Fighter's License. One can also participate in Level-Up Battles and rank oneself up to gain access to new Dig Sites.
The player can also choose to battle Fossil Fighters that are standing around at dig sites, usually for more BP than those who pop out of the ground.
