[Rank/Name] Bolla [Weapons/Equipment] Rhino Gun [Description] 
A large, muscular, quadrupedal horned beast. Its supreme strength is bolstered by a bioform generator similar to that of a Rhino, which splatters opponents to death. The Bolla is only vulnerable to the spinal ridge, face and stomach. When a weak point is sufficiently damaged, the Bolla's life force is permanently damaged, but can no longer take extra damage from a dormant weak point. To defeat a Bolla is to destroy all three weak points. Sheridan takes on a unique grey/black Bolla form near the end of the game. He can summon Creepers to his aid, and once a weak spot is destroyed, he generates a force field powered by various spikes. Inside the force field. he will build up power and can fully restore the dormant weak point given enough time, forcing the player to destroy the same weak point again. On higher difficulties he may be supported by Spike Hydras as well.
