The Cave Bears are a group of prehistoric teddies that lived in the times of prehistoric Mobius. They seem very primitive and are quick to violence, however they know how to tell good from evil. They are lead by a king who is much older than the common bear, he has lost most of his hair and wears a crown.
When the Cave Bears see Robotnik and his goons going towards the Volcano where the Chaos Emerald of Life is hidden, they attack with their clubs, but are quickly out muscled by a robot T-Rex that was roboticized by Robotnik's Robot-Transmogrifier Ray. The Bears are rescued by Sonic the Hedgehog.
The Cave Bears later assist Sonic in blitzing Robotnik before he sacrifices Scratch and Grounder to Magma the Volcano God however they are too late. Robotnik uses his Lava Monsters to throw the cave bears into the volcano, but they are once again saved by Sonic.
