Synopsis:
John Grimm was born a throwback. His appearance and strength resemble that of a caveman. Society shuns him due to his strange appearance. When his parents die in an auto accident, Grimm snaps.

Grimm becomes Caveman and begins wrecking cars. Wildcat and Stretch encounter Grimm on the road and fight him. Stretch wounds Caveman, but is unable to capture him.

Grimm then builds a cult of natue lovers. He convinces them to start a destructive war on society. Joan Fortune infiltrates the cult and passes information back to Stretch and Ted Grant. Stretch and Ted (as Wildcat) then shut down the cult and defeat Grimm.
