Annis Coo was the adventuring partner (aka: damsel constantly in distress) of Jim Casey, the Atomic Man. Her father, Prof. Coo, had created the Atomic Machine that accidentally exploded and gave Jim Casey the super strength he needed to become Atomic Man! In one adventure, the two of them adventured in the underground city of Atomica, which is inhabited by 9-foot tall giants. Whether or not they encountered King Grim the First and Only in that same subterranean land is unknown.
