The Creature of Ghost Lake is a subterranean monster who grew to an incredible size when exposed to a special serum. Its origins are unknown, but they believe it to have come from underneath Earth's surface. The serum that caused it to grow was developed by a man named Professor Duane, who mysteriously disappeared. When the monster began terrorizing Ghost Lake, the Suicide Squad were called in to stop it. The monster picked up a nuclear bomb from a testing site, and kidnapped Karin Grace. It walked into a well-populated city, where millions would die if the bomb went off. Rick Flag managed to save Karin Grace, and they sent the creature into a sinkhole. The creature plummeted into the depths, where the bomb killed it alone.
