Ouranos was birthed by Gaia, his future wife, alone. Eventually he reigned over the universe. One of his sons later rose to overthrow him after he tried to banish him (and others) to deep in the Earth.
One time, Loki ends up in the hands of the giant, Thiazi, who threatens to kill Loki unless he brings him the goddess Idun. He agrees, but brings her back to Asgard for the gods. Thiazi chases him, but the gods light a fire around their fortress. The flames catch Thiazi and kill him, while Idun and Loki reach the gods safely.
