Bia was a Titan goddess in Greek mythology, daughter of the Titans Pallas and Styx, and had three siblings; Nike, Kratos, and Zelus. Bia was the personification of force. During the Titanomachy, the war between the Titans and the Olympians out of which the latter emerged victorious, Bia and her siblings sided with Zeus, along with Styx. To honour them, Zeus made the four siblings his constant companions.
