The Cephalon is a transparent extraterrestrial beast.
The Cephalon encountered the Interceptor crew and assaulted them in Frontier Space. It had the advantage, but was put to a stop by the power of love from the Star Sapphires, who calmed the beast down and left the scene.
When the Interceptor crew escaped from Zamaron, the Cephalon was summoned by the Star Sapphires to hold them on the planet, but its mission was put to a halt by Ghia'ta. The Cephalon calmed down and let the Interceptor crew escape.
