S1·E55 FM King Cepheus

The Satellite Administrators sacrifice themselves in order to destroy Andromeda. However, Gemini Spark White murders his other half to harness his minus energy and revive Andromeda once more, but Omega-Xis is able to crush the key before the Earth is erased. Afterwards, the FM-ians' king Cepheus descends onto Earth to take responsibility for his wrongful attacks on Earth, defeating Gemini White Spark personally. He also grants Geo the chance to speak with his father, although his father is not yet ready to return home. Pat's body is also discovered, with no memories of meeting Gemini and after. With the war against the FM-ians over, life is a lot brighter for Geo and his friends.
