Gundam Wing: Return of Epyon

Chapter 1: The Nightmare

There was an explosion. Voices everywhere. Suddenly, the whole colony was ravaged by a purple gleam.
Two red eyes appeared; Two evil red eyes, yet strangely familiar. They gleamed in the moonlight, as an evil, high-pitched voice screamed and laughed. A bright light passed over the eyes, the laugh. A mechanical body, violet was seen. Then it all disappeared.
Relena Peacecraft opened her eyes, and gasped. She is the heir of the Peacecraft family, a family believing only in peace, abandoned by her brother, Milliardo Peacecraft.
What she had seen was a mobile suit, a robotic machine piloted by a human that had much destructive power. But this was not a normal mobile suit... it was a Gundam.
A Gundam is a very special type of mobile suit. Five were originally created by five brilliant scientists from the colonies, to stop OZ from taking over Earth and eventually the Colonies. They had destructive power to match 100 normal mobile suits. Later on, they were destroyed one by one. The Gundam pilots created newer Gundams, twice as much power as the originals. They together defeated OZ, and stopped Milliardo Peacecraft, his 6th Gundam, and his insanity from destroying the Colonies. He later safely returned to help them destroy a greater evil.
Relena recognized the Gundam as not one of the original five pilots', but of her brother's... the evil Gundam that drove her brother mad... the Epyon...
