Luxor is the Primary Antagonist, and the Leader of Team Nexus. It is unknown how old he is. Luxor's mission revolves around obtaining very Powerful Pokemon (many of them legendaries) and forcibly combining their power together and use the destructive force to take over the world and enslave Humanity. Throughout the series, he is constantly encountered by Alex and Theo, and yet he has always proved to be a very serious challenge for them both. It's believed that Luxor is even stronger than the Champion. Luxor is meant to be a combination of Cyrus, Ghetsis and Lysandre. 

The cold, heartless disregard and lack of Emotion from Cyrus, his decietful deeds, silver tounge and well played Facade of Ghetsis and the utter lack of compassion and pure contempt for Humanity of Lysandre.

He is known for often getting into fits of sheer rage, don't be afraid to show that.
