Bio: Horrocks is one of Jamie Braddock's best buddies when they were young, together with Amina Synge and Godfrey Calthrop. They disappeared in a sandstorm on the Sahara Desert during a Trans-Sahara Ralye which only Jamie escaped. They were contacted by the First Fallen, and returned years later, trying to reach Jamie to complete the First Fallen plans, fighting the X-Men in the process. The First Fallen take the Foursakens and the X-Men to The Singing City, a "heaven" created by him. It is said that humanity will live on in this new place, but it is soon discovered only four humans will make the cut. All others will not.
In the climactic action, Horrocks attacks the First Fallen. The First Fallen takes retribution and kills Horrocks. The others escape when Jamie sacrifices himself and sends the others back to the 616 universe.
