Xan. An alien from "a far off planet" whose father, Vyl, died in a space prison some time after his arrest at the hands of Superman and Batman.

The attempt is foiled when Meach takes the blast himself in a final act of self-sacrifice. The heroes subdue Xan, who is "incarcerated on his own world." (WF No.
