The Xs' arch-enemy and the leader of S.N.A.F.U. Glowface's head is encased in a glass globe with electrical discharges. He wears a rubber suit and gloves to contain his vast energies. His schemes to get rid of the Xs including having Mrs. X break her leg on a coffee table and sending them coupons for family portraits. Like traditional evil villains, Glowface is megalomaniacal, arrogant, loudmouthed and delusional, but he possesses little sophistication or maturity, and believes himself to be much more of a threat than he actually is.
