The X's arch-enemy, leader of S.N.A.F.U, and the main antagonist of the series. 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 X's include having Trudy 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. Similar to Dr. Evil from Austin Powers, Doctor Claw from Inspector Gadget, Satan from South Park, Dr. Drakken from Kim Possible, Vito Corleone from The Godfather and Ernst Stavro Blofeld from the James Bond series, he also tends to think up idiotic evil schemes like building a giant ray gun in order to bring the Eiffel Tower and Big Ben to life in order for them to wrestle so he can sell tickets.
