Perhaps you could go into detail about the agent corps--their numbers, their weapons and equipment, their motivations, and so forth. I had this guy in mind for the leader of the corps--
COMMANDANT SAVAGE
As a boy growing up in Mexico Sergio Garcia dreamed of being a soldier, a leader of men, fighting glorious battles and winning great victories. He joined the Mexican Army as soon as he was old enough, but fighting the minions of drug cartels wasn't quite what he was looking for. When VIPER made an offer, he took it--but starting at the bottom of a world-spanning organization meant starting a very long way down. Then he heard about Terror, Incorporated--smaller than VIPER, but with great potential. He sabotaged the Nest base and fled with millions of dollars in cash and materiel, and presented it to Meurte with this offer--"Appoint me as the leader of you forces, and I will build you an army worthy of a conqueror such as yourself."
As Commandant Savage, Garcia has made good on his offer and then some. The agents of Terror, Inc. are a fighting force with which to be reckoned. And while Meurte respects Savage and appreciates all he's done for him, he still keeps a very close eye on the man, for such exceptional talent and motivation goes hand-in-hand with exceptional ambition.
Hope that helps.
