Counter Strike

Counter Strike is the name of an organization of aliens, who come from the same mysterious species as the Aegis. Unlike their Aegis cousins, Counter Strike is a malevolent organization, devoted to cutting down civilizations that develop too far, too fast. They have devastated countless worlds directly, although certain worlds have been able to resist them. The Vulcans are one race known to have survived Counter Strike influence. However, since a number of races have resisted violently, they've become more subtle in their subversive tactics, giving certain species very destructive weapons. It's quite possible that [{Earth]] was one of the planets affected this way. (TOS Comic: Assignment Earth:#5)
