the original five members could create it, but it was later discovered that Thomas Boyd could also contribute to it. Still later, Lindsey Falmon helped create it (who was neither on Proudhawk's list, nor did she have any memories of Proudhawk or Psi-Hawk). It has been created by as few as two and as many as six; however, on the one occasion more than five members participated, Psi-Hawk became dangerously unstable and began attacking those who created it until one of them fell unconscious. Any time a member wanted to leave the group and strike out on their own, they soon felt an irresistible mental urge to return (or, if they were able to withstand it, for the rest of the group to follow). This bound the group together, unwillingly, until Sanctuary was destroyed and they fled in several directions (although Crawley was able to leave earlier, so long as he was replaced by another member on Proudhawk's list), and never seemed to feel the compulsion. At the end of issue #24, Tucker, Jessup, Boyd, Ling, and Lindsey Falmon created the Psi-Hawk for the last time. This time, whether due to the group's relative experience, or because of the addition of Falmon's powers to the link, the five paranormals lost consciousness and actually controlled Psi-Hawk directly. In the fight with Rodstvow that ensued, Psi-Hawk was destroyed (although those creating it survived, falling into a coma). The series was noted for the characters more confrontational interactions with others, particularly authority figures. They came into conflict with many different groups which wanted to capture them including both the Soviet and American governments. Early issues of the book stressed the nature of the team as one of runaways. When Fabian Nicieza took over writing chores the stories began to focus more on the groups interactions with various paramilitary organizations. At one point, one of their number, Thomas Boyd, was drafted into the US military and the remaining members staged a raid on a US Army base to rescue him. Nicieza also introduced the shadowy Medusa Web organization, a group of mercenaries/terrorists who were occasional opponents and occasional allies of the group. Towards the end of the book's run Psi-Force spent some time at a Siberian training facility for Russian paranormals. When the Russian paranormal Rodstvow, who had been a repeated enemy of the group, showed up the teens teamed up with the Medusa
