Greg Thorne



Greg Thorne, later known as St. George, is the main antagonist of The Enemy series and makes an appearance in all seven books. He is shown to be extremely intelligent and is blessed with the ability to lead armies of grown-ups throughout the whole book via the use of telepathy that all the grown-ups posses (this may be attributed to the fact that he was the last grown-up on Earth to be infected).

In When the Cold Breeze Blows Away, he leads the sickos and the rest of the South Vietnamese Umbrella Force to destory not only kid heroes, but also the remaining grownups as well (including the Viet Cong), as ordered by Nguyễn Văn Thiệu.
