Kelly wore a uniform of camouflaged pants and a jacket, and wore a dark green beret on his head. He appeared to be around thirty and had an air of casual professionalism to him.
Sec Chief Kelly, was the head of the sec men for the Greenglades theme park. He wasn't exactly the friendliest of the people, but he did try to warn Ryan and the group that Adam Traven had something in store for Ryan's son Dean. He also tried to get them to leave the park before Traven made his final bid to take over. In the end, because of his loyalty to Larry Zapp, he was thrown off a Paraglide Paradise ride to his death, taking one of the sec men who turned coat with him.
He carried a government issue colt .45.
