President Gerard Folsom

Gerard Folsom was the President of the Colonies, and Commander and Chief of the Human-Volterite Alliance. He worked with the Alien Overseer to use Volterite technology to fight and win against Earth N.O.V.A. troops. He came face-to-face with Kal Wardin in the Imperial Palace on Sky City, trying to convince him to give in, and, failing to do so, attempting to shoot him in the hopes he wasn't fully alert. This too failed, and he was successfully shot and killed by Kal an instant later.
