Verin
Verin was leader of his species, a species whose planet had been contaminated by the consequences of the information shared in an Earth probe called Friendship 1. That information caused the civilization to develop antimatter power generation. The explosion of an antimatter plant caused radiation sickness and a nuclear winter. When the  attempted to recover the probe, Verin took the away team hostage. He demanded that his people be relocated to another planet. When Janeway suggested an alternate plan, he killed Lt. Carey. As he prepared to fire a missile at Voyager he was deposed as leader by Otrin, who accepted Voyagers plan. ()
