While no other “Star Trek” character can touch Kevin Uxbridge on this front, he’s not the only entity in the franchise with plenty of blood on his hands. Despite his dangerous nature, Kevin isn’t a villain in the strictest sense of the term — if only because his crime is so complex and massive that Captain Picard (Patrick Stewart) essentially backs away from the situation, leaves Kevin to his own devices, and records a log that advises the listener to do the same.
Since the tragic, disgraced Douwd is on a level of his own, this leaves Eric Bana’s Nero as the most dangerous “Star Trek” villain. Not only does the Romulan antagonist in J.J. Abrams’ 2009 “Star Trek” movie create an entire new “Star Trek” Kelvin timeline, but because he destroys the planet Vulcan, his kill count is around six billion victims.
Another antagonistic character whose kill count is in the billions is the intelligent and omnicidal space probe Nomad MK-15c, which kills four billion Malurians before “Star Trek” Captain James T. Kirk (William Shatner) and his crew manage to stop it in the original show’s Season 2, Episode 3, “The Changeling.”
