Gene Roddenberry and the other ingenious minds behind Star Trek have come up with some brilliant technology for the Star Trek universe: warp drive, food replicators, the Holodeck, and one of the most fantastical of all: Star Trek transporters.

Imagine a world where commuting to work doesn't exist; you just beam yourself over. A world where you never have to worry about being late to a movie or business meeting. Where you can travel great distances in a matter of seconds. Sounds great, right? Well, maybe you'll reconsider when you think about all the things that can go wrong. Transporter malfunctions happen, and they're not pretty. Below, you'll find a veritable cornucopia of horrifying Star Trek transporter accidents. Vote up the ones that will make you rethink ever wanting to step on a transporter pad.

    The crew of Star Trek: the Original Series learned the hard way - don't have magnetic dust on your suit when beaming back up to the ship. The result? Two separate Captain Kirks, one good but incompetent, the other... pure evil.

    On an away mission, Commander William Riker came face to face with... himself! As it turns out, eight years ago, while serving on the USS Potemkin, a transporter malfunction caused the creation of a duplicate Riker (dubbed Lt. Thomas Riker). Thomas was brought aboard the ship, butted heads with William, and rekindled his relationship with Deanna Troi before ultimately being reassigned to the USS Gandhi where he could continue his Starfleet career.

    • Episode: Season 2, Episode 24, "Tuvix"

    Tuvok and Neelix beam back aboard after an excursion to an alien planet to retrieve some plant samples. Unfortunately, one of the orchids they brought back with them is the cause of a disturbing transporter accident that ultimately merges Tuvok and Neelix into one being - Tuvix. The crew accepts Tuvix for what he is (after all, they are on a journey to seek out new life forms), but things get complicated when the Doctor finds a way to reverse the process. By Captain Janeway's orders, Tuvok and Neelix are both restored, but Janeway has to live with the moral consequences of destroying the being known as Tuvix.
