YMMV / Star Trek: Deep Space Nine S01E09 "The Passenger"

• Complete Monster: Rao Vantika was a member of a dying alien race called the Kobliads. Vantika was obsessed with becoming immortal, performing experiments on prisoners. Eventually captured, Vantika sets fire to the ship carrying him. When Dr. Bashir arrives to give medical aid, Vantika secretly transfers his mind to Bashir's body. Meanwhile, Deep Space 9 is about to receive a shipment of deuridium, a chemical the Kobliads need to survive and prolong their lives. Vantika plans to steal the deuridium for himself to continue his experiments, not caring about the suffering of his countrymen. Vantika hires some mercenaries to help him steal the shipment and uses a runabout to highjack the freighter carrying the deuridium. After foiling an attempt by Vantika to cripple the station with a computer virus, the crew of Deep Space 9 lock on to the freighter with a tractor beam. Vantika threatens to send the freighter into warp, which will break apart the freighter and spread deuridium across the Bajoran solar system, making it uninhabitable, if Sisko does not let him escape. When one of the mercenaries decides to back out, Vantika coldly guns him down.
• Fridge Brilliance: It's Bashir who first mentions Kajada as a suspect.
• Narm: Alexander Siddig was faced with conveying that Bashir's body was occupied by an entirely different person, but clearly didn't want to go the route of just acting like a mustache-twirling serial villain. He apparently settled on delivering his lines in a sort of flat monotone and deliberately stilted cadence that makes Vantika sound like a bad text-to-speech computer program. It does accurately portray that he's not Bashir at the moment, but Vantika comes off as less cold and calculating and more like a malfunctioning Lore.
  • The producers weren't happy with Siddig's original vocal delivery and actually made him redub Vantika-possessed Bashir. This did not go well.
