** "[[Recap/StarTrekTheNextGenerationS3E22TheMostToys The Most Toys]]": Kivas Fajo is a CollectorOfTheStrange with the attitude of a [[PsychopathicManchild sociopathic brat]], who uses his job as a trader to cover for his thievery of unique and valuable objects. After desiring to add Data, the only known sentient android in the galaxy to his collection, he [[WaterSourceTampering poisons an inhabited planet's water supply]] so [[PoisonAndCureGambit he can kidnap Data and cover it up as an accidental death while trading over the antidote]]. When Data is in his care, Fajo [[ItIsDehumanizing doesn't care about his sentience]] and degrades and humiliates him into catering to his whims, insistent that he's just another shiny object. When Data refuses to comply, Fajo eventually forces him to obey by threatening to kill his broken, co-dependent slave girlfriend Varria with a Varon-T Disruptor, which is illegal to carry in the Federation due to the [[AgonyBeam agonizingly slow and torturous]] way it kills its targets from the inside out. When Varria helps Data escape, Fajo murders her with it and [[NeverMyFault pins the blame on Data]]. He then threatens to continue killing more of his own servants if Data keeps refusing to obey him, and even dismisses Varria's death by stating that he can easily find a replacement. Among the series's one-shot villains, Kivas Fajo is without a doubt among the worst.

[[WellIntentionedExtremist While most of the Xindi leaders]] express regret over [[IDidWhatIHadToDo what they have done]], but see it as a NecessaryEvil to save their civilization, Dolim revels in the fact that he helped to kill so many humans, gloating to Archer that he personally selected the pilot of the probe that attacked Earth. When Archer presents evidence that the Sphere Builders are lying, many of the reasonable Xindi leaders are convinced, but [[GeneralRipper Dolim will not even consider the evidence]].

He quickly realizes that he accidentally started the virus when he killed a Borg just as the [[SufficientlyAdvancedAliens Caeliar]] were [[AscendToAHigherPlaneOfExistence ascending them to a higher level of existence]], causing the catoms transforming it to bond with an airborne virus and mutate it. However, since Briggs sees the Caeliar as a threat to the Federation, he decides to try and control catoms under cover of supposedly searching for a cure. In fact, instead of quarantining the plague and allowing it to burn out, he [[SyntheticPlague deliberately spreads it]] to other Federation worlds, killing thousands. He has already used illegal genetic engineering to create a member of an extinct species whose genome he has been studying and creates 1,961 copies of her, most of which he kills by experimenting on them with catoms. He uses dubious means to co-opt a number of former Borg drones, including [[WouldHurtAChild children of former drones]], as a new source of catoms and, when he learns they [[ImHavingSoulPains feel the pain of the experiment subjects killed by their catoms]], is quick to use it as a [[MindRape means]] of ensuring their cooperation. In the end, the only solution the Federation can come up with is to imprison him somewhere where he'll never be heard of again.
