Viewers discovered many particulars concerning the Breen physiology via throwaway “Star Trek” dialogue. In “The Loss,” a “Subsequent Technology” episode that finds Troi (Marina Sirtis) quickly shedding her empathic skills, Information (Brent Spiner) reveals that the Breen are a uncommon instance of a race that’s undetectable to empaths — a trait helpful to a reclusive species. Information later considers the Breen as attainable culprits for an assault on a Federation ship in “Hero Worship,” citing the Breen’s close by outposts, cloaked vessels, and comparable battle techniques. Within the “Deep Area 9” episode “In Purgatory’s Shadow,” Bashir (Alexander Siddig) hints on the Breen’s gelatinous physiology, noting that the species doesn’t have blood.
Different particulars which can be revealed via the collection recommend that there is a sure diploma of delusion and misinformation surrounding the species. In “Indiscretion,” Gul Dukat (Marc Alaimo) referred to the Breen homeworld as a “frozen wasteland,” noting that the dilithium-rich desert planet Dozaria would have been “about fifty levels too sizzling for them.” However that is contradicted in “The Altering Face of Evil” with Weyoun’s (Jeffrey Combs) revelation that intelligence studies calling their homeworld a frozen wasteland are incorrect because the planet is definitely “fairly comfy.”
Within the “‘Til Loss of life Do Us Half,” Trill Ezri Dax (Nicole de Boer) speculates to Worf (Michael Dorn) concerning the species’ look. Whereas Ezri hypothesizes that the Breen could be “all furry” since Breen is alleged to be a chilly planet and shares a dream that they’ve giant claws, Worf has just one concern — how harmful and illiberal of different species the Breen are. In line with Worf, the Breen had been liable for the disappearance of a complete fleet of Klingon ships foolishly intent on conquering their homeworld.
