THOSE ORIONS & THEIR IRRESISTIBLE PHERMONES!!!...

No, all Orion men aren't bald and big and fat... Some are quite fit and attractive.

But, Orions DO have a tendency to be criminal, and to, of course, deal in disreputable, ~ uh, occupations. Like piracy... They are unusual physically >>> Orions were known for their distinctive green skin, which could feature yellowish to bluish undertones. They usually had green or black hair, (TOS: "The Cage", "Whom Gods Destroy"; ST: "The Escape Artist"; LD: "Something Borrowed, Something Green") though some had red, brown or white hair. (Star Trek; Star Trek Into Darkness; LD: "Second Contact", "We'll Always Have Tom Paris"; DIS: "All Is Possible") Some female Orions were capable of emitting highly potent pheromones (sometimes referred to amongst Orions as "stink") that could impact the physiology of other species. In heterosexual males of many species, including Humans, the pheromones accelerated metabolisms, raising adrenaline production to dangerous levels. This could cause aggression and, after cumulative exposure, levels of delusion and suggestibility. The armpit area of such females were apparently an area of pheromone emission. Orion males were just as susceptible to these pheromones, and some would even choose to become addicted to them. (ENT: "Bound", LD: "Something Borrowed, Something Green")

These effects were not universal. Human heterosexual females reacted negatively to those same pheromones, experiencing headaches, while Denobulan males found their sleep cycles interrupted by them. Vulcans were immune to effects of the pheromones; this immunity could be shared by those who experienced a telepathic mating bond with a Vulcan. In 2154, Dr. Phlox of Enterprise NX-01 hypothesized that the pheromone acted as a defense mechanism against competition. (ENT: "Bound") Not all Orion women emitted or utilized such pheromones, nor were all Orion women even capable of doing so. (LD: "We'll Always Have Tom Paris", "Hear All, Trust Nothing") In the 2150s of the mirror universe, Orion women served in the Imperial Starfleet alongside men from many subject species of the Terran Empire without incident. (ENT: "In a Mirror, Darkly") In 2258 of the alternate reality, Orion women commonly served in Starfleet alongside men of many species without exerting any undue influence over them. In 2380, an Orion woman named D'Vana Tendi served aboard the USS Cerritos alongside men from species including Humans, Bajorans, Andorians, and Bolians without pheromones having any noticeable effect. (LD: "Second Contact") In 2381, she stated that she was unable to emit pheromones at all. When a Nausicaan suggested Tendi might use pheromones to gain advantage in a game of dom-jot, she replied, "I'm not even that kind of Orion!" (LD: "We'll Always Have Tom Paris") Later the same year, she reaffirmed this: when Mesk joked that she was emitting "aggressive female pheromones," she replied, "We don't all have those!" (LD: "Hear All, Trust Nothing"). She developed a chemical capable of temporarily neutralizing the pheromones of other Orions no later than 2381. (LD: "Something Borrowed, Something Green") Orions were immune to the hallucinogenic effects of nitrous oxide. (LD: "Room for Growth") ~ From "Memory Alpha Fandom".
