Jack Quaid & Jensen Ackles on The Boys (2022)

Episode 4 of the third season of the Amazon original series The Boys marked the nude debut of cast member Jack Quaid. His character Hughie unleashed his superpower in an effort to come to the aide of his comrade Mother's Milk. This required his clothes to be left behind. He showed rear nudity for the scene. He was also present for another rear nudity debut later in the episode as the show's anti-super squad went looking for a mysterious weapon in their fight. This led to them awakening the superhero Soldier Boy (played by Jensen Ackles), who had been kept preserved for decades. He emerged from his tank naked, allowing for some brief rear nudity from Jensen as well.
