Negasonic Teenage Warhead was the first.
Deadpool 2 did something that no other big-budget superhero film has ever done before. The Marvel film placed a lesbian relationship in the movie, with Negasonic Teenage Warhead and Yukio enjoying a fun on-screen romance. The relationship earned Deadpool 2 the undying support of the gay community, along with several gay rights movements including GLAAD. Unlike many aspects of Deadpool 2, the lesbian relationship keeps things PG, and prefers to highlight the dynamics of Negasonic Teenage Warhead and Yukio instead of playing up their sexuality. Negasonic is played by Brianna Hildebrand, a real lift LGBT activist. In a recent interview with The Hollywood Reporter, Hildebrand admitted that Ryan Reynolds was the one who suggested the lesbian relationship be placed in the movie.
"I've had so many positive responses," Hildebrand stated. "It was Ryan's idea. I had already done a lot of work with It Gets Better, so I think maybe he had seen some of that. The response has been overwhelmingly positive." As for the future, Hildebrand was recently cast in Netflix's Trinkets, which based on the young adult novel from Kirsten Smith about three teenage girls. "I used to read a lot of books, but now I read scripts," Hildebrand continued. "For the most part, recently I've been really into strong female characters. This particular project has a lot of strong female leads."
