Y: The Last Man is a post-apocalyptic comic book series created by writer Brian K. Vaughan and artist Pia Guerra. It takes place in a world where all mammals with a Y chromosome suddenly die, except for one man named Yorick Brown and his pet monkey Ampersand. Yorick sets out on a journey to find his girlfriend and uncover the truth behind the global catastrophe. The comic has been adapted into a TV series on FX on Hulu, which has been praised for its compelling storytelling, strong performances, and exploration of gender dynamics in a world without men.
