While Pedro Pascal, who plays Richard Reed AKA Mr. Fantastic, doesn’t currently own a furry friend, he’s a massive dog lover. In a June 2025 interview with Vanity Fair, Pascal spoke warmly about his beloved late Pit Bull named Gretta. According to Pascal, his rescue pup provided him comfort after his mother passed in his early 20s. 

“She saved my life, that dog, because she gave me someone to go home to,” said Pascal during the interview.
