Robert Pattinson says he is OK with his Batman getting a Robin in the future but on one condition – he has to be a 13-year-old.

Pattinson, who is playing the superhero for the first time in Matt Reeves' upcoming reboot "The Batman," said he would gladly introduce Robin but he should "be 13." Robin has appeared as Batman's sidekick in multiple DC comic books.

"Yeah, but he has to be 13," the 35-year-old actor said in a press conference Tuesday, ScreenRant reported. "That's the only way I'll accept it."

"No, I love Death in the Family and stuff, but I think it'd be so cool," he said referring to the 1988 comic book penned by Jim Aparo and Jim Starlin. In the book, Robin's character gets killed by the DC's iconic supervillain The Joker.

"Also people are so scared of it, but it's kind of exciting. I think it would be a really fun addition," Pattinson added.

Reeves, who was also part of the interview, agreed with Pattinson, saying he also loves "Death in the Family" comics.

"I also like 'Death in the Family.' And I think the idea of being able to approach some of those stories and think, 'How can we do this in a way that feels fresh and ground it in a way like, 'Look at the scary thing' and see if there's a way to do it," he explained.

While Reeves seems to be equally excited to explore Robin's character, it will be interesting for the fans to watch the upcoming "The Batman." The director had earlier opened up about the backlash Pattinson received for playing Batman in the new movie.

"There has been no actor, when his announcement that he was going to be playing Batman in one of the feature films was announced, that has not received a backlash," Reeves told Esquire last month.

The flick is slated to release in theaters on March 4 and will start streaming on HBO Max from April 19. The movie will also star Zoë Kravitz, Paul Dano, Colin Farrell, Jeffrey Wright, Barry Keoghan and Andy Serkis.

Pattinson was featured in movies like "The Devil All the Time" and "Tenet."
