Momoa, who previously appeared as Aquaman, said the character is one he has long wanted to play. Growing up, he dreamed not of traditional superheroes, but of a "cigar-smoking, motorcycle-riding bounty hunter," a vision that is now coming to life through the latest DC Studios project.

In the film, Lobo is depicted as an antihero with a rebellious edge. Momoa described what draws him to the role.
"I love the motorcycle, I love hair, the dreadlocks, you know," he said. "I loved that he didn't give a s***, he's an anti-hero. I love that he could fight everybody."
The character of Supergirl offers a very different take on Lobo. In one scene, she describes him as "an immortal with a god complex, killed off his entire planet, not a fun guy."
Despite their differences, the two characters share a common goal, as both are searching for the same group of brigands.
The film also highlights the pair's rough-and-tumble dynamic, including their shared tendency toward nightlife antics.
When asked if he or Supergirl would win in a drinking contest, Momoa said with a laugh, "I'm not even gonna answer that question, but it'd be a fun party!"
While the film leans into a gritty tone, it remains accessible to a broad audience. It is rated PG-13, and Momoa said he looks forward to sharing it with his family.
"That's the exciting thing about playing these superhero movies," he said. "Sitting with your family, because obviously I have kids, so watching with my babies. I'm excited to do that."
