Jason Momoa, known for his iconic roles as Khal Drogo in Game of Thrones and the heroic Aquaman in the DC Extended Universe, has a multifaceted life that goes beyond his stunning on-screen presence. From his early career as a model to his passionate advocacy for the environment, here are nine intriguing facts about the actor that every fan should know.

1. Early Life and Heritage
Born on August 1, 1979, in Honolulu, Hawaii, Jason Momoa has a rich cultural background that influences much of his work. Raised in Iowa by his mother, a photographer of mixed European and Native American ancestry, Momoa’s father is a Native Hawaiian painter. His heritage plays a significant role in shaping both his personal identity and career choices.

2. Modeling Beginnings
Before Momoa became a household name, he was discovered by designer Eric Chandler and Takeo Kobayashi in 1998 while working at a surf shop. This led to a successful modeling career, and in 1999, he was named Hawaii’s Model of the Year. His early exposure to the fashion world would later help him transition into acting.

3. Breakthrough Role in Baywatch: Hawaii
Momoa’s acting career took off with his role as Jason Ioane on Baywatch: Hawaii, which ran from 1999 to 2001. While this role was essential in launching his career, Momoa has since distanced himself from the show, preferring to focus on more diverse and dynamic roles.

4. Martial Arts Enthusiast
To prepare for physically demanding roles, such as Ronon Dex in Stargate: Atlantis and the titular character in Conan the Barbarian, Momoa dedicated himself to martial arts. He trained extensively in various disciplines, including Brazilian jiu-jitsu, which he began practicing in 2017. His commitment to martial arts is part of his overall dedication to physical fitness.

5. Avid Rock Climber
In addition to martial arts, Momoa has a passion for rock climbing, a hobby that keeps him grounded and in peak physical condition. While filming Aquaman in Australia, he even had a custom-built rock-climbing gym on set, demonstrating his commitment to staying fit while balancing the demands of acting.

6. Signature Eyebrow Scar
One of Momoa’s most distinguishing features is the scar above his left eyebrow. This scar was a result of an attack in 2008 when he was struck with a broken beer glass, requiring over 140 stitches. Rather than seeing it as a flaw, Momoa embraced the scar, acknowledging that it helped him land more rugged and intense roles, including the iconic Khal Drogo.

7. Family Man
Momoa is a devoted father and stepfather. He has two children, daughter Lola and son Nakoa-Wolf, with his ex-wife, actress Lisa Bonet. He is also a loving stepfather to Zoë Kravitz, Bonet’s daughter from her previous marriage to musician Lenny Kravitz. Momoa is known for his close-knit family values and frequently shares moments with his children on social media.

8. Environmental Advocate
Committed to sustainability and environmental conservation, Momoa founded a canned water company, Mananalu, in 2019 to combat plastic pollution. His advocacy for ocean preservation and sustainable living practices extends beyond his business ventures, and he continues to use his platform to raise awareness about environmental issues.

9. Recent Projects and Personal Life
In addition to his environmental work, Momoa has remained a key figure in Hollywood. He is set to play the antihero Lobo in the upcoming DC film Supergirl: Woman of Tomorrow, slated for release on June 26, 2026.
