'Onslaught' Star Adria Arjona Goes Full Prehistoric Glam for Halloween

Adria Arjona has had a breakout few years in Hollywood. After starring opposite Glen Powell in ‘Hit Man’ and playing Bix Caleen in the acclaimed ‘Star Wars’ series ‘Andor’, the actress has quickly become one of the industry’s most in-demand stars.

This year has been especially busy. Arjona led Adam Wingard’s A24 action thriller ‘Onslaught’, which she also executive produced, playing a traumatized army veteran who spends one terrifying night fighting off genetically modified soldiers.

For Halloween, Arjona traded her red-carpet gowns for something far more primal. Photos shared on Instagram show the actress in a prehistoric-inspired costume that quickly caught fans’ attention.

Arjona wears a glossy cropped top and matching mini skirt covered in an orange-and-black cracked-stone pattern. Small bone-shaped accents hang from the waistband of the skirt, giving the outfit a playful Stone Age feel.

She completed the look with a chunky gold necklace of spiky pendants, bone-shaped clips in her long, wavy hair, and black fur cuffs on her wrists and lower legs. Posing with her arms raised above her head, she fully commits to the cavewoman glamour.

The costume is a big change from Arjona’s recent fashion moments. During the ‘Onslaught’ press tour, she wore a series of monochrome looks styled by Dani Michelle, including a cropped leather moto set and an all-white Victoria Beckham gown.

Just a couple of weeks ago, she also turned heads at the Academy Museum Gala in Los Angeles. She wore a custom strapless black Rasario gown with a sculpted white neckline, paired with Tiffany & Co. jewelry.

Her Halloween look shows she’s just as comfortable having fun with a costume as she is on a formal red carpet. Arjona has a packed slate ahead. She stars opposite Michael B. Jordan in ‘The Thomas Crown Affair’, which is in post-production for a 2027 release.

She’s also part of James Gunn’s DC Universe film ‘Man of Tomorrow’, though DC Studios hasn’t confirmed which character she plays. Fans have speculated she could be Wonder Woman, but Gunn has pushed back on that theory, and nothing has been confirmed.

Arjona has teased her mystery role while staying careful about details. In comments shared online, she said she loves her costume, noting that both characters fans have guessed have great costumes if you’re a comics fan.

Beyond those big releases, Arjona has several other projects in the works. She’s attached to the erotic thriller ‘Scorn’, the film ‘Copperhead’ and the TV series ‘Criminal’, where she plays Greta.

With so much on the horizon, her Halloween look offers a fun break before another busy year. Fans will soon see her in a very different costume when ‘Man of Tomorrow’ arrives. Celebrity Halloween costumes this year have ranged from horror icons to beloved film characters.

Arjona’s prehistoric glam take stood out for its bold colors and playful details. Whether she’s fighting off soldiers on screen or channeling the Stone Age, Arjona clearly knows how to make an entrance.
