Brianna Hildebrand has left fans doing a double-take after a viral comparison showed how different she looks from the character that made her famous as a teenager.

The actress became instantly recognizable as the brooding Negasonic Teenage Warhead in Deadpool , but an off-screen photo shows a completely different side of the star.

“I did not recognize her for a moment. That’s crazy ,” one fan wrote online.

Hildebrand rose to fame in 2016 when she was cast in Deadpool , playing the sarcastic, rebellious X-Men trainee alongside Ryan Reynolds.

She returned as the character in Deadpool 2 and later Deadpool & Wolverine , making the role a defining part of her career.

That contrast makes the viral side-by-side shared on X particularly striking.

One image shows Brianna in her instantly recognizable superhero persona, complete with the character’s severe styling and famously unimpressed expression.

The other shows the actress smiling cheekily as she stands in front of an outdoor shower in an orange bikini.
