You probably know her as the girl who just wouldn't stop talking about "the dripping" in that creepy attic. Or maybe you recognized her behind a high-tech mask, throwing light-shards at the fastest man alive. Whether she's surviving a plane crash or hunting down superheroes, Alexa Barajas movies and tv shows have quietly become a staple for fans of gritty, genre-bending television.
It’s actually wild how much she’s done without becoming a "paparazzi target" yet. Born in Mexico and raised in Vancouver, Barajas has that specific "it" factor—she can play the annoying teenager you love to hate or a cold-blooded assassin with equal believable energy. Honestly, her career path is a masterclass in "slow-burn" success.
The Yellowjackets Phenomenon: Is She Really Pit Girl?
Let's address the cannibal in the room. If you’ve spent any time on Reddit or Twitter over the last few years, you’ve seen the "Pit Girl" theories. For the uninitiated, Yellowjackets is the Showtime hit where a high school soccer team gets stranded in the Canadian wilderness and eventually starts eating each other.
Alexa plays Mari.
At first, Mari was just the girl who cooked the food and made snarky comments. But as the seasons progressed, she became one of the most polarizing characters in the show. Fans were obsessed with figuring out if she was the girl who falls into the spike pit in the series premiere.
Why Mari Matters
Most people think Mari is just a background survivor. They're wrong. Barajas brings a specific kind of "survival anxiety" to the role that makes the group's descent into madness feel real. While others are having visions or leading cults, Mari is just trying to stay fed and stay relevant. It’s a grounded performance in a very ungrounded show.

- The Big Reveal: Season 3 finally pulled the curtain back. After years of fan theories, we saw Mari's journey come "full circle." The tension Barajas built over three seasons made that payoff (or tragedy, depending on how you look at it) hit way harder than if she had just been some random extra.
- The Shauna Rivalry: The animosity between Mari and Shauna (Sophie Nélisse) became a highlight of the later episodes. It wasn't just about survival; it was about two people who genuinely couldn't stand each other even before the world ended.
The Flash and the Arrowverse Era
Before she was freezing in the wilderness, Barajas was a recurring villain in the CW's The Flash. She played Esperanza Garcia, better known as the assassin Ultraviolet.
It’s a complete 180 from her role in Yellowjackets. As Ultraviolet, she’s deadly, silent (at first), and incredibly physical. She was a member of Black Hole and the cousin of Allegra Garcia. The fight choreography she handled in those episodes was surprisingly intense for network TV.
If you go back and watch her scenes now, you can see the seeds of her later work. She has this way of using her eyes to convey a lot of internal pain without saying a single word. It’s basically the opposite of Mari, who never knows when to shut up.
A Quick Look at the Filmography
Barajas hasn't just stuck to TV. She’s been building a solid resume in indie films and TV movies that most people blink and miss.
ROMI (2023)
This is a hidden gem if you like "smart house" horror. She plays Maddie, a woman who hides out in a high-tech home that—surprise, surprise—isn't as safe as it looks. It's one of her few leading roles, and it proves she can carry a whole movie on her shoulders.

Endless (2020)
A teen supernatural romance. It’s not Citizen Kane, but it showed she could do the "heartfelt drama" thing before she jumped into the blood and guts of prestige horror.
Marrying Father Christmas (2018)
Yes, she was even in a Hallmark movie. Everyone has to start somewhere, right? She played a store clerk. It's a fun "Easter egg" for fans who want to see her in a setting where nobody is getting murdered.
Wayward Pines & Charmed
Small, one-off roles that helped her get her SAG-AFTRA card. In Wayward Pines, she was just getting her feet wet in the industry, but even then, she had a presence that caught the eye of casting directors.
What's Next for Alexa Barajas?
With Yellowjackets wrapping up its major character arcs and heading toward its final season in 2026, the big question is where Barajas goes from here. She’s already proven she can handle:
- Physical Stunts (The Flash)
- Ensemble Drama (Yellowjackets)
- Lead Suspense (ROMI)
There are rumors floating around about her joining a new A24 project, though nothing is set in stone. Given her track record with "elevated horror," that feels like a natural fit. She has that "Final Girl" energy, but with a twist—she’s just as likely to be the one holding the knife.

Why You Should Keep Watching
Honestly, the "it" factor is hard to define, but Barajas has it. She’s one of the few actresses who can make a character totally unlikeable and still make you want to watch them every second they’re on screen. Mari could be a total brat, but you still felt for her when things went south.
If you want to see the full range of alexa barajas movies and tv shows, start with the Yellowjackets pilot and then jump to her episodes in The Flash Season 6. The contrast is jarring in the best way possible.
Actionable Next Steps
If you're a fan or just curious, here's how to actually dive into her work:
- Watch ROMI on Tubi: It's free (with ads) and is the best showcase of her as a lead actress.
- Rewatch Yellowjackets Season 3: Now that the "Pit Girl" mystery is solved, her performance in the early episodes takes on a whole new meaning. Look for the small details in how she reacts to the "AQ" (Antler Queen) rituals.
- Check out her interviews: She’s known for being a massive Nintendo fan and often talks about playing Animal Crossing or Zelda to decompress after filming those brutal survival scenes. It makes her way more relatable.
She isn't just "the girl from that one show" anymore. She's becoming a powerhouse in the genre space, and 2026 is looking like it might be her biggest year yet as she transitions from ensemble player to a household name.
