They call her “Psycho,” but it just doesn’t square when you talk to the ever-smiling Julia Polastri. Always quick with a laugh and radiant energy, her mood is particularly high as she prepares for her UFC debut in the building where she won her contract nine months ago on Dana White’s Contender Series.
“I was very happy when I knew that it was going to be at the UFC APEX because I had two fights in here. So I know the place and it's very comfortable.”
The thrill of her receiving her first UFC fight kit, the first bag of gear and her first round of press only beget more smiles from the Rio native as the realization of her dream is now just hours away. She’ll climb into the UFC Octagon as part of the prelim card for UFC Fight Night: Perez vs Taira.

The path to get here wasn’t a simple one, though. After a dominant run that saw her crowned the Shooto Brazil strawweight champion, Polastri came out on the wrong side of the scorecards in her first invitation to DWCS back in 2021. Her opponent that night, Jasmine Jasudavicius, would go on to the UFC. Polastri would go back to the drawing board and back to her winning ways.
Under the LFA banner, Polastri turned in back-to-back devastating finishes: a TKO and an arm triangle submission. Contender Series rang again. The opportunity was there—possibly for the last time—and she wasn’t about to let it slip away.
Saturday's Full Fight Card Preview
It was a truly incredible bout while it lasted, with Polastri and her opponent, Patricia Alujas, going nearly shot-for-shot throughout the first round for a staggering 291 total strikes combined. When the horn sounded, Dana White himself was on his feet and clapping. Someone was clearly going home with a contract that night, but Polastri was down on two of the judges’ scorecards.

Seemingly sensing as much, Polastri responded in kind, body-slamming her opponent to the canvas Jessica Andrade-style and giving her four minutes of one-way traffic that culminated in a rear naked choke with less than a minute to go in the second round. White congratulated her that night as she left the Octagon, and a short while later, she was the newest member of the UFC strawweight ranks.
All the winners on the Tuesday night institution are celebratory, but it was hard to remember one as happy as the Brazilian was that night. Even as she recalls it now, she smiles as all the good feelings seem to return to her.

“Brilliant, you know? Like, there was a glow on me, and I was radiant. I don't know if I'm saying it right, but it was like, I felt something…around me. I was just so happy and so excited and just wanting to do this again.”
After some fits and starts and cancellations, she’ll get to do it again this Saturday when she takes on Josefine Knutsson. Another alumna of DWCS, Knutsson already has a UFC win under her belt and will be putting her undefeated record on the line. In short, two fighters in a very similar position in their careers will enter the cage looking to make a statement.

“We are doing our best and we are trying to really prove ourselves, so the fight gets more exciting. I know that we are both gonna leave everything in the Octagon, and I think that is more exciting for the people that's watching and for the boss,” she smiles. “I’m excited for this.”

It might be a cliché these days to call a fighter “well-rounded,” but it’s hard to find a better descriptor when you’re discussing the 12-3 Polastri, a self-described striker who has nearly as many submission finishes as she does knockouts, and wields wrestling and jiu-jitsu as easily as she does her Muay Thai base. It’s this power—antithetical to her cheery disposition—that led to her nickname.
“I am a really nice person. Peaceful. I don't get stressed with anything. And when I get in the Octagon, (my coach) says that it's like I am cold and distant; like it's another person in there. It's not the Julia, it’s the Psycho. So he always called me psychopath. They are calling me ‘The Dragon,’ and I didn't like the nickname because I didn't think the fits with me. And then (coach) called me ‘bad psychopath.’ And I think, ‘oh, Psycho. I think that one fits better.’ So I started calling myself Psycho.”
So should the division be on the lookout…for a psycho?
“I'm here to stay, and I'm here to make history. I've been working a lot for seven years to get here. And since my first fight, I've always wanted to be here and to be the champion. So, it takes a long time to be here, but now that I'm here, I'm going to stay…forever.”
