Just like her brother, Pereira enjoyed a successful kickboxing career.
Her fights included a super-bantamweight title opportunity with Glory promotions, before she transitioned to MMA in 2022.
Pereira decided to step away from the sport in 2023 after her MMA career began with a rocky 1‑2 spell with Legacy Fighting Alliance (LFA).
She found momentum in Karate Combat League, going 3‑0 with two knockouts and winning the promotion’s inaugural women’s flyweight title in 2024.
The Brazilian returned to MMA in late 2025 and is often seen being trained and cornered by her brother, Alex.
Alex failed in his bid to become a three-weight UFC champion in June, losing to Frenchman Ciryl Gane in an interim heavyweight title fight.
Aline faces a tough opponent in Sundell, who has two wins in her MMA career to date.
The 21‑year‑old signed with ONE Championship in 2022 and won its inaugural women’s strawweight Muay Thai title at just 17 years and 161 days old, becoming the promotion’s youngest ever champion.
