Mackenzie Dern is one of the most visible women’s competitors of her generation. Trained from childhood by father Megaton Dias, she won IBJJF Worlds black-belt gold in 2015 and 2016, took ADCC gold at −60 kg in 2015, and built a guard-centered identity around berimbolo and lower-body attacks.

She later transitioned into MMA and won the vacant UFC Women’s Strawweight Championship against Virna Jandiroba at UFC 321 in 2025. Her profile pairs with open-guard, berimbolo, and armbar pages for technique readers.
