Mackenzie Dern is the UFC women's strawweight champion and one of the most decorated grapplers ever to enter MMA — a Brazilian jiu-jitsu world champion and ADCC gold medalist before she threw a punch professionally. Born and raised in Arizona and the daughter of BJJ legend Wellington 'Megaton' Dias, she finally captured UFC gold in October 2025, outworking Virna Jandiroba for the vacant belt. All eight of her career finishes are submissions, and her armbar is one of the most feared weapons in the division. Her striking has improved steadily, but the ground is where she wins fights. This is her first title defense.
