Ronda Rousey is dominating the sport of MMA at the moment.
Nobody can get near her at the moment - she's finished 11 of her 12 fights in the first round.
But if the 28-year-old undefeated bantamweight champion is still around in 10 years, she might have some very stiff competition.
The UFC posted a video of an eight-year-old Evnika Saadvakass with frankly terrifying boxing skills.
The Kazakh girl, who hails from the same country as knock-out merchant Gennady Golovkin, can throw 100 punches a minute.
We don't know what her judo or ground game is like, but we sure know we would not like to take a punch off her.
