It’s difficult to definitively answer who the most brutal UFC fighter is, as it often depends on personal opinion and the particular techniques a fighter may have. Some fighters have been known to have a more fierce and damaging fighting style, such as Anderson Silva, Ronda Rousey, and Dominick Cruz. But there are also fighters like Chuck Liddell and Conor McGregor who have won a lot of fights with largely effective “brutal” techniques. Ultimately, there is no easy answer when determining who is the most brutal UFC fighter.
