#4 UFC women's bantamweight and featherweight champion Amanda Nunes
A list of the best UFC knockout artists would be incomplete without the presence of women's bantamweight and featherweight champion Amanda Nunes. Winning and defending both titles with incredible ease, 'The Lioness' is undoubtedly one of the best UFC fighters of all time.
Nunes has six knockout wins at bantamweight, the most in the history of the division. Apart from a host of other records, she is on a massive 12-fight win streak at the moment, with knockout victories over Holly Holm, Cris Cyborg, Raquel Pennington, Ronda Rousey and Shayna Baszler.

One of the most fearsome punchers and well-rounded fighters women's MMA has ever seen, Nunes seems set to rule over both her divisions for at least a few more years.
#3 UFC light heavyweight Jiri Prochazka
While Amanda Nunes has been in the UFC since 2013, light heavyweight Jiri Prochazka is only two fights old in the promotion. But 'Denisa' has already developed a reputation for being devastatingly powerful, accurate and unconventional.
Prochazka's MMA record speaks for itself. Only two of his 32 professional MMA fights have gone to the judges, with an astonishing 25 knockout wins and a finishing rate in the high nineties. He has knocked out each of his last 10 opponents, with Dominick Reyes and Volkan Oezdemir finding themselves on the receiving end of his power in the UFC.
Prochazka is only 28 years old and has a lot of room to improve as a fighter. He is already one of the best knockout artists in the UFC today, though.
