WATCH: Russian slugger Natalia Diachkova turns from laid back animal lover to absolute beast in brutal highlight reel

Russian knockout artist Natalia Diachkova is both a lover and a fighter. On Friday, May 3, she could also become a world champion.

Emanating from the iconic Lumpinee Boxing Stadium in Bangkok, Thailand, ONE Championship returns with its latest Amazon Prime Video offering, ONE Fight Night 22. In the main event of the evening, reigning ONE women's strawweight Muay Thai world champion Smilla Sundell puts her belt on the line against fast-rising standout Natalia Diachkova.

Through her first four appearances, the 'Karelian Lynx' has proven to be a destructive force in four-ounce gloves, dispatching three of her opponents in the opening round. But as dangerous as Diachkova is inside the ring, there's a softer side to her outside of it — particularly when it comes to animals:

"Absolute BEAST. Can Natalia Diachkova dethrone Smilla Sundell to become the NEW ONE Women’s Strawweight Muay Thai World Champion?"

With a series of highlight-reel knockouts against Dokmaipa Fairtex, Lena Nocker, and Chellina Chirino, Natalia Diachkova will look to score the biggest win of her combat sports career and take 26 pounds of gold back home to her native Russia.

Natalia Diachkova calls out Smilla Sundell for fighting smaller opponents

Standing in Diachkova's way will be perhaps the greatest female Muay Thai practitioner on the planet today, Smilla Sundell.

Like her ONE Fight Night 22 opponent, 'The Hurricane' is a perfect 4-0 in ONE Championship with notable victories coming against Diandra Martin, Jackie Buntan, and current ONE atomweight Muay Thai world titleholder Allycia Hellen Rodrigues.

Though her resume is nothing short of impressive, Diachkova believes Sundell has grown accustomed to fighting women significantly smaller than her — a trend that will change when they step inside the ring inside the Mecca of Muay Thai:

"Because, as a rule, she didn't face the strongest opposition in the division," Diachkova told ONE. "Her rivals were so small! And that fight with Allycia [Hellen Rodrigues], this girl is underweight."

Will 'Karelian Lynx' be the one to dethrone the Swedish teen phenom and begin her reign at the top of the strawweight Muay Thai division?

ONE Championship fans in the United States and Canada can watch ONE Fight Night 22 live and for free via Amazon Prime Video in U.S. primetime on Friday, June 7.
