Floyd Mayweather would be wise not to underestimate opponent Tenshin Nasukawa, as the 20-year-old kickboxing champion is a natural phenom.
With multiple world titles to his name and a slew of highlight reel knockout victories, Nasukawa is taking the Japanese combat sports world by storm and has all the makings of a superstar.
In his latest outing under the RISE banner, the featherweight kickboxing champ steamrolled opponent Taiki Naito inside the first round to earn yet another impressive stoppage victory.

A 16-year-old Nasukawa also knocked out Naito with a headkick back in 2015.
