WATCH: The moment Thai megastar Rodtang Jitmuangnon sized up Japanese icon Takeru Segawa in Bangkok

Reigning ONE flyweight Muay Thai world champion Rodtang Jitmuangnon might be one of the most terrifying fighters ever to step foot inside the circle. However, his larger-than-life personality outside of it makes him supremely relatable to many fans.

'The Iron Man', who attended ONE Friday Fights 81 this last Friday, Sept. 27, inside the Lumpinee Stadium in Bangkok, Thailand, had another memorable moment when he put on a straight face as if he was unimpressed with Takeru Segawa and his dazzling robe while the Japanese star made his ring walk.

Watch Rodtang's hilarious reaction to Takeru's ring walk, which ONE shared on Instagram:

ONE Friday Fights 81 was a memorable event for 'The Natural Born Crusher', Rodtang, and the fans who watched live via pay-per-view at watch.onefc.com.

The Japanese kickboxing great earned his first victory under the ONE banner with a marvelous come-from-behind knockout of 19-year-old Burmese standout Thant Zin.

Following Takeru's win, Rodtang entered the circle for a staredown and received an electrifying callout from the Team Vasileus star, which the Thai hero gleefully accepted by promising him an all-out war.

Takeru even more excited to fight Rodtang following ONE Friday Fights 81 faceoff

The impending megafight between Rodtang and Takeru gained even more hype when the former shoved the latter during the faceoff, which forced ONE officials to step in between them.

Takeru, however, is taking it all in stride, as he told Nick Atkin in the post-fight interview:

"No, it made me happy. Because it also showed that Rodtang accepts me as his rival. Rodtang showed me that emotion."
