Taufatofua was Tonga's flag-bearer at the opening ceremony in Rio and quickly became a social media darling after his topless display.
But now he is hoping to swap taekwondo for, of all things, cross-country skiing.
But can he really make it to the 2018 Winter Olympics in Pyeongchang? Watch this space!
The Jamaican superstar, who has won nine gold medals at three Olympic Games, announced this week that his final competitive race will be at the World Championships in London next summer.
Bolt turns 31 in 2017 and has admitted he wants to end his athletics career at the peak of his powers.
And Coe, who knows the world's fastest man better than most on and off the track, revealed to Sport360 that he has already approached Bolt about keeping him in the sport after retirement.
"(I have said to Usain) I want you to know that you have an open house to stay inside our sport and I have already started to talk to him about the type of role he will want to play going forward," the two-time Olympic gold medallist and former London 2012 supremo said during his visit to the General Authority of Youth and Sports Welfare in Dubai.
“The procedure for the next Olympic Games is underway and I can imagine one day Qatar would be a candidate for hosting the Olympic Games,” said Bach.
He was speaking in the Qatari capital Doha, the venue for the Association of National Olympic Committee’s General Assembly, which begins on Wednesday.
He is the latest world athletics boss to give his backing to a potential Qatar bid in the past few weeks.
Just last month, the president of the International Association of Athletics Federations (IAAF), Sebastian Coe, said a Qatari Summer Olympics was possible.
And he added that Olympic bosses could move the games to later in the calendar year if the Gulf country ever successfully bids to host the Games, to avoid its fierce summer heats.
Qatar, which will host the football World Cup in 2022, has publicly stated that it will bid for a future Olympics, with 2028 being a likely contender.
It unsuccessfully bid for the 2016 and 2020 games. Qatar will also host the 2019 World Athletics Championships.
