They're both Olympians, but who would win if Taekwondo gold medallist Jade Jones took on Christian Malcolm in a fight?
The former 200m sprinter was sent by Sport Wales to find out more about Jones, nicknamed The Head Hunter, as she prepares to defend her title in Rio 2016.
Jade tells Malcolm she wants to become "a legend" by winning a second Olympic Taekwondo gold medal. The 22-year-old Welsh competitor took the -57kg title at London 2012 when still a teenager.
