A schoolgirl ninja showed incredible strength by destroying her adult coach in a warrior-style race in stunning video that has been viewed more than 48 million times.
Taylor Jo Greene, 10, took up the sport less than 18 months ago but swings from bars, pulls herself up ropes and balances on huge rubber balls like a pro.
The youngster quickly mastered obstacles like the menacing warped wall - a vertical 14ft ramp - thanks to weekly training sessions with parkour coach Austin Gray.
Talented Taylor Jo, from Colorado, USA, even showed up another instructor at her local ninja gym when he challenged her to a race and she won.
Jaw-dropping footage of the feat, filmed in November, has been watched by more than 48 million people online, earning her praise from masters of the sport.
