Xin Wuku

Xin Wuku appeared on Season 2 of American Gladiators in 2008. He was a gladiator dubbed "Zen" because that would be what his name would sound like.

On American Ninja Warrior, Xin was a fierce competitor. He struggled early on the Rope Swing, when he took three tries to reach the other side, resetting twice. He then moved quickly through the next four obstacles to become the second finisher, 27.3 seconds faster than the previous finisher, Daniel Devane. Unfortunately, it wasn't fast enough to qualify for the Semi-Finals.
