Trevor Vaughn

Trevor "Tre" Vaughn is a student/traceur with APEX Movement from Longmont, Colorado who first appeared in American Ninja Warrior 2. He amazed everyone with his speed in the qualifying round, getting first in the qualifer with 39.05 seconds. In the semi-finals, he didn't retain the same speed as his qualifying round, instead looking to clear the stage to ensure a spot to Boot Camp. However it didn't go as planned when he failed the Salmon Ladder due to losing his grip after the first jump, similar to David Money's earlier fall. He placed 21st overall, and did not move on.

In American Ninja Warrior 3, he was expected to be a threat to make it to Boot Camp due to his speed and improving his skill after practicing on a Salmon Ladder replica. In an unexpected moment, Vaughn slipped on the Quad Steps, ending his run early. He was visibly annoyed during his post-run interview, explaining that his failure was due to a previous competitor's fail on the same obstacle, coating the step with water. This made the obstacle slippery and harder to complete. His fail was arguably one of the most shocking of the qualifying round.

He returned to compete in American Ninja Warrior 5, earning redemption by clearing the Denver qualifier. But sadly in the Denver Finals, he couldn't pass the Fuandou, and did not move on.
