Deren Perez

Deren Perez is a coast guard from Guam and also lives in Plymouth, England. Though he resides in a U.S. territory, Perez actually has dual-citizenship in both the United States and the United Kingdom, and as such was able to compete on both American Ninja Warrior, Ninja Warrior UK, and SASUKE Vietnam.

American Ninja Warrior 9
Perez competed in 2017 in American Ninja Warrior 9's Kansas City course. In qualifying, his run was cut but he failed Crank It Up, placing 27th overall and advancing to the city finals.

In the city finals, he failed Crank It Up again. He placed 22nd overall, and therefore didn't advance to the national finals that season.

Ninja Warrior UK 4
Perez later competed in Ninja Warrior UK 4 in 2018. In this competition, he performed exceptionally, placing 1st in his heat, Heat 2, and later going on to clear the semi-finals course placing 7th.

In the finals round, he finished stage 1 with 117 seconds left. He remarkably finished stage 2 with 37 seconds left on the clock, and became one of only five remaining competitors to make it to the third stage. Finally, he made it to the Flying Bars before fatiguing on the second cradle of the obstacle. He ultimately went the second farthest out of every competitor participating in the tournament. He also was the first to beat Ninja Warrior UK's Crazy Cliffhanger.

Ninja Warrior UK 5
Deren also competed in Ninja Warrior UK 5 - but nearly fell on the Floating Steps and took two attempts to clear the Warped Wall. In the semi-finals, he completed the course in 3:06 - he was just 7 milliseconds ahead of Matt Varela-Christie. In stage 1, he cleared with 1 minute and 52 seconds left. In stage 2, he cleared with 27 seconds left. In stage 3, he seemed to have a solid grip on the fifth ledge on the Crazy Cliffhanger, but shockingly lost his grip with his left hand and let go completely from the momentium and failed.

SASUKE Vietnam 5
Deren had the first SASUKE tournament with SASUKE Vietnam 5. He he cleared the Stage 1A with 113.10 seconds left, but that wasn't enough to get the "Run of the Night" award. But in Stage Two, he shockingly failed the Rope Swing part of Salmon Ladder, when he couldn't transit to the first rope.

American Ninja Warrior 13
Deren was originally slated to return in ANW 12 for his second ANW competion. However, he was unable to due to the postponement of the season from the ongoing COVID-19 pandemic.

Likely to make up for this, he was able to participate in the 2021 ANW 13 season, competing on American Ninja Warrior for the first time in four years. He participated in the second episode of qualifying, where his run was all cut, but he made it to the fifth obstacle, V Formation, before failing. This was enough for him to advance to the semifinals as he placed 24th in the leaderboard. In the city finals, he put up a good run and made it all the way to Split Decision and chose Tuning Forks, but failed it. Fortunately, his time was good enough to place him 6th and advance to the national finals this time around.

In the national finals, his run was digested, but it was shown that he failed Tire Run, ending his sophomore season.
