Kacy Catanzaro (ケイシー・カタンツァーロ) is an obstacle course trainer, former NCAA gymnast, and ex-girlfriend of Brent Steffensen who competed in American Ninja Warrior 5. She and Steffensen train together at obstacle course gyms having practiced on obstacles like the Jumping Spider, Salmon Ladder, Ultimate Cliffhanger, and the Warped Wall.

American Ninja Warrior 5

Catanzaro made her debut appearance in American Ninja Warrior 5, at the Venice qualifying course. She easily cleared the first three obstacles but took a lot of time on the Floating Chains due to her height. As a result, her hands got tired and she wasn't able to grip onto the Flying Nunchucks. Along with Steffensen, they both competed at the Vegas Finals as wildcards. On her run, she beat the Timbers easily but on the Giant Cycle, her feet hit the edge of the trampoline causing her to fall into the water.

In American Ninja Warrior 6, she passed all 5 obstacles and became the third woman after Nika Muckelroy and Jessie Graff to make it to the Warped Wall. Unlike Nika and Jessie, she was able to complete the obstacle and became the first woman in American Ninja Warrior history to complete the qualifying course, and the third to qualify for the city finals, finishing in 21st place. At the Dallas City Finals, she went on to become the first female to ever to earn her spot at the Vegas Finals by completing the city finals. In the Vegas Finals, she got her revenge on the Giant Cycle but tragically failed to stick the Jumping Spider.

American Ninja Warrior 7

After gaining a large fan base due to her success in the previous tournament, she vowed to repeat on American Ninja Warrior 7. However, in the Houston qualifier, she failed the Cargo Crossing while trying to leap to the bar. Despite this, she received a Wild Card spot to the Las Vegas finals. In the Vegas finals, a nervous Kacy wanted to redeem herself after her dramatic failure in the Houston qualifiers. On the course, Kacy managed to complete Piston Road with ease but just like two years ago, she overshot her jump on the mini-trampoline to the Propeller Bar and fell in the water. She was shown crying in a post-run interview, saying that she was not going to fail an American Ninja Warrior obstacle course.

American Ninja Warrior 8

She competed again in American Ninja Warrior 8 in Oklahoma City, hoping to redeem herself after last year's disappointment. Catanzaro passed through the first two obstacles, but her size proved to be a disadvantage on the Log Runner, due to the distance between each log was 4 feet, almost 80% of her total height. Consequently, she tripped on the fourth log. She attempted to recover, but the log ended up spinning, thus causing her feet to hit the water. Kacy received a Wild Card spot in Vegas for the second year in a row. However, she failed on the Propeller Bar again for a second straight season despite landing on the trampoline properly.

American Ninja Warrior 9

In American Ninja Warrior 9, Kacy had high ambitions to redeem herself after falling in qualifying the past two seasons. It was shown that Kacy had even higher stakes this season particularly due to her mother's heart attack recently. Kacy completed the first three obstacles easily, which secured her spot in the finals as one of the top 5 women. However, she made a fatal mistake on the Sky Hooks when she attempted to make the last swing, only for the ring to get stuck from the hook. Though her performance overall wasn't in the Top 30, she went the 2nd farthest out of all the females in San Antonio, advancing her to the city finals.

In the city finals, Kacy avenged herself on the Sky Hooks and even defeated the following obstacle, the Pipe Fitter. Unfortunately, she wasn't able to scale the adjusted 14'6 Warped Wall on her three attempts. Even though she failed, she still earned her ticket to Vegas by finishing in the top two of female competitors. On August 28th, 2017, it was announced that Kacy will be retiring from American Ninja Warrior and signed a contract with the WWE as a wrestler. In Kacy's final run at Mt. Midoryama, Kacy finally managed to defeat the Propeller Bar that eliminated her in the past two seasons. Her run was short lived though, as she failed the very next obstacle, the Double Dipper, when she failed to grab the second bar.

Kacy competed in SASUKE 32, as the 51st competitor to run the course. She passed the first two obstacles with ease, managed to quickly get her traction on the TIE Fighter and easily passed the other obstacles until she reached the Soritatsu Kabe with 40 seconds left. She ended up losing a great deal of time on the Soritatsu Kabe due to the physical exhaustion following the Tackle and thus timed out at the Lumberjack Climb, having attempted it with 4 seconds left. By making it to Lumberjack Climb, she made further than any women in that tournament.
