Cy Platt was an acrobatic performer from San Diego, CA, who competed on American Ninja Warrior 2 alongside his brothers Boone and Cheetah.

In qualifying, Cy showed the cleanest technique out of the three brothers, showing much better speed and technique on obstacles such as the Quad Steps and Spider Jump. However, he slowed down on the Jumping Bars, and as a result, despite eventually clearing, his time was too slow to move on to the semi-finals, placing 33rd overall after being knocked out by Trevor Vaughn. However, he did perform the best out of the three brothers.
