"Ninja" Natalie may be one of the most formidable rookie competitors to join The Challenge. The LA native and professional rock climber gained notoriety on American Ninja Warrior as one of the first women to advance to the Los Angeles Finals. If her physical prowess wasn't enough, Ninja also holds a degree in neuroscience, which she will no doubt use to gain a mental edge on her competition. Though the prize money would be nice, Ninja's true motivation to win comes from her desire to push herself as a competitor. As such an intimidating force, she'll have to see if she can find a partner capable of keeping up with her intensity and athleticism.

After a dominating Rookie season on which she became one of only four competitors to reach the end of the Finals -- but the only one to leave empty-handed -- the former American Ninja Warrior standout is back and looking to join the winner's circle. A daunting athletic specimen with a degree in neuroscience to boot, Ninja managed to shine in both physical and mental aspects of the game. As a fiercely independent competitor, it will be interesting to see how Ninja gets along with a team.
