|“||The name's O'Doherty. Chase O'Doherty. Yes, Chase, not Chasity, is here. And I'm queer. You have a lot to fear.||”|
— Chase upon being exposed to the team
In the middle of "The Reappearing", it became apparent that Chase was actually Gao. Gao speaks in a deep voice, has red eyes, and makes Chase go mad. Gao would've remained inside of Chase for the remainder of the season, but then the rest of the team, save Kaz the fireball and Adam the blind, went back in time to save him. This resulted in an epic adventure, where Oliver, Bree, Angus, Olive, Chyna, Douglas, Fletcher, and Skylar tried to keep their history on track. Unfortunately, this caused serious consequences, such as Adam's virus expanding to all the other academy students, aside from Taylor, Bob, and Spin.When they returned to the present, they found an alternate universe, where Kaz and Chase are hiding out from Gao-Ricardo, and his evil army of Krane-infected academy students. Fortunately, they went back in time to fix this, but a major error propelled them to the first world war. After a bizarre time there, they discovered Chase was alright in the present, as were the students, but Chase announced he was quitting after they told him how they had to keep Gao-Ricardo alive, so he wouldn't possess him. Chase decided to get a new superpower: Possession Immunity to make sure this didn't happen again.

Chase becomes main again, living in his own house with Tina and Berry. He took over for Douglas as Adult Back-up for the team, as well as Academy HOH and Team Supervisor/ Head-Mission Trainer. He and Maya get along wonderfully. In 2051, Chase became Chasity. "She" died of a heart attack in 2060, according to Good Luck, Liv and Maddie's Kickin' Suite Time Wizard ANT World Bunkin' Force: Bionic Superhero Secret Service Division, but remained as a spirit guide for Berry and passed "her" bionics on to Brandon Frangipani. However, with the exposition of his crimes of cross-dressing and conning, the team had to force Chase's bionics out to be given to Brandon.
