Undercover Rangers is the thirty-first episode of Power Rangers Time Force.
The Power Rangers go undercover at a gym to discover that Frax is using it as a front to turn its customers into robots. With help from Eric, the team must defeat the mutant running the gym, and rescue the customers.
Katie and Trip spot a man promoting a protein drink, which makes a scrawny guy from the audience super strong. At the clock tower, Jen and Wes try to build up the courage to ask each other out, but it ain't happening. Katie and Trip arrive with the news. Jen and Wes are cajoled by Lucas to go undercover at the Super Strength Gym to investigate. Jen and Wes enter the gym as a couple of hillbillies looking to work out. Jen gets jealous when Wes flirts with the girl at the front desk. Jen snoops around, and discovers that the customers drinking the protein drink are being turned into robots. She is found out, and captured, Frax reveals himself and tries to force her to drink the robot juice. Wes encounters one of the burly guards, who turns into a Cyclobot and attacks him. He makes it to Jen just in time to save her from being turned into a robot. He frees her and they make a run for it. Outside, they are stopped by a squad of Cyclobots. Eric shows up and holds them off. Jen tries to make Wes jealous by fawning all over Eric. Jen, Wes and Eric morph, but the monster levitates them and slams them into each other. Trip, Lucas and Katie arrive and save their teammates by blasting the mutant with their V Weapons. When even six Rangers can't defeat the mutant, Circuit calls on Alex for help. Alex contacts Wes, and tells him that he is sending him the Strata Cycle, and asks him to protect Jen. The Strata Cycle is launched through the time gate, and Wes boards it. Things don't look good, as the mutant grabs Jen in a strangle hold Jen pulls away in time for Wes to zip by and knock him out. But he's not out yet, as the mutant grows into a giant. The Zords are called, and the mutant does his levitation thing again to make Q-Rex slam into Shadow Force. The Zords get their bearings and put a finishing move on the mutant. Jen and Wes resume their struggle to reveal their feelings for each other. But they are interrupted when the scrawny guy shows up looking for a personal trainer. Trip, Lucas and Katie say that Wes and Jen would love to help, but they quickly deny and the episode ends with them arguing about it.
