THE THUNDERMANS: UNDERCOVER

A training accident makes Chloe's powers faulty. Max tries to cure her and gets a misleading positive result, so she goes to a party. But his treatment actually creates brand new powers Chloe can't control, so the twins have to get her out!

Chloe, Jinx, and Booch are designing a school mascot, but Max and Phoebe's feud over their jobs ruins the project. Chloe reads them the riot act, and the twins realize their twin-fighting affects Chloe now that they're guardians.

After Phoebe and Max let Chloe's friends watch a horror movie and eat candy, Jinx and Booch's parents want to meet Chloe's. With Hank and Barb away, Max and Phoebe transform into them to help Chloe. It goes well until the real Hank and Barb show up.

Max bets Phoebe she can't turn off being a superhero and go on a normal date. Chloe helps Phoebe do well on the date, but Max tries to sabotage by crying wolf. Suddenly, a real supervillain emerges and puts Max and Chloe in serious danger.

Cherry visits and Max discovers Phoebe never took her sparkle power away. Phoebe promises to do so and has a girls' night with Cherry while Max hosts Jinx. Colosso gets jealous, and Cherry's powers malfunction, nearly blowing Phoebe's cover.

A new super-fast villain is wreaking havoc in Secret Shores, and Billy is the only hope at tracking her down. After Billy's speed accidentally triggers an avalanche, however, he decides to hang up his cape and retire from being a superhero.

Max and Phoebe attend Parent-Teacher Night, leaving Chloe to have friends over without adult supervision. Jinx finds the Air Lair and believes spies are targeting the school, and his meddling puts Max and Phoebe's school jobs at risk.

Chloe feels smothered by Max and Phoebe, and encourages them to make new friends. However, the twins unwittingly make the same friend, and begin a battle for the ages over her. Chloe's new alone time is interrupted by living room-crashing pelican.

Billy arrives, hopeful that his new sidekick Steve can join the T-Force. Phoebe and Max consider it, but soon discover that his superpower is making marshmallows. After they reject Steve's bid to join the team, he turns evil and vows revenge.

The former protector of Secret Shores arrives at the Thundermans' beach house and reclaims it as his home. Phoebe, Max, and Chloe try to reason with him, but when a protest at the school goes wrong, the former hero proves more harmful than helpful.

After Max is targeted by a mystery prankster at school, he seeks help from Principal Bradford. But Max fails to stop the pranks and quits the mission in embarrassment, prompting Chloe to confess that she was the prankster all along.
