Agent Johnson is the supporting character turned antagonist of Disney Channel's K.C. Undercover. Towards the series finale, Johnson reveals his true colors of him being "The Mask". Johnson was an ally of most of the series. He was a higher-up agent in the Organization and was the Cooper's handler. He informs them of their missions. However, after Beverly was promoted to head of the Organization, he began to show jealousy and hatred towards her. He was successful to take down other enemy agents and take their operations.
Johnson was portrayed by Rick Hall.
Throughout the series, Johnson was an ally to the Cooper family, informing them about their missions. He appointed Ernie a spy after his first failed mission, which he got angry at K.C.
Capturing the Head of the Other Side
During the Abby and Erica situation, Johnson questions Kira on the whereabouts of Erica, her sister. Kira scolded Johnson that she has no idea where Erica is. However, he placed hearing bugs in objects in the Cooper's house, such as Kira's purse, to figure out where Erica is hiding. During election night in Washington, D.C., Johnson continued to monitor the situation. After the attempted brainwash from a server to the elected president, Craig and Johnson try to find the one who pulled the trigger. They were informed by the same guy and they were sent a wild goose chase. Johnson was able to identify who was the head of the Other Side with surveillance footage. Meanwhile, K.C. and Kira seemingly eliminated Abby and Erica but they survived the explosion on the Potomac River and were aided by Richard.
After finding out that Abby and Erica are alive and they captured the Cooper family, Agent Johnson informs K.C. not to negotiate with the Other Side. If she insisted on releasing Abby, she would be kicked out of the Organization. Despite Johnson's warning, she goes on ahead and releases Abby. K.C. drives to the location where Erica and Richard are holding the Coopers hostage. The Organization's helicopter pursued K.C and Abby and Johnson questions why she was going in the wrong direction. Johnson tells K.C that her status as a spy in the Organization is terminated and she was almost arrested but fought back. As Johnson gets up, K.C steals the helicopter and apologizes to him.
K.C enters the Organization with her status terminated. Johnson and other agents pull out their weapons and tell one agent to cuff her. But, K.C stopped them trying to arrest her by capturing Abby, Erica, and Richard (head of the Other Side), and gave them a dozen of donuts. Johnson tells the agents to take them to their jail cells.
After fellow agent Beverly was promoted to head of the Organization, Johnson grew jealous as he felt that promotion should have been his. He decided to send weapons to evil organizations and went under the name "The Mask". He eventually recruited the Bishops to hold the weapons at their home.
When the Coopers discovered the Bishops were spies, they learned about The Mask but did not know who it was until capturing Mitch Bishop and Danielle Bishop. That is until they realized Amy Bishop is the Mask.
K.C and Ernie chase Amy up a lighthouse. Once they were done fighting Amy, she was dangling off the lighthouse K.C grabs hold of her and ask her about who is The Mask. She told K.C that someone very close to them was The Mask. She lets go of K.C and falls into the water. Before she fell, Amy had dropped the Necklace containing the information of all the evil organizations' leaders which The Mask was supplying too.
As "The Mask"
They soon told Agent Johnson about The Mask being someone they know and thinking they could trust him. Once there plan to capture all the leaders of the evil organizations was a success. Once everyone at the organization was celebrating the end of the spy war, The Mask ( in a dark room with a disguise translate to hide his identity) revealed this was his plan all along to have all the leaders be captured so he could take over there operations.
Once Judy wanted to be resigned to anther spy family, Johnson called Judy to his office, where he reprogrammed and told her to eliminate the Coopers. Enemy agent turn agent Brandy overhead this and had quickly called KC to warn her but was stopped by Johnson and Judy who injured him and was sent to the Hospital. Johnson later went it the Coopers and told them that Brady was The Mask. But he told Judy that they still needed to be enlightenment. After Judy failed to kill KC and the family and was a return to normal. Marisa who had gone to see Brady believing that he wasn't the mole and found out by Brady that Johnson was the Mask and told the Coppers.

After everyone left the room, the two spies it is revealed that the two spies work for Johnson and they free him and revealed he planned on going to K.C. graduation.
As soon as K.C began her speech, Johnson and his two agents barged in the auditorium, with the Cooper family in utter disbelief. Judy tried to fight them but was locked out. Johnson told K.C that she took everything from him and pay the price. He shoots his gun in the air, telling everyone not to move and points his gun at K.C. The Cooper family and Johnson engage in combat. K.C defeats Johnson and his two agents.
Johnson is a ruthless, egotistical, and a senseless agent to the Organization. Since he's the Cooper's handler, he acts aggressively towards them, especially K.C. When he wants something done, he would be tempered to have it completed, such as finding Erica. In the wake of Zane Willis' rise from the woods, he showed some sympathy to the Coopers when their helicopter crashed in the ocean.
Johnson is a middle-aged man who always wears a suit and a black tie. He once dyed his hair completely black but it was a mistake, leaving a gray spot on the back of his head.
- Although he's a recurring character, Johnson shows signs of aggressive behavior that is nearly equivalent to a villain until it was clarified in the series finale.
- However, he did show some villainous behavior when he was monitoring the whole of Abby and Erica's situation by planting bugs in the Cooper house.
- It is unknown if Johnson manipulated the Cooper family throughout the series.
