Oliver works to master his superpowers after being outshined by Kaz during superhero training. Meanwhile, when Bree says Skylar is like a sister to her, they work out their new sisterhood. Later, Kaz discovers a new superpower, which enables him to shoot fire out of his mouth and Chase and Davenport are impressed; however, Oliver feels intimidated as he's still struggling with controlling his new superpowers. Meanwhile, Bree is having trouble bonding with Skylar as a sister because on her planet all girls roughhouse with their siblings as a way of having fun and showing love to them. Oliver later discovers a new superpower that he calls cyclone fingers, but when Oliver shows Davenport his new superpower, things go awry and he knocks him off his feet and Davenport is sent flying in the air and goes over the terrace railing. Rather than plummeting to the ground below, Davenport is able to hang off a bust of his head on the side of the skyscraper. Oliver goes to save him, while Kaz and Chase watch him with no backup plan. Oliver hangs from the head for a while, but he eventually saves Davenport. Later, Skylar and Bree finally form a bond in the meantime.

Oliver has always had a major crush on Skylar, and now that Oliver has superpowers, Skylar does not like it because she has lost her superpowers. Chase decides to come up with a solution to give Skylar her superpowers back, but he must inject coal into her body, though it is her one weakness. Oliver gets jealous because he wants to be the one to give Skylar her superpowers back, so Chase decides to let Oliver take the credit despite being reluctant to it. After injecting the cure, Skylar starts to become weak and ill from the coal and is coughing up vapor that can kill everyone in the building. Skylar pulls through and gets her superpowers back and learns that the illness was just a side effect. Meanwhile, Kaz goes behind Bree's back and agrees to babysit Mrs. Ramsey's pig; however, this is all just a scheme for the woman impersonating their neighbor to rob the penthouse. Later, the pig outsmarts both Kaz and Bree and locks them out on the balcony and they then watch Mrs. Ramsey stealing everything until Kaz notices an open window above them and flies back into the penthouse. Chase, Oliver, and Skylar come upstairs and Skylar stops Mrs. Ramsey with her newly restored superpowers.

When Kaz's little brother, Kyle, visits, Kaz becomes jealous that Kyle seems to like Chase more than him, and Kaz cannot reveal his identity as a superhero due to the "superhero code". Chase's controlling attitude gets on Kaz's nerves and Kaz and Kyle explore the unauthorized areas of the base. Kyle ends up trapped after messing with the mainframe computer and Chase attempts to get him out of the cage, but he is knocked out by a shock from the cage. Kaz is forced to reveal his superhero identity and uses his firepower to break the cage open. As Kaz is about to reveal the truth, Kyle thinks they made Kaz bionic, with which he goes along. Oliver and Skylar agree they will also have to pass themselves off as bionic in public so that they can use their superpowers freely.

Douglas comes to see the team and wants to start making the mission suits for them. Chase initially competes with Douglas to make the mission suits for the team and Chase and Kaz work together to make their version of mission suits while Oliver and Douglas work together to make their version of the mission suits. When Kaz and Oliver test out their mission suits, they fail to catch a fly, which proves their suits' impracticality. Chase and Douglas decide to put their differences aside and work together to make the best mission suits for the team. Meanwhile, Bree is filming a shoe commercial and she and Skylar compete in a super speed race. The shoe commercial is not successful as Bree and Skylar end up sabotaging each other in the super speed race.

After Chase is left behind during a mission because Perry shot out the controls of the hyperlift, Skylar steps in as mission leader. However, this makes Chase jealous, and on the next mission, when Skylar is downstairs with Perry, Chase disables the hyperlift. Perry helps Skylar out of headquarters and to the mission site through the underground tunnels that Perry used to break into headquarters. At the mission location, the tunnel becomes unstable and almost collapses on Skylar and Perry, but Chase pushes them out of the way; however, it traps them in the process. Perry tells Skylar that Chase disabled the hyperlift before the mission so that he could be mission leader again and Chase later admits that he feared losing the respect of the entire team. On the other side of the rubble, Kaz manages to make a stable tunnel to where Chase, Skylar, and Perry are trapped and rescues Chase, Skylar, and Perry. Later, when Skylar is asked by the rest of the team as to why she missed the mission, she tells them that the hyperlift malfunctioned again. When Chase asks why she didn't say anything about the incident, she explains it was the exact same way she felt when she lost her superpowers and that she would not wish that to happen to anyone. Perry uses this opportunity to blackmail Chase into getting her a penthouse next door to theirs.

The team receives a box from Davenport with all the gadgets they used back at Mission Creek, which includes the cyber cloak and the memory wipe. Chase hosts a team meeting and compiles a list of all the superheroes from Mighty Med and warns them that Roman and Riker are hunting them down. This includes Skylar's mentor and first friend: Crossbow. Skylar wants to see her again, but Chase refuses because it is too risky. Kaz plays with the Chase and Bree dolls that also came in the package, but they are taken away by Chase over a dispute on what they are actually called. Meanwhile, Skylar is worried that Crossbow did not get the message and she and Oliver set out to find her. When they leave, it's discovered that Roman and Riker had been eavesdropping on them as ravens, and Roman follows them. When Skylar and Oliver get to the park, they find Crossbow working as a groundskeeper. Meanwhile, Riker spies on Kaz who is distracted by listening to music while Skylar and Oliver inform Crossbow that Roman and Riker are hunting all superheroes. As soon as they start to leave, Roman shows up and attacks Crossbow who suffers a tough blow. Back at headquarters, Kaz checks out the cyber desk until Chase and Bree walk in on him looking for the list. When Bree talks about the dolls that Kaz was playing with, he does not remember it as he's not Kaz and transforms into Riker, who was looking for the list. Back at the park, Oliver tries to attack Roman, but he is easily defeated; then Skylar attacks him, but she is defeated as well. As Roman tries to walk away with Crossbow, Riker shows up and informs him that the other superheroes know of their presence. Chase and Bree follow Riker to the park and Roman and Riker try to form their deadly swarm, but it does not work because Riker turns out to be Bree and Bree turns out to be Kaz. Bree informs Roman that Riker is locked in a freezer, causing Roman to make a deal that Crossbow will live in exchange for Riker and the list. Skylar agrees and Bree brings back Riker; however, when Roman tosses the list to Riker, Crossbow destroys it and is defeated in the process. Skylar becomes upset and attacks Roman and Riker and defeats them. Roman and Riker retreat, but Roman warns them that they will be back. Later, Kaz and Oliver are able to revive Crossbow by turning her gloves inside out, which causes them to produce healing energy similar to the equipment that was used back at Mighty Med.

When Oliver's hero is in town, he gets excited and wants to meet him at the Olympics Send-off Celebration at the park. Kaz, Oliver, and Skylar go to meet Clutch while Chase and Bree go to a mini-Olympics competition for children, where they run into Bob. He had signed up for the competition and would win by using his bionic abilities, but Bree convinces him not to cheat. Meanwhile, Oliver, Kaz, and Skylar are waiting for Clutch to arrive; when Clutch arrives, he shows off his skills, impressing Oliver. However, things go wrong when Oliver asks Kaz to hold his sign and Clutch notices Kaz instead and asks Kaz to be his spotter, which causes Oliver to become jealous. Clutch attempts to lift 1,000 pounds, but he quickly starts struggling; when Oliver attempts to help, he drops the weight on Clutch's foot. Meanwhile, Bree discovers that Chase has become Bob's coach and is upset that they are going to cheat. Later, Oliver feels sorry for hurting his hero and Skylar runs to the hospital and abducts Clutch. She brings Clutch back to the penthouse and Skylar pep talks Oliver to fix him with his old Mighty Med supplies. Oliver quickly responds by saying it is not possible, but he will try to help Clutch. Meanwhile, Bree has found a child named Zoe who was originally going to compete in the competition with her dad; however, something had come up and Bree decides to become her new coach, though her plan is also to use her bionics. During the final part of the competition, Chase tells Zoe that Bree does not think Zoe can win by herself and Zoe wants to do it without Bree's help; consequently, Chase agrees he will not help Bob. When Chase sees that Zoe is winning, he cheats and uses his bionics to hold Zoe back, so Bree uses her bionics and pushes Bob back. Chase and Bree start fighting while Bob and Zoe run to the finish line. Bob wins the mini-Olympics competition and Chase feels joyful and grabs the prize out of Bob's hands; however, Bob takes it back and hands it to Zoe as he wants her and her dad to run with the flame. Meanwhile, Oliver finds out a way to fix Clutch and freezes his foot while Kaz heats his foot.

A ten-year-old computer genius boy living on the floor below the Elite Force manages to break in to the penthouse, so Chase improves the security system by installing retina scanners, but the boy manages to get back in because he hacked Chase's chip. He later uses his tablet to make Chase disable the security system. Meanwhile, the others are having a contest to determine who can go longer without using superpowers or bionics and they make two teams: Oliver and Kaz versus Bree and Skylar. Bree uses her super speed when Oliver lies and says he sees Harry Styles from One Direction in front of their building. In retaliation, Bree asks to borrow Oliver's phone and throws it off from the terrace and Oliver uses his flying power to go after it, which gets him disqualified. Bree tries the same thing with Kaz by throwing off many of his valuables, but he resists using his superpowers. Meanwhile, Chase's magnetism app glitches because of what AJ did to his chip and every metal object starts flying toward Chase. As a result, Kaz and Skylar have to put the contest on hold to help Chase. AJ then realizes that Chase's capsule can reset his operating system and fix the glitch and Oliver and Bree quickly bring down his capsule. With Chase rescued, the contest is back on and Bree manages to trick Kaz into using his superpowers by using her cyber cloak to pretend to be Oliver and make him fire up the grill; as a result, the girls win the contest.

AJ reveals that he knows that Kaz, Oliver, and Skylar are superheroes and compiles a list of the team's usefulness, causing hurt feelings with Chase and Bree. Meanwhile, Oliver discovers that Kaz has been keeping the Arcturion in storage, though he wasn't aware of it, and Chase tells Kaz and Oliver to take the Arcturion to Facility Y, which is one of Davenport's storage locations. However, they discover it is missing and suspect AJ who was fascinated by it earlier. Chase kicks AJ out of the penthouse in anger, but the team later realizes that Bree took it because she was jealous of the others. Meanwhile, Bree plans on touching the Arcturion to get more powers, but Skylar blasts the Arcturion before Bree can grab it; however, the blast redirects and hits Bree. Later, Chase is determined to raise his rank and builds a hover bike with AJ in order to get to missions faster; however, when the bike goes missing and it's discovered that AJ has taken it, Chase, Kaz, and Oliver go to his rescue. Meanwhile, Bree grows weak from the Arcturion's blast and Skylar is forced to touch the Arcturion to redirect its healing energy into Bree. However, it comes with a cost because Skylar loses a few of her superpowers. Since Bree made indirect contact with the Arcturion, she gains superpowers known as thermo touch and proton ring generation, which makes Bree the world's first bionic superhero hybrid, and Bree and Skylar agree to keep Bree's new powers a secret for now.
