Bree and Chase meet up with Kaz, Oliver, and Skylar where they meet two shapeshifters, Roman and Riker who destroyed Mighty Med and are on a mission to destroy the Elite Force now.
In an effort to win over Skylar, Oliver elicits Chase's help in recovering her powers. Meanwhile, Kaz offers to pet-sit a neighbor's pig, much to Bree's chagrin.
Oliver takes Skylar to see her superhero friend, Crossbow, unknowingly leading to Roman. Chase and Bree capture Riker after he tries to retrieve the complete list of superhero identities and locations from Mission Command.
Kaz is eager to brag about his powers to his little brother Kyle, but can't due to the "Superhero Code." Meanwhile, Bree accuses Oliver of using his powers to damage her belongings.
Roman and Riker's black swarm returns, so the Elite Force hops into action to protect Centium City. There's more than meets the eye with Chase's new girlfriend Reese.
Known as the fastest girl in the world, Bree is offered a sneaker line...until Skylar unveils her own super speed. Meanwhile, the guys compete to design the best mission suit.
When Oliver skips out on their tradition of pulling Halloween pranks in favor of a date with Skylar, Kaz continues on his own. Meanwhile, Perry enlists Bree's protection for the night.
After Skylar fills in as mission leader, Chase sets out to prove that he is the only team member equipped for the role. Perry moves into mission command.
