Captain Man has a new crew of superhero sidekicks Danger Force. Captain Man and Schwoz create a fake school to train the kids to harness their uncontrollable superpowers to fight crime.
The kids are living regular lives after leaving Danger Force, but, when their moms go missing, they have to reunite with Captain Man to find them. They quickly discover that all the moms in Swellview have been kidnapped by a mysterious villain.
As Swellview crumbles around them due to a lack of maternal energy, Danger Force and Captain Man must locate and return the moms to safety before corrupt officials take over the city forever.
Mika and Chapa are determined to prove to Miles, Bose, and Ray that the new kid in school, Buddy Fudgers, is actually Lil' Dynomite, before he successfully completes his plan to get revenge on his nemesis, Captain Man.
Danger Force is hired by Rivalton's Duke Wellington to protect him and his ponytail from his jealous uncle, Archduke Fernando. At first it seems like easy money, until they find out The Archduke has hired Ray and Henry Hart to capture Duke.
In an effort to help Mika defeat her rival in a riff-off, Miles sells his soul to a suave demon living in The Man's Nest Abyss Room. Captain Man must soon face the demon in a Ukulele-Log-Rolling competition in order to get all the kids' souls back.
Chapa, Miles, Mika, and Bose are thrilled to have landed dates for the once-every-twenty-years SwellMelonFest until threats come in prompting Ray to make them work security. The threats become a reality when the kids must fight The Cell at the event.
Danger Force sets out to save kidnapped Schwoz; with assist from a familiar Swellview villain, the kids try to take out an evil collective along.
In an effort to hinder Danger Force's performance, The Cell manipulates Jeff and Mitch Bilsky into buying Swellview Jr. High. When Mika, Miles, and Chapa become too dimwitted to fight crime, it's up to Bose to save his friends from Mitch School.
The kids stumble upon a door they have never seen before in the Man's Nest and are determined to see what's behind it despite Ray telling them it's off limits. However, once they get inside, they must deal with the dangerous and bizarre consequences.
When the kids throw Bose a surprise birthday party, his stepsister, Poopsie, threatens to shut the party down unless AWOL is present. Miles is forced to juggle between spending time with his date and keeping Poopsie entertained as AWOL.
Ray breaks up with Credenza, giving Danger Force only 48 hours to teach Ray how to forgive before his relationship is over forever. If Ray wants a future with Credenza, he must confront his past and learn to forgive his greatest enemy, Drex.
Ray retires from fighting crime, leaving Danger Force to face their biggest threat to date; a comet monster coming to Swellview to slay a hero and take over the world with its followers, The Cell! The kids must rise up and defeat it on their own.
Danger Force must fulfill a new Prophecy that they etched into the cave wall; four heroes defeating a powerful monster. To achieve this, they inject themselves with Mom Energy to boost their powers, as Big Dark Dynomite wreaks havoc in Swellview.
