Lance takes up being a vigilante and an intelligent roach-like Muddradi assassin comes after the princess. Lance's exploits are on the news without people knowing it was him, and Octus warns Lance not to take Earth laws into his own hands.

The group must protect their fellow classmates without the aid of Sym-Bionic Titan when a huge tar creature manages to infiltrate Sherman High School and traps everyone inside the building.

Kimmy, the head cheerleader, forces Octus (as Newton) to tutor her after she fails a test, where things take an unexpected turn of events. Meanwhile, a Mutradi monster lands in the city where Lance and Ilana come across it but are unable to activate their mech suits.

An annual party celebrating a local legend gets interrupted by a shape shifting alien.

Meanwhile Newton continues to explore his relationship with Kimmy.

Ilana is homesick, so she joins the Homecoming Dance Committee and creates a Galalunian-themed dance. Meanwhile, General Modula's continued failure to kill the princess is spreading across the galaxy. Modula is approached by an alien who guarantees on his own life that he has a creature that will kill Ilana and crush the Galalunian People's spirit. As our three heroes try to prepare for the dance, Lance and Kristin go a little further in their relationship via a karate bout, but she declines his request to join him at the dance. Issues arise when the Mutraddi arrives just as they depart for the dance. Titan at first fares poorly, as Octus and Ilana are distracted by missing the dance, and making Kimmy cry. However, Lance's lack of concern for their feelings pushes Ilana over the top, and the alien is soundly defeated.

General Steel unleashes his newest dastardly creation in the form of his own giant killer robot, and faces the team of heroes to scramble in order to find a way to defend themselves and the planet without the aid of Octus.
