The series focuses on a team of crime-fighting teenaged superheroes, consisting of the leader Robin, foreign alien princess Starfire, green shapeshifter Beast Boy, the dark sorceress Raven, and the technological genius Cyborg.

The season focuses on a new character, Terra, a hero possessing the ability to move the earth while struggling to accept her boundaries and the Titans as her friends, with Slade's looming presence in her life making it all the more difficult.

The episodes for the season were written by a team of writers, which included Adam Beechen, Rick Copp, Rob Hoegee, Dwayne McDuffie, David Slack, and Amy Wolfram.

Scott Menville, Hynden Walch, Greg Cipes, Tara Strong, and Khary Payton reprise their roles in the second season as their respective Teen Titans - Robin, Starfire, Beast Boy, Raven, and Cyborg.

In addition to her role as Raven, Strong voices the character Kitten, the daughter of Killer Moth, in the episode "Date with Destiny".

Season two also debuts Terra, a young teenage girl with the ability to move the earth around her, and who later develops a relationship with Beast Boy in her second stint with the team, with actress Ashley Johnson providing her voice.

Dee Bradley Baker returns to the series, providing voices for several characters, including the Alien Dog and villain Soto in "Every Dog Has His Day"; Plasmus in two episodes; Overload in part one of the season finale; and Larry, Robin's double from another dimension, in the episode "Fractured".

[5] Film actor Thomas Haden Church provided the voice of Killer Moth, a villain who breeds an insect army, in the episode "Date with Destiny".

[11] Mac McEntire of DVD Verdict praised the Terra story arc as "expertly played" and further commended the series' more dramatic moments, including the mud fight between Tara and Raven, Beast Boy's late-night date with Terra and Robin's last-ditch effort to sway her for good, but remained critical of the comedic aspect of the series, noting that the "two key elements of the series—the action and the comedy—were often at odds with each other".

[12] Starfire is trying to commemorate the Tamaranian holiday Blorthog, a festival of friendship, but is disheartened at the team's constant bickering instead of listening to her.

Though a seemingly great addition to the team, she confides in Beast Boy that she has trouble controlling her powers, and Robin feels off about her.

Despite repeatedly denying her fear, she realizes she truly is scared and rises to fight back, regaining her powers and defeating the monsters.

She awakens to find the Titans safe and learns that she caused the monsters to appear due to repressing her fear.

A villain named Killer Moth breeds an army of insects and unleashes them on the town, but he promises not to destroy the city if Robin takes his daughter Kitten to her junior prom.

Cyborg, Raven and Beast Boy scope out Killer Moth's lair, while a jealous Starfire attends the prom to stay close to Robin.

Initially struggling to get along with one another, Terra and Raven work together to save the Tower; as a result, the Titans accept her into the team, as she has earned their trust.

Robin, Beast Boy, and Cyborg are summoned by the Master of Games to compete in a "Tournament of Champions" against other superheroes such as Speedy and Aqualad.
