Teen Titans (season 2)

Starfire is trying to commemorate the Tamaranian holiday Blorthog, a festival of friendship, but is disheartened at the sight of the rest of the team's constant fighting. When Warp, a villain from the future, comes back in time to steal an antique, Starfire follows Warp as he prepares to jump through time, arriving 20 years into the future. She searches for the Titans for help, but finds the team broken up. She attempts to rally the Titans together to take down Warp and return back to her time.

A lonely Beast Boy goes into the city as a green dog when the rest of the team is too busy for him. He gets captured by a spaceship and played with by the alien Soto, who believes him to be his original dog. Meanwhile, the other Titans have noticed Beast Boy has gone missing, and end up chasing Soto's dog, believing it's their teammate.

The Titans meet Terra, a girl with the power to move the Earth around her, and invite her to stay with the Titans, much to Beast Boy's delight. A seemingly great addition to the team, Terra later confesses to Beast Boy about her inability to control her powers. While on a mission with the Titans, Terra is confronted by Slade, who knows her secret and taunts her with it. Terra later leaves after the rest of the Titans learn her secret.

When Cyborg beats Atlas, a self-proclaimed full robot, in an online video game, he challenges Cyborg to a real, physical fight. Due to the limits on his strength while Atlas has none, Cyborg loses to Atlas. Atlas then kidnaps Robin, Starfire, Raven, and Beast Boy as his prize and challenges Cyborg to a rematch where his friends' lives are at stake.

The Titans defeat Control Freak at a video store and receive a scary movie free as reward. After watching the movie, the Titans are awakened by screams and find the tower under siege by mysterious monsters similar to those in the movie, with Raven unable to use her powers. One by one the Titans are taken out, with Raven left to fight the monsters alone. Despite denying her fear at first, she accepts it and regains control over her powers, vanquishing the monsters in the process. She awakens to learn that the monsters accidentally came from her powers as a result of her denial of fear.

A new villain named Killer Moth breeds an army of insects and unleashes them on the town. However, he promises not to destroy the city only if Robin will take his daughter Kitten to her prom at a party cruise. Cyborg, Raven and Beast Boy scope out Killer Moth's lair, while a jealous Starfire attends the prom to keep a close eye on Robin.

Note: This Episode aired before Transformation, but Starfire still shot energy from her eyes. This was most likely due to this episode being completed sooner.

Starfire wakes up to discover a huge forehead lump on her forehead, which leads to tusks on her neck, elongated zebra-coloured fingernails, weird cravings for unusual food, pointed ears, large hairy feet and scale-like skin. Believing she is turning into a monster, she leaves and takes refuge on a planet deep into space. She meets a charming, kindhearted alien who dispels her fears. After she becomes encased in a chrysalis, the alien turns out to be a Tamaranian chrysalis eater. Meanwhile, the rest of the Titans search the galaxy for her, eventually finding the planet and rescuing a refreshed Starfire from peril while the Cironielian Chrysalis Eater is defeated.

Note: As of this episode, Starfire develops the additional ability to emit her bright green-colored ultraviolet energy from her eyes, as her elder sister can, though her heat vision is much thicker.

Terra is back, having mastered her powers while she's been away she says she is now ready to become a Teen Titan. The others still aren't so sure she is ready after what happened the last time they saw her, they decide to let her prove herself and not a moment to soon. Slade is back and his new worm like robots are causing earthquakes around the city, the Titans go to investigate the happenings underground and during the mission Terra and Raven must learn to work together if they want to stop Slade and save Titans Tower.

Robin, Beast Boy and Cyborg are summoned by the Master of Games to compete in a "Contest of Champions" against other super powered males. Everyone invited is willing to participate, but Cyborg becomes suspicious when he sees losing contestants vanishing.

Terra and Beast Boy go out on a date during the night while the tower is under siege by Slade's minions. Slade then interrupts the date and shows Beast Boy where Terra's loyalties lie.

Robin is bothered by Larry, his double from a different dimension, who appears after Robin breaks his arm. While wrestling with Larry, Robin breaks Larry's magical finger, causing the city to become distorted. Villain Johnny Rancid takes advantage of the chaos and transforms himself into a darker version of himself.

Slade sends a newly-transformed Terra to attack the Teen Titans. Unable to defeat her, the Titans retreat and regroup, planning to break Slade's grip on Terra. Terra frees Cinderblock, Overload and Plasmus from prison and, through Slade, disperses them throughout the city to take down the Titans. This turns out to be a decoy to bring the Titans out of hiding and destroy them one by one.

With the Titans seemingly gone, Slade has taken control of the city, but the Titans don't go down so easily. They unleash payback on Terra for betraying them to join Slade, which leaves her feeling broken inside more than ever before. Regretting every action since her betrayal, she begs Beast Boy to finish her off before Slade takes control of the situation and causes a horrific and saddening fate that leads to his own demise. In the end, Terra sadly sacrifices herself to save the city and the Teen Titans as the Titans mourn their good friend, even Beast Boy.
