Kole is the 58th episode of Teen Titans and the 6th episode of Season 5.
The Teen Titans face off against a new and improved Dr. Light at a polar ice cap, and fall under the ice to a land that resembles the earth when dinosaurs reigned. While fighting Utahraptors, the Titans are saved by Kole, a girl who can turn into crystal, and Gnarrk, a Neanderthal. The pair easily defeats the dinosaurs and invites the Titans to their home. Cyborg beats Gnarrk in an eating contest, and thinking that Kole will like Cyborg better than him because of this, Gnarrk leaves. Kole goes to him and tells him he will always be her best friend. Then they are attacked by Dr. Light, who wants to use Kole's power to create a power beam. Dr. Light escapes with Kole, and the Titans and Gnarrk set out on an expedition to rescue her. During their trek, Gnarrk shows his excellent tracking skills. They confront Dr. Light and his machine, where Gnarrk has to choose between his best friend or his technophobia. After several failed attempts, Cyborg throws a wrench to Gnarrk and he manages to disable the machine. After defeating Dr. Light, Robin gives Kole a Titans Communicator and tells Kole and Gnarrk to call them if they need help. The episode ends with the Brain and the Brotherhood of Evil locating Kole through her communicator.
- This is the only episode in which Dr. Light did confront Raven and isn't scared of her.
- When they first confront Dr. Light, Starfire is the only Titan not to be wearing winter gear, implying that Tamaranean skin is immune to Arctic cold. This was also proven in the previous episode Snowblind. However, in How Long is Forever?, she is shown being cold in the future.
- This is the second time where Beast Boy transforms into a Megatherium. The first time was in Titan Rising.
- The prehistoric animals in the underground world include a herd of Parasaurolophus, a Pteranodon, and a pack of Utahraptors.
- Similar to The End, Part III the scene where Beast Boy uses a Tyrannosaurus form to battle Utahraptors parodies Jurassic Park. The scene where he battles many Utahraptors is an allusion to the ending of the first Jurassic Park film.
- The underground world may have been inspired by the Jules Verne novel Journey to the Center of the Earth, though there are other examples of such worlds, such as Skartaris which features in DC comics' Warlord and the Justice League Unlimited episode Chaos at the Earth's Core.
- When Gnarrk tries to release Kole using Cyborg's spanner he starts by turning the screw anti-clockwise, which should actually tighten the screw rather then loosen it. This was probably in order to show the caveman's unfamiliarity with such tools and why he eventually resorts to brute force in order to release Kole.
- Robin: Your machine can't take any more!
Dr. Light: Illuminating theory - but I have the definite advantage!
[At that exact moment, his synthetic diamond disintegrates]
Dr. Light: Or not.
- Cyborg: He should have landed somewhere over... Oh boy!
[A pack of red Utahraptors corner the Titans]
- Starfire: Beast Boy, perhaps you can communicate with them.
Beast Boy: [timidly] Um ... nice dinos?
Raven: Hey, genius, I think she means try it in their language.
[Beast Boy turns into a raptor, exchanges a few yips and hoots with them and then returns]
Robin: What did they say?
Beast Boy: Well, they want to eat us.
- Kole: Sorry, Gnarrk's not so good with people from the upper world.
Beast Boy: Neither is Raven.
[Raven looks menacingly at Beast Boy and Starfire laughs]
- Kole: So what brought you here?
Beast Boy: Er ... Gravity?
- [After Dr. Light has been defeated]
Raven: You're a sad little man, aren't you?
