Wait--but WE'RE the Teen Titans!
What happens when the Teen Titans suddenly end up in the future? Nineteen years in the future, to be precise. The Titans end up next to a crime taking place. But before Robin can say," Titans, Go!" Someone else does. The villain is caught by some group calling themselves the Teen Titans. So, they follow them. But our heroes soon find out that these so-called Teen Titans aren't impersonators; It's their own children!
