Jonathan Kent isn't a Teen Titan. He's just a kid, and one of the most powerful beings on the planet. But what if he has the potential to hurt people without even meaning to? That's exactly what Tim Drake says will happen. But this isn't the Tim Drake of today -- this is the Batman of Tomorrow, and he's traveled through time to kill Superboy. He tells the Teen Titans that if he succeeds in killing Superboy, he will save the millions of people that Superboy will kill in the future. The Teen Titans have split in half over how to handle Superboy and don't know whether to trust him or Drake. So, Superboy's closest friend, Damian Wayne--the current Robin and leader of the Teen Titans--has Jon on the run from Drake ... and from his own team.
