DC One Million #2A (1998)

One Million - The Day After Tomorrow
The true combination of threats stands revealed: with Starman's help, Solaris infiltrated Hourman in the future, and loaded him with a virus that attacks both flesh and machine in the 20th Century. Ray Palmer checks it out within Oracle in hopes for a cure, while the JLA teams from both eras join forces to stop the missiles of Vandal Savage, not knowing that the missiles are armours which contain captured Teen Titans.
