Titans, Vol. 1 #24A

Who is Troia?, Second Chances
The Kingdom Titans, of Earth-22, battle Dark Angel to save Donna Troy, whom no one remembers. This fight draws the attention of the Titans, who mistakenly conclude that the woman they don't know went for help and has returned to attack them! There's a fight, ended by the timely intervention of a still recovering Arsenal. Finally, the two teams talk. The Earth-22 Titans provide a version of the story, and allow the Titans to assume they are a rival, government created group. This, because they can't know the truth about hypertime. Or so says their real sponsor, Zeus himself! Zeus is most interested in preventing Dark Angel's scheme, as this would destroy Donna in all worlds. The Earth-22 Titans explain that they must find Dark Angel in her lair before she can recharge, and to get there they need Tempest to open a portal. During these conversations, the Titans all begin to realize that the Earth-22 Titans are familiar. As they should be: most of them are the sons and daughters of the Titans Earth-22 counterparts!
