World Against S - Divine Spark, Part 2 / Captain Atom, Chapter 6
The effects of the Phantom Zone on Nightwing's body have come to a head. His body has prematurely aged into that of an old man. With nowhere else on Earth to turn, Thara has taken him to Dr. Hoshi at STAR Labs. However, STAR's leading xenobiologist, Dr. Pillings, is in fact the Kryptonian criminal Jax-Ur, another of Zod's sleeper-agents on Earth. Repairing the damage done to Chris would be the simplest thing of all for him, but in exchange he wants something from the Flamebird. Word has gotten out that Lois is working on a story exposing the military as the true source of the destruction of the Metropolis sewer system, and that the 'Metropolis Three' of Nightwing, Flamebird and Supergirl were framed. General Lane has sent a team to the Daily Planet to bring in his wayward daughter.
