Gail Simone, John Byrne and Nelson DeCastro take over as the creative team with Action 827 (July 2005).
Aura, from the short-lived team Superboy and the Ravers, makes a brief appearance, an early victim of Repulse, who forces Aura to use her own powers to pull a helicopter down onto her.
Superman encounters Dr. Polaris first, and thinks he is behind the magnetic manipulations taking place. But Polaris is on the run from Repulse.
Superman can tell that Repulse is not really there, she is just an illusion. From his earliest appearance, Dr. Polaris suffered from a split personality, and that is clearly what is going on here, with Repulse his latest manifestation.
The story continues in the next issue.
