Gotham City

On a simple trip to pick up groceries, ShadowStar in her civilian identity of Tina Grewal gets taken hostage by the Joker, who needs bait to draw in the current Robin. Joker was not the sort of villain to look around for witnesses; he has no idea that someone witnessed the crime, and is willing to pursue Tina's captors wherever they may go.

Each following their own trail of stolen items transported across the northeastern U.S., Dr. Doom and Wyldfire agents travel from a Metropolis warehouse to a corporate laboratory in Gotham City, then back to a villain lair in Metropolis where the combined villainy of explosive metahuman Plastique and body-controller Shimmer have chosen to become a single person named Muse.

And to grow themself, in true Rocky Horror fashion, a perfect boyfriend.

Who is going to look a lot like the young Hero of Metropolis known as Silverwing.

Vivisected bodies washing up on the Lackawanna River, the kidnapping of a mercenary team, and a theft of organ transplant anti-rejection medicine from Gotham City garners the attention of Batman. He sends Ace into the fray with the Master Thespian (as Humphrey Bogart), Trickshot (as Christopher Lee portraying Van Helsing), and Taki to sort out a web of murder and kidnapping in the name of "science".
