Author's Note: As the summary suggests, this is a crossover story between "The Real Adventures of Jonny Quest" and "Batman: The Animated Series," two very popular (and awesome) cartoons of the 1990s.

Prologue

Someone new was crawling around in the city. His city. He thought it started last autumn, but he couldn't be sure. Whoever it was wanted to stay underground, and was good at doing so. There weren't any new turf wars lighting up the night. No maniacal announcements into greedy news cameras. Not even rumors whispered among the foot soldiers of crime, looking for work. Someone was lurking in his city, nurturing deep, unseen connections in Gotham's underworld. He didn't like that at all.

Unfortunately, what he thought might be a good lead turned out to be a dead end. Batman opened his fist and let the miscreant's body fall limply to the wet pavement. When a policeman's searchlight flashed down the alley seconds later, it had only one occupant, and he wasn't going anywhere fast.
