The Riddler vs Real World Law Enforcement.
The Riddler is transported to our world. He gets:
- $2 million;
- three solid legal identities with no criminal record (requires some disguise skill to slip between identities);
- standard equipment;
- composite feats of both post-crisis and current version.
He begins a crime spree, always preceded by first presenting riddles related to what he's going to do.
Without Batman or other fictional super-detectives to outwit him, how do things go?
