Batman & Scooby-Doo Mysteries #12
In our time-twisting final issue, Mystery Inc. meets Batman Beyond! Can the retired Batman and his protege, Terry McGinnis, send our crime-stoppers back from the future? Maybe, but first they'll have to save Neo-Gotham from the Royal Flush Gang and solve a particularly challenging mystery. (And not just the one about safely parking the Mystery Machine with its very expired plates!)
