Judge Dredd: The Dark Judges

They came from Deadworld – twisted, ungodly versions of Judges, with enough power to destroy the world! Led by the cadaverous super-fiend Judge Death, Judges Fear, Fire & Mortis share a chilling ethos – as only the living can break the law, all life is crime!
The fearsome foursome are intent on bringing their brand of justice to Mega-City One. Only Judge Dredd and Psi-Division's finest telepath Cassandra Anderson can stop them from committing a Mega-City massacre.
These stories also feature in The Complete Case Files 03 and 05, and Judge Anderson The Psi Files Volume 01.
