Given that Riddler and Two Face are partners in crime in Batman Forever, it makes sense that Kenner made a double pack of figures.
These are basically just repaints of existing figures. The Riddler has a new head sculpt but other than that they aren't any different.
Two Face comes with a gold gun accessory that annoyingly my one is missing. It's based on the gun he uses to blow up the gas line and bury Batman in the subway.
These are definitely good value and perfect if you just want the most movie accurate versions of the two villains.
