The Rube Goldberg contrivance (usually not so much a device as an unnecessarily convoluted plan to accomplish a simple task) is generally how they arrange to catch the villain. The plan usually goes wrong in some way, but ends up succeeding regardless due to dumb luck. Then they take the villain’s mask off, and explain the clues that allowed them to know who was underneath in advance.
Once they’ve worked out that all the supernatural menaces are actually human charlatans, they could deal with nearly all of them (those which aren’t some sort of device operated remotely) simply by catching them and taking their masks off, thereby circumventing the need to figure out who’s inside beforehand.
