Justice League Communicator
The Justice League Communicator
A more detailed description will follow but here is the best compromise between the different incarnations of the Justice League and the balance between realism and the superhero genre.
The Justice League has two types of communicators:
The first is a palm-sized device with a multitude of functions along with an extremely long range. This version cannot be used in combat.
The second device is a small compact gem-sized device that fits behind the ear. It has limited range and function but allows for communicating as easily as speaking.
The communicators are networked and work smoothly together all the way to the Watchtower (circumstances permitting) giving the impression that the communicators have more capabilities than they actually do separately.
