HEY! DON'T JUST FAVE THIS AND LEAVE! READ THE TEXT BELOW FIRST!
Please read the entry on Jeff Eyes [link]
and the series overview [link]
this will make little sense.
Watchers are giant Jeff Eyes, produced by Drone Leaders. They are typically about 1 and a half to 2 feet tall. Like Jeff Eyes, their eye color depends on the one the Drone Leader had when he or she was human. This one is Captain Jack's. A Watcher can fire a powerful laser from its eye, but it will die shortly afterwards. Unlike regular Jeff Eyes, Watchers can live up to 6 months and they show some degree of intelligence. They're just as easy to kill, though. They can also fly at near-supersonic speeds.
Watchers are commonly employed by Drone Leaders to survey a conquered area like Deninburgh Mental Asylum, which is now a Drone outpost/stronghold (all of the inmates and staff have been converted into Drones and Dummy Jeffs. More on that later.)
