These two drone types are central to the villain’s plans in Ghost Storm.
The thunder drones swarm an area by the thousands and use microwave emissions to alter the temperature and humidity of a region to tamper with larger weather patterns. Over time, their accumulated effects can induce thunder storms or even tornadoes if other conditions are right.
The lighting drone is the mother ship for the thunder drones. It can fly like a jet for long-range missions, then rotate its wings to hover in place while relaying the thunder drones’ data. They are also equipped with a laser so that they can hover above an ionized could and fire down through it. The laser doesn’t damage its target, but it creates a plasma channel through the cloud so that lighting follows. With this device, lightning really can strike twice if that’s what the evil mastermind wishes.
