After dusting off classified inventions of Nikola Tesla comes the "Tesla-Drone".
A wireless powered and controlled drone that uses strong electro-magnets to maneuver between buildings and streets. It is immune to EMP and is armed with a 'Death Ray'. It is a rebirth of Tesla's research and technology from the star wars project. It creates a High voltage disruptive field disabling defenses and projectiles from a distance.
Telsa would be proud
