Spy Bot

Some robots have it easy, these Robots have a mission. Specifically made for Spying or Espionage missions. They dodge bullets, perform recon, shape-shift, whatever is necessary to find out what someone else doesn't want them to know. While their design can overlap with the Surveillance Drone they are more closely related to Androids and Detectives.
