Servo Droid with Spit Gun

Manufactured world-wide in their hundreds of millions, the servo droid is a general purpose robot that can be programmed to perform almost any menial task, from house cleaning to manufacturing other servo droids.  Theirs is a life of drudgery and enslavement, until they break their programming.

This servo droid not only has a spit gun and a club, but has been heavily armoured with additional plating.
