Viper Probot has had every external component painted black as night, with attempts to minimize the brightness of external lights and features. This allows this Viper Probot to more easily blend into the shadows and darkness unseen.

Viper Probot has received advanced automated repair programming based on the original Viper Probot schematics, giving it an ability to perform or assist in the performance of self-diagnosis and self-repair of its mechanical systems. This system engages automatically upon damage, and can render the droid temporarily unavaialble while it assesses any necessary repairs before further action can be taken.

Viper Probot has developed a predatory nature similar to those often associated with assassin droids. As a result, Viper Probot will often approach a situation with the mind set of a hunter, and convey their findings as such. This can be disconcerting to others who are unaccustomed to Viper Probot.
