Energy fences project walls of visible, deadly energy. Anything touching one of these fences is repulsed by the equivalent of a heavy repeating blaster bolt. While these are formidable defensive systems, a sufficiently powerful individual field disruptor allows the wearer to slip through unharmed, although the disruptor does nothing to counteract sensors, trip lasers, and other common security systems.

Individual field disruptors have one notable drawback - if they cannot compensate for the fence's power rating, a person wearing a disruptor will suffer the full brunt of the fence's blast.

First released during the reign of the Empire, the Evasive-13 is one of many individual field disruptors on the market. Its fifteen-centimeter-long case holds the power cell, a control computer, and twin projection shells. Each of these holds a disruption bubble unit. Sliding the twin shells away from the power cell will activate the unit, at which time the twin disruption bubble integrators generate a small energy field, completely enveloping the user.

At the minimum setting the Evasive-13 can pass through low-power fences, and the power cell lasts for over an hour of continuous use. However, maximum output, which is necessary to counteract many military-grade fences, drains the cell in less than four minutes. The Evasive-13 also can be used as a close-quarters weapon, since anyone who touches since anyonw who touches a full-power disruption field receives a very nasty and sometimes fatal energy blast.

When it was released over a decade ado, the Evasive-13 used cutting-edge (for the time) disruption bubble technology and had a price of over twenty-five thousand credits. More advanced disruption bubble generators have become available - in turn leading to the development of more powerful energy fences - so that the Evasive-13 is now considered a midlevel system, and its price has dropped to around eight thousand credits. The Evasive-13 can defeat most civilian energy fence systems, but many military units have high enough energy ratings to counteract this disruptor.

Evasive-13 disruptors were used by paramilitary operatives who planned to kill the infamous Doctor Evazan by infiltrating his secured fortress on the planet Ando. These agents, hired by families that had been victimized by the insane doctor's failed experiments, used disruption bubble generators to slip through several layers of power screens, but their attack was foiled and they were killed by Evanzan and his companion, the Aqualish thug Ponda Baba.

Military operations specialists have access to much more sophisticated disruption bubble generators. Elite Imperial Storm Commandos and the New Republic's top operatives, Page Commandos, often use advanced field disruptors such as the Aeramaxis Evasive-226-R.
