The Zero System

Mechanism:

In the After Colony Era (Gundam Wing), Newtypes no longer exist, instead a device strangely familar has been used to enhance the pilot's ability, giving them temporary Newtype ability. This device was named the ZERO SYSTEM, in which the 5 scientists (its inventors) claimed, "should have never been invented."
    This device works on the basic principle of integrating the pilot's
brain waves with the actual MObile Suit.  All information that is detected by the system's sensors are immediately transmitted to the

pilot's brain directly. It bypasses the normal human receptors of sight (eyes), sounds (ears), taste & smell (tongue and nostrils) and touch (touch sensors) and striaght to the brain. Furthermore, any information or thoughts that the pilot is contemplating or pondering about will also be detected by the ZERO SYSTEM. The system will then analyse and edit these "thoughts" and transmitt the "thoughts" back to the pilot's brain within nanoseconds. Thus, the reaction-time of the pilot is almost down to zero, as the system has become his "eyes and ears" so to speak. The neuro-sensory-system of the pilot will be stimulated and his combat skills increases exponentially.
    The ZERO SYSTEM was installed into 3 mobile suits only: The WING GUNDAM ZERO, GUndam EPYON, and also GuNDAM SANDROCK

Dangerous Side-Effects:

   Similar to the Psychommu systems in the UC era, the ZERO SYSTEM also have some dangerous side effects. Just like ZETA-Gundam's Biosensor, the ZERO SYSTEM places immense mental burden onto the pilot's brain. The average pilot can not cope with this pressure, and their brain will suffer from information overload, inducing them to lose sanity. (reminescent of Carmille Vidan from Zeta-Gundam)
    The ZERO SYSTEM has another even more dangerous side effect. As mentioned before, the
ZERO SYSTEM tracks down all enemy targets and feed them directly into the pilot's mind.  It will also analyse any thoughts that the pilot have in his mind. Thus, if there are no physical targets nearby, the ZERO SYSTEM will continue to search for potential enemies, anything that lurks within the pilot's brain (anything that slightly annoys him or have doubt about) will be interpreted by the system as an "enemy". The system will then edit this information and transmitt it back into the pilot's brain immediately. Now a simple idea or thought has turned into a "real enemy" in the pilot's mind, and he will not stop until that "enemy" is destroyed. Once that has been done, the
process restarts again and the pilot will find his next "enemy". Therefore, the danger with the ZERO SYSTEM is that it causes the pilot to see anything that is remotely threatening, or anything that makes him angry, as his enemies... inducing him into a continual killing spree until the pilot dies from information overload.

Only Heero Yuy and the eventual owner of the WingZERO was able to master this system successfully.  Miliardo Peacecraft was also able to control it to an extent.

Like to thank [email protected] for the telling me that GUNdam Sandrock was also installed with the zero system...
