Absolute Defense System

The Absolute Defense System is the most powerful shield system personally installed on the Knightmare Frame, Shinkirō for the use of Zero (Lelouch vi Britannia).

Background
The Absolute Defense system creates hexagonal shields that overlap each other to form a defensive grid. This shield system is used in conjunction with the Druid System to plot trajectories of weapon fire along with a personalized control system in order to properly set up an effective defensive pattern. The color of this shield system is of a translucent red.

However, it is later revealed that the Shinkiro's Absolute Defense System is unable to block the Tristan Divider's Excalibur MVS at close range.

Weaknesses
The Absolute Defense system has four known weakness.
 * 1) In order for offensive capablities to be use, the Absolute Defense system must be turned off.
 * 2) Requires high intellect in order to create enough strength and protective coverage for maximum effectiveness of the Absolute Defense system.
 * 3) Continual high-yield blast (like continuous point-blank fire from the Mordred's Stark Hadron Cannon) in close proximity to the Absolute Defense system will severely deplete energy and cause drastic decrease in defensive strength.
 * 4) An attack powerful enough over relatively small area of contact (namely Excalibur Sword, or even just half of it) cause the system unable to distribute the force evenly among its grid, causing reduced defensive efficiency and lead to the shield upon that area of contact collapse.
