The Beast

The Beast refers to a state which a BST-Frame can enter where it achieves exponentially higher combat performance.

The Beast has only been achieved by one machine one time, being BST-02 during the Cardaca Incident, and thus all information presented is based on that single instance.

Overview
The Beast, or Beast Mode, is a function in BST-Frames that allows them to go beyond their normal combat performance statistics. The mechanics of the system is not very well understood, and it is unknown if all BST-Frames possess the functionality, though it is suspected that it is indeed the case. During The Beast a BST-Frame exhibits a massive increase in power output, and as a result, an exponential increase in combat performance, enough to destroy even F-Armors with ease. The individual armor segments of the BST-Frame also separate, revealing a glowing frame underneath, and altering the appearance of the frame itself to appear more bestial. Additionally, the BST-Frame is capable of fully autonomous control during The Beast, able to ignore all pilot input even from a perfectly compatible pilot. In addition to the increase in general performance, the effectiveness of the BST-Frame's AD-Field increase to the point where nothing except another BST-Frame is capable of penetrating it, and even then just barely. Further, during The Beast, it would seem that anything less of completely dismembering and tearing the frame apart won't stop The Beast while it is active.

The purpose of The Beast is unknown, as is the reason why all BST-Frames would possess the system if that is the case, which it appears to be. The method for activating The Beast is also completely unknown, as BST-02 seemed to activate The Beast on its own in response to some unknown outside stimulus, and didn't stop until it was almost completely destroyed.
