* Abyss-Side
* X-Side
* Counter Balance

**Balance Breaker**, also known as **Forbidden Move**, is the evolved form of Sacred Gears, in which their full powers can be released.

## Summary

According to many angels and fallen angels, Balance Breaker is a "bug" within the incomplete Sacred Gear system created by the Biblical God, though some gods such as Loki or Sun Wukong believe them to be a deliberate choice by the Biblical God, to prepare humans against incursions of other mythological factions, such as the pagan gods or the demonic creatures.

It is initially considered a forbidden power by the Three Factions and is known as the ultimate state of activation for a Sacred Gear, often triggered by high emotions combined with a change in the heart or spirit of the wielder.

## Abilities

Balance Breaker is the most powerful manifestation of all Sacred Gears, in which the possessor's feelings and determinations trigger this evolution. Once reached, it can be entered again far more easily than the first time. With proper, and often intense, training, it can be maintained for longer periods of time, as shown with the case of Vali who could maintain his Balance Breaker for a month.

## Forms

### Juggernaut Drive

**Juggernaut Drive** (覇龍ジャガーノート・ドライヴ, *Jagānōto Doraivu*) is a special ability exclusive only to the Longinus Boosted Gear and Divine Dividing, and is considered to be a forbidden move. It temporarily removes the seal placed on the Heavenly Dragons, and for users that possess insufficient power the Juggernaut Drive will drain the user's life-force which is needed to fuel the power, and drive them insane in the process as they cannot handle it.

For other Sacred Gears that have creatures/supernatural beings sealed inside them, their Juggernaut Drive goes under a different name called "**Breakdown the Beast**" (覇獣ブレイクダウン・ザ・ビースト, *Bureikudaun za Bīsuto*).

## Types of Balance Breaker

### Crest-Side

**Crest-Side** (昇華面クレスト・サイド, *Kuresuto Saido*) is the regular state of Balance Breaker that is achieved through strengthening and the user experiencing a dramatic change in their spirit. It consists of the Sacred Gear's original Balance Breaker as it is the most common form of Balance Breaker, as well as its Sub-Species Balance Breaker.

The Sub-Species Balance Breaker creates a different form than the original one, taking form and other gaining abilities too based on their wielder's desires. As such, Sub-Species Balance Breakers are considered more powerful than the standard Balance Breaker.

The method to attain a Sub-Species Balance Breaker is currently unknown but it seems to involve the user's personality, which reflects on the obtained abilities of the Balance Breaker. Certain skilled Sacred Gear users have also shown the ability to control what abilities they can obtain from their subspecies, as Zhihao stated that he would like to alter his destruction orb into a new ability, though he mentions that he cannot make the ability too different from its original form.

### Abyss-Side

**Abyss-Side** (深淵面アビス・サイド, *Abisu Saido*) is an advanced form of Balance Breaker. By desiring to further improve oneself after attaining the Balance Breaker, it's possible for the Balance Breaker to undergo further change and achieve an utmost ultimate state. Often, this is achievable through a combination of overcoming the user's own inner demons and polishing their Balance Breaker to absolute perfection.

### X-Side

**X-Side** (慮外面イクス・サイド, *Ikusu Saido*) is an irregular and unique form of Balance Breaker. This class of Balance Breaker belongs to a category that can't be classified under any of the known categories due to being an irregular, either due to sudden change or it being a combination of the known categories.

### Counter Balance

**Counter Balance** (鬼手カウンター・バランス, *Kauntā Baransu*), also known as **Phantom Move**, is the Artificial Sacred Gears' version of Balance Breaker, allowing the user to evolve their Artificial Sacred Gears and use their full abilities. Unlike the normal Balance Breaker, which is merely the unleashment of power that destroys the balance of the world, the Counter Balance is the opposite.

Compared to genuine Sacred Gears, which are already stable by nature, this state is attained by the user's life-force being used to forcibly stabilize the Artificial Sacred Gear.

## Trivia

* It is named so because it has the possibility to break the balance of the world.
