**Juggernaut Drive**, also known as the **Dragon of Supremacy**, is a special ability of the Original Longinus, Boosted Gear and Divine Dividing or Neo-Longinus, Zephyr Shift and Burning Soul.

Other Sacred Gears that have creatures sealed in them such as the Longinus, Regulus Nemea or Lyngvi Vánagandr and Others possess their own particular ability referred to as **Breakdown the Beast**, also known as **Beast of Supremacy**.

## Summary

Juggernaut Drive is a special ability of both the Mid-tier Longinus, Boosted Gear and Divine Dividing or High-tier Longinus, Zephyr Shift and Burning Soul, and are considered to be forbidden moves, even among the various techniques associated with the Sacred Gears. It temporarily removes the seals placed on the Heavenly Dragons, but the users will lose their sanity while their lives are devoured by the power.

It contains a curse that is made up from the negative emotions of the past possessors of the Boosted Gear and Divine Dividing which influences the current user to enter this form, though it can be permanently removed if the hatred of its past possessors is dispersed. Because of the curse, after its first activation, it will leave the Sacred Gear in a state where the thoughts of its past possessors are released and invade the current user's mind, slowly driving them to insanity.

For other Sacred Gears that have creatures 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*), also known as the **Beast of Supremacy**, but functions the same way.

The form made its official debut in Chapter, when Issei unintentionally activates an incomplete form of Juggernaut Drive due to the overwhelming negative feelings after Asia's apparent "death" at the hands of Shalba Beelzebub. Issei went berserk and ripped Shalba's arms off, with Shalba finding himself overpowered and incapable of defeating Issei, but managing to escape at the last second. The Oppai Dragon's theme song was played to calm Issei enough for Vali to reduce Issei's power and later exited Juggernaut Drive by poking Rias' breasts.

In Chapter XXX Vali activated the Juggernaut Drive during the battle against Utgard-Loki, however, unlike Issei, he was able to temporarily negate the Juggernaut Drive's negative effects by using his demonic power as a source instead of his life force. He was then teleported by Kuroka to fight against Fenrir elsewhere.

In Chapter XXX, during his fight with Sairaorg Bael, Issei nearly entered Juggernaut Drive again under the negative influence from the past possessors. However, he managed to resist it and change the viewpoint of the possessors. As a result, Issei soon found himself equipped with a new form called the **Cardinal Crimson Promotion**.

In Chapter XXX, Vali had achieved a new enhanced form that surpasses Juggernaut Drive by sealing all of the past possessors' consciousness, the new form is called **Empireo Juggernaut Overdrive**. The form Breakdown the Beast was debuted in Chapter XXX by Sairaorg when facing off against the former 3rd Ranker of the Rating Games, Bedeze Abaddon.

## Abilities

### Juggernaut Drive

Juggernaut Drive unleashes the restraining seals placed on the Heavenly Dragons sealed in both the Boosted Gear and Divine Dividing, granting the user powers that are said to either rival or even surpass that of the gods or Satans. Their physical and magical capabilities are greatly enhanced that, upon activation, its aura alone would have destroyed the urban areas of the mortal world. Like the Balance Breaker state, the user can use [Boost] or [Divide] without the 10-second limit in this form.

While in this form, the user gains a pair of giant dragon-like skeletal wings which grants them a greatly increased flight speed to the point where it reaches the speed of sound and becomes difficult to follow even with magically reinforced eyesight. This form is also capable of fending off powerful magical attacks by simply flapping its wings. From the various jewels all over the armor, the user can grow multiple limbs and blades akin to the appearance of a western dragon. On top of that, the user obtains the ability to shoot lasers out of their mouth.

Its most powerful attack is the **Longinus Smasher** (ロンギヌス・スマッシャー, *Ronginusu Sumasshā*), previously only available in the Boosted Gear's Juggernaut Drive. It is a beam of destructive energy fired from a hidden launcher within the user's chest piece. According to Odin, the last recorded user to use it has blown away entire mountains and islands from the world maps in the span of days.

### Breakdown the Beast

Breakdown the Beast functions in practically the same manners as the Juggernaut Drive, as it grants the user immense increase in their physical and magical capabilities in exchange for their sanity and life-force. However, unlike Juggernaut Drive, it also grants the user many signature abilities belonging to the sealed creature inside, such as Regulus' ability to fend off all creations of men or the Leviathan's ability to control all marine creatures of both mundane and supernatural nature.

Breakdown the Beast unleashes the restraint placed on Regulus sealed in Regulus Nemea, granting the user power that is said to rival or even surpass that of the gods or Satans. The immense power is so great it sends out a wave of power that is even strong enough to temporary suppress the flames of Agni. It increases Sairarog's strength, speed, durability and further strengthens his Touki as it takes on a purple color. His speed exceeds Kiba Yuuto, who is noted as a extremely fast and skilled swordsman.

## Chants

A special chant is needed in order to activate the Juggernaut Drive:

*Am the Heavenly Dragon who has stolen the principles of domination from God*
*I laugh at the "infinite", and I grieve at the "dream"*
*I shall become the Red Dragon of Domination*
*And I shall sink you to the depths of the crimson purgatory!* | *I, who am about to awaken,*
*Am the Heavenly Dragon who has taken the principles of supremacy from God*
*I envy the "infinite" and I pursue the "dream"*
*I shall become the White Dragon of Supremacy*

*Am the Heavenly Dragon who has destroy the principles of harbinger from God*
*I protect the "infinite", and I treat at the "dream"*
*I shall become the Black Dragon of Annihilation*
*And I shall sink you to the waive of the darkness star* | *This body, this soul, even if it falls into an endless ravine!*
*My Lord and I, we will exhaust this body and soul to rise up endless royal road!*
*Raze, triumph, play, and shine! This is the body of a Demonic Beast!*
*Lodged on top of my fist, is the glorious imperial authority!*
*Dance! Dance!*

## Drawbacks

Despite its overwhelming power, both the Juggernaut Drive and Breakdown the Beast are a double-edged sword. During the application, the user will find themselves abundant with newfound abilities and enhanced powers, and with those, immense repercussions. After activation, the user will lose their sanity and will obliterate everything in their surroundings, leaving very little to no trace. Formerly, the only way to put an end to this rampage was when the user would eventually and inevitably destroy themselves.

The forms' main danger is its consumption of the user's life-force as a fuel source. Vali is a rare exceptional case as he is able to enter the Juggernaut Drive state without endangering his life-force by using his demonic power as a substitute, but he will go berserk if he uses it for too long. However, in spite of all this, Vali cannot control the Juggernaut Drive, but enforces some of his will. Another exception would be Sairaorg, who still manages to keep his sanity in place while having his life-force drained while using Breakdown the Beast.

## Trivia

* Juggernaut Drive and similarly Breakdown the Beast were named so because they bring out a huge, powerful, and overwhelming force that forces the user into a specified negative state.
* The "infinity" and the "dream" used in the chants are references to the dragon gods, Ophis and Great Red. Ophis represents the "infinite", as their essence is the "nothingness" of infinity, while Great Red represents the "dream", as her essence is the "illusions" of dreams.
* According to Vali, a complete transformation is permanent, but it is possible to change back if the transformation is incomplete.
* While they are a set of Sacred Gears, not a singular one, the Vritra's Sacred Gears' Malebolge Vritra Promotion can be considered a Breakdown the Beast.
