Juggernaut Drive, also known as the Dragon of Supremacy, is a special ability of the Longinus - Boosted Gear and Divine Dividing.


A special ability of the Longinus - Boosted Gear and Divine Dividing, and are considered to be forbidden moves. The Juggernaut Drive temporarily removes the seal placed on the Heavenly Dragons, but the users will lose their sanity while their lives are devoured by the power.

Juggernaut Drive contains a curse made up of the negative emotions of the past possessors of the Boosted Gear and Divine Dividing that influences the current user to enter this form. The curse of the Juggernaut Drive can be permanently removed if the hatred of its past possessors are dispersed.

For other Sacred Gears that have creatures sealed inside (such as the Regulus Nemea), 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.


A special chant must be used to activate Juggernaut Drive.

The chant for the Boosted Gear's Juggernaut Drive goes as follows:

I, who is about to awaken,
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!


Ware, mezameru wa
Ha no ri o kami yori ubaishi Nitenryū nari
Mugen o warai, mugen o ureu ga
Ware, Akaki ryū no haō to narite
Nanji o guren no rengoku ni shizumeyou

The chant for Divine Dividing's Juggernaut Drive goes as follows:

I, who is 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
And I shall take you to the limits of white paradise


Ware, mezameru wa
Ha no ri o kami yori ubaishi Nitenryū nari
Mugen o netami, mugen o omou ga
Ware, shiroki ryū no hadō o kiwame
Nanji o muku no kyokugen e to izanaou


In Volume 6, 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, Shalba found himself overpowered and incapable of defeating Issei, but manages 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 exit Juggernaut Drive by poking Rias' breasts.

In Volume 7, Vali activated the Juggernaut Drive during the battle against 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 Volume 10, during his fight with Sairaorg, Issei nearly entered Juggernaut Drive again under the negative influence from the past possessors. However, he managed to resist it and change the view point of the possessors. As a result, Issei soon found himself equipped with a new form called the Cardinal Crimson Promotion.

In Volume 12, Vali had achieved an new enhanced form that surpasses Juggernaut Drive by sealing all of the past possessors' consciousness, the new form is called Empireo Juggernaut Overdrive.


The Juggernaut Drive unleashes the full power of the Two Heavenly Dragons sealed in both the Boosted Gear and Divine Dividing, granting the user power that is said to rival that of gods or Maou. The immense power is so great that, upon activation, its aura would have destroyed the local areas.

While in this form, the user has a greatly increased flight speed to the point where it can be hard to follow with ones eye sight. This form is also capable of fending off powerful 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 dragon. On top of that, the user obtains the ability to shoot laser out of their mouth.

While in Boosted Gear's Juggernaut Drive, Issei somehow froze Shalba Beelzebub with an ability similar to Forbidden Balor View, this was later revealed to be Gasper Balor's doing, as he was allowing Issei to use his "eyes".

Issei's most powerful attack is the Longinus Smasher, previously only available in the Juggernaut Drive. An energy beam of immense destructive power fired from a launcher hidden in the chest.


Despite its overwhelming power, the Juggernaut Drive is a double-edged sword. During application, the user will find themselves abundant with newfound abilities and enhancements powers, however, it comes with a price of losing their sanity and life. After activation, the user will obliterate every surrounding, 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.


Juggernaut Drive in the anime appears very similar to the Scale Mail, however it takes a gigantic form with a much more Dragon-like appearance, possessing claw-like growths on the hands and feet, as well as horns and a fanged mouth on the helmet, the mouth being capable of delivering deadly bites to opponents.


  • Juggernaut Drive was originally stated to be a special ability which was exclusive for Sacred Gears with powerful creatures inside. Though in Volume 11, it was changed to a special ability exclusive for Sacred Gears with the Heavenly Dragons residing in them (Boosted Gear and Divine Dividing). For other Sacred Gears with other creatures residing in them, a new name, called Breakdown the Beast, was given.
  • The "infinity" and the "dream" used in the chants are references to the Dragon God Ophis and the True Dragon, Great Red. Ophis represents the "infinite", as she was born from the "nothingness" of infinity, while Great Red represents the "dream", as he was born from the "illusions" of dreams.
  • Longinus Smasher appears to be a homage to the Mega Smasher from the Guyver series.
  • In the english dub of Season 2, Vali shortens the name to just "Juggernaut". During the events of Season 3, however, he and Issei both refer to it by it's full name.
