Boosted Pump

Boosted Pump, also known as the Red Dragon Emperor's Gauntlet, is a Ancient Gear wielded by Arthur Pendragon. Listed as one of the nineteen Longinus, it has the spirit of the Welsh Dragon, Ddraig, residing within it.

Summary
In the past, Ddraig fought against his arch-rival, the Vanishing Dragon, Albion, in a battle that was interrupted by the Vampyre's, Seraph's, Devil's, Fallen Angel's, and Hero's who were at war during the time. In anger, both Dragons attacked the leaders of the Five Factions, which led to their bodies being destroyed and their souls being sealed into two separate Ancient Gears, with Ddraig moving into the "Boosted Pump", a Ancient Gear that eventually became one of the nineteen varieties of Longinus.

In Volume 7, it is revealed that when a host of the Boosted Pump dies, a fragment of their consciousness is stored inside the Boosted Pump normally only waking up during the activation of the Juggernaut Drive. However, there are two people who maintain a degree of consciousness; Belzard Jonathan and Elsha Scarlet. Belzard is known as the strongest Greater Boost possessor for defeating two White Dragon Emperors in his lifetime, while Elsha is known as the second strongest and the strongest female.

In Volume 8, it is revealed that a past possessor of Divine Dividing was stored within the Boosted Pump when Arthur used one of Albion's jewels to create the Greater Dividing. The past possessor of the Divine Dividing then used his halving power to diminish the dark thoughts of the Boosted Pump's past possessors, allowing Arthur to awaken a power opposite to Juggernaut Drive: Cardinal Crimson Incursio, with a different chant.

In Volume 12, all the past possessors sacrificed themselves in order to save Arthur's soul from Samael's curse.

In Volume 16, Euclid Lucifuge reveals that he created a replica version of the Boosted Pump by collecting information of the Red Dragon Emperor's soul and the Ancient Gear from Arthur's original body that was left in the Dimensional Gap by using the Holy Grail. Unlike the original Boosted Pump, however, the Boosted Pump Replica appears on the user's right hand with silver lining and uses the souls of famous Dragons to activate it. In the following Volume, the replica was destroyed after Euclid's defeat against Arthur.

In Volume 18 Arthur and Ddraig unlocked one of Ddraig's original powers called Penetrate that allows Arthur to bypass defensive powers, such as Drakon's Ancient Gear canceller.

In Volume 20, Arthur uses a new chant that he, Brynhildr and Ophis chant, alternating lines, that allows him to temporarily borrow Ophis' power of infinity. Ddraig names the new form Diabolus Dragon Beast or DxDxB.

In True Volume 4, as a result of taking the miracle drug Shiva offered Arthur, he is now able to summon Ddraig and/or Brynhildr from the Boosted Pump for a certain amount of time.

Appearance
Boosted Pump takes the appearance of a red gauntlet with a green jewel and 2 golden spikes that manifests on the user's arm. After a certain time, it transforms into a more Dragon-like gauntlet that covers up the user's hand and a majority of the arm. When the Boosted Pump reaches its second liberation, it gains another green jewel and a total of 10 golden spikes, aside from covering more of the user's arm.

Abilities
The Boosted Pump has the ability to Boost which can double the user's power every 10 seconds. With further changes in response to the user's feelings, the Boosted Pump can activate the sub-ability to Transfer the increased power to other people or objects. The transferred power can be performed on multiple people/objects at the same time, however, this decreases the efficiency, and some of the power will be lost in the transfer. This can also be used on a certain part of the user's body such as the eye's for enhanced vision.

In Volume 3, Boosted Pump gains the ability to determine an opponent's power level and tells Arthur when his boost has built up sufficient power to possibly defeat an opponent, either by utilizing it himself or transferring it to an ally. However, this ability has not been used since the fight with Gadreel.

In Volume 4, the Boosted Pump has also been shown to be able to store powered weapons and items within it and allowing the user to wield their capabilities, such as the Holy Sword Excalibur (after some adjustments) and a jewel from Divine Dividing's Scale Mail. Storing the item is all dependent on the user's will

In Volume 18, Ddraig unlocked the power of Penetrate, this allows the user's attacks to hit, even through powerful defensive barriers. Arthur soon adapted the ability to grant him the power to see through solid objects (i.e Clothing) at will.

In Volume 19, Arthur managed to reverse the effects of Transfer's initial ability, so that he could take power from Vidar instead of giving power

In Volume 21, Arthur unlocked the strongest of Ddraig's original powers, called Blazing Inferno of Scorching Flames.

Weaknesses
With Ddraig sealed within the Boosted Pump, its possessors become vulnerable to Dragon-slaying magics, swords and curses as if they themselves were Dragons. Also, continuous use of the Boosted Pump will drain the wielder's stamina to a significant degree.

Red Scale Mail
Red Scale Mail, also known as the Armor of the Red Dragon Emperor, is the Overdrive of Boosted Pump which creates a Red Dragon Armor with green jewels that cover the user's body and strengthens its powers and abilities. When active, the user can double their power without the 10-second time limit, this also applies to later forms. The armor has two rocket thruster on it's back for a temporary boost of speed and flight, from them can come out a two pairs of retractable Dragon wings that enables the user for proper flight. Originally, it did not have wings, however, after Arthur goes into Juggernaut Drive in Volume 6, it gains Dragon wings.

Juggernaut Drive
Juggernaut Drive, also known as the Tyrant of Supremacy, like Divine Dividing, Boosted Pump also has access to this form. This form unleashes the full power of the Welsh Dragon, but the user will lose their sanity and their life will also be devoured. Arthur first went into Juggernaut Drive in Volume 6, which would also be his last time. It also has access to the Longinus Smasher, one of the most powerful attacks of the Boosted Pump.

Incursio Move Andernach
Incursio Move Andernach is the enhanced form of Arthur's Scale Mail, where the armor changes to various forms based on the Evil Pieces' traits.

The available forms for the Incursio Move Andernach are:
 * Welsh Incursio Sonic Knight
 * Welsh Incursio Panzer Rook
 * Welsh Incursio Alamos Bishop

Cardinal Crimson Incursio
Cardinal Crimson Incursio, also known as the True Crimson Invasion Dragon Emperor, is the Scale Mail's evolution of the Queen form. It changes the color of Arthur's Scale Mail armor from red to crimson. Cardinal Crimson Incursio incorporates all three Evil Pieces traits, making it the most balanced and most powerful form of Arthur's Scale Mail. It is Arthur's answer to a power different from the Juggernaut Drive.

Diabolus Dragon Beast
, is a new form Arthur gained in Volume 20 from tapping into his mother, Ophis' and Wagyl's power inside him. This is due to the fact that his body is made from Scarlet Grand's flesh, which enables Arthur to temporarily borrow Ophis' and Wagyl's power. In this form, the armor becomes "organic" changing the armor's shape, and the armor's color changes from pure crimson to a mix of crimson, white and black. Additionally, this form gains a total of six wings, each one containing a cannon. Two of the cannons are over his shoulders and the other four are under his arms. In this mode, the Boosted Pump's announcement voice becomes an amalgamation of Ddraig, Brynhildr, Ophis and Wagyl's voices and instead of "Boost", the Boosted Pump announces "D∞B" as Arthur directs his mother's infinity power. Diabolus Dragon Beast grants Arthur Ophis's power of infinity and Wagyl's power of dream, enhancing him to the point at which he was able to easily overwhelm both Drakon La Leviathan and Rizevim Livan Lucifer, overpowering the former's Ancient Gear Canceller. Diabolus Dragon Beast's finishing move is the Longineus Infinity Blaster, a powerful aura blast in which Arthur directs Ophis' and Wagyl's powers to the six cannons stored in the armors wings, then fires them. The Longineus Blaster is so powerful that the blast left Cythraul injured to a extent that his body is almost fatally damaged. According to Drakon, Diabolus Dragon Beast has similar features to the Juggernaut Drive without the ominous aura. However, the time Arthur can spend in DxDxB mode is very limited, and after the armor is released, Arthur experiences immense pain throughout his entire body and becomes comatose.

Arthur, Brynhildr and Ophis alternate lines when chanting the Diabolus Dragon Beast chant.
 * Arthur: "The Crimson Red Dragon Emperor and Strongest Valkyrie dwelling within me, awaken from your domains of dominance"
 * Brynhildr: "The Crimson Heavenly Dragon I possessed, rise up to become a King and roar a plaza of flames"
 * Ophis: "The jet-black Goddess of Infinity"
 * Brynhildr: "The glorious Gods of Dreams and Dreamtime"
 * Brynhildr and Ophis: "Watch over the (false) forbidden existence we shall become that transcends the boundaries"
 * Both: "We shall dance like radiance within our inferno!"

Following Arthur's battle against Cythraul, Ophis adjusts the D×DxB to prevent the severe backlash of that form and is subsequently renamed the D×D×B・L in tandem with Vali's D×D×B・P and later Lancelot's D×D×B・V. In Volume 22, a modified version of chant was used by Arthur. In Volume 25, after drinking the miracle drug Amrita, Arthur can maintain his Pseudo-DxDxB form for 88 minutes in combat.

Apocrypha AnswerArms
Apocrypha AnswerArms : Arthur's AxA form. This form is the result of Arthur combining with his familiar Garmr, who is the manifestation of Scarlet Grand's power. The power of this form is so great that it overwhelms Tartarus a Primordial God in Greek mythology. It has the power to destroy the entire world with it's destructive power. Because of the weapons that was installed in Garmr, Arthur has gained new abilities of this form. The drawbacks of this form is that it has an extremely high consumption rate which gives it a short time limit. Furthermore, Garmr is unable to move for a few days and Arthur himself suffers fatigue for a few days. It is determined that these burdens compared to DxDxB-L are much lighter.

Super Gigantic Overdrive
Super Gigantic Overdrive is the form that Arthur takes after combining with Scarlet Grand in Volume 12. It resembles Greater Boost's normal Scale Mail, except that it is incredibly enormous in size and now has access to the Longinus Smasher that was previously exclusive to the Juggernaut Drive.

Crimson Vampiria Dragonar
Crimson Vampiria Dragonar, also known as The Death Scarlet Destroyer Vampyre Princess, is a form developed for Mina, which is a combination technique between Arthur and her. Arthur uses his Red Wyverns and sync both of their auras while the Wyverns attach themselves to Mina to create her own female variation of the Scale Mail. The armor acts just like the original, strengthens Mina's abilities and giving her the ability to utilize Boost, Transfer, and Penetrate until she reaches her limit.

Crimson Clear Dragonar
Crimson Clear Dragonar, also known as the Death Scarlet Destroyer Dragon Knight, is Tomoe's own variation of the Scale Mail armor, which she gained by also synchronizing her aura with Arthur's to use his Red Wyverns to attach themselves onto her body which shifts into the form of armor. Like the original, it has all of the same functions of Boost, Transfer and Penetrate. This is noted to be similar to Mina's and yet different.

Crimson Succubus Dragonar
Crimson Succubus Dragonar (クリムゾン・サキュバス・ドラグナー, Kurimuzon Sakyubasu Doragunā) is Hinami's own variation of the Scale Mail armor, which she gained by also synchronizing her aura with Arthur's to use his Red Wyverns to attach themselves onto her body which shifts into the form of armor. Like the original, it has all of the same functions of Boost, Transfer and Penetrate. Like Tomoe's, this is noted to be similar to Mina's and yet different.
