Lernaean Ignition

Lernaean Ignition (レルナエーン着火), also known as the Dagger of the Six-Headed Beast, is an Longinus-tier Sacred Gear wielded by Clyde Amaymon. It contains the spirit of, the Lernaean Hydra from Heracles' Twelve Labors.

Summary
In the past, the God from the Bible captured and revived the Lernaean Hydra, Kaross, and sealed it inside the Sacred Gear which eventually became one of the seventeen original Longinus.

Sometime before the beginning of the series, a previous possessor of Lernaean Ignition gifted this Sacred Gear to Clyde Amaymon.

Appearance
Lernaean Ignition takes two forms: a silver dagger and as the Lernaean Hydra, where it is a giant four-headed greyish-silver Hydra.

In it's dagger form, it is predominately greyish-silver. On the back of the blade there is a small snake-like creature on it, with green eyes.

Abilities
Lernaean Ignition takes the form of an dagger which can create and control a extremely toxic venom, and create fire. The Longinus' second ability is to create serpents and snakes of fire and/or venom.

Tyrian Sea Beast
Tyrian Sea Beast (ティリア海獣, Tiria kaijū): Also known as the Imperial Scale Skin of the Lernaean Hydra, Lernaean Ignition's Balance Breaker, which creates a silver and green, dragon-themed armor that covers the user's body. The armor also protects the user from projectiles. It was first used by Clyde Amaymon during his Rating Game with Maho Gremory.

Tyrian Amaymon Empire Sea Beast
Tyrian Amaymon Empire Sea Beast (ティリアンアマイモンエンパイアビースト, Tirian amaimon Enpaia bīsuto), also known as the Imperial Stone Scale Skin of the Lernaean Hydra's Empire, is Lernaean Ignition's Breakdown the Beast. This form unleashes the full power of the Lernaean Hydra, but also like Juggernaut Drive, the user's life force is used as the power source. In this form, Clyde's armor changes color to silver, green and white, and he is enveloped by an immensely dense, green aura. It possesses immense power, allowing Clyde to easily overwhelm the Sloth, the third-strongest of the Seven Deadly Sins. However, the time he can sustain this form is very short, and after would feel immense pain.

Clyde and Kaross alternate lines when chanting the Breakdown the Beast chant.
 * Clyde: “This body, this soul, when it falls into an eternal venom sea!”
 * Kaross: "My King and I, we will exhaust this body and soul to drown the endless land and bring forth the flood!"
 * Clyde: “Ravage, triumph, gnaw, and drown!”
 * Kaross: "This is the essence of a Demonic Serpent!"
 * Clyde: “Lodged on my dagger, is the glorious tyrian blood!”
 * Kaross: "Screech!”
 * Clyde: "Screech!"
 * Both: “Descend!!!”
 * Both: “Breakdown The Beast, Climb Over!"
