Pure Automation/Shattered Mecha

The Shattered Mecha is an Alternate Version of The Pure Automation, partially destroyed by its molten insides after Rialclaw manipulated its body to leak lava.

Appearance
Same as the Pure Automation but missing one of its hands. Its torso has multiple scars on it, as well as one of the bands being partially melted. Its skull has a few cracks on is.

Lore
(Please see Pure Automation for context)

After the Pure Automation was sealed, Rialclaw refused to give up on escaping. Rialclaw was able to find a weakness in the molten mechanisms and abused it, causing lava to leak. This caused the Pure Automation to start malfunctioning, melting its hand and creating scars and cracks on its body. Rialclaw then realized it was only a matter of time before the machine collapsed and set him free.

Phase 1
In the first Phase of the Shattered Mecha, it begins with six attacks, all listed below:

Molten Charge
The Shattered Mecha holds its pin next to its melted arm, before proceeding to do any attack regarding its pin. The attack enhanced by this will deal double the damage. This attack cannot be used after Phase 3 ends.

Great Slash
The Shattered Mecha will hold its pin behind its back, charging an attack. After about 1 second, a huge slash will be released, covering about half of the arena. This attack will deal two masks of damage. In Phases 3 and 4, the slash only covers 35%, and deals one mask. This attack is not used after Phase 5.

Triple Slash
The Shattered Mecha will slash in front of it three times, moving slightly forward each time. This attack is not used in Phase 5.

Dash Slash
The Shattered Mecha will hold its pin behind its back, charging an attack. After about 1 second, it will dash forward, before slashing. The dash covers about 75% of the arena, while the slash covers the rest. In Phase 3 and 4, the dash will only cover 50%, while the slash will only cover 15%. This attack is not used in Phase 5.

Leap
The Shattered Mecha will jump elsewhere in the arena. Rarely used in Phase 4, but not used in Phase 5.

Teleport
The Shattered Mecha will teleport elsewhere in the arena. Rarely used in Phase 4 and is even rarer in Phase 5.

Phase 2
In this phase, The Shattered Mecha begins to show its true strength, adding 5 new attacks.

Cyclone Slash
The Shattered Mecha will hold its pin behind its back, charging an attack. After about 1 second, it will perform a spinning slash, which can deal multiple hits in one use. The attack covers about 35% of the arena and can be used midair. When using midair, the Shattered Mecha will stay in its position until the attack finishes charging. In Phase 3, it only covers 20%, and can no longer be used midair. This attack is not used after Phase 4.

Molten Descent
While midair, the Shattered Mecha will stab its pin into the ground, and after a single second, creating an explosion of lava. The explosion covers around 50% of the arena. This attack deals two masks of damage. This attack deals one mask of damage in Phase 3. This attack is not used after Phase 4.

Flame Pillar
Similar to The Hollow Knight's Diving Flame Pillar attack, except with different visuals, faster eruption, and larger radius. This attack deals two masks of damage at first, but one mask in Phase 3. The attack is not used in Phase 4.

Molten Surge
The Shattered Mecha slashes its pin upward, before stabbing it into the ground and creating a firey shockwave. This attack deals two masks of damage. This attack is not used in Phase 4.

Lava Tendrils
The Shattered Mecha reveals its melted arm, and releases tendrils made of lava, which cover around 70% of the arena. This attack deals two masks of damage. In Phase 3, the range is decreased to 50%, and deals one mask. This attack is not used in Phase 5.

Phase 3
In Phase 3, the Shattered Mecha refuses to die to Hornet, and tries its hardest to fight back, but it is visible that its attacks are weakening. In addition, 4 new attacks are gained, mostly related to lava.

Flail
The Shattered Mecha slashes its pin above it multiple times. This attack is not used in Phase 5.

Scarring Act
The Shattered Mecha begins stabbing its scars multiple times, causing small explosions of lava. Contact with the lava deals damage. After the attack, the Shattered Mecha falls to the ground. This attack is always the first used when Phase 3 begins.

Eruption
The Shattered Mecha hovers in the air and begins releasing several blobs of lava from its scars. After the attack, the Shattered Mecha falls to the ground. This attack is not used in Phase 5.

Shattering Mask
The Shattered Mecha falls to the ground and roars, causing lava rain. This attack is caused by the cracks on its mask.

Phase 4
The Shattered Mecha tries its hardest to fight back, knowing it is failing. Most of its attacks are lost, but 3 new attacks are gained, while most of them are the attacks it had in previous phases, but interrupted.

Failing Cyclone
The Shattered Mecha attempts to perform a Cyclone Slash but does one cycle before falling. Contact damage is dealt in this attack. This attack is not used in Phase 5.

Failed Surge
The Shattered Mecha attempts to perform Molten Surge, but falls right after raising its pin. This attack is not used in Phase 5.

Descending Slash
The Shattered Mecha stabs its pin into the ground based on Hornet's location at the start of the attack. This attack has no extra effects. This attack is not used in Phase 5.

Phase 5
The Shattered Mecha loses almost all of its attacks, while at the same time gaining 3 more, which are purely failed attacks. It is visibly at the brink of death.

Failed Slash
The Shattered Mecha attempts to perform Great Slash or Cyclone Slash, but falls after finishing the charge.

Failed Dash
The Shattered Mecha performs a Dash Slash, but falls after performing the dash, cancelling out the slash.

Deterioration
The Shattered Mecha attempts to Perform a Triple Slash, but falls after performing one slash without moving forward at all.

Ending the Fight
After all of its health is depleted, the Shattered Mecha falls to the ground, but instead of being purely collapsed, it is unable to hold its pin, and is holding the crystal on its chest. To end the fight, the Shattered Mecha must be struck 15 times. After striking it all 15 times, soul begins erupting from its chest, and its mask keeps cracking. As the soul erupts, the magma in the background disappears, and after the Shattered Mecha's mask fully cracks, it explodes, and the screen goes black as it explodes. The Kindred Souls ending plays afterward.

Location
The Shattered Mecha is located within The Temple of The Scar, in the Void of Thorns.
