The infamous bigger than the universes/multiverses Demonbane.

Name: Demonbane (actual name), Mars / Four Legged War God / Gunshin Kyoshuu Demonbane
Pilot: Hadou Kouzou and Little Ada | Edgar and Al Azif
Origin: Demonbane
Height: 55.5 meters | Immeasurable (can grow larger than the universe) | Larger than several universes
Weight: 4225 tonnes | Immeasurable | Immeasurable+
Powered By: Cor Leonis + Heart of Infinity (both drawing unlimited energy from the multiverse) | Cor Leonis + Lamp of Alhazred (aka Edgar himself)
Destructive Capacity: At least planet level+ (the aftershock from Atlantis Strike was enough to shake a portion of the Asteroid Belt from hundreds of millions of kilometers away) | Universe level+ (they were popping universes one after another) | Multiverse level (outgrew a Klein Bottle which is a timelooped universe as well as saw several universes get destroyed)
Range: Unknown (although the aftershocks of its attacks could be felt from 2 AU away) | Universe range | Immeasurable
Performance: FTL+ (took approximately 70 millions of kilometers before Kuzou even realized it) | Infinite speed (could exchange attacks with an universe-sized Liber Legis under a femtosecond; outgrew a universe) | Infinite speed (outgrew a universe)
Terrain: Ground, air and space, underwater | Super-dimension
Durability: At least planet level, regeneration makes it difficult to destroy | Universe level+ | Multiverse level due to its size
Material: Superalloy Adamantine /Hilocane | Unknown (described to have an incomprehensible super-logical structure even prior to Demonbane powering up)
Notable Features: Super strength, durability, speed, barriers, can perform impossible maneuvers by warping space-time and gravity via Timaeus and Critas, space-time breaking kick via Atlantis Strike, can trap the enemy in a barrier and annihilate it with infinite heat via Lemuria Impact, capable of sealing someone in another dimension | Same but much stronger with its power and size exponentially increasing without a limit, shapeshifting, regeneration (high-godly), flight via Shantak, fire and ice manipulation via Cthugha and Ithaqua, able to casually break space-time with normal attacks, can grab or restrain targets with energy threads via Atlach-Naacha, illusion creation via Mirror of Nitocris, time manipulation (in its all know forms) and causality manipulation via De Marginy's Clock, can generate temporal clones to attack, almost complete acausality, can exist even if it's reduced to nothingness (and continue fighting in abstract forms), able to create new universes and possible reality warping | Same as its previous form but far stronger with the possible ability to summon versions of itself from "impossible universes" (a.k.a. Klein Bottles that have already been destroyed)
Needed Prerequisite for Use: Having a powerful Grimoire to active it | Being Edgar
Gattai: With Aeon (to create Gunshin Kyoshuu/Mars Demonbane)
Special Forms: Mars Form (as pictured on the top)
Weaponry:

Base:
  • Timaeus and Critias (also the conductors of the Atlantis Strike)
  • Elder Sign
  • Scimitar of Barzai
  • Magic Gun
  • Lemuria Impact

Mars Version:
  • Timaeus and Critas
  • Magic Guns X 6 (for each hand)
  • Spell Helix X 3 (can be imbued with either Cthugha or Ithaqua)
  • Scimitar of Barzai x 6
  • Shantak
  • Elder Sign
  • Atlach-Naacha
  • Mirror of Nitocris
  • Lemuria Impact
  • De Marginy's Clock
  • Any random weapon and spell Edgar invented on the fly
Notable Attacks/Techniques:

- Atlantis Strike: Melee crushing spell that releases the energy of the leg shields to deliver a massive space-time breaking kick towards the enemy. The said attack had enough power that even its mere aftershock was able to shake a "Sea of Stars", most likely referring to the Asteroid Belt between Mars and Jupiter. Given that Demonbane just recently left the Earth, the distance was likely close to 2 whole Astronomical Units (300,000 km), making this feat even more impressive.
  • Atlantis Strike Vertex: Demonbane releases a series of consecutive space-time breaking kicks each with force comparable to the one described above.

- Lemuria Impact: Cor Leonis, Demonbane's main engine, activates and the machine's right arm emits a green glow. Following that Demonbane thursts out its palm, trapping the target in a barrier of space-time and gravity spewing forth from infinite multiverses. Following that the gravity is converted into heat, burning the target with infinite heat until it's completely annihilated.
  • Lemuria Dual Impact: Using the energies of both Cor Leonis and Heart of Infinity, Demonbane charges both of its palms with power. Following that the machine thurst its hands against the enemy, attempting to destroy the target even in case the enemy is capable of neutralizing a regular Lemuria Impact.

- Magic Guns: Mars Demonbane can summon 6 guns for its 6 arms, each firing homing magic bullets towards the enemy.

- Spell Helix: Demonbane summons 3 staff-like guns for each pair of its hands, elemental attacks powered by either Cthugha or Ithaqua
  • Spell Helix -- Spear Form: Demonbane transforms the Spell Helix into melee form, performing a close range attack powered by the Lemuria Impact. This technique was strong enough to bisect Mars Liber Legis.

- Shantak: Thanks to Al Azif's abilities Mars Demonbane is capable of unassisted flight.
  • Blade Wings: Mars Demonbane stacks up several Scimitars of Barzai, transforming Shantak into bladed wings to attack

- De Marginy's Clock: Mars Demonbane has the ability to manipulate time and causality to its likes, starting from just merely reversing time to outright stopping it, traveling through time and even outright destroying it. Supposedly, De Marginy's Clock also allowed Demonbane to create universes (albeit the novel isn't clear on that part).

- Size Increase: As the fight between the Mars versions of Demonbane and Liber Legis escalated, the world's binding energies grew weak. Abusing that both Demonbane and Liber Legis grew enormously, increasing both their size and power exponentially until the universe couldn't handle it and gave up. After strange eons of constant fighting the two Deus Machinas increased so much they outgrew the multiverse and ended up in a super-dimension where they could watch the fight of infinite Demonbanes from every possible and impossible universes.


Other: Not to be confused with the Zanma Taisei or Kishin Hishou counterpart and according to Master Therion they could go on forever and these stats aren't all-end yet, it still capable to level up more, if not, infinitely.

Important excerpt regarding Mars Demonbane's power, took from the final part of the novel Gunshin Kyoushuu Demonbane:

The two Deus Machinas bounced back, and started gathering power again.

As Liber Legis increased its size, Demonbane did the same. Both robots became much bigger, bigger, bigger, bigger….

When they clashed, the universe couldn’t handle the energy, but collapsed.

Next---,

They were in a huge universe. Even the two deus machina with enough force to destroy universe were less than a mere child. Avoiding robot particles that bounced off like billiard balls, the two men shot their powerful spells.

Next---,

They were in slow universe.

Here, flow of time was heavy as tar, so it was difficult for them to move even with time manipulation spell. They could clearly recognize when their techniques happens and moves. Defense and counter were easily achievable. There was no concept of reaction speed. Only perfect strategy like checkmate move could decide the outcome.

Next---,

They were in death universe.

Due to entropy being absolutely parallel, it was completely calm in time and space. In this world, nothing could happen. Matter couldn’t exist. Energy didn’t exist. Demonbane and Liber Legis couldn’t exist. They didn’t exist and act, but continued to fight in a way that beings from normal universe could not comprehend.

Then---,

The two machine gods changed size and shape, rebuilt spell structures, flew and ran through hundreds, thousands of worlds, and fought.
At one point, the two people swung thousand swords. At other point, they became bullets.
At certain point, they traded attacks in femto second(). At another point, they spent billions years to clash with imposing hits.
At one point, they vibrated dimension through clash of swords. At another time, they destroyed dimension with bombarding shells.
They accelerated, reversed, stopped or decimated flow of cause and effect, destroyed, created countless universes, painted the history over and clashed.
Next---,
Where they reached was beyond super time and super space, at the top of super dimension… super super space time continuum.
At there, Edgar and Al Azif watched.
Infinite universes popping like bubbles.
Inside infinite time loop like chain.
Infinite Demonbane fought, fought, and fought.
They were one of feasible possibilities.
They were one of chosen possibilities.
They were one of lost possibilities.
Infinitely intersecting and circulating like flow of blood, getting at one point. Infinite yet one fate, a part of it, yet entirety.
Entire eternal time, eternity beyond eternity. Infinite eternity chain…
Eternal evil cutting sword, DEMONBANE Athleta Aeternum fought, fought and fought.
And…
