Name: Nano-Celluloid Interface M Durin/Durindana/Durandal (according to direct translation it's called "Dourindana" but going by the naming customs of the other Nano-Celluloids it must be named after the legendary weapon Durandal)
Origin: Chrome Shelled Regios
Gender: Unknown/Not Applicable
Classification: Nano-Celluloid, Trans-Dimensional Horror, Anti-Mutant Countermeasure, Servant of Ignasis
Age: Unknown, at least many hundreds of years (much older than the Regios world)
Powers and Abilities: Super speed, strength, and durability, nanomachine that can exist in the Zero Realm, energy manipulation, can call down lightning strikes for self-defense, turns Aurora Particles into energy and then into matter to form a titanic body, shapeshifting, regeneration (High), dimensional travel, trans-dimensional senses, capacity to fight while its true body is hiding in the Zero Realm (albeit limiting its offensive potential), dimensional manipulation, minor spatial manipulation, high resistance to reality warping, can exist in a world without the concept of time (thus giving it resistance against most forms time manipulation, save for time travel and such indirect means)
Weaknesses: Durandal's core is a single microscopic nanomachine which is constantly on the move within the creature's body. Eliminating this nanomachine would effectively kill Durandal and wipe the remainder of its body to nothingness. Albeit accomplishing this feat is rather difficult without throughly vaporizing the entire creature.
Destructive Capacity: Island level+ with its lightning strikes, small planet level (3.5 to 17.5 zettatons) physically, suggested to be a planetbuster (said to have "destroyed the world", it also marginally overpowered Saya the creator of the Regios World, Durandal is also told to have been converting energy directly to compose its body, which would imply manipulating 100+ yottatons of energy yield)
Range: At least hundreds of kilometers, potentially tens of thousands of kilometers
Speed: Sub-relativistic (4000-9000 km/s,1.3-3% of the speed of light, albeit seems to be mostly immobile once manifested its full body)
Durability: Unknown for its dome, at least island level for its main body (can tank its own super-powered lightning bolts and use it to spread that around as a defensive measure), its size and limitless regeneration makes Durandal nearly impossible to defeat (you'd practically need to destroy Durandal's titanic body to the last microscopic nanomachine)
Lifting Strength: Class E due to its sheer size (this creature seems to be more than hundred kilmeters tall and wide with 10 heads almost as large as cities), possibly Class Z (said to have pulled the Earth into the Zero Realm)
Striking Strength: Class XJ (on its death Durandal spiraled up its body into a single point under a split-second before disappearing, it also previously moved its body from the Moon to the surface in seconds)
Stamina: Unlimited as long as it has connection to the Zero Domain for a steady flow of Aurora Particles
Standard Equipment: N/A
Intelligence: Durandal is an intelligent weapon. It possess good strategic sense and able to adapt to the situation quickly.
Notable Attacks/Techniques:

- Dome: As the beginning of its attack on Grendan, Durandal formed a huge dome around the entire city. It was 30 kilometers thick (or more, enough to bridge the distance between Grendan and Zuellni) and its true purpose was to chomp on Grendan like a piece of candy. Fortunately Saya formed a barrier around the city to prevent its immediate destruction.
  • Living Bullets: Once the initial attack deemed futile, Durandal opted for a different strategy. Barely overpowering Saya's space-warping barrier, it launched endless swarms of "living bullets", many thousands with each wave. These were actually giant containers filled with 20-30 skeleton-like insects. Individually they weren't a match for even a regular Military Artist, but their numbers were just stupendous.

- Lightning Strike: The dark clouds above Durandal are actually part of its body. They cover-up the portal to the Zero Domain and can discharge powerful lightning strikes for defense. Durandal can also conduct this lightning through its entire body, shocking anyone nearby.

Notable OBD Victories:

Notable OBD Losses:

Other: There's no official image on Durandal and the description of its appearance is somewhat vague. What we know that Durandal created a dome around Grendan which was as thick as the distance between Grendan and Zuellni. Said dome was like a mouth/flowerbud loosely attached to Durandal's much larger main body (which was huge enough to be seen like it's covering up the sky). Durandal's body also had elongated necks ending up in 10 heads with each being as large as a Filth Monster with a name (think of Behemoth here). The "M" in Durandal's name is a Roman number, implying the creature is the thousandth of the Nano-Celluloid series and canonically regarded as below both Harpe and Laevateinn in power.
