Story:The End of Eternity

The PAU/3G-RSXC-1006855 K106 Obsidian Prototype Model (nicknamed Kresnik) is a bipedal Power-Armored Unit seen in Rule of Cool, piloted mainly by the AN Coalition AU pilot Hero.

Overview
The Obsidian Prototype is a high-performance, pilot-syncing 3rd generation PAU developed and in use by the AN Coalition.

In terms of weaponry, the Obsidian is not exceedingly well-armed, leaning towards melee furnishings in its loadout. At its core, the Obsidian is a speed-focused AU, proving this with its lithe form and various modes of acceleration. There are the standard acceleration boosters in the soles of its feet, but there are also slots for this option in its shoulders, waist, and back, allowing for flexibility in movement and a high amount of speed. This focus, however, leads back to the relative slimness of the mech and its surprising light-weight, making the Obsidian not very durable at the cost of its high mobility.

The Obsidian has very few real weapons included in its stock loadout, most of them built for long-range hit and run tactics, but its pilot is one famously devoted to melee combat, so a long blade made of the same armor as the hull itself is included on the hip of the mech. This is a controversial decision, having an armored blade, because it is not the sharpest and is susceptible to breaking, as well as not being as portable as beam weapons. However, the armor allows it a large amount of power, and while not as precise as beam weapons, it is very useful in stopping other mechs and even mobile armors or battleships.

The Obsidian mostly relies on the orthodox operating system utilized in 3rd Generation AUs in that it synchronizes with the pilot's mind in order to allow quick decisions and augmented battle capabilities. However, the Obsidian in particular among the other prototypes touches heavily on previous operating systems. Its main mode of control is an unprecedented of Gen 1 manual control and Gen 2 systematic commands, making it a bit redundant with Gen 3's psychological control. Although both methods are indeed possible, using them both at the same time is unwieldy of not unproductive. While the preferred use of the system depends on the pilot (notable user Hero relies on the old system mostly, but this could stem from his experience with Gen 2 units), this synthesis of an operating system provides much more mental stability and safety for the pilot than other Gen 3 Prototypes.

Specifications and Combat Characteristics
The 3G-106 armor is made of reinforced Crystanium armor, and boasts a startling amount of rocket accelerators in its frame, yet despite this the AU has a surprisingly light weight. Its armor is a dark blue with light blue, almost silver highlights.

Armaments

 * Crystarium Enforced Blade: A standard-length blade that is made out of the same armor that the AU is fitted with. This lends it a level of unique power, but is somewhat heavy and thus removes the possibility of the unit equipping more blades and keeping its mobility. Because of its armor, it is not the sharpest blade and can be inaccurate, especially when compared to standard issue beam rifles, but can be quite powerful against other AUs and even battleships.
 * MU-86G 60mm Vulcan Gun: A default vulcan gun equipped in the head and arms of the AU. While it can normally do little damage against the armor of an AU, it serves as a much more efficient and cost-effective means to shoot down incoming missiles, as opposed to using the plasma rifle, the power of which would be overkill and is far more limited in ammunition. Also, the vulcan guns were designed to be used against small, lightly-armored targets such as ground combat vehicles or attack helicopters.
 * XBR-7482 Plasma Rifle: The standard plasma rifle included with most AUs. Sacrifices heavy firepower for portability and a small size, but it still holds enough power to cause considerable environmental damage or destroy a fellow AU unit. Runs mostly off a self-sufficient plasma cell that can be reloaded. In dire situations, it can run off EN Drive power, but this is very dangerous and cause explosion of the weapon.

Special Features

 * EN Drive: Full name Electromagnonuclear Nucleus Drive, the EN Drive is the main power source for the Obsidian and for most Gen 3 AUs. It is a semi-perpetual generator that is scaled for use and storage in the torso of the unit. It manipulates an isolated nuclear reaction to produce enough energy for the unit to function and singlehandedly emits the particles needed to catalyze rocket acceleration and thrust. So long as it isn't pushed to breaking limits or exposed to extreme temperatures, the EN Drive has the potential to be efficient for an almost indefinite amount of time, but the nuclear catalysts in its core must be replaced quite frequently or its efficiency will slow to a crawl, seriously hindering the abilities of its equipped mech.
 * Pilot Synchronization System: The all-encompassing Gen 3 AU sync system. As with any AU, the operating system and computer interface beneath the unit is extensive and must be mastered for use, but Gen 3s require all pilots to be directly linked to the interface and operating system of the AU, allowing unprecedented levels of quick reactions and notable observations in the field of battle. Although this can prove extremely harmful in the event of damage to the mech, the earlier mentioned hybrid control system removes some of this risk in piloting the Obsidian.
