ESU-S4xA/NU-017 Onyx Repair

Technology and Combat Characteristics
With much of the Onyx's equipment being barely functional, Ian directed the machine's overhaul from the ground up. With its main focus being in high-mobility, he would keep the machine's equipment set minimal (apart from the arms, where much of its weaponry is mounted), while the rest of its frame was given a multitude of extra thrusters and improved joints to make its movement even more dynamic in nature. In the end, the Onyx Repair was born from the manic design of the Onyx, representing Ian's inheritance and revision of the Mercury Legion's principles.

Armaments
- Guards Assembly: A multipurpose forearm attachment that is actually a combination of three different weapons—A Stingblade, Breaker Shield, and 40mm Gatling Cannon. The whole assembly can be purged at will. The only weapons capable of use after a purge are the Stingblades.

- Multi-Functional Stingblades: The OR is equipped with a pair of Customized Anti-Armor Blades that were salvaged from the original Diamondback's own Stingblades. They are mounted on each of the Forearm Armors, and are usually covered by the Breaker Shields as well. When deployed, the blades flip forward on a swivel joint, or can even half-rotate in order to be grabbed by each of the Unit's hands. Similar to the Sabre’s Waraxes, Ian customized each of these blades with his own designs, using the words “Duty” and “Salvation.”

- Breaker Shields: Each forearm has a medium-sized shield used for blocking and guarding the Stingblades when not in use. Both shields have a spiked knuckle mounted on the front for punching attacks (and when the blades are stored away or destroyed). If need be, the shields and swords can be purged, breaking off of the forearm. (Custom version of the Nanolaminate Compact Shield)

- 40mm Gatling Cannons: A pair of Gatling Cannons stored under the Breaker Shields, above the MF-Stingblades. They can provide medium-range fire and can be purged with the rest of the shield assembly when needed.

- Shoulder Swarmfire Missile Launchers: Similar to the original Diamondback, the Onyx is equipped with a pair of shoulder mounted 25-missile silos, capable of enveloping an enemy in a fiery blast. When deployed, the blast doors of the silos slide open, allowing for firing of the weapon. They were developed using blueprint data from the Diamondback’s shoulder armor.

Special Equipment and Features
- FrameBreaker Visor: A prototype Targeting System that detects and highlights the unique metals of Garrisai Frames in an infrared light. This allows for the Onyx to specifically attack the joints and exposed armor plates of enemy Garrisai, making it a extremely deadly force. The only flaw in this system is that all other visual abilities are impaired, thus causing tunnel vision for the pilot in combat.

History
As sympathy for Ian’s loss of his leader, he was gifted the Onyx which had been repaired with parts retrofitted from the Sabre. It was eventually outfitted with equipment chosen from Ian’s specifications. In retrospect, it had to have been the fastest unit to have ever been developed, followed by the Silver Magnum and Archangel.

Ian used the Onyx Repair during the final battle, fighting valiantly until he was incapacitated by the Silver Magnum. After the battle, the OR was recovered and put back into storage in honor of Jack Kendall.

Trivia
- Notes And Trivia: Do that cool thing where both blades rotate their handles outwards and he crosses his arms and grabs both, swinging them out.

- The Onyx Repair’s forearm attachments (40mm GCs) are inspired from the weapons used by Veb’s Mech in EYC. The concept of the Diamondback itself can be traced back to continued redesigns of the infamous machine.

- The weapons layout of the forearms also are reminiscent of the Gouf Custom's from 08th MS Team.
