ACF-S4xD/NU-010 Queen Caelestis

Technology and Combat Characteristics
Forged as the Magnum Opus of Samantha Jenkins, the Queen Caelestis is an amalgamation of the Solar Eclipse and Nexus' designs into a single machine. By using the body of an Insurrectionist Delta Type—one of the latest and most advanced mass-production units—both systems were integrated into the frame, and the Queen Caelestis was born.

Armaments
- Solar Cannon: (Virgo’s Flame) Due to the SCA’s original body being destroyed, the weapon was salvaged from the wreckage and promptly transported back to Guardia 7. When attached to the same frame as the Reflectors of the Nexus, it could only fire when any of the shields currently deployed were deactivated, as the power output put much strain on the Fusion Drive. Even with power conservation in mind, the SCA needed a secondary Fusion Drive and a Gyrotumbler mounted on its frame in order to function properly. At full power, the cannon can fire continuously for about seven seconds, with a three-minute recharge time. The beam is blue when fueled with Dechalus, orange with Ichor, and green with Arcandite.

- Reflectors System: While the Nexus' Core had been destroyed in the UNI's last stand, its shield Generators remained intact. Thus, it was promptly relocated back to Guardia 7 and combined with the SCA of the Solar Eclipse. It allows the machine to deploy high-durability hardlight shields, capable of deflecting projectiles five times better than a Nanolaminate Shield. Two of these Reflectors are located on each of the forearms and another pair on the calves, which can be combined to form a massive dome shield called the Magnificum Clypeus (upgraded Mind of AEGIS). Alternatively, they can be mounted on the shoulder VAPs, however this means they are only able to create the Clypeus.

- 40mm ASU: In the need the machine has to engage in combat, it is equipped with a standard assault rifle. While not the most effective for a machine of its class, it can still deal a considerable amount of damage when needed.

- Dopplehound 80mm Twin Gatling Cannon: This forearm or shoulder mounted weapon consists of a pair of six-barrel miniguns that deal moderate damage but have a high RoF. They can be used to stall enemy opponents, destroy delicate systems on enemy machines, and intercept approaching missiles or large objects. They are stored on the shoulder VAPs when in use.

- 100mm HAMGs: A medium-range Cannon that deals suppressive fire from a pair of barrels. They are mounted on the forearm or shoulder VAPs when in use.

History
Since Dom ignored Guardia 7 after his supposed elimination of the UNI, the TERRA System of the Nexus was left mostly unharmed and used alongside the SCA of the Solar Eclipse. With a combination of shield systems, basic guns, and a devastating final weapon, Sam served as the primary support unit when in combat with the rest of LEGACY Team. She uses the Caelestis as an honoring to her long-time partner in (technological) crime, Theodore Holland.

Trivia
- Do a thing where it’s shielding against a bunch of bullets by holding out its forearm shields, then sucks the shields back in and gets into its firing pose, blasting everything in front of it as the rest of the team charges forward.

- The sound of its Solar Cannon sounds like the Full Armor ZZ's Double-Beam Rifle from the animated clip thing. Click-BWAZZZZ—

- The combination of the cannon and shield are reminiscent of Guardia 7’s most iconic features. This was to represent the “soul” of the fortress.

The QC is technically a combination of four machines--The Enforcer MKII, TERRA, Cyclops Ground Type, and Insurrectionist Delta Type.

- One of its potential names, “Queen Caelestis,” translates to Queen of Life (Regina Caeli), which vaguely references Sam's character being based on the old personality of Regina LaMaris.
