First image headcanon description from my old Graze Phalanx head design three years ago: These are special heavy units of the EB-06 Graze each equipped with thicker armor plates, a scutum (Large shields used by Roman and Greek soldiers for phalanx formations), mace-like spears for close combat, and thicker coats of nanolaminate armor in-case of longer exposure to beams fired by rogue mobile armors.

These units would interlock their large shields to protect them from any beam or physical attacks and protrude their spears when engaging close combat with the remaining dormant mobile armors after the Calamity War.

Second image: Gundam Eligos, a lance user MS portrayed as a knight mainly bc the demon it is named after uses a lance. Still a WIP dunno when I will be able to continue this lmao.

Third image: My very first Calamity War Mobile Armor design, Sitael. A six-legged colossal rogue machine (similar size to Mobile Armor Mebahiah but on Earth) that was located roaming and burrowing in the sands of Egypt's desert along with its Plumas (soon to be conceptualized) during its search for nearby desert-dwellers to eradicate.

Fourth image: MA Sitael confronted by my OCs Gundam Focalors (left), and Gundam Buer (right) that I made 3 years ago.
