Cervical Armor is inhumanly powerful armor, with equally powerful weapon schematics loaded into them. The armor itself is seen being equipped through a large syringe, that downloaded the data for the armor. When the armor is equipped by both Omega and Xero, the opponents that they are fighting are aware as to what the armor is, suggesting that it is a public project.

Cervical Armor is first seen in Xionic Madness 3 when it was stolen by Xero and Omega during their escape and is was used until the end of Xionic madness 4

Only Xero and Omega are seen with the armor, so it is unknown if Askad or Kary have Cervical armor upgrades.
