Straight from palladia, these nanomachines take inspirations from the metallic armour of Efferbot! Being able to store, absorb, transfer, and use aetus, like a second layer of shell, It is also able to draw upon aetus from the user (which the user can then control through aetus puppeteering), to move, though telepathic control can still be maintained with only a minute amount of aetus as long as an alternative power source is suplied through the intake portal. Several capabilities of the Metalmites are the regulation of Aetus throughout the body, allowing for increased healing, replacing lost limbs, enhancing physical strength with their carbon fiber musculature, creating a protective metal glazing, forming blades and whips of metal, self-replication, aetus draining of enemies, and creating external solid metal structures by dis-attaching and superheating the metalmites. A gold coated variant is also available for aesthetics (or to create a portable miracle energy core)
