Teccanic

The only demishade with an entirely metallic casing, the Teccanic sustains itself on an intake of minerals and metals broken down by its amorphous inner body, a chemical process which steadily generates electricity the creature can store in its many internal "batteries."
Channeling power through its powerful cable-like limbs, the Teccanic can generate enough heat to cut through or weld metal as needed, supply power to machinery or simply fry an attacker to a crisp.
The true inner body of the Teccanic is more fluid than most demishades. Portions of its matrix remain ambulatory for several seconds when detached from the main mass, and are extremely slippery to the touch.
The Teccanic has very poor mobility, but may scoot itself along on its tentacles, roll itself, or even ride currents of sewage from place to place.
