Mother

Mother, a powerful war android known as a "Necromancer", who was reprogrammed to raise the human children on the virgin planet, Kepler-22b, in order to establish an atheist civilization. (wikipedia)

She has the ability to "weaponize" but only when she has her original eyes installed. She must remove them for fear of harming her children, but installs them when she needs to defend them from enemies. Without her eyes she is blind. She collects a few sets of eyes from other androids she has killed so that she can use when not wearing her original eyes.
