Spectres usually pixelize normal humans by possessing their bodies. They become electronic energy beings made into X.A.N.A.'s likeness. It can also do the same thing to some animals (wolves, crows, etc.), and certain non-living objects.
They become entities that have supernatural powers. Their now spectral bodies make them virtually immortal, but when they get struck, their bodies are disrupted and reform after a brief moment. They are given inhuman physical abilities, and levitation to a degree. They can also manipulate electrical energy in ways that allow them to project blasts, affect minds, move objects through magnetism, and influence technology from close distances. Advanced powers include walking through walls, self-replication, and hypnosis through eye contact.
Polymorphic spectres are pixelized beings morphed from spectres to imitate human appearances, with also having types that can change their appearances at will, making them more ideal for infiltration.
Their only weakness is contact with electromagnetic waves, which disrupts their bodies' molecular structures, but will eventually recover if the waves stop.
