X.A.N.A.'s spectres can pixelize normal humans when they possess their bodies. They become supernaturally powerful beings as modified by X.A.N.A. that are virtually impossible to defeat physically.
It manipulates their physical matter to transform them into spectral entities with many digital and electromagnetic related abilities. Their now spectral bodies make them virtually immune to harm, but when they get struck, their bodies are disrupted and reform after a brief moment. They have inhuman physical abilities like enhanced strength and speed, can levitate themselves to a degree, and also have electromagnetic powers that allow them to project lightning blasts and energy fields, levitate objects, and manipulating computers and electronic objects. Other powers include walking through walls, self-replication, and hypnosis through eye contact (Evolution).
Polymorphic spectres are also beings that have pixelated powers made by X.A.N.A.
Their only weakness is contact with electromagnetic waves, which disrupts the structure of their now pixelated bodies, but will eventually recover if the waves stop.
