By disrupting the electrical fields of machinery, Phantazia could short them out completely, or control them to some degree; opening computer-locked doors, jamming weapon and targeting systems, etc. Phantazia was able to disrupt the bioelectric energy fields and nervous systems of other living beings as well, resulting in pain, paralysis, loss of physical coordination, and in the case of superhumans, the inability to control their powers, causing them to fluctuate in strength, cease functioning altogether, or spew out uncontrollably. She has, for example, disrupted the blast field of Cannonball, making him vulnerable, and also caused the superhero Sleepwalker to temporarily lose control of his reality-warping ability.
