she also has the psionic ability to manipulate ambient cosmic energy to produce psionic force in relatively simple forms (rectangular planes, globes, cylinders, cones, domes, etc.). She can mentally generate and project force fields of tremendous strength, which she manipulates for a variety of effects. The fields are able to repel solid objects, even those of great mass and momentum, and can repel all but the very strongest energy attacks. She can generate these fields at a distance of several hundred feet. It has never been specified whether her fields are related to gravity, to electromagnetism, or to some other fundamental force, but Nathaniel Richards theorized it came from Hyperspace. It may be the case that her invisibility and her force fields are two aspects of the same power, although the precise manner in which these aspects are related is not clear

Sue can shape her force fields into invisible 'constructs,' usually simple shapes such as barriers, columns, cones, cylinders, darts, discs, domes, platforms, rams, ramps, slides, and spheres, though in other situations she has created more complex shapes such as a sword and offensive grappling hook. By forming one of her force fields within an object and expanding the field, Sue can cause the object to explode. She can also simulate telekinesis, by projecting her energy into a beam out of her hand that connects to the object or victim, and can manipulate the field to move it around.

She can also travel atop constructs such as ramps, stairs, slides, columns, and stepping discs, enabling her to simulate a limited approximation of levitation or 'flight.' She is capable of generating and manipulating multiple force fields simultaneously. This power is only limited by her concentration; once she stops concentrating on a field, it immediately ceases to exist.

Invisible Woman (arguably) the most powerful member of the Fantastic Four and one of the most powerful Marvel characters, and their deadliest enemy Doctor Doom has commented on many occasions that Sue is the most dangerous of the foursome.
