Ms. Fantastic's powers and abilities
Ms. Fantastic received her powers when cosmic rays bombarded her body. Susan somehow seems to tap into hyperspace when she uses her powers. As yet, the only limit seems to be her own reserve. She is reluctant to stretch her powers until absolutely necessary.
Invisibility: Ms. Fantastic has the mental ability to manipulate ambient cosmic energy for a variety of effects, including the rendering of herself and other objects invisible, and the construction of solid, invisible force fields. In an as yet unknown manner, cosmic energy interacts with the cells of her entire body in such a way as to produce a new form of energy with unusual properties. By a simple act of concentration, she can cause all wavelengths of visible, infrared, and ultraviolet light to bend around her without distortion. She also somehow directs enough non-distorted light to her eyes to retain her full range of vision while invisible. An observer, unaware of the peculiar path light takes around her body, would have the sensation of seeing through her. Susan can also mentally project the invisible energy produced within the cells of her body in order to render other people or objects invisible. The largest volume she can as yet turn invisible at a single time is approximately 40,000 cubic feet of volume (1,133 cubic meters), equivalent to a small swimming pool. She has sufficient control over her power that she can turn parts of her body selectively invisible. She is also able to make objects that have been turned invisible by other sources visible by letting her own energy projection interfere with that other method of invisibility. Further, she can make energy that is not in the visual portion of the electromagnetic spectrum visible by a similar interaction. Sue can also sense something made invisible by physical means (such as a machine) but not by magical or psionic means.
Blindness Inducement: By turning optic nerves invisible, Sue can make others temporarily blind.
Color Manipulation: Sue can also apply her ability to manipulate the interactions of light waves to seemingly change the color of objects, for example altering her hair color or turning the someone or something pink.
Psionic Force Fields: While the cells of Sue's body produce a certain energy manifestation, the cells of her brain produce a different, more potent manifestation. Through concentration, she is able to project a field of psionic force which she can manipulate into a number of relatively simple forms: rectangular planes, cylinders, globes, domes, cones, etc. The complexity of the shape is limited by her ability to imagine (mentally visualize) a particular form and keep it in sharp mental focus: not even she is able to see the forms she creates. The size of a given psionic force projection is also limited by her ability to imagine. The smallest force projection she can visualize (and maintain the visualization) is the size of a marble. The largest solid force projection she can visualize and maintain is about 100 feet in diameter. She can project larger force-objects if they are hollow. For instance, she could visualize and project a dome 1 foot thick about a mile in diameter (5,280 feet) and a dome 1 inch in thickness she can project for about 3.2 miles. Small objects at high speeds become missiles; large objects at slow speeds become rams. She can make these objects grow or shrink as desired.
Ms. Fantastic is able to use the projection of her psionic force to travel through the air. By projecting a rising column beneath her feet and simultaneously causing it to expand and topple at the same time, then creating another column that catches her, shrinks, and rights itself while then repeating the process, she is able to effect a zigzag flight path. She is able to reach an average speed of about 25 miles per hour, until she becomes fatigued by the concentration, after about 4 hours.
Sue's force fields have also prevented telekinesis from passing through them. When she uses a force field around herself it keeps the telepath's telekinesis from affecting her. When Sue puts a force field around the telepath, that telepath's telekinetic attack upon anyone in the immediate vicinity ceases.
Since her power is an extension of her mind and body, Susan is affected by inertial forces acting upon her projections. Thus if a car traveling at 60 miles per hour hit a wall of her force that was 6 inches thick, unless she generated a bracing shape against a sufficiently sturdy object, she would be affected as though she were hit by the car directly. Ms. Fantastic is able to control the surface of the fields rigidity to a certain extent. She can cause the surface of the field to be very hard, depending on its thickness (steel-like at about 2.5 feet), or as resilient as foam rubber. By making the field more resilient she is able to absorb more of the inertia of impacts within the field without having them transmitted to her body. She is also, through training, able to alter the shapes she creates while utilizing those shapes, often to absorb or deflect the force of impacts. When she creates objects of fields that are at the limit of her ability to mentally visualize, they tend to be resilient rather than rigid. Currently these fields can withstand impacts of Class 100 strength, a literally astronomical level. She is capable of generating and manipulating multiple psionic force fields simultaneously.
Shock Waves: Sue is capable of using her force fields as shock waves hitting her opponent with the force field capable of hurting Titania.
Cosmic Ray Awareness: Sue's retina are able to detect cosmic rays as well as visible light. This allows her to perceive her own force fields and other invisible objects and, with concentration, can also provide her with a limited form of vision, allowing her to "see" even if blinded.
Abilities:
Amateur Actress: Sue has some modest experience and ability in the field of acting.
Expert Sailor: Sue was a champion sailor as a youth, having already won major competitions by the time she was in her early teens.
Proficient Martial Artist: She is a capable unarmed combatant and regularly trains with the other members of her team. She underwent weeks of intensive training and became skilled in using bojutsu by manifesting an invisible staff for combat.
Ms. Fantastic's weaknesses
Concentration: The size, number, and movements of Susan's constructs are limited only by her powers of concentration. Once she stops concentrating on an object, it ceases to exist.
Sound Constructs: Sue's force fields are permeable to sound waves, thus Songbird was able to manifest a sound construct inside of the force field to knock her out.
