Sandra can create, shape and manipulate gravitation, a natural phenomenon by which all physical bodies attract each other, and gravitons, hypothetical elementary particles that mediate the force of gravitation.

She can bend gravity to make the environment very “heavy” or “light”, causing objects to “fall” toward another object instead of the earth (“nexus inducing”). She can repel and attract or move objects in a manner similar to telekinesis.

Offensive uses of this power include repulsing people or objects with such force as to cause them serious injury, increasing gravity to crush opponents, decreasing it to render them defenseless, or surrounding her body in a gravitational field to amplify her physical strength.

Defensive uses include creating a gravitational force-field to repel  all manner of attacks or anchoring herself to the ground.

She can also use her power to negate the effects of gravity on herself and propel herself at increasing speeds limited to her ability to shield her self from harm

(Present limits)
G-Force. Area effect only 100 feet from her self and no less than -8 G or greater than +10G
Telekinesis range line of sight Mass to not exceed 1,000 pounds
Amplification of physical strength not to exceed 5,000 pound lift or 1,500 pound throw
Force Field described as deflection and can deflect up to 50 cal. Rounds off trajectory but not energy attacks
Anchoring not to exceed 128,000 pounds and must be in contact with some surface.
(Warning if surface is incapable of supporting 128,000 pounds per square foot she will crush through)
Top flight speed 625 mph sub sonic
