Spinnerette puts the whammy on Reed Richards in Fantastic Four #237.
Equilibrium distortion is a super-power that affects the equilibrium of an intended target, causing them to lose balance, and in some cases, great pain. This is an effective means of combat, as it makes the target more vulnerable to attack. This ability may also be reflected in some chemical agents or in some technological devices such as the Sonigun used by the DC Comics super-villain, Sonar. Another comic book character who possesses this ability is the Marvel Comics female villain, Vertigo.
