After the exposure to the energies of the Cosmic Cube, the Aquarian's body generated a field around his body that nullified nearly all forms of energy (kinetic, electrical, magnetic, gamma, gravitational, etc.) that are higher than a certain preset level, which he calls his "null field". For example, a bullet contains a level of kinetic energy higher than what his Null field will allow for, so once the bullet enters his field, its energy is nullified. His own body is subject to this field, and he cannot move any faster than it will allow. This field naturally resides five feet from his body, and he cannot disable it; it is active at all times regardless of whether he is conscious or not. With concentration, however, he can contract this field to within five inches (127 mm), or expand it to .
