Powers: The counterpart of the Invisible Woman, she can generate force fields, become invisible, and has some degree of superhuman strength.
Weaknesses: Unlike her Marvel Comics counterpart, Süskind cannot see without special goggles (created by Dowling) when she is invisible (consistent with physics, light passes right through her eyes.)
Bio: Süskind is Dowling's lover. She is described as the most dangerous of the Four, capable of instantly bursting people's heads. She is the daughter of a Nazi rocket scientist. Along with Randall, Süskind is killed in their meeting with Elijah.
Notes: Süskind may be named after real-life physicist Leonard Susskind, who is considered the father of String Theory (Ellis often uses themes of advanced and experimental physics in Planetary). Her physical appearance is apparently based on the X-files character Dana Scully.
