Making the study of herself and her three partners her new life's work, Sue spent months investigating their abilities and charting their powers while improving her own understanding of herself. She has deduced the nature of both Reed and Johnny's changes, though her own powers remain unexplained and she is unable to penetrate Ben's skin to determine any more detail than his internal fluid pressure. Sue continues to develop her control of her force fields, using them to create pressurized environments at the bottom of the sea, plugging her own throat to prevent swallowing poison gas, and creating "cushions" to catch falling people and objects. Damage to her force fields also causes her mental strain or, in extreme cases ("Ultimate Power" #5), to black out.
