Invisible Woman has primarily appeared in issues of "Fantastic Four". In issue 22 (January 1964), the creators expanded Sue's abilities, giving her the powers to render other objects and people invisible and create strong force fields and psionic blasts. Under John Byrne's authorship, Sue became more confident and assertive in her abilities, which became more versatile and impressive. She finds she can use her force field abilities to manipulate matter through the air, immobilize enemies, or administer long-range attacks. Susan changed her "nom de guerre" to Invisible Woman.
