Giantesses are imaginary, gigantic women. They are widely believed to be mythological by the humans of modern-day, since the term "giantess" is so generic, it seems possible to describe female giants not native to Earth which fall under the very forgiving criteria as giantesses. This includes the female giant: either a mythical being, such as the Amazons of Greek mythology, resembling a woman of superhuman size and strength or a human woman of exceptional stature, often the result of some medical or genetic abnormality.

Femforce is a comic book published by AC Comics that began publication in 1985, detailing the adventures of the titular team: the "Federal Emergency Missions Force" or "Femforce", some of them original creations, while others originated in the 1940s and 1950s, lapsing into the public domain by the time Femforce was published. The team are, as their name implies, all superheroines, and are the first and the longest running all-women 'super-team'. The series has passed 200 issues, a significant milestone for an independent comic book company. Writers on the book have included Bill Black, Stephanie Sanderson, Mark Heike, Paul Monsky, Enrico Teodorani and Francesca Paolucci. Artists on the book have included Bill Black, Stephanie Sanderson, Mark Heike, Brad Gorby, Jeff Austin, Dave Roberts and Rik Levins.
