In 2014, Marvel announced that the king of Asgard would actually be a queen. The female Thor (who was still the star of the Mighty Thor comic as of May 2017) was an instant hit; the first five issues of her series outsold its predecessor by 30 percent.
In early 2015, Marvel announced the A-Force, an all-female hero lineup. Since then, She-Hulk and Co. have stepped into the vacuum left by the Avengers, who went AWOL during Marvel's Secret Wars storyline.
The A-Force storyline re-upped the tour of duty for classic super-heroines, but also introduced a new face: Singularity. Creator G. Willow Wilson described her as more of a cosmic event than a person, a pocket universe that chose to manifest in a human woman shape.
In a world filled with caped crusaders and psychotic antiheroes, the four women at the center of Image Comics' Rat Queens scratch a very neglected itch: that of fantasy geek girls.
Anyone who has played Dungeons & Dragons will recognize the classic team-up of the dwarven warrior, the halfling thief, the elven mage and the human shammy, but female readers will get an extra kick out of their combined girl power.
