Anna Mercury is an American creator-owned comic book series created by writer Warren Ellis and artist Facundo Percio.

Ellis compared the character to a mix of Daredevil, Lara Croft and a character from Crouching Tiger, Hidden Dragon, also noting the influence of science fiction pulp magazines[1] and the Lensman series.

[2] The writer had first worked with Percio on Ellis' webcomic FreakAngels, noting that he loved the fusion of European-style illustration with Anglo-American comics.

Anna's travels through the space between worlds charges her equipment that lets her defy gravity, move through solid objects, and perform other feats, though the energy is limited and must be monitored closely.

[4] Rich Johnston was positive about the first issue of Anna Mercury 2 in a review for Bleeding Cool: "It's big, it's bold and it's brash but it also has the depth and background and even occasional tenderness of the likes of Planetary".
