Will Sliney is an Irish comic books artist.
 He is known for his work on comic books such as the "Marvel's Fearless Defenders " series as well as the best selling graphic novel "Celtic Warrior: The Legend of Cú Chulainn".
 He may be best known for his work on "Spider-Man 2099".
The Red Tornado is a fictional character, a superheroine in the DC Comics Universe, debuting during the Golden Age of Comic Books.
 Created by Sheldon Mayer, she first appeared in her civilian identity as Abigail Mathilda "Ma" Hunkel in All-American Publications' "All-American Comics" #3 (June 1939), and became the Red Tornado in "All-American Comics" #20 (Nov. 1940).
 As the Red Tornado, she was one of the first superhero parodies, as well as one of the first female superheroes (possibly the very first), and, when occasionally disguised as a man, comics' first cross-dressing heroine.
 (Madame Fatal, earlier that year, was the first cross-dressing hero.)
The Valkyrior is a fictional organization that appears in American comic books published by Marvel Comics.
 Based on the Valkyries of Norse mythology, the group, created by Stan Lee and Jack Kirby, first appeared in "Thor" #133 (October 1966).
 Within the context of Marvel's shared universe, the Valkyrior is a group of female warriors led by Brunnhilde / Valkyrie that was originally designated by Odin to bring the souls of slain heroes to Valhalla.
 In 2013, the team became the subject of the short lived series, "The Fearless Defenders".
The Hawkeye Initiative is a satirical Tumblr page similar to Women in Refrigerators that comments on the depiction and treatment of female characters and superheroes in comic books.
 The site features fan art of Marvel character Hawkeye in various poses held by female characters that the artists believe to be impossible or sexually provocative.
 The site's intent is phrased as "to draw attention to how deformed, hypersexualized, and unrealistically dressed women are drawn in comics".
 The site further states that these poses are seen as normal and go unnoticed by many readers when performed by female superheroes.
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 public domain by the time "Femforce" was published.
 The team are, as their name implies, all female superheroes, and are the first and the longest running all-women 'super-team'.
 The series has passed 150 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 and Rik Levins.
The Champions are a fictional team of superheroes appearing in American comic books published by Marvel Comics.
 The team first appears in "The Champions" #1 (October 1975) and was created by writer Tony Isabella and artist Don Heck.
 Their titular series is regarded as the quintessential example of a failed superteam comic, suffering from constant turnover in the writers and artists working on the series, lack of a consistent direction or concept, sporadic publication, and mediocre sales.
Misty Knight is a fictional character appearing in American comic books published by Marvel Comics.
 Created by Tony Isabella and Arvell Jones, Knight was first mentioned (by name) in "Marvel Premiere" #20 (January 1975) and appeared in the next issue.
Black Lightning (real name Jefferson Pierce) is a fictional superhero appearing in American comic books published by DC Comics.
 The character was one of the first major African American superheroes to appear in DC Comics.
 He debuted in "Black Lightning" #1 (April 1977), and was created by writer Tony Isabella with artist Trevor Von Eeden.
The Fearless Defenders was an ongoing comic book series published by Marvel Comics that debuted in February 2013 as part of the company's Marvel NOW!
 initiative.
 The series, written by Cullen Bunn with artwork by Will Sliney, centered on the Valkyrior, a team of female superheroes led by Valkyrie and Misty Knight.
 Despite favorable reviews from critics, the series ended in December 2013 after thirteen issues due to poor sales.
Nelvana of the Northern Lights is a Canadian comic book character and the first Canadian national superhero, debuting in Hillborough Studios' "Triumph-Adventure Comics" #1 (Aug. 1941).
 She is also one of the first female superheroes, debuting before Wonder Woman but after Fantomah, the Golden Age Black Widow, Invisible Scarlet O'Neil and others introduced in 1940.
 Nelvana of the Northern Lights is Canada’s first distinctly Canadian female superhero.
