Ninjak is a fictional superhero appearing in eponymous American comic books published by Valiant Comics and Acclaim Comics. Co-created by writer Mark Moretti and artist Joe Quesada, the character first appeared in Bloodshot #6 as Colin King and quickly gained his own series. The Ninjak series was very popular and Ninjak #1 placed number one on Wizard Magazine's Top Ten Hottest Comics of the month article in February 1994. The lead character is ninja spy Ninjak, whose alter ego is British playboy Colin King. Ninjak immediately hit with readers, with the first issue selling close to 1 million copies. Ninjak has become one of the most popular Valiant characters continuing a long run and selling millions more copies to date. Ninjak comics have been translated into a number of languages including German, Italian, Spanish, Norwegian, Filipino, and Chinese among others.
A second series was produced after Valiant Comics was purchased by video game company Acclaim Entertainment in 1996. The second series was written by Kurt Busiek. In the series, a teenager is endowed with ancient ninja powers from a video game. He is able to become the game's hero, Ninjak, but finds that the twelve villains from the game have started appearing in the real world.
In the 2012 relaunch of the Valiant Universe, Ninjak first appeared in the second arc of X-O Manowar, initially as an enemy, but later an ally of the title character. Since November 2013 Ninjak has appeared in the series Unity, written by Matt Kindt. On October 6, 2014, it was announced that Ninjak would once again have his own series in 2015, also written by Kindt. The series' first issue was released in March of that year.
