The title character is a gun-for-hire freelance anti-terrorist, who is brought in when things go horribly, horribly wrong, and who uses extremely violent methods to achieve his goals. However, he is also an active social liberal who takes part in anti-war demonstrations, and is internally conflicted about the measures he has to take.
Originally solicited as an ongoing series, Jack Cross unfortunately stalled after the first story arc of four issues. Although a mention of a further eight finished scripts (and plots for twelve more issues) was posted on various forums the scripts were incomplete (requiring further dialoguing) and the book was placed on hiatus after the fourth issue. Later on, Ellis posted on his MySpace page that there will be "No more Jack Cross for DC".
