5 Ronin Deadpool is #5 issue in a five-issue weekly-shipping limited series, written by Peter Milligan and drawn by Leandro Fernandez, out in March from Marvel.
Although is last cover of the serie, is second one I did. Main idea was to show a classic ronin shot showcasing Deadpool's dual characteristics, someone was once a noble samurai driven insane by betrayal and war.
This is final cover sketch.
