Boone harbors a long standing enmity for Dick Grayson dating back to their youth, when the two shared a friendship that was in many ways doomed from its inception. While Grayson served as the Batman's partner Robin, the boy who would be known as the predatory Shrike traved alone throughout the Pacific Rim, gleaning an array of martial arts skills both from a variety of unsavory teachers, including several former operatives of insidious League of Assassins. In the back streets of Hong Kong, Shrike met the "Master" who would forge the already hardened youth into a disciplined killing machine, undertaking contract eliminations throughout Asia and the former Soviet bloc-and never once failing to make a kill.[1]



His preferred weapons include shuriken and steel reinforced tonfa, which Shrike has customized with retractable hooked blades.
