As a teenager, the boy known only as Boone was a friend of Dick Grayson, who would grow up to become Nightwing. As Grayson was learning under the tutelage of the heroic Batman, Boone was traveling throughout the Pacific Rim, learning martial arts from a number of teachers, including several former members of Ra's al Ghul's League of Assassins. In Hong Kong Boone encountered Shrike II, the "Master" that would turn him into a skilled and disciplined killing machine. Boone was part of the Vengeance Academy that Shrike II operated, training young teens to become assassins. Dick Grayson infiltrated the school, and formed a hesitant friendship with Boone. After Dick revealed the school to Batman, inadvertently causing the death of Shrike II, Boone swore to avenge his master. After meeting with Talia al Ghul, Boone continued his education by members of the League of Assassins. Taking on his mentor's name, this new Shrike became one of the world's foremost assassins, killing throughout Asia and the former Soviet bloc, before returning to America to become the new chief enforcer of criminal kingpin Blockbuster in order to assassinate Nightwing. He twice failed in this regard. Shrike later appeared, after the death of Ra's al Ghul, as a member of Nyssa al Ghul's new League of Assassins. Like his mentor and their namesake, the Shrike, Shrike uses a number of bladed and spiked weapons, such as swords, bladed tonfa, nets with fishing hooks added to them, and various knives and shuriken.
