Ivan Milat, also known as the "Backpacker Murderer," was a notorious serial killer and abuser operating in the Blue Mountains region of New South Wales, Australia, during the late 1980s and early 1990s. He targeted young tourists, hitchhikers, and backpackers who had traveled to the area, luring them into his clutches with promises of shelter and security. Once his victims were in his grasp, Milat would kill them in a brutal and ruthless manner, often leaving their bodies in the surrounding woods and wilderness. In 2025, Ivan Milat was resurrected and joined ISG. He also developed a strong interest in firearms, becoming a gun fanatic. He could often be seen practicing with various weapons and firearms.
