Aaron

Aaron is an easygoing dog. In the possession of Keith and his group, he was trained as an aggressive fighter as well as an effective tracker and bomb dog. He was brave enough to attack Loid Forger, who was shooting at him, and charged at him head-on. Despite that, he was genuinely scared by the angry Yor who defended Anya from him and Keith, and this was enough to escape from his then-owner. A noticeable difference between Aaron's current friendly side and his former aggressive behavior Following his capture by WISE and subsequent adoption by Sylvia, Aaron's demeanor softens considerably. He becomes friendly and playful, showing no lingering aggression toward those he previously targeted. Aaron is also highly emotional and reactive, expressing visible displeasure when Sylvia leaves their apartment untidy, when Bond fails to recognize him, or when he learns that his name was chosen casually rather than with intent. Like Bond, Aaron is a mentally enhanced dog as a result of Project Apple, exhibiting heightened intelligence and awareness. Unlike Bond, however, he is less absent-minded and more attentive to his surroundings. At times, Aaron shows erratic or overly excitable behavior, which Sylvia manages through food and positive reinforcement, a method that consistently calms him.

Aaron is a large male German Shepherd. He has a domed forehead, a long square-cut muzzle with strong jaws, and a black nose. His eyes are medium-sized and yellow, and his ears are large and stand erect, open at the front and parallel. Aaron's coat is tan and black, and he has a typical black mask and black body marking in the form of a "saddle" on his back, characteristic of his breed.
