Leslie is apathetic and, despite his youth, has the heart of an old curmudgeon with a stone-cold gaze. Stoic and calm, he has great negotiating skills and isn't easily moved. At first glance, he seems like another one of Corneo's obedient lackeys but he has a soft side to him. Leslie is often practical, direct, and cocky in his demeanor. He possess a dry, matter-of-fact method of discourse.
