On the surface, Roy seems to be a shallow and self-absorbed man, infamous among many of his colleagues and subordinates alike for the selfish and narcissistic aura he gives off. Easily as arrogant as his young protégé Edward, Colonel Mustang is wont to act in an ostentatious manner and appears to act mostly out of self-interest rather than any sort of philanthropy. He comes off to most as a sort of cocky layabout, shirking most of his duties and delegating his paperwork to subordinates while sitting idly at his desk with an amused smile on his face as he procrastinates, but quick to take action when it appears that there is glory and military notoriety to be gained.
