He is highly perceptive, intelligent and quick-witted while keeping a perpetually cool, slightly neutral or disinterested attitude. Jotaro's most noticeable trait is his seemingly aloof nature. He is a quiet individual, often satisfied with expressing himself in short phrases. he thinks anyone can tell his emotions just by looking at him so he thinks talking much more is a waste of time.
