As a businessman, as well as a smuggler, Dobo often displayed a high degree of pragmatism. While his brother, Dendis, was an idealist who insisted on doing business in a strictly legitimate fashion, Samhan bore no scruples at all, dealing with anyone who could bring more credits his way. As a result, the two brothers had an antagonistic relationship and would even argue with each other in front of a customer. He was also known to be irritable, argumentative and vindictive; when he was arrested by the TSF, he swore vengeance upon those who had set him up, including the Exile.
