Basil appears to be a very scary man at first, with his rough appearance and stern expressions. Despite this, he is actually a very gentle and kind man. He suffers pretty low self-confidence and is incredibly shy, so he prefers to avoid social situations when he can. Asmo does the talking and planning for both of them, while Basil in turn acts as his voice of reason and keeps him anchored as best as he can. This, obviously, isn't an easy task, and he's very easily swayed by his brother into doing stupid things.

He's a good uncle to Sif, and tends to understand her emotions better than Asmo at times. He's tried to mellow out on his criminal activites in order to offer her a SOMEWHAT normal upbringing, but honestly he's just better at hiding it now. Being the muscle of the group, he'll always protect his family without question, although it's usually unneeded.
