Well, in Dark Shirou Emiya fanfiction, the theme of identity is quite common. Since he has changed from the original Shirou, he often struggles with who he is now. The theme of isolation is also there. His dark nature may make him an outcast, and he has to deal with being alone. And then there's the theme of vengeance. Sometimes his actions are driven by a desire to get back at those who he believes wronged him in his past as Shirou. These themes often interact with each other, for example, his search for identity can be influenced by his need for redemption.
One common theme is the struggle between good and evil within himself. Another is redemption, as he tries to atone for his dark actions. Power and its corrupting influence is also a frequent theme.
