If you look at his abilities Shige is clearly Captain-class material, even if he lacks the stereotypical physical aspects of a Captain. He can bind demons, create vast and powerful illusions, has masterful control of Kido. The power of a character is determined by the scope of his or her abilities. Magic, and having such mastery as Shige does makes him Captain-class.

I would wager skill wise most Third Seats will not have abilities above expert level, and even then most of those will be ones the Shinigami specializes in. Just look at the Lieutenants, such as, or. Your character should be weaker than them as a start. Reiatsu probably is going to be higher than "High Spiritual Power" and they may or may not have Shikai. Ive seen lower seats with shikai but they were fairly limited in their scope at the time, so keep that mind. I'm already developing a character whose even weaker than a Third Seat; Vandheer Khushrenada.
