Mr. Delacroix, a character in The Sophomore series, is Sebastian Delacroix's dad and the CEO of Delacroix Development. He is first seen in Book 2, Chapter 6.


Dorian has blond hair, brown eyes, and fair skin. He wears a blue suit over a white dress shirt and a blue necktie with white dots.


Dorian is a ruthless businessman who doesn't hesitate trying to have Enrique Vasquez's old house condemned in order to make way for a mall he plans to build in the location. He also treats other people with contempt, such as remarking that Zack has a rather "histrionic proclivity" after the latter's complaints about Sebastian sabotaging the house boiler. He is also shown to use illegal means, such as bribing city officials, to get his way.

In The Junior, Book 1, it is show that Dorian has some sense of right and wrong, as he was shocked at the sadistic turn taken by Alpha Theta Mu's inner circle.
