For the sake of keeping major plot within the project, the name is being hidden. 

Another of the major protagonists, this role is a rough, but golden hearted young man in his late twenties. Raised on the streets of this vicious world, he may maintain a harsh exterior, one of threats and aggression, but he is just as afraid of life as the younger children he has taken in. Think of Fagin- if Fagin was hardly human, and even less stable. 

This is one of the most important roles of the project- and he is a character of clearly contrasting sides. One- the supposed rebel leader, an anarchist of ferocious independence, leading groups of Tainted to attack the upper classes and seek revenge. An intimidating, merciless figure of both hope and destruction, a construction of the world surrounding him- and no child to underestimate. 

The second- his true self. A sweet man, only trying to protect the only family he has left, caught in the tide of rebellion and revolution. A scapegoat for the masses. 

He is a very animated character, charismatic and comforting to those he cares to be so for. Using almost impressively colourful language, he acts as a father, and a brother, to the major cast, going as far as needed to save the people he loves. 

As a character, he is regularly is fights, so an actor interested in this role would need to be comfortable with the sounds needed- ie pained grunts, throwing punches etc. 

The only clear detail, beyond his personality, is his cockney (or similar) accent. It may be somewhat varied, and in no way cartoonish, but he is the most rough-and-ready sounding of the cast. 

Best of luck auditioning!
