Mario Onyx: Ultimate Pro Bono Lawyer 

Age: 21 

Gender: Male 

Mario Oynx is the half brother to Cepla Onyx and is the illegitimate heir to the Onyx family mining operations.

Mario is currently working as a lawyer with the Hope's Peace foundation, which helps innocent people locked up in prison appeal their cases for no charge at all. Mario is a little justice hungry overall, and will not stop under people pay the price for their past actions, meaning any killer would have to face his frenzy. While investigating or learning, he enters a flow state and all of his wit and charm is replaced with cold, calculated speak. He will be only be focused on judgment, plain and simple. He seems like a completely different person than the goofball he is most of the time. 

When asked about his father, he is tight-lipped but speaks niceties about him and his sister. Who knows what he really thinks.  

Mario has a medium-high pitched voice, think like an anime protagonist almost. When he is in the flow, he is more Miles Edgeworth in tone.
