Shadow.
The brooding, cold, yet purposeful speed of Team Dark.He's got a great sense of pride about him, sometimes to his aid, and sometimes to his fault. Luckily, he has his teammates to steer him in the right direction whenever he's being too stubborn.
He remains unwavering in his promise to defend the people of Mobius, never forgetting the words of his dear friend Maria.
He fights and trains to remain at the top of his game and push beyond his own limits. In part due to his personal values, secondly to keep up to speed with his 'rival,' Sonic.
Although he seems to be a hard-headed loner in most cases, there are a select few capable of breaking through to him and getting him to open up. The years of teamwork with Rouge and Omega have caused him to soften up, ever so slightly.
