Silver is an anthropomorphic hedgehog, much like Sonic.

Silver is a kindhearted and well-meaning individual, driven by a strong sense of justice to right the wrongs of the past to uphold peace, though he is somewhat naïve and immature. Despite the monumental tasks he may have on hand, he is an optimist and will do whatever is required to protect the world.

Silver is best described as having "a strong sense of justice" and it is this personality trait that motivates him to head back into the past to correct the future. He believes in standing up for those who cannot stand up for themselves. This led him to accept Blaze when everybody else was teasing her for her pyrokinetic abilities. He makes alliances and rivalries very easily and takes people's word without question; this makes him easily tricked by others.

His voice should at least come close to sounding like either Pete Capella, Quinton Flynn, or Bryce Papenbrook.
