The last answer was not that helpful. Sonic and/or Silver the Hedgehog are not related. In the show, Sonic Underground, Sonic's had only 1 brother and only 1 sister. His brother was Manic and his sister was Sonia. Sonic does not have any more siblings. Silver is just a hedgehog from the future, not Sonic's brother.
