Yes sonic has three brothers; Knuckles,Shadow and the third one i do not know the name of but know he is grey but not silver cuz hes from the future. Sonia and Manic are only sonics siblings in sonic underground in Pretty much every thing else sonic these are his brothers and as far as I know he doesnt have a sister
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.
no he's a different species sonic has siblings but there both hedgehogs
He has a brother named Manic the Hedgehog and a sister named Sonia the Hedgehog.
