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, Silver and Sonic are not related in any way.
yes i saw a sonic underground sonic plush on ebay.
Sonic underground is a version of sonic in the underground dimension the other Sonic of Sonic X is from the Sonic X dimension check Sonic (disambiguation) Mobius encyclopeadia
The duration of Sonic Underground is -1320.0 seconds.
silver sonic is just hyper sonic after about 5 minutes.Isn't silver sonic a robot you fight on sonic 2?
Sonic Underground isn't even a real game. Anyway, you spell the name like Manic. Real stupid once again. SONIC, SHADOW and SILVER are the brothers.
There were two Sonic shows before Underground: The Adventures of Sonic the Hedgehog (AoStH) and Sonic the Hedgehog (SatAM). SatAM was similar in setting to Underground. There was also a film, entitled Sonic the Hedgehog The Movie (Sonic OVA).
Four. Adventures of the Sonic the Hedgehog Sonic SatAM Sonic Underground Sonic X
he is sonic brother in sonic underground
Shadow has no parents as he is an artificial lifeform. Sonic's parents are unheard of in the games and they are robotized in SatAM, Sonic Underground and Archie. And Silver mentions his parents in Sonic '06 ("This world was devastated before I was born")
They only appear in sonic underground
