No, they are not related. Shadow was created by a relative to Dr. Eggman.
no,silver is not sonic's cousin because he's from the future
yes sonic is in shadow the hedgehog you meet him on the way
Sonic the hedgehog and Shadow the hedgehog. are not related because sonic was born by his missing Mother in the series Sonic Underground, they only shown Sonia(Sonics Sister) and Manic (Sonics Brother) but that does not solve the cousin part. If Shadow were their cousin he would be in Sonic Underground, again and again. And for Shadow's part in the Video Game Sonic Heroes (Created by Sonic Team and SEGA) there were about 100 clones of Shadow, all by Dr.Eggman. so he was actually the father sympathetically. And Eggman and Sonic have no family relationship whatsoever.So that concludes it, Shadow is NOT Sonics cousin. Thanks For Asking!
