Through out Sonic history Shadow the hedgehog and Amy Rose the hedgehog have always been Friends not a couple, though some Sonic couple Fan groups like: TailsxCream (Team/Cails,) SonicxAmy (Sonamy) oder even SilverxBlaze (Silvaze) etc, someone liked the couple ShadowxAmy (Shadamy) forwarding it world wide for Shadow and Amy crazed Fans to enjoy.

Youtube, Google images, Fanpop etc, all in some way give Shadamy Fans access to Shadamy things.

Artists such as Jazzybreal used to draw Shadamy related artwork one of Jazzy's peices include the banner of my Fanpop site
