I haven't heard of Amy Adams, but I know of sonic the hedgehog, so I think sonic is more famous.
It is very obvious that Shadow is male.
We all know that Jaden Smith is a cool actor but, unfortunatly Sonic is known more. 3/8 of Americans know Sonic while 1/8 know Jaden. :(
Yellow Hedgehog? Well, you know there is a white hedgehog and that he's Sliver the Hedgehog! Unfortunately, he is sliver in color. Sorry. Also that you must be mistaken with Super Sonic as in the Yellow Hedgehog but that's only in his super transformation. So most likely, there is no Sonic character that, I know of, is a Yellow Hedgehog. Accept my apologies, senior.
