Ah, interesteing.

Also, it was Naoto Oshima who designed him, with Yuji Naka taking over everything later on. But that was most likely before Shadow (and eventually) Silver came on the scene when the team had to decide to design up new hedgehog characters.

Although we can see that Amy has biege colored arms like Sonic, is it possible she also has a biege-colored chest like him too? A lot of fan artists suggests that she does but no one has actually really seen in the official series, what with the clothes and all. I expect she should too.

In this case we can confirm that they are part of the same in-universe hedgehog sub species of some kind which differs from Shadow and Silver.
