Rofl, what a waste it would be having shadow as a seperate character. Think about it, he is the same thing as sonic but black.
No.
Consider Sonic Battle. Their moves were nothing alike. Consider their personalities: again, there's nothing in common. Their motives? Completely different. To say that they're the same is like saying that Sakurai is the same thing as Bruce Lee but a game developer. Which would be racist.
Are you racist against Hedgehogs?
Do you drive around with an Eggman Empire flag on your pick-up truck, insisting to all of your friends that "The Egg will Rise Again"?
Do you wish that your pet dog had more cybernetic implants? I mean, like a
whole lot more?
Do you sit in your basement trying to make evil robots that look almost exactly like your most hated enemy?
You do, don't you? Yeah, I thought so. You're one of
those people.
