Two pictures squished into one to save space.

The egotistical supersonic wannabe is called Spike Zerox. And yeah you could probably beat him. He doesn't actually like fighting so this pic is OCC for him, but still pretty cool looking. ^_^

The girl Hedgehog is Petal Zerox. She's trying to catch Shadow's eye here because she's got a huge crush on him. Shadow doesn't even know she's alive so she's wasting her time XD
