User blog:KnucklesFanGremlin/Am I the only one who's ever wondered this?

So I was browsing the wiki again, and I eventually just got bored and looked at the background of the page. Then when I looked at the silhouette characters, I began to wonder...

WHO THE HECK ARE THEY?! Seriously, does anyone know who the silhouette characters are!? They look like they would be really cool characters, but no one's ever mentioned them because they're silhouettes in the background picture.

I especially want to know who the character at the bottom left is, they look like they would be cool...
