Shadow could be a semi-clone, with at least one new attack. Maybe chaos spear replacing his B+forward roll, and he could use chaos control as a recovery teleport move instead of the spring.

I like Windy Hill, and frankly it does offer more platforms, and places to fight then Green Hill, as it’s a bit bigger, and has a nice curve like the Super Mario Galaxy level does.
The only interesting thing about Green Hill is the breakable ground, as honestly it’s a pretty flat level, just with a curve in the middle. (I always thought it’d be better if you could jump up on top of the shuttle-loop, or have buzzbomber badniks fly around occasionally trying to zap you, and you can break them, revealing a trapped animal that scampers away.)

I actually am thankful. because I always worried they were going to remove Sonic, due to the backlash back when he was first put in Brawl. (Yeah, there was some backlash back then.) Not to mention, Sonic’s not very popular in Japan.
