You can't in a normal level. When you unlock the final level, you are Super Sonic in that level.
If you put in Sonic 2, you get Knuckles in Sonic 2.If you put in Sonic 3, you get Sonic 3 & Knuckles.If you put in Sonic 1 or Sonic Classic 3-in-1, you get all levels of Blue Sphere (Press A+B+C on No Way screen).If you put in any game other than those listed, you will get one level of Blue Sphere (but not all games work).

in his last level you have to jump onto a rail that is slightly of the normal path
You battle a genie.

Sadly, like every game since Sonic Adventure, you can play as Super Sonic ONLY in the Last Story.
You can't become Super Sonic without going to the last stage, unless you hack the game.
Finish Sky Canyon level as Sonic.

If you mean Sonic Riders 2,then it's the Rainbow Board.
"Sayonara, Shadow the Hedgehog"
probaly sonic and the dark knight.but they could make sonic next gen 2
if you enter the bonus round on the last level and get the jem at the end
you have to get all of chaos emeralds and beat all stories. P.S It is a boss that you face not a level
