I would say that Sonic was inspired by Mario, but not directly based on it.

And there are quite a few similarities between Super Sonic and Super Saiyans
 * 1) Super Saiyan is a transformation that greatly increases the user's powers, a Super transformation is essentially the same.
 * 2) A Super Saiyan's hair becomes golden and spiked up during the transformation, during a Super transformation, Sonic (, Shadow and Silver)'s fur becomes golden and spiked up.
 * 3) A super Saiyan's eye colour changes to a turquoise colour, Sonic's did the same in Sonic 3, also in current continuity, a super transformation changes the user's eye colour to red
