Nice but.....
It would deserve a ten if stupid gay ass Mario hadn't won, I'm talking in reality here, because look: Mario kills things by jumping on them, and even if one blow from that or from a fire flower or whatever could kill Sonic, then it still wouldn't work, because of these two things: Sonic's razor spin could really instantly kill Mario (or anything else) if he got that close to his blades, plus he is TOO fast, Mario is a big fatass who with great lard jumps on things and squishes them to death, Sonic is a super speed hedgehog who can fo into super form.
