Give some suggestions then, other than the Tornado X [I think it is the orange biplane in Sonic 3].
Incorrect. The "X Tornado" was a transformation of the Tornado 2 in Sonic Adventure. Sonic 3 still had the Tornado 1.
And maybe he could use it as a final smash, but his overall attack set might be things seen in Sonic Battle. Like the extending glove or that arm cannon thing. And maybe he could use his tails as a weapon like in Sonic Adventure. And, of course, his down-special attack would be a spindash.
OT: Why the forget is Sonic's down and side specials the same damn thing? The side special should be a sort of dash thing like in SSF2.
