TBH, I think to help him stand out, they might make Bandana Dee DEE first Kirby character to NOT have multiple jumps, and that they'll limit it to two. Also, I honesty can't decide just WHAT B.D.'s FS should be. Seriously, the cute little guy's just THAT unique. He's got more Final Smash options than you could shake a stick at! So far,, these are my ideas:
Megaton Punch - An even MORE OP version of the move form Kirby Super Star. Matter of fact, I would be so hype if THIS actually happened:
If not this, then I'd say make Megaton Punch his Down Special.
Waddle Dee Army - Essentially, he would inherit King Dedede's FS from Brawl, but much more usable, if that makes sense to anyone. Maybe with some Super Star (Ultra) enemies thrown into the mix.
Spear Rain- He would instantly summon EVERY Waddle Dee in King Dedede's army, and on his command, they would toss spears at EXTREMELY high speeds at opponents. BTW, I've always envisioned this to be in the style of Duck Hunt's FS.
Waddle Dee Tank - Bandana Dee would summon a Waddle Dee Tank from Scope Shot from RtD, hop inside it, and proceed to shoot down opponents.
BTW, look what I came across!
