Captain Toad Chance: 58%
He's in an almost identical situation to Bandanna Dee. Toad's are a huge part of the Mario series, putting
and
to shame in terms of importance to their franchise, but they haven't really done anything to make them really stand out. Then one steps up, puts on a headlamp and backpack, and BAM! New, important character to the Mario franchise! So far he's been in 4 games, one of which he was the protagonist. Combined with the fact that he's, well, a Toad, and I'd say his chances are pretty decent. Captain Toad's got a fanbase, he's got importance to his series, he's got relevance, he's got his own GAME, (Something that Rosalina and Jr. never got) and most importantly, he's a Mario character.
People try to claim that Mario is "overrepresented". Mario is the biggest gaming series on the planet, it has sold more then twice as much as most of the other represented series in Smash COMBINED. People recognize characters from the Mario series, those characters are some of the most famous in existence, it makes sense to add one as DLC. And out of the possible candidates, Captain Toad easily makes the most sense.
Even though I see him in a similar situation as Bandanna Dee, he's a bit lower because I don't think he'll be nearly as requested as Bandanna Dee on the Smash poll. For all I know that could be completely false, but based on what I've seen, the demand isn't as strong for Captain Toad as it is for Bandanna Dee.
Want: 90%
Again, for pretty much the same reason I want Bandana Dee, I want Captain Toad. He's got potential to be fun, I love the character, and Captain Toad is absolutely adorable.
