DISCLAIMER: A rigorous method was not used to achieve these results.
2nd DISCLAIMER: I advise against interpreting these results as a measure of true character potential. Instead, see them as a a reflection of the early meta, or at the very least as a picture of the semi-competitive communities' thoughts on the early meta.

The Method
The method I used to gather/aggregate the data was as follows.
I listed all characters in a column, and tracked down their placement from four different tier lists. (ignoring miis as only 1/2 the lists had them)
These are those lists.
1. Japanese List #1 from 2 Weeks after 3DS release[1] Weight: 2
2. Reddit Community List from 1 Month after 3DS release[2] Weight 2
3. Event Hubs Community list as on Dec. 10th[3] Weight: 3
4. Most Recent Japanese List[4] Weight: 4
The "weight" of each list means how many times that list was counted in the average. For example, Mario received scores of 21, 12, 19 and 23. With no adjustments, this would give us (21x2)+(12x2)+(19x3)+(23x4) / 11 = X where X is his weighted score. (11 is because 2+2+3+4 = 11). X in this case equaling 19.5
Some characters, like Link, recieved scores that were pretty different. When I encountered this, I adjusted the weight of a particular list based on the following "rule".
When most of a characters scores are within a 10 pt range, and they have an outlying score more than 10 in either direction of the highest/lowest, that score loses 1 weight. The exception to this was the most recent japanese list, which I never weighted less than 4 even if it was quite different from the others. Most characters needed no adjustment, about 1/3 needed one list changed, and Wario and Diddy each required 2 weight adjustments.
Link, for example got 37,25,11,40. I adjusted the outlying 11 by "1" leaving us with (37x2)+(25x2)+(11x2)+(40x4) / 10 (10 instead of 11, since the weight was reduced on list 3) which gives us 30.6
The number of * after each characters name means how many lists' weight were changed. No single list was weighted anything other than -1. So if there is "**" it means 2 lists were adjusted. This means that a * indicates a volatile placement.
(this was taken from my reddit post, sorry it's large, but I've been told before not to post things regarding tiers outside of this here thread)
