we've pretty much seen all the potential that's there, most of it's humanly impossible for us to do
now most of the untapped potential is from yoshi to ness, i honostly feel that all 4 of those characters in that interval (yoshi, zelda, g&w, and ness) are much better than where they are on the tier list, g&w and ness are one of fox's and falco's hardest match-ups, zelda does pretty freaking good on peach, yoshi does great on all sword users, and there's more, but because of this potential that we have not seen yet, they stay at the bottom, i think they should get their own seperate tier because they are way better than anyone bowser and lower and not as good as anyone pika and higher yet
fox and falco have human limitations, we are not capable of controlling either character at top level, we do not have enough fingers and they cannot move fast enough in sync, we have used AR to see this potential but it's humanly impossible to do it
samus has untapped potential only because she's basically too good for her own good, she basically has everything you need, amazing recovery, very heavy, great set of projectiles, amazing grab reach, great air game, best CCC game, a pretty decent wavedash, fairly fast, can rack up damage fast, good KO power, hard to juggle, and is able to do 2 air moves in one SH, honostly, that's too much for us to handle, her only set backs are that she dies off the top at low percents and her ledge grab reach is crap, i think she has too much stuff for us to fully utilize, but it's really hard to think about 80 million things you can do at once, why i think she has untapped potential
ICs, there's two of them, but we've untapped a lot of it in the past year, since chu dat showed us all the possibilities and stuff, look, we're now wavedashing with alternating ice blocks, blizzards, or smashes, there's still a lot about them to learn but it's gonna be tough
ganon, he does have untapped potential, not much but it's there, have you noticed he has almost as little bad match-ups as fox and falco do, yes it's true, he's only bad against fox, falco, sheik, and falcon, fox is bad against falco and the marios while falco is bad against the marios, but look how low he is on the tier list, it's because he does so bad against those 4 characters but now we're starting to see stuff, we used to consider fox and falco counters, now they're not, sheik against ganon used to be the worst match-up in the game, now it's ganon on pichu, ganon's potential is coming out, falcon used to be another really bad match-up, now it's almost even, look how much things have changed
luigi, i don't see where he has any, we've pretty much figured him out
y. link, he has a lot, look, he jumped out of low tier into the new low tier, which is higher because the new low tier used to be the old mid tier, he has a lot of untapped potential, he keeps getting better and better, soon he might be able to surpass adult link because he does better on 4 of the five upper tiered characters, link does better against marth, there's a lot coming out of him
dk has a lot, it wasn't too long ago that we found out that he can 0-death fox and falco easier than anyone else in the game, only problem he still has is getting it started, but his stuff is coming out
mewtwo probably has the most potential in the game, look at his moveset, it's pretty dam good, amazing tilts, only sheik's compare, has argueably the best usmash in the game, fsmash is decent, dsmash is not so good, he has the best throw set in the game, amazing recovery, good up b, b is decent, forward has it's purposes, down b is just crap but completely situational, mewtwo's air game is amazing, what's putting him down is that he sucks, not his moves, his normal stats, he's not that fast, even with wavedashing, he's a big target, he's just as big as bowser, dk, and ganon, but he weighs just a little bit less than roy does, his sweetspot of most of his moves with the tail are in the middle (uair and utilt are the exceptions), but overall, he's got a pretty dam good arsenal of moves there, but he himself needs to be better, i play him once in a while, he acts like an upper tier character but he's not
falcon has his potential becoming tapped, him and ganon were at one point among the bottom 5 characters in the game, now look where they are, they're among the upper half, falcon used to be countered by fox, falco, sheik, peach, the marios, jiggs, and a lot of others, now he's only countered by what it looks like luigi and pika, and now only fox, falco, and sheik still have a slight advantage on him and he's consider the marios only counter and has a really good match-up against jiggs
other than that we've found most of the cahracter's potential
