I think it's just years of conditioning that's made us associate "bottom tier" with "garbage". This is part of the reason I don't like tier lists that insist on having a large number of tiers, because that implies a degree of separation between each group that may or may not actually exist. (Honestly, what's the difference between A and A-? Or A- and B+?)
As far as I'm concerned we have Sheik in S, a large blob of characters that can reasonably function in a tournament in A, an even larger blob of characters that are by no means bad but just fall short of "you can totally win with me" in B, and then Zelda and co. at the bottom in C.

Not only that, but a character's past can haunt them as well. Who does that reminds you of? Zelda, Samus, Ganondorf, and Ike. It doesn't even have to be between games or from past games. It can happen because of recent opinions from top players or otherwise. Case in point: Leona Heidern in The King of Fighters XIII and quoting Juicebox FGC:
"Leona is, in my opinion, one of the most misunderstood characters in KoF XIII. At the very beginning, a handful of good players who are my personal friends, The Answer, Bala, and Romance, they made a preliminary tier list and they put Leona at the very bottom spot. Since then, she has this sort of bottom tier... this sort of bottom tier air that seems to have followed her around on the forums and other things. I don't necessarily think she is a top tier character, but I absolutely would say she is nowhere near the absolute bottom. She has to at least be mid-low for what Leona has and I'm going to show you what Leona has in this video."
Who does that remind you of? Falco, Marth, and Meta Knight. Along with Zelda, Samus, Ganondorf, etc., first impressions can and will kill characters. You can't get rid of past opinions that are plastered and archived or spread, believed, and internalized by others. Those are memes. No, not the stupid **** that people do like using kappa emoticons, saying "based", repeating phrases like "Roy's our boy", "that ain't Falco", "hoo hah", "beep-boop", and "ding dong", or talking about "dank may-mays". I'm referring to "
an idea, behavior, style, or usage that spreads from person to person within a culture". That is what meme truly means. Smash is a
culture and we as a culture have memes. With the internet, memes spread quickly such as the idea that if a character cannot D-throw to combo or even throw to combo, they're worthless or the increased usage of Diddy early on when people figured he was a bit too powerful which lead to cookie cutter Diddy players using setups they don't understand. Literally monkey see, monkey do.
Our meme is that bottom tier characters are worthless, hopeless, and easy to overcome. Our meme is that if a character loses something that defined them despite gaining new definitions whether found or not, they are marginally much worse. Our meme is that combos are much more important than reliable damage per hit. Our meme is that select characters are just bad and nothing can change that despite evidence against that idea. Our meme is that characters that are not clearly top or high tier are ultimately a waste of time. Our meme is that - I blame our younger and unorganized culture for this - defensive play or elements of defensive play such as zoning is camping, poor play, spam, and evidence of a lack of skill. Our meme is when something is not understood, it is either bad, poor game design, or "jank" - I hate this word. This is our culture. Don't like it? Deal with it. Or... try to change it.

The early KoF XIII tier list in question:
http://www.mmcafe.com/tiermaker/kof...ppj7fjm4pnl6ghy8cad6ke76jd32y9c2z7c4qb62y-bk6. I'm not sure if this is "ordered" other than the "tiers", but notice how Leona's completely isolated. This was an early tier list and from top players. Not just 1 player like if only ESAM isolated 1 character, but 3 top players. That's like if Zero, Nairo, and Mr. R agreed that Lucina should be isolated below everyone.
