There was clearly a lot of hope involved.
The ones that truly stand out:
Olimar... Brood is a good case for Olimar's rise by himself
Kirby? His air game is very good, capable of WOPs at times, and most of the abilities he gains from higher tier characters give him some of their best attacks, such as Mach Tornado, Grenades, Lasers, Shield Breaker, etc.
Wario? While his aerial game is second only to Meta's [counting off stage antics], but his lack of a projectile and/or ground speed kind of hurts him in my eyes, like I said a few posts back I probably put him lower than I intended to, but I still think he's below at least ZSS
Mario?!?!?!? Like I've said in the past, Mario is extremely underrated, call it bias if you want, that's just how I feel, he has a momentum "stall", a jab lock, a method to move rapidly horizontally in mid-air, a small chain grab game on heavier characters, a recovery that can stage spike, a special that can stop Fox/Falco/Wolf's recovery (and a small bit of super armor), another special that can gimp like crazy, good aerials, a good projectile game (that can also counter planking due to the angle it falls at), a good ledge game, etc.
Lucario? To be honest I'm not sure why he's that high to begin with (other than his side b, roll, and down aerial), most of his attacks are average and his recovery is not exactly amazing . . .
Pit? I only moved him down one spot, was it that big of a deal that you can't see it happening?
Yoshi?!?! Mid-air jump is not gimpable unless the user air dodges or attacks while doing it. He also has a reliable chain grab/grab game, Yoshi's grab outprioritizes Mach Tornado and several other recovery moves, and his Up special is very underrated, while it doesn't gain that much vertical height, it can be used as many times as you want and retains the momentum he had before the attack (with a slight upward boost), allowing the character to stall in the air for a bit or move quickly to the left or right through it.
Toon Link? I have a similar stance with Lucario as I do with Toon Link, though in TL's case the only thing I find to be noticably good are his down aerial and ground speed, otherwise he feels a little too average to be as high as he is now.
Wolf? I only moved him two spots from where is at currently . . . . 20th isn't really that unreasonable, he was there on the 2nd version of the list.
Peach?!?!?! While not really a stat that proves it, she was around there in the 1st list, she's well rounded, but there's just something about her that feels like she's ALMOST reached near her maximum potential, similar to how Meta is pretty close to that, with Diddy catching up on him due to the oil well of potential that the peels give him.
Ness?! This is actually higher than he was on last year's tier list, the jump he made in between then and v4 was way too high. imo
Lucas? Only one spot higher than what he is currently . . . . pretty much everything about him, except his throws, are better than Ness, most notably his recovery (especially when you consider the Zap Jump tech, which gives him the 2nd best, if not the best mid-air jump of all the characters when done correctly.)
Captain Falcon?!?!? Good aerial game, two recoveries that can either spike or stage spike, a grab game with chain grabs, well rounded smashes, good speed, and a moderately reliable low-mid percent finisher, he's not really as terrible as most people make him out to be, even though he's still ridiculously nerfed compared to his two former appearances.
Ike?!?!? See my response to the other post
