Overrated:
5. Isaac (Golden Sun):
His series is dead for the time being. He's an Assist Trophy in Ultimate. His series even got new music without any additional gameplay content. Isaac missed his chance with the huge gap between the Melee-Brawl release, he missed it again with the huge Brawl-Smash 4 release window. It sucks for Golden Sun fans (which includes me), but that's the reality.
4. Waluigi (Mario spin-offs):
Sakurai has publicly said he views Waluigi as a "joke" request most of the time. Waluigi lacks a main series Mario, Wario Land or Wario Ware appearance of any kind. Worst of all for Waluigi fans, Waluigi is currently an Assist Trophy. Waluigi is almost definitely not going to be playable in Smash Ultimate. On the bright side, at least he gets those appearances and still appears in Mario spin-offs.
3. Shantae:
Small character, small series, small market, overshadowed by a dozen other platformer characters, most notably Crash Bandicoot, Ryu Hayabusa and Rayman. She doesn't have the mass appeal nor the notoriety to make people want her. I don't think she's even in the same league as Cuphead or Sans. 3rd party characters in Smash Bros have to be All-Stars, and unfortunately Shantae is not one.
2. KOS-MOS (Xenosaga):
I helped make the joke fake leak that mentioned KOS-MOS, and since then "KOS-MOS for Smash" has consistently exploded. I don't know why people think this would be the one character Bandai Namco would want in Smash. It makes zero sense, that series is dead in the water, and far from the most noteworthy JRPG series left to get a character. One positive is the "KOS-MOS for Smash" crowd has been mostly well behaved in my experience.
1. Geno (Super Mario RPG):
Geno is a secondary character in the 3rd most important Mario game released in 1996. Even among Mario RPG characters, Paper Mario overshadows Geno by a lot. A lot of Geno's base moveset the Mii Gunner already does. That is why Geno was a Mii Gunner outfit in Smash 4, and why he will probably return to that role later down the DLC line. Lastly I need to say it... these Geno leak mongers are all frauds.
Underrated:
5. Ryu Hayabusa (Ninja Gaiden):
While he's talked about, and while a number of people seem to be indifferent to him, it is weird how in a number of "characters I expect to see" list he is absent. Not a huge deal but it's a bit more than I expected. Also surprised how little discussion I see on him, given the unique balance of 2D vs. 3D era Ninja Gaiden you could see and the discussions and ideas that could spark.
Here is a good article on him recently from
Venus of the Desert Bloom
4. Sol Badguy (Guilty Gear):
Guilty Gear is probably the most underrated fighting game series of all-time, and its' impact is similarly so. Sol Badguy is maybe the coolest central character of any of the major fighting game companies, and he sticks out like a sore thumb. Guilty Gear mechanics for Sol in Smash could be glorious you could carry , as would the stellar Guilty Gear songs. But don't take my word for it,

on it.
3. Sora (Kingdom Hearts):
I believe deep in the Smash community's heart, the 3 characters that the most people wanted/the people who wanted them wanted them the most EVER are Sonic, Cloud AND Sora! In spite of that, we have an odd dichotomy clash between Disney corporate interests and the Sora Smash "magic" fan wishes. However IF Nintendo can get Disney to negotiate to get Sora in Smash (at a reasonable price), they almost definitely will.
2. Kazuma Kiryu (Yakuza):
While Yakuza is a bit of a darling among certain action game fans and story-driven game fans and somewhat of an outsider past that, there's a certain appeal to that kind of character to wider audiences, much like Terry Bogard. Between Kiryu's cool stoic personality, his many fighting stances, and the style of Yakuza, there's a lot of mass appeal there. The moveset potential is out of this world. It's an easy fit and would be a great and popular choice.
1. Chosen Undead (Dark Souls)/Souls-related character:
I have no idea why Dark Souls characters are so seldom brought up by anyone in Smash speculation. The series is popular. FromSoftware have invented and re-invented a new sub-genre for over a decade. Souls is admired among Japanese developers. The moveset writes itself. It could be a few different characters chosen. And a Souls character would be unlike any Smash playable character. It is hard to see us not getting Souls-related content in Ultimate.
