You can make nitpicks like this for nearly any new Nintendo character at this point though.
Comparing Raven Beak to protagonists and major recurring characters aren't "nitpicks", they're why he doesn't fit your examples.
Like, at some point a new character inherently just will not be as requested or have as much history with their franchise as older ones obviously. As more characters get added, smaller franchises will get more characters than what is needed to "represent them" properly or whatever.
I agree with this - but it's not going to go Mario -> Metroid. Just as Smash takes from the biggest (feasible, active) Nintendo IPs available and roughly works its way down (barring unique spots Raven Beak wouldn't fit), the obvious next series to take from its b/c-tier cast would be Zelda. Not Metroid.
And the Zelda b-tier characters encapsulate all your points for Raven Beak, but better. They're generally more popular, Zelda is bigger and the characters are more well-known, some of the b-tier actually recurs (basically all of it, if you count spin-offs), Dread did well for Metroid but Zelda just had two games which performed seven and
eleven times better. Also, Metroid just got two new characters, Zelda hasn't had one since Brawl.
Yea metroid is not a big series, but it feels stupid to be dismissive of adding a new character from a Nintendo series that just just had its biggest game ever.
First, Dread can be represented without a newcomer. Second, Dread will have its protagonist playable. Third, this could be said of many series because of the Switch effect. Again, it would apply better to Zelda, Kirby, Splatoon and AC, all of whom have a more generally popular character and are considered below how represented they could be. It even applies better to Pikmin.
Lets also not act like ZSS and Dark Samus are amazing Metroid reps that actually represent anything meaningful from the games. Both could easily get the axe in the next game.
Good luck with Sakurai, the guy who's opinion actually counts, agreeing that any character is effectively a bad choice.
Also idk what you're on about with this not meaningful representation: Dark Samus
is Metroid Prime, the namesake of and the main recurring antagonist to the entire sub-series.
Rather than comparing him to other characters already in Smash, compare him with other characters people are asking to be added. Among Nintendo characters it's not like he is THAT unlikely. Like, the obvious favorites are long time requests that haven't made it in yet. Bandana Dee, Dixie Kong, Waluigi (ew), Toad maybe.
After that he's in the mix with the other newer characters/requests like a new pokemon, Totk/Botw character, Octolings/Splatoon character, Tom Nook, Noah/Mio ect.
Ok.
He's far less requested than Waluigi, BWD and Isaac.
He's a one-off villain unlike protagonists like RFT or Akira Howard.
He's not a recurring major character like Dixie, Toad, Octoling, BWD or Tom Nook. All of whom come from bigger series.
He's a one-off from a moderately successful series like Metroid instead of a one-off from a blockbuster, AAA series like Zelda.
He's not from a series that gets promotional inclusions like Pokemon, FE or Xenoblade.
His (mid-size) series just doubled in count, which makes it unlikely they would be priority for another character. Unlike Zelda or Kirby.
Metroid having four characters is completely in line with its size/success. It's in no way underrepresented. Again, decreasing chances of priority.
Any positive he has, another option eclipses him.
Yea you can argue all the characters I listed have better cases than him, but I wouldn't say a lot of them are THAT much better.
I would. Your argument is literally that the level of character inclusion changes, it bypasses all the stronger cases, and among all the possible characters that could favor, it will be Raven Beak. So that entails the methodology deviating, selective omission
and extreme luck.
None of those other characters need anything to change. They still need luck, but they can get in based on existing parameters.
