On the subject of Zelda rep, I personally think it's pretty stupid to write them all off as "One-Off so unimportant", when the Smash cast is already full of one off ! With more than one in the Zelda section too haha
Zelda don't have a Main cast that stay the same, only Ganondorf is recuring out of the character we already have in, and ironically, he was at his first apparition only by the time of Smash Bros Melee, Links and Zeldas all change through time, and the best they can do is appear 2 times in a row, never a 3rd time, they do have recuring "roles" though
Companions (Midna, Spirit Zelda, King of Red Lions, Fi etc ...)
Vilains (Skull Kid, Ghirahim, Vaati, Ganon)
Side Helpers (Impa)
And more !
You can represent that instead of "recuring" characters that obviously doesn't exist in a series like Zelda (Well some does like Vaati or Tetra, didn't make them more likely though), to in the end, have a good representation of what the series as a whole is, with it's rotating cast represented by the most popular of them !
And finally, for those saying that "Zelda fans are super divisive ! That's why they didn't get a rep !", that's just plain out wrong, we didn't get a rep because we're divisive, we're divisive because we didn't get a rep, I can assure you, that if Mario didn't get a new rep since Melee, some people would want Rosalina, others would want Waluigi, others would want Bowser Jr, and others Toad, and even today as they get a new rep every game, they pratically have the same numbers of "Front runners" in popularity than Zelda
So yeah, not our fault that the series keep on making amazing characters every single game, and that Smash is using none of them haha, plus, in term of personal experience with Zelda fans, we're not one to make war to another character of the same franchise, Skull Kids fans are shill toward Midna fans and vice versa, of course there is always bad apples out there, but mostly, Zelda fans are hella chill toward any choices of their franchise, even if they have different favorites, and that's fine
Compared to other series, and taking my exemple from before ... I see Waluigi fans making war toward Geno fans, or Toad fans making war toward Waluigi fans wayyyyy more often than I see Skull Kid Vs Midna Vs Impa happen really
At least that's my two cents in all of this
