Zelda is my favorite series. So honestly, whoever they add as the 5th rep, will became one of my mains. As long as it's not Tingle or Groose. They are the only Zelda characters I can say I hate. There's so many great Zelda characters, I'll just be happy if it's not one of them.
And if Sakurai is attempting to add villains and females, don't you think the Zelda series sounds like a great place to pull from? Think about all of the popular/supporting characters. Link, females, and villains. Tingle and Groose the two male protagonists in the series that get recognized by fans, which are, coincidentally, my least favorite videogame characters. Adding them would make it look like Sakurai is trying to avoid adding females and villains.
Cool Zelda characters (many with 0& chance): Marin, Malon, Romani, Cremia, Nabooru, Impa, Saria, Ruto, Agahnim, Tetra, Ashei, Agitha, Aryll, Twinrova, Vaati, Veran, Onox, Zant, Midna, Ilia, Fi, Ghirahim, Demise, Majora, Skull Kid, Yuga, Hilda......
No replies like "YOU LIKE _____ AND NOT TINGLE/GROOSE?" please. The answer will be yes.
