It’s Zelda herself. Nintendo made it a point to hint that the character in the trailer wasn’t Link, and for every reveal of Zelda featuring Link as the protagonist, it always features him wielding The Master Sword and Hylian Shield. It’s only fitting that for a game featuring Zelda herself, they’d feature her signature weapons: a bow and magical arrows. It’s her weapon of choice in every single game where she has to fight. She uses them in Smash, she uses them in the upcoming Hyrule Warriors, she uses them in Wind Waker in the final battle against Ganon, etc.
I feel lame saying this but idk if I’d want to play as Zelda. I mean she always ends up getting captured and imprisoned in every game. What would the game be? Sitting in a jail cell, crystal or painting idly passing your time until Link, he come to town, he come to save the princess Zelda?
Jokes aside I guess I just relate more to Link as a protagonist. The lost boy who figures out his true purpose and power on an epic adventure is a fun story concept and I’ve enjoyed it thus far. I guess I’ll wait to see what the future holds.
