Zelda's back! Just like a lot of us suspected, she's just been confirmed, coinciding with the Japanese release of Link Between Worlds.
Something very interesting about her confirmation is that almost none of the pictures actually show her attacking, and the only picture that seems to show an attack is something new:
She could have an entirely new moveset. She could be another 'puppet' character like Rosalina. Or this could just be an assist trophy and she has the same moves as in Brawl, who knows!
At the very least, we're either seeing a brand-new attack or a brand-new assist trophy here. Either one is welcome!
