We know that  Princess Hilda of A Link Between Worlds is the land of Lorule’s version of Princess Zelda, but her character is still a mystery. At this past weekend’s New York Comic-Con, Eiji Aonuma gives a little insight on Princess Hilda:

“Obviously they’re both princesses and they both have kingdoms that they love and want to support, but Lorule is a place where something cataclysmic has happened in the past. So, with Hilda, her feelings of wanting to save her country are perhaps a bit stronger than Zelda because Zelda is living in peaceful Hyrule. It’s not as strong for her. I think that difference in motivation for each of them is where the differences come in.”
