Princess Hilda

Princess Hilda is a character in The Legend of Zelda: A Link Between Worlds, and is revealed to be the game's main antagonist towards the end of the game. However, she is betrayed by her advisor, Yuga, during the final battle.

History
When Link chases Yuga through a portal in Zelda's room, he ends up in a new world. He witnesses Yuga fusing with Ganon to become YuGanon. Just as YuGanon is about to kill him, Hilda teleports nto the room, and seals him with dark magic. She takes Link out of the castle, and speaks to him in a dream. She claims Yuga's actions are her fault, and that the Seven Sages are trapped in paintings scattered around Lorule.

She tends to speak to Link telepathically whenever he enters a new area in Lorule. She hints if a sage is there or not. Occasionally, when Link rescues a sage, Hilda will be shown talking to Zelda's painting about how lucky Hyrule is.

When Link recieves the Triforce of Courage from the Seven Sages, he heads to Lorule Castle. Hilda breaks the seal she placed on the castle so that Link can get in. When Link gets to the top of the castle, he is confused that Hilda is the only person in the room. She taps Zelda's painting, and the Triforce of Wisdom comes out. She then faces Link, and explains to him that long ago, Lorule had a Triforce that was destroyed by her ancestors to stop a war that was going on. She then explains how much she envyed Hyrule's Triforce, and then reveals she plans on taking Hyrule's Triforce, now that she has all three of it's owners in the room. She summons YuGanon to attack Link.

Link defeats YuGanon, and worried about Yuga being harmed, she tells him to give her his Triforce of Power. YuGanon starts chortling, then reveals he was double-crossing Hilda the entire time, and plans to use the Triforce to remake Lorule in his image. He traps Hilda in a painting, then seals her painting with his body, and becomes Dark YuGanon. He tries to attack Link, but luck stays with Link, and he defeats YuGanon. Hilda can be seen unconcious in the spot where Link killed YuGanon. After Link frees Zelda from her painting, Hilda gets up, and tries one last time to attack, but is stopped, suprisingly, by Ravio, a shopkeeper Link allowed to live in his house. Ravio reveals that he is the Lorule version of Link, then talks sense into Hilda. Hilda realizes her mistake, and takes Link and Zelda to Lorule's sacred realm. She uses the bracelet Ravio gave to Link to send the two back to Hyrule.

In Hyrule, Link and Zelda are in the Sacred Realm, with the Triforce in front of them. They wish for Lorule to get its own Triforce, and the last scene shows Hilda weeping in joy when the Triforce of Lorule is restored.
