The Hero of Time or the Hero of Hyrule, I don't know which. The Hero of Time loses seven years of his life and it is his own fault that Ganondorf becomes king and Hyrule. When he saves the world at last, he cannot find the fairy companion that helped him save the world. He is separated from his Zelda in the repetitious and horrifying world of Termina, and afterwards he obviously dies in sad circumstances. His soul remains to train the Hero Chosen by the Gods to ease his own life's regrets.
The Hero of Hyrule grows up in the far from utopian aftermath of the Hero of Time's death, but he saves the world and the princess. Gaining the entire Triforce, he saves the alternate worlds of Holodrom and Labrynna, but becomes lost at sea and is forced to destroy an entire dream world in order to escape. This task is surely a huge emotional blow for Link, and coping with the destruction he has caused is not his only problem, as he finds himself lost at sea on a small piece of raft, in the middle of the ocean.
