Personality and History
While Sturgeon would much rather be curled up in bed in a quiet room with a book, Orca loves adventure and excitement. Orca is mostly known for his excellence in swordsmanship, and he teaches Link almost all the sword techniques, saying that he has to learn someday and it is right for a boy to know how to fight. Orca gives Link the Hero's Sword, which is the first sword Link gets in the game.
When they were young men, it was Orca and Sturgeon's dream to obtain ten Knight's Crests, allowing them to learn a powerful sword technique. After countless failed attempts, however, they both gave up. Orca realizes Link is a swordsman, so he sends him a letter asking him to collect the Knight's Crests, claiming it was the only true way to become a real swordsman. When Link brings them to Orca, he teaches him the Hurricane Spin. After this, Link is a better swordsman than Orca ever was, and Orca says that there is nothing else left for him to teach him.
However, this is not the end of Orca. Orca allows Link to play a minigame with him. In this game, Link must strike Orca with his sword as many times as he can without Orca hitting him. If Orca hits Link three times, the game is over. In the beginning of the game, Orca refers to Link as a mere page. If Link hits Orca 100 times, he bumps him up to the rank of "knight", and gives him a Purple Rupee. If Link hits Orca 300 times, he becomes a swordsman and gets an Orange Rupee, and then if he hits him 500 times he gains a Piece of Heart. If Link hits Orca 999 times, Orca will say that he has surpassed him, and give him a Silver Rupee. Also, if Link hits him 1000 times, Orca will say that he has lost track, since the game's counter only goes up to 999. After Link hits Orca 999 times, from that point on he will refer to him as "Master Link".
