Gohma
The first boss is Gohma, a spiderlike creature who lurks in the dungeon of the Great Deku Tree. Gohma will jump on the ceiling, scurry around and glare at Link. Link must throw a Deku Nut at her eye, which will cause her to fall. He then needs to slash at her eye with his sword while she is immobile. If given enough time on the ceiling after being hit, Gohma will lay eggs which then hatch into baby Gohmas. It is possible to slash the eggs before they hatch. Repeat until Gohma dies.
Dodongo
In the death mountain dungeon a large lumbering reptile named Dodongo holds sway. Dodongo waddles around a lava pit, and will periodically open his mouth to breathe fire. Link should throw a bomb into the creature's mouth when it opens, hit it with a sword while it is lying paralyzed and then stand right on the edge, but not in, of the lava pit while the angry creature rolls around. Repeat until dead.
Barinade
Inside of the whale is an electric anenome called Barinade. Link needs to throw his boomerang at it to lower its defense. In response, Barinade spins, extending little jellyfishes called Bari toward Link. Link has to destroy the Bari. When the globule mass once protected by Bari is exposed, Link should paralyze it with a boomerang and slice it with his sword until it dies.
Phantom Ganon
Phantom Ganon can be found in the forest temple. He appears on horseback, and rides through paintings on the wall. Link must watch the two painting the baddie comes out of, and when a purple spiral appears around the real one, Link must shoot an arrow at him. After a few hits, Phantom Ganon will dismount from his horse, and shoot energy at Link. Link should swing this sword at the energy and fling them back at the bad guy. Link should alayas hit the attacks back at Ganon, who will eventually get hit with his own attack. Then Link must rush forward and thwack at the Ganon with his sword. Repeat until the phantom is finished.
Volvagia
Volvagia, a giant dragon, lives in the Fire Temple. He'll come out of his hole and fly around a good bit. Eventually he'll go into a hole and then just pop his head out. Link must run forward and hit Volvagia with the megaton hammer. The dragon'll get ticked and fly out again. At some point in time, he'll knock rocks down at Link. Link should hang onto the side of the ledge so as not to get hit by the painful projectiles. Continue to whack Volvagia until he dies.
Morpha
Morpha resides in the Water Temple. Link must use the longshot to get the nucleus out of the tentacles, then slash at, hack or hit it with the hammer. After being hit a few times, Morpha will develop a second tentacle. Avoid both. If taken by one, Link will be thrown against the spikes on the walls.
Bongo Bongo
Bongo Bongo lives in the Shadow Temple. Link must wear the lens of truth almost all the time in order to see the enemy's eye. Link must shoot an arrow into each of the baddie's hands, then use the Lens to see its eye and hit that with an additional arrow. Then, Link must run forward and slash the eye while Bongo Bongo lies prone. Eventually, BB will die.
Twinrova
Twinrova abides in the Spirit Temple. Twinrova first appears as two witches, one of fire, one of ice. To defeat them, use the Mirror Shield to reflect an attack of the an opposing nature at a witch. (i.e. if the fire is shot at you, direct it at ice) After a few hits each, the witches will combine. Now, Link must store three spells of the same nature (all ice or all fire) on his shield and use these to knock her to the ground. Then Link must rush in with his sword and slice her. Soon she will die and Link will be ready to fight the big cheese.
Ganondorf
Link should hide in a corner when fighting him, because Ganondorf knocks the floor out. He will throw energy balls at Link, who must reflect them with his master sword until Ganondorf at last gets hit by his own magic. Link should then use a Light Arrow to hit Ganondorf and knock him down. Link must then longshot onto Ganondorf's cape and hack at 'dorf until he grunts and rises. Then, Link should head back into the corner and repeat this process. One of Ganondorf's attacks is to make a large dark ball throw it at you. It will split into 4 small balls that will hurt you. Do not try to use a Mirror Shield, but rather, do a magic twirling blade/sword attack thingy to send them all back at the baddie.Ganon
It is recommended that you use Biggaron's Sword or the Megaton Hammer, preferably the former. Ganon will follow you weilding large swords. Link must run towards him and roll between his legs. Then you should turn around, target his tail and kill it. Do this until you can access the Master Sword. When you get the Master Sword, repeat the above process until he dies.
