Part 1, Ganons Puppet Zelda: This is basicly the same as fighting Ganondorf on Ocaraina of time. When Ganon shoot a ball of light use your sword to shoot back (Dont forget to dodge his Triforce and Chargeing attacks). Reapeat this 3 times and move on.

Part 2, Beast Ganon: Ganon will transform into a beast and this part is best done in beast form too so I recomend it. When Ganon charges at you, press A and Minda will grab his head so move the control stick and throw him over then when hes on his side jump on him and take large chunks out. Reapeat 6 times and move on.

Part 3, Dark Lord Ganondorf (Horseback): This Part is easy follow Ganondorf around Hyrule Field and lock him on and Zelda will shoot light arrows at him. While hes stunned slice him. Reapeat a few times and move on.

Part 4, Dark Lord Ganondorf: This will be a long battle so when ever theres a chance to do a sword clash press A and reapeatadly press A and then some heavy damage. Do some Back Slices and Helm Splitters to hurt him aswell and you can distract him with your fishing rod. When hes on his back to a Finish and get that Triforce sign off him for good! Dont forget to watch the credits theres some bonus sceanes during it!
