i had a thread just like this but no one ever saw it so im gonna post my idea here and maybe more people will see it. anyways there are three artifacts held in high security in hyrule. majoras mask the fierce deity mask and the four sword. Zelda is worried that these artifacts are in danger and sends link to protect them. link goes there to find ganondorf about to put on majoras mask. link puts on the fierce diety mask and ganondorf (now wearing majoras mask) and fierce deity link have an epic battle in which ganondorf is killed. upon ganondorfs death majoras mask leaps on to links face and link becomes corrupted and tries to capture zelda in a lust for power. she tricks him into drawing the four sword so that he is duplicated. zeldas plan has a few flaws though, upon the drawing of the four sword, vaati is released and so is dark link. link escapes with zelda and blue link purple link red link and dark link team up to defeat link and vaati. the six sages tell them to seek help from the other races of hyrule. they all split up to seek help. blue returns with a zora partner red returns with a goron partner vio (purple) returns with a guerdo partner and dark returns with a sheikah partner. they find that the sages are missing so they split up again to find them. after they find the sages they split up once more to find the three pieces of the key to links/vaatis castle. they face of against link and successfully defeat him. after that they decide to destroy both the fierce deity mask and majoras mask but ganondorf rises from the dead and puts the fierce deity mask on. then fierce deity ganondorf, majora, and vaati battle vio blue red and dark along with their partners and link and zelda. after the battle, vio blue red and their partners are left severly wounded. it is now up to link and zelda to defeat vaati, fierce deity ganondorf, and majora. after the most epic battle in zelda history, peace is restored to hyrule.
