Alright so now we're on the Knights of Hyrule!
The Knights of Hyrule are some of the baddest Knights around and no folks, I'm not talking about the guys you see guarding doors, patrolling the castle grounds, etc in OoT, MM and TP. Those guys are just guards/soldiers, the Knights however....are on a completely different level.
So without further ado, let's begin!
The Knights of Hyrule are a clan that protect the Royal Family, their members descended from the Hero who governed the crest of Courage. Legend has it that the Hero one day will reappear within their ranks
-Taken from Hyrule Historia
They protect the Royal Family and are descended from Link.
The King of Hyrule ordered the Seven Sages to seal the Sacred Realm, the Knights of Hyrule guarded the sages as they offered their prayers, but demons descended upon them from within the Sacred Realm and a fierce battle unfolded in which a majority of the combatants were killed.
- Taken from Hyrule Historia
The Knights protected the Seven Sages from demons, long enough for them to close the Sacred Realm.
Just a visual representation of the above quote.
Here Link's dad slices a monster in two.
Here he breaks free of Vaati's control, throwing a dagger aimed right at his head(he was disguised as Zelda at the time.)
Here the Hyrule Knights save the 4 Links as they were being squeezed by Vaati's tentacle appendages, they then fight together with the Links and drive Vaati away(although Vaati was pretty immortal at the time and he was luring the 4 Links into a trap, but still.)
Here Knight Valenzuela is able to make stone shattering blows with his blade.(He was intangible at the time but could still attack, being transformed by Ganon into attacking Link)
Here Knight Raven(who is a direct descendant of Link) cuts through a spear and knocks Link out, quickly catching up to him as he ran.
Here Raven takes on multiple enemies even after being stabbed in the shoulder by an arrow.
Here he is fighting with Link and defeating Veran.
