Dragonslayer Armour is one of the main bosses in Dark Souls 3 and is the armor which a knight once wore in the Age of Fire that's now hollow on the inside. He guards the entrance to the Grand Archives, and defeating him is mandatory in order to complete the main story. It is supposedly controlled by the Pilgrim Butterfly, the creatures in the background of the fight.
