Knight

Unique Moves
The Knight had several unique moves:

(Low Profile, Back)

The Knight removes his sword from his belt and chops downward into the shoulder of his target roughly, slashing them as he quickly pulls his sword out. Providing his victim with a large fatal wound, he lets them fall to the floor, dead.

(Low Profile, Front)

The Knight unsheathes his greatsword, before knocking his target's legs from underneath them with the side of his sword. As they make contact with the ground, he hacks his weapon into his victim's back, severing their spine, before pulling his sword out and storing it away.

(High Profile, Back)

The Knight chops with his sword into the side of his target's waist, getting his greatsword lodged in their flesh. Forcefully, he slashes through their body with a mighty swing, dislodging his sword and spinning his victim in the progress. Afterwards, while his target's dead body is left on the ground, the Knight stores his greatsword back at his belt.

(High Profile, Front)

The Knight clotheslines his target in the neck with his arm, making them topple onto their back. He then stabs his sword into his victim's heart and lets it go, before grabbing it with his other hand and pulling it out, taking the time to sheath his blade while his target bleeds profusely, their heart pierced.

(ACB Bench Kill)

The Knight stabs his target in the chest, before lifting them off the bench and to the side. His victim feebly grasps at the blade, but eventually goes limp. The Knight then pulls back the sword quickly, withdrawing the blade and making his target fall off of the tip.

(ACR Bench Kill)

The Knight grabs his seated target's foot and drags them off the bench, until their head rests against it. Before his victim can do anything to defend themselves, the Knight forcefully kicks them in the face, violently sending their head backwards and breaking his target's neck on the bench behind them.

(ACB Aerial Kill)

The Knight jumps from above a rooftop onto his unfortunate target, crashing into them with gravity aiding his heavy armor, before removing his greatsword from his waist and forcibly slashing downwards into the middle of his victim's head. Ripping his weapon out his target, the Knight replaces it at his waist.

(ACR Aerial Kill)

The Knight leaps down from a rooftop and unsheathes his sword in mid-air. As he lands on his hapless target, knocking them to the ground, he roughly impales their heart with the tip of his greatsword before leaving them to die from blood loss.

Trivia

 * Upon closer inspection, the visor of the Knight's basic helmet, paired with the engraving on his helm, forms the Templar cross.
 * The Knight bears a close resemblance to a Brute, albeit with flashier colors, lighter armor and a different helmet.
 * However, the Brutes from Assassin's Creed II have similar helmet designs.
 * The Knight also resembles the Captain Guards featured in Assassin's Creed II: Discovery.
