King Knight isn’t a king, he is a king-themed knight. But that doesn’t stop him from making decrees! As the lord defender of Pridemoor Keep, he commands a formidable army of minions. Experienced with repelling invaders who dare try topple his malevolent monarchy, King Knight is a master of single combat. And because he’s dressed to the nines at almost all times, he’s always ready for a brutal coronation!
As one of the first members of The Order the player can face, King Knight is a fairly simple boss. He moves slowly and in a flashy prideful manner befitting of his personality. His main method of attack is to hop around the stage before executing a paralyzing stomp (if the player is on the ground, they will be stunned for a short time). Should the player fall prey to his attack, King Knight will slowly walk over to them and then strike with his scepter.
King Knight also uses a slashing charge which makes him quickly move in a straight line through the screen. After depleting approximately half his health, he will move into a corner and two horns will launch confetti into the air. While this is a good time to deal damage to him, the confetti will inflict damage to the player as it falls slowly to the ground.
King Knight's stomp will change the floor levels so that the ground is no longer flat. The horns will also launch cards which can be Dash Slashed. He may also move in the air with help of Propeller Rats, leaving him briefly vulnerable, but also moving away from Specter Knight's reach.
After the player defeats The Order of No Quarter again in the Tower of Fate and rescues them, if the player has Ornate Plate equipped, King Knight will mention how Shovel Knight has "picked up" his style if spoken to.
Like the other Dig the Vote winners he has a steam emoticon.
King Knight's crown is not made of real gold, as discovered by Plague Knight after defeating him in Plague of Shadows. This is likely a reference to the story of Archimedes, a scientist who was tasked with determining whether or not the King's crown was made entirely of gold, or if the King had been tricked. Archimedes determines at the end of the story that the crown was mostly not made from gold.
An old teaser of King Knight's game-play showed that some of his mobility relies on jumping on top of enemies, and bouncing across them. Yacht Club Games also stated that his movement would also involve a Propeller Rat, which plays a role in his Boss Fight in Specter of Torment.
It is implied in King Knight's dialogue in Specter of Torment that he was already serving the Enchantress before the game, but slacking off on the job. Specter Knight was sent to straighten him up in his duties, and during the ending, King Knight finally takes over Pridemoor Keep.
