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. His main method of attack is to hop around the stage before executing either a paralyzing stomp (if you are on the ground, you will be frozen for a short time) or 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 do damage as it falls to the ground.
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.
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.
