The titular Blue Burrower himself. Shovel Knight rushes Shovel Blade first into danger to defeat the Enchantress and save his lost love.
10-Minute Retirement: While not precisely stated how long he was out of action, he's still sharp enough for most of his enemies to either respect or fear him.
Badass: Fights his way through eight bosses by himself only getting help from Shield Knight during the last fight. Even more impressive in the New Game Plus mode. Both he and the player have to be this to make it through to the end.
His main weapon is a Shovel Blade, which is exactly the weird combination weapon that it sounds like. This is Lampshaded by several knight NPC's in the village, who laugh at the idea of using a shovel as a weapon.
Shovel Knight also finds such items as the War Horn and even a Fishing Rod (which has an anchor for a hook) during his adventures.
Shovel Knight's beloved. Years ago, she journeyed alongside Shovel Knight on many adventuring campaigns, and the two were inseparable and unstoppable partners. However, during a journey to the Tower of Fate, a cursed amulet unleashed its magic, and Shield Knight disappeared. Shovel Knight now searches the land for any clue as to her fate and whereabouts.
Badass in Distress: Emphasis on the badass. She's fully capable of assisting Shovel Knight right after being free of a curse that who knows how long it lasted. On top of that she holds an attack that downs him instantly long enough for Black Knight carry Shovel Knight to safety.
Expy: Of Proto Man. Both utilize shields, wear red-colored armor, and have a major relation to the retrospective protagonist.
Fashionable Asymmetry: She uses a pair of Asymmetrical Shields; one fist-sized, and one almost as tall as she is.
Faux Action Girl: Subverted. At first she looks like an allegedly competent knight who still managed to get herself kidnapped to fulfill the classic "rescue your girlfriend" Excuse Plot, but it's revealed that she simply got punked by a surprise curse in an amulet among their loot, turning her into the Enchantress, which could have just as easily happened to Shovel Knight if he had been the one to touch it. And during the final boss battle, it's shown she's every bit as badass as Shovel Knight is.
The Heart: Her apparent demise in the Tower of Fate caused Shovel Knight and Black Knight to part ways.
Luckily My Shield Will Protect Me: The larger of her Asymmetrical Shield is nearly as tall as she is, and can turn aside all manner of attacks. It's even enough to stop the Enchantress's final attack, albeit at the apparent cost of the shield itself.
One Head Taller: The top of Shovel Knight's head (not his helmet's horns) is level with Shield Knight's shoulders.
Shield Bash: Her fighting style. Generally, she uses her shields to stop attacks until she can get close enough to pulverize the enemy with her shields.
Turns Red: BOTH of her forms do this- the first flies underneath the arena and attacks you from there, and then moves around more when she eventually gets back up, and the second gets even more attacks.
Red Baron: "The Rival". Later on, this is replaced with "The Defender", as his true motives come to light.
The Rival: At least tries to prove himself as this, persistently challenging and confronting Shovel Knight, no matter how many times he has been defeated. The title of his boss theme also outright refers to him as this.
Spikes of Villainy: His helmet and shovel are notably more pointy than Shovel Knight's. Subverted by the fact he's not evil at all.
Recurring Boss: He's fought a total of three times throughout the game—first at the end of the intro stage, again in a map encounter about halfway through the game, and once more at the end of the first Tower of Fate stage.
Tennis Boss: While it's not a required method of engaging him, hitting his purple fire attack will reflect it towards him. He will hit it back repeatedly during any encounter other than the initial boss battle.
Bling of War: Solid gold armor, with a "royal" cloak and a crown built into his helmet. If you equip the Ornate Armor during the Boss Rush, he'll compliment you on your taste of armor afterwards if you save the Order.
Break the Haughty: After the rightful king is restored, he forces King Knight to scrub the floors of Pridemoor Keep.
Dishing Out Dirt: He frequently burrows into the walls and floor of his boss room, and can attack by sending walls of dirt hurtling at Shovel Knight or even dropping dirt blocks all around him.
Doppleganger Spin: 4 piles of dirt emerge from the floor, one of them contain Mole Knight digging from the floor. Each pile Shovel Knight doesn't dig bursts forth and spews lava, although everything is defused if he digs up Mole Knight.
Sequential Boss: At first, all he does is run around throwing wrenches in the air, but after he's defeated in this phase, he jumps into his Tinker Tank.
Shout-Out: To Metal Man. In addition to the conveyor belts in both characters' stages, he also has a massive weakness to a gear-shaped weapon.
The Klutz: Trips over his own feet constantly in his boss fight.
Turns Red: He will desperately fling wrenches all over the place when damaged enough. During the second phase of the fight, he will turn the slow moving missiles of his mecha into bouncing bombs, making the way to the top of his mecha more dangerous.
A huge viking helmeted knight. Apparently he and Shovel Knight have fought before. He wields a massive snow shovel and is found in the remote Stranded Ship.
Badass Beard: Appropriate for being a Viking knight, he has quite the Nordic beard.
Informed Flaw: He's said to have the most annoying laugh in the Order, but is one of the few not to laugh before his boss fight.
The Big Guy: Largest member of the Order, and is only rivaled by Baz for largest character in the game.
The Rival: While Black Knight is a mirror of Shovel Knight, Polar Knight is his opposite, being a ruthless Viking knight wielding a snow shovel. Pre-fight dialogue implies they've fought before, and Polar Knight seems to genuinely wish that Shovel Knight would join up with them.
The Stoic: Doesn't emote beyond the occasional "Hmph!"
Turns Red: Will start digging up one hit kill spikes from the ground of his arena.
Bonus Boss: None of them are mandatory to beat the game, but offer a nice challenge.
Hero of Another Story: The composer's notes for their theme, "Fighting With All Our Might", implies they are this.

Turns Red: Reize will create several fireballs that will orbit around him giving extra protection.
Mr. Hat is obsessed with hats, but for good reason! For although he wears a helmet, each hat that he places atop his head gives him the powers of that hat's owner! Mr. Hat can switch from a charismatic foppish dandy to military genius in a moment, and he takes great pride in his varied fighting styles. Lately, though, there have been rumblings of an even greater warrior who wields a Shovel Blade; one with a wonderfully blue, horned helmet...
Cash Gate: You have to spend 3000 gems to make everyone leave his shop before he'll challenge you; however he drops over 5000 when you beat him. If you chase him around town after beating him, you can get all the gems you spent back as well.
Insistent Terminology: Shovel Knight is confused as to why Mr. Hat wants his helmet, since it is, well, a helmet. But Mr. Hat insists that as a piece of headgear it still counts.
Nice Hat: With the additional bonus of gaining a special power for whatever hat he wears.
The storm is coming... With a fearsome rope whip and the toughest-looking armor around, one might think that the traveling warrior Baz would be a shoe-in to join up with the Order of No Quarter. Imagine his surprise when he was rejected! He now roams the land, taking out his anger on passersby. Could he ever prove himself strong enough to earn the title of "Baz Knight"?

Creator Cameo: He's quite obviously Jake Kaufman in a suit of armor.
Expy: He appears to be one of Manbo from The Legend of Zelda: Link's Awakening. A fish who does a lengthy dance sequence before he helps you out. He grants you potions just like Crazy Tracy from the same game.
