The final boss has Shield Knight fight alongside Shovel Knight once more.
The dialogue before the fight:
Shield Knight: When the amulet shattered, the magic within it was released! It's already gathering. It will escape and wreak havoc on everything... Shovel Knight: Unless we stop it. Shield Knight: Unless we stop it! We can destroy it for good, here and now! Shovel Knight: But we're both weak from battle! Shield Knight: I've never been more ready. Come on, Shovel Knight, let's fight together, like old times. Now... stay close to me!
Not to mention you finally see why Shield Knight was Shovel Knight's partner. As you bounce off her shield to reach the Enchantress, you see how much their fight styles compliment one another.
The duels with Black Knight are all awesome, but Yacht Club Games saved the best one for last. Black Knight, now revealed to be good, is forced by The Enchantress to fight via mind control. Eventually, Black Knight begins to sprout wings and rain meteors down on Shovel Knight. It's an exhilarating, amazingly epic conclusion to the rival fights.
Every boss fight is pretty awesome, but special mention goes to Tinker Knight's fight. It starts off very simple and embarrassingly easy. Then, after you completely deplete his health, the floor collapses and tiny little Tinker Knight leaps into a Humongous Mecha!
Shield Knight surviving her You Shall Not Pass! moment in the end. Also, she didn't need Shovel Knight to catch her. It's appreciated, but she can take a fall. She's not the Damsel in Distress, they're partners.
Fighting Shovel Knight as a boss in Plague of Shadows. He uses his relics against you (Flare Wand, Throwing Anchor, War Horn, Phase Locket, Chaos Spheres) and even recovers his health with an Ichor of Renewal. The fight is every bit as awesome and frenetic as you'd expect.
Plague Knight's final boss starts off fairly simply, but brilliantly with a shadow clone Mirror Match against the Plague of Shadows, which is a copy of the original Plague Knight boss fight. If you thought it was frantic the first time.... Followed by the second phase: The Corrupted Essence, a giant, demonic bird version of Plague Knight, riding on some sort of alchemical machine that guards its weak point.
An alternate way to beat the Plague of Shadows is to have Plague Knight stand still for about 30 to 40 seconds. Do this, and you get a hidden line of dialogue before moving to the second phase:
Remember when the Tower of Fate collapsed at the end of Shovel of Hope? That wasn't because of the amulet's destruction. That was because Mona and Plague Knight blew it up with the ultimate potion.
Specter of Torment has one where you fight SHIELD KNIGHT. DURING A FLASHBACK SEQUENCE. And it's actually tough, since she's the only character that can auto-block almost all your attacks.
Specter Knight's final boss, Nightmare Reize, has Specter Knight grind on rails over a bottomless pit to even catch up to him, as he is constantly ahead of you. It's almost like a set piece from Sonic The Hedgehog in how fast pace it is. Oh, and of course the rails start falling as the boss gets lower health and you have to HOMING ATTACK across pits at high speed to make it over and finish him off. Did we mention you get a cool sounding reprise of Fighting With All Of Our Might during the whole thing?
This one is minor, but Specter Knight telling Black Knight to "Steel thy shovel!" before their second fight in Specter of Torment. Maybe that's where Black Knight got it from in the first place.
Obtaining the Judgement Orb in Specter Knight's campaign is a hell of a moment when you realize that it's the floating lunge attack he does as a boss.
If Specter Knight collects every single skull, Red implies that despite being under her control, Specter Knight is plotting against the Enchantress.
For as big of a self-centered dirtbag as he is, there’s something to be said about King Knight’s campaign in “King of Cards.” He travels the land in search of a way to be recognized as a true king while all his “subjects” more-or-less just tag along for the ride under the assumption he’s...basically the exact opposite of who he really is. King Knight manages to put together a sizeable group of subjects including the actual king as a blacksmith!
Speaking of King Pridemoor, his boss fight is certainly one to remember. You would think the king would be easy to fight right? Wrong! Turns out King Pridemoor has a suit of mech armor on standby in case he has to get his hands dirty! It’s basically like fighting a more powerful, beefed up version of King Knight! After the king joins the crew of the airship following King Knight, he returns to his old job as a blacksmith. This means the king most likely built that hulking suit of armor himself! Talk about Royals Who Actually Do Something!
And how does King Knight fight? By sheer brute force! Shovel Knight has trained in Shovelry, Plague Knight is a mad genius explosives expert with a seemingly infinite supply of different bomb types, Specter Knight has supernatural powers and skills from his days as a wandering warrior. King Knight? There’s no evidence of formal training and nothing that says he had a teacher. Meaning every skill he has in combat was self taught! He may be seen as the weakest of the Order of No Quarter, but by no means is he weak!
This is backed up by the used workout equipment in his bedroom. This includes a hanging punching bag that is clearly worn out from overuse. This should give you a pretty good idea of how seriously King Knight trained to become the fighter that he is!
One of the first scenes shown was his intrusion into Pridemoore Keep, wherein he singlehandedly shatters the gate into splinters and tears through the castle to personally challenge the King to a duel.
Mr. Hat shows off a new hat in King of Cards; After getting him down to a certain threshold, he proceeds to pull out a crown of his own, and based on his weapon for this set of powers, it seems he swiped it from King Arthur.
