Unmarked spoilers below.
- During the final battle, Magolor attempts to actually block Kirby's Ultra Sword. Kirby wins the power struggle as before... and then hits Magolor. And again. And again. AND AGAIN. And then, to finish him off, Kirby lifts up the regular ultra sword, makes it grow HUGE, and swings it in slow motion as the screen whites out...before floating to the ground, twirling his sword like a badass, and striking a pose. And then Magolor BLOWS UP. Deluxe adds the yell Kirby would do in later games' final boss finishers starting with Planet Robobot to the initial struggle, making it even more awesome in that version.
- Then Magolor gets back up because of the Master Crown. Now with even more power in his repertoire, he showcases many destructive moves, including a giant laser, a black hole, and his own versions of the Super Abilities. Kirby and co. eventually defeat Magolor after a hard struggle... but Kirby's Dream Collection later shows that he even survived that, too! Sneaky as he is, he's one tough magician, for sure.
- The "Final Battle" cutscene. Magolor is throwing energy spheres at the crew as they ride Landia through space, and Meta Knight just bats them away with his sword like they're nothing. He even flies in front of Kirby to protect him before getting shot down.
- In the last leg of the last stage, you're given an Ultra Sword in a room filled with minibosses. As if effortlessly destroying almost every miniboss in the game wasn't awesome enough, to reach the Sphere Doomer interdimensional tunnel, you get to split a volcano in half. It also doubles as a Funny Moment if you're lucky enough for Kirby to use the giant fish or, to a lesser extent, the Paper Fan of Doom for it. Nothing is more glorious than seeing Kirby cut a volcano in half with a giant tuna or flimsy fan.
- A minor example of nostalgia from the last stage: at the very end of the stage, you can find a secret area containing stars by flying up above the stage exit door and entering the background planetoid as a door; exactly the same secret used in Bubbly Clouds, from the original Kirby's Dream Land.
- You also get to destroy a spacecraft while riding a dragon and destroy a giant mecha piloted by a smaller mecha. Really, the second half of the game is just filled with moments of awesome.
- The first Disc-One Final Boss Grand Doomer. This guy doesn't appear until after a Victory Fakeout and gets his own boss theme that is nothing short of epic. You beat down the usual two phases each boss has had up to this point when he shields himself and starts summoning enemies. In the second set of them he spawns, you can get the Ultra Sword. Get it, and a fast paced remix of the Super Ability theme starts playing as you destroy the rock shield, slowly cracking it until it's completely gone. After four hits, you use the Ultra Sword one last time to finish him off in a five hit combo.
- In Extra Mode, the bosses are all upgraded by having more health and stronger, upgraded attacks, but are relatively unchanged. Except for the Metal General, who starts out this way... then reveals that it found a Humongous Mecha that resembles the Dedede Robo from Kirby GCN, at which point you fight two more health bars to take them down in a very impressive reference to Kirby 64.
- The Optional Boss: You get to fight Galacta Knight, the greatest warrior in the galaxy, again, and he's more powerful than before. Even better, if you have three friends, you can gang up on him with a four-on-one; a whole eight years before Super Kirby Clash did it!
- Even more than that, the start of the battle uses "Guardian Angel: Landia". Then, once you halve his health, the familiar Epic Riff begins and Galacta Knight comes at you with everything he has.
- Deluxe features a little easter egg that's sure to get any player even more pumped up for the fight. If Player 1 has selected Meta Knight or Dedede as their character, then "Guardian Angel: Landia" gets replaced with "Stage of the Partners Who Shook the Heavens". The game is giving the player their own Theme Music Power-Up before Galacta Knight's kicks in!
- Awesomeness kicks in when you perfect the "Samurai Kirby 100" subgame in Deluxe. The player's Kirby LITERALLY blasts through the other Kirbys!
- Deluxe features a brand new True Final Boss: a new, even stronger version of Magolor Soul in the True Arena, turning the original from what some deemed underwhelming and completely overhauling it into an absolute BEAST of an end boss. His attacks are even more extreme or used completely differently in a way that makes it harder to get breathing room...and then you realize his health is doubled. You empty out his health bar, him seemingly never using his Super Abilities this time...but then his eyes go out. The mouth eye shows up. He screeches in fury, a second health bar filling! Now you have his second phase with a complete health bar rather than half, plus even more attacks that incorporate Sand and Mecha which are also implied to be the Super version of those abilities. THAT is how you undo an Anti-Climax Boss!
- Of course, this isn't to discredit the regular final boss of Magolor Epilogue. After defeating the Crowned Doomer, pieces of the Master Crown surround the Gem Apple that Magolor had been recreating through the entire epilogue. What does that lead into? A fight against the Master Crown itself. A titanic Background Boss bearing the resemblance of a twisted, cycloptic tree demon, which attacks you with its full magical arsenal in the midst of the burning remnants of the dimension Magolor is on. Once its health is depleted, Magolor picks up a sword he finds lying in the rubble, transforms it into his own makeshift Ultra Sword and uses the blade to cleave the tree in half vertically, smashing the Master Crown to dust in the process. After all the pain the Crown put the player and especially Magolor through, it's cathartic as all hell seeing Magolor redeem himself through rejecting and destroying the evil artifact once and for all.
