Awesome Bosses/Kingdom Hearts

Sora and his comrades have fought against awesome bosses from many corners of the multiverse.

"Simba: TOGETHER!!
 * Xemnas from the first game's Final Mix. With the insanely creepy cutscene prior to the battle, and the awesome music, this battle was absolutely perfect.
 * Xaldin's boss battle. Sweet revenge...
 * Also 1st Xemnas, although they're all awesome. Then again, he is the Nobody of the greatest crowning boss ever, Ansem (who has the added bonus of awesome music). World of Chaos is the coolest, but easy.
 * It's no World Of Chaos, but the battle between Xemnas and his fortress is epic too, taking place inside Kingdom Hearts itself and being the last time you can use Donald and Goofy in the game, thus giving them a chance to go out with a bang.
 * The first one had Dragon Maleficent and Rikunort.
 * Also, Chernabog. Disney's Night on Bald Mountain, crap-your-pants scary Chernabog. Set to the original song.
 * Alongside Chernabog, there's also Maleficent, Monstro the Whale, and every other hellish spawn of Disney's sinister mind that robbed you of sleep for nights on end as a child. Regardless of how good or boring the boss fight is, you cannot deny that getting vengeance on just about every last one of those bastards was sweet.
 * Of course, once Final Mix+ came out, we got the TRUE Crowning Boss of Awesome. Roxas. Oh. My. God. ROXAS! Also gets points for having quite possibly one of the best/most heartbreaking battle themes ever, "The Other Promise."
 * Really, all the Organization XIII Data battles count. They may be hard, but they are awesome.
 * The final Xemnas fight in Kingdom Hearts II, when he finally faces off with you in person in the void after a long Sequential Boss fight. It culminates with two Keyblade masters wielders fighting off literally thousands of laser beams!
 * Despite being an easy boss, the battle against Dark Thorn is strangely awesome. Especially the music.
 * Same goes for the battle against Groundshaker. You're a tiny (and adorable) lion cub, it's a Heartless so massive it has a freaking tree growing on its back. The only bigger Heartless (so far) is the World of Chaos. Of course you feel like Superman after defeating it. The boss is the size of a freaking mountain. (Shadow of the Colossus, anyone?) And you're fighting this thing with Simba, who has one of the most Badass combo attack with Sora in the whole game.

Sora & Simba: * proceed to rip everything in the immediate area to shreds*"


 * Another sweet part of the Groundshaker fight is that one of the reaction commands is to get stomped on by his huge-ass foot and, as a tiny lion cub, block the stomp, throw off his foot, then vault into the air to smack it around and knock it out for a bit.
 * Darkside's first appearance as the first boss of the game. The dramatic music kicks in as Sora turns around to see his shadow rise up- and up, becoming an enormous, tentacle-haired colossus intent on kicking your clown-shod arse. Though it turns out to be an easy boss almost every time you fight it (Chain of Memories excepted), its entrance says very clearly that things are about to get serious. Sadly, the same can't be said for Roxas's own boss, the Twilight Thorn.
 * Twilight Thorn was pretty cool too though, especially when he knocks Roxas off the battle platform and into the air, throwing a huge ball of energy at him as he falls.
 * Most of the bosses in the series are some form of awesome. Nostalgic awesome for the Disney villains, "holy crap I feel like a badass" for Those Several Bosses, and just plain cool battles like the aforementioned Dark Thorn and Groundshaker... Every player's going to love at least one.
 * A crowning moment/shout-out for an Ascended Fanboy moment needs to be given to one Kurt Zisa of New York, for winning a Square contest "Name-in-Game", and having the Bonus Boss in Agrabah (Kurt Zisa) named after him. And the fight with the actual Kurt Zisa boss is incredible; On one side, Sora and his friends. On the other is Zisa, a giant snake-headed six-armed sword-wielding whirling dervish of a Heartless that can disable your magic, create a shield, chop you up like a blender, and jump on your head in an attempt to squish you. Truly, this is the hardest non-Sephiroth boss in the game.
 * As for Chain Of Memories, Captain Hook takes the cake. he uses cards like you, but by that point in the game you'll be used to fighting against card-users. You really have to think strategically, especially during the part where you have to play your cards later or he'll counter yours.
 * Far better than Hook is the final boss, Marluxia, especially in the Play Station 2 remake, in which he has three stages instead of just two.
 * Marluxia's first and third stages in particular.
 * Also from Re:Chain of Memories, Riku's battle with Zexion. Riku finally comes out of his Heroic BSOD, accepts the darkness as a part of himself without letting it control him, and he gets infinite Super Mode.
 * Also, pretty much any time you fight an Organization member the second time, especially Larxene and Vexen.
 * The bosses in 358/2 Days are all awesome, with the one absolutely stealing the show being the Infernal Engine. You rush through Beast's Castle, trying to find the unidentified Heartless, when all of a sudden, Beast is freakin' launched over the gates of his castle, landing in the courtyard all battered. This makes you start wondering, 'What the hell could take out the Beast? So, you rush out the gates, and then, Vim and Vigor kicks in, as a gigantic battering ram/siege tower rolls towards the main gates, and from that point on, you're basically reenacting the scene from Return of the King with Grond, if the heroes began viciously attacking it before it could reach the gates. It may be That One Boss to some, but to others, it cemented the game as truly magnificent.
 * In Birth by Sleep you fight at the same time. It bears repeating:
 * While not technically a boss fight, it may qualify as the most epic battle for II, if not the entirety of the franchise. On one side: Sora. Alone. On the other: 1,000 Heartless. ONE. THOUSAND. HEARTLESS. And your task? WIPE THE FLOOR WITH THEM.
 * Plus, Leon has shown you them at the beginning of the game and at that point, 20 of them could cream you. Now, you fake right, pick up Guardian and give it a keyblade suppository until it vomits a shoop-da-whoop lazor capable of putting you from 0 to 110. Awesome.
 * The only down point of the 1000 Heartless Battle is that the trailer showed a larger variety of Heartless, including several Behemoth Heartless. If only that had remained...
 * in Kingdom Hearts 358/2 Days. Pure awesome and the music in final stage is just so indescribable. Also, Ruler Of The Sky.
 * Another one from Birth By Sleep is Ven's final battle with Vanitas. Not only are fighting one on one with basically  but it also has one the most epic tracks in the entire series. Watch it in full here.
 * All Vanitas battles are awesome, though the final one above does take the cake. Coming in close second is
 * Terra's Final Boss fight. To clarify:
 * The Lingering Sentiment is That One Boss certainly, but that doesn't stop him from being insanely awesome. His relentless attacks are all the most unique and powerful attacks in the entire game, and ridiculous amount of health and defense makes it even better when you finally bring him down. And the song, Rage Awakened, makes the battle even more epic than it already was.
 * Luxord. He begins the battle by turning you into a die. A die that can't attack, save for a weak body blow, and can't move without using that same move. After you wait that transformation out, your main method of attacking Luxord is accepting his games of chance, Pressing /_\ To Not Turn Into A Card, and using the Action Command that gives you. And even after you've used the games to whittle down his health (or rather, "time." It's a Timed Mission for both you and him, and attacks speed the time up.), he spreads cards all over the floor, turns into one himself, and hides among the pile. For a gimmicky battle, it is kind of fun and exhilarating.
 * Sephiroth's fights, especially the one in the colosseum in the original Kingdom Hearts, where there's no weird, Filler plotline between him and Cloud to present it with; he just appears and awesomeness ensues.
 * In the second game, you start by pushing X to not die. Then the fight just gets faster from there. It isn't nearly as hard as the fight against Sephiroth in the first game, but for many gamers, it's much more enjoyable.
 * Master Control Program and Commander Sark. Such an awesome Shout-Out to the movie, and the MCP's constant taunting you during the fight ("IS THAT THE BEST THE USER CAN DO?")
 * BBS's Trinity Armor. Out of the Unversed boss fights, that one was the best; unlike the dumb old Guard Armor from the first game(and it's even stupider Reverse Armor form), it's Unversed counterpart is an actual Mech! Composed of three different Unversed! And a kickass Transformation Sequence! Not to mention it's one of the few boss battles in the game where you get allies for adding coolness; in this case, the OTHER two playable characters(so it's Terra, Ven and Aqua vs. Trinity Armor)! Easily one of the best boss fights in BBS.
 * The secret bosses of Birth By Sleep qualify as well;
 * in coded. Reasons:
 * It's an awesomer version of the Darkside.
 * Its second/third forms are a
 * Guardando nel Buio, Ansem's theme not heard since KH1.
 * He launches flying Keyblades at you from friggin' everywhere.
 * The, which transforms him into a  , letting you mercilessly beat the crap outta him.
 * Also from Re:coded, the Final Boss. This guy in a Black Coat's been screwing with you all throughout, and if you've played Chain of Memories, you're probably expecting Marluxia.   Cue Crowning Moment of Awesome as the man in the black cloack summons
 * Beating Scar in the Pride Lands, kicking the crap out of the guy for Killing Mufasa! Lying to Simba! And lying to the whole pride! WHOO!
 * Bonus points for taking place into the highest point of the Pride Lands with that epic scenery and The Encounter made it even more epic.
 * Hades. When you finally fight him, he's lost his temper. Auron is no longer his puppet, Hercules is over his Heroic BSOD, and now everyone wants to give Hades a piece of their minds. On top of that, their battle is also set to The Encounter. Heck, any Disney boss with this music could qualify for the nostalgia value.
 * Though he is That One Boss to some, Demyx's attacks, especially the guitar/sitar one-on-one quicktime reflex event, make him one of the most awesome bosses. Especially compared to his earlier appearances.
 * Barbossa, the first Live-Action Disney villain to appear in the series.
 * Either of the encounters with Braig in BBS. If nothing else for the awesome music, it shows just how powerful Xigbar was before he was even Xigbar.
 * The Hunter of the Dark, in Birth By Sleep: Final Mix, Perhaps the most badass Pureblood Heartless ever created. Helps that it's theme is epic as well.
 * Also, while not a boss, the swarms of Purebloods that are fought beforehand is what the Battle of the Thousand should have been.
 * Saix. This complete bastard arranged your girlfriend's kidnapping, has you Kneel Before Him, and then tells you to keep slaughtering Heartless for the Organization's Evil Plan. Taking him on as one of the last surviving Organization members and on the verge of a Villainous Breakdown, fighting this arrogant bastard tooth and nail and then triumphantly finishing him off is extremely satisfying.
 * Bonus Boss  in Kingdom Hearts 3D. Not only is he hard, not only is he a , not only does   play during this fight , but he's also one of the fairer secret bosses to recent date in the KH series, being hard because he is legitimately hard, not unfair hard. Quite a refreshing sight after the unfairness that is , especially the latter.
