Heartless Bosses (KH III)

This is a list of all major Heartless bosses in the game, Kingdom Hearts 3: Reconnect.
 * Crystal Titan - Rourke's Heartless form after getting crystallized by the crystal knife. It's about as big as the Groundshaker. He is capable of creating large crystals for projectiles in his claws. He is weakened by thunder spells.
 * Hellfire Heartless - A gargoyle wyvern heartless that was summoned by Frollo's lust for vengeance upon Quasimodo. This heartless flew on wings adorned with flames and blasted fire from it's mouth.
 * Frost Wyrm - A dragon heartless that was created by the Horned King to aid Jadis the White Witch in Narnia. Its special attacks revolve around ice and hail.
 * Captain Flint Dark Galleon - The soul of the wicked space pirate has fused with his ship to form a large Heartless ship after Captain Hook activated the laser detection trap. The Dark Galleon had a giant version of Flint's skeleton wielding a laser cutlass fused to the ship, while various cannons blasted out fireballs to attack our heroes.
 * Treasure Keeper - A heartless that was attracted by John Silver's greed and Scroop's darkness, Captain Hook sent this Heartless to keep us busy while he activated the trap in order to create the Dark Galleon.
 * Insectikiller - Hopper's anger over his humiliation led the Heartless to consume his heart and turn him into one of them. It was in this form did Hopper unleash his dark powers on Sora and Flik. As the Insectikiller, he could fire lightning bolts from his mandibles, slice up wind slashes from his wings, or rapidly punch our heroes at mach speed.
 * Sinner's Hand - A heartless powered by the heart of Dr. Facilier that was summoned by the Friends on the other side to do battle with Sora and Tiana. It was a large shadow demon with lots of eyes, a shark-like mouth, plenty of color bands, and a long tongue. It's evil powers came from the shadows, but it was quickly defeated with a light blast from the keyblade.
 * Heartless Nome King - When the Nome King feared his defeat after the Scarecrow was freed, the Heartless fused with him to become a massive rock monster that wanted to eat every one of us to preserve itself. Only Billina's egg could harm it, which is what Sora used to destroy the Nome King forever.
 * Jafar's Heartless - In order to provide backup for himself, Mozenrath resurrected Jafar as a large cobra heartless to do battle with us. In this form, Jafar looked like his cobra form, only with spines across his back and two wings, as in he looked like Maleficent's dragon form.
 * Cursed Carriage Heartless - When Lady Tremaine turned Lucifer into a coachman to try and get rid of Cinderella, the wicked cat rode a pumpkin that had been transformed with the powers of darkness into a Heartless version of Cinderella's pumpkin coach. It looked similar to the Cursed Carriage unversed that Aqua once faced, only with Heartless eyes, design, and symbol to differentiate it.
