Phantom

The Phantom (ファントム) is an Emblem Heartless that is found in Kingdom Hearts. It is one of the bosses at Neverland.

Journal Entry
''Ghostlike Heartless who haunted the clock tower standing far away from Neverland. Fluttering his eerie cloak, he cast a spell to take Sora's heart. Having no physical body, regular attacks were useless, but in the end Sora and company discovered his weakness and prevailed.''

Kingdom Hearts
Phantom emerged from the Final Keyhole after it was opened by the Princesses of Heart, and went straight to Neverland, where it possessed the Clock Tower. Tinker Bell discovered it there, and flew back to the Cabin of Captain Hook's ship, where Sora, his friends, and Peter Pan find her. She leads them back to the Clock Tower, where they are attacked by Phantom. However, after a violent battle it is defeated.

Strategy
Before this battle, ensure Goofy is in your party with the MP Gift ability equipped. Equip Sora with MP boosting equipment, and plenty of Ethers and Elixirs to ensure a plentiful MP supply. All party members should also have the abilities MP Rage and MP Haste equipped to increase MP gain.

The Phantom will only sustain damage when the glowing orb beneath it is visible. Even then, you will only be able to damage it in a specific way, determined by the colour of the orb: Each time the orb is hit, it will change colour. Once struck three times, it will disappear.
 * White color - Perform a physical attack
 * Red color - Cast Fire
 * Blue color - Cast Blizzard
 * Yellow color - Cast Thunder

Phantom has a few attacks, including a simple slash and a spell that sends out a puff of darkness to drain Sora's health. His main defense is to hide his weak point. When Sora defeats Phantom, he fades into the town and grants Sora a Stop magic upgrade.

Phantom will occasionally start the hands on the Clock Tower, and will start a 'Countdown Curse'. As the curse cannot be lifted, Sora's allies will be eliminated from the battle, one by one, ending finally with Sora. Whenever the hands of the clock tower move forward five minutes, the number will drop by one. Casting Stop on the hands of the clock will prevent it from moving for one minute real time. Any character eliminated by this attack cannot re-enter the battle.

Occasionally, the Phantom will fire an energy ball at Sora. If hit by this, he will sustain damage up to five times. This can be avoided by flying around to Clock Tower, with Aero(ra/ga) or by hitting the energy ball, which will vanish if done so.

Phantom can also perform a short-range, high damage slashing combo with his claws, though this is not as dangerous as his other attacks.

Following your victory, your Stop magic will be upgraded.

Trivia
While Phantom is in possession of the Clock Tower, the hourly treasures are unable to be obtained.
