The Phantom is an Emblem Heartless that is found in Kingdom Hearts. It is one of the bosses at Neverland. While the Phantom is in possession of the Clock Tower, the hourly treasures cannot be obtained.
The 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, Donald, Goofy, 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.
The Phantom wears a long, tattered, black cloak with long sleeves that gradiates into cyan from the waist down. It has a long, pointed hood and it does not seem to have a face or body of any kind. Only its clawed, five-fingered hands are visible, but even they seem to be wrapped in the cloak. The apparent source of its power is an orb that contains its heart in the lower section of the cloak. This orb glows in a different color—red, blue, yellow, and white—depending on the type of attack it is currently vulnerable to. The orb can also disappear entirely for short periods of time. The Heartless emblem is displayed on its back.
In Kingdom Hearts Final Mix, the Phantom is largely unchanged, though its cloak is now predominantly white with black sleeves decorated by a flame-like pattern.
The Phantom's name is a reference to its eerie, ghost-like appearance.
Because it is essential to be able to consistently freeze the clock, the party should prepare to boost their MP regeneration as much as possible. Goofy should be in the party equipped with MP Gift, Sora should equip the best MP-boosting equipment he can, and all characters should have MP Rage, MP Haste, and plenty of Ethers equipped. The player should also fully upgrade the three elemental spells to deal as much damage as quickly as possible.
The Phantom will only sustain damage when the glowing orb beneath it is visible. Even then, Sora will only be able to damage it in a specific way, determined by the color of the orb. Each time the orb is hit, it will change color. Once struck three times, it will disappear.
Following his victory, Sora's Stop magic will be upgraded.
