Invisible

The Invisible is a sword wielding Pureblood Heartless from Kingdom Hearts. It appears in End of the World and Olympus Coliseum. As the name suggests, it has the ability to become invisible. One of its special attacks includes throwing its sword in the ground, while the main body turns into a ring of dark fire surrounding either Sora, Donald or Goofy. Once the time is up, the curse explodes, dealing large damage on any member of the party. Like Angel Stars they have a high rate of dropping Gale once you defeated them.

Kingdom Hearts
''Heartless wielding a large sword. These winged Heartless can move freely through the air. Besides their sword, they attack with their tail and wings. With their high attack power, they often defeat their foes quickly.''

Appearances

 * End of the World
 * Olympus Coliseum

Abilities
They fire dark energy every now and then. Of course, they will slash at you, but thier final attack is to put thier sword in the ground, then trap you in a ring of fire. This can be avoided by jumping, using Superglide or Dodge Roll.

Trivia

 * The kanji written on its blade means hard shell, or core, which probably is meant to say "hardcore".
