Blue Rhapsody

Blue Rhapsody are enemies from Kingdom Hearts and Kingdom Hearts: Chain of Memories.

Blue Rhapsody are a member of a strange family of artificial Heartless. Almost every Heartless in the family (with the exception of Wizards and Bookmasters) shares a common trait: They look very much like Vivi, and all have names referring to their color and a form of music. A rhapsody is an instrumental composition of irregular form often incorporating improvisation.

Blue Rhapsody tend to fly lower than their relatives. They utilize Blizzard magic, and in compensation they are weak to Fire magic.

An interesting paradox, the plurl for Blue Rhapsody can be both "Blue Rhapsody" and "Blue Rhapsodies."

Kingdom Hearts
''Spellcasting Heartless. They approach their enemies by bouncing about and attack with Blizzard and absorb blizzard attacks.''

Kingdom Hearts: Chain of Memories
''A magic-wielding Heartless that drifts through the air. The Blue Rhapsody attacks with Blizzard once it's close enough, and absorbs Blizzard damage.''

Trivia

 * The Silver Rock from Kingdom Hearts 2 attacks a lot like a Blue Rhapsody.
