Healer is a white female Kirby that went with Kirby and Meta Knight through the Dimension Gate to find King Dedede in Kirby Dimension Gate. While there, she uncovered some robes of a White Mage, which she wore and gained the ability to use healing magic. She is one of the only non-playable Kirby series characters.
Healer can fly like Kirby, and can also spawn Copy Abilities for the characters to use. Her main ability, however, is to heal characters. She can also teleport around, which she does often as she appears before most boss battles in the game, and at checkpoints throughout the levels.
