One Heart

One Heart (ワンハート) is a Team Attack that appears in Kingdom Hearts III Re Mind. It allows Sora and Kairi to team up and use continuous attacks to damage an enemy while airborne.

Mechanics
In Kingdom Hearts III Re Mind, One Heart is a Situation Command that is used by either Sora or Kairi. When used, Sora and Kairi will dismiss their Keyblades and hold hands to make a pair of huge wings of light appear on their backs. They fly towards Xehanort and make continuous attacks by spinning their wings, showering feathers made from shared memories everywhere.

Kingdom Hearts III

 * One Heart is available during the the fight against Armored Xehanort.

Trivia
In the Chinese mythology a pair of one-eyed birds with only one wing,, can only fly together by acting as one, thus representing husband and wife.
