Iterations of Kai and Kia as the appear in Kingdom Hearts

Kai (as Rhapsody) and Kia are unseen characters yet to have made a full appearance in the ORPG, Kingdom Hearts Legacy.

Rhapsody is a lone knight from the World That Never Was. He is aptly named the Beast Knight in due to his sheer strength easily comparable to that of a monster but wields it with the skill of a hero. He wears a helmet to cover up his bestial nature. His interesting air had caught the attention of Kia, whom seems to follow him wherever he goes when she's bored

As for Kia, she is actually a native resident of the Realm of Darkness. Neither Heartless, Unversed or Nobody, she watches events unfold from the shadows. She tires of people labeling the darkness as evil. Despite her casual, normal tone of speech, she knows quite a bit about both the light and darkness and how they work.

Both characters retain their original powers and weapons and as such, they do not wield Keyblades. However, their fighting styles are different. Kia this time around is much more active with her magic powers, aligned towards darkness elemental techniques and Rhapsody actively counters attacks.
