Kairi, later Xion, later Kairi Heartwarrior, is a major character in John Smith 10: Kingdom Hearts. Through the course of the series, she went from Original Kairi, then to Xion, then to Kairi Heartwarrior. She also appears as a main character in Omnimania.
While at first it seemed like she was to be portrayed into the same Kairi back in Kingdom Hearts, that changed over time, and her role was filled up quickly, becoming successfully one of the two main characters of that series.
She is the first originally off-dimension character to become a main character.
She is going to be a main character for the rest of Kingdom Hearts.[1]
The name Kairi Heartwarrior was suggested by Ahmad, and approved by Dioga.
Spacewalker State is based off the Avatar State from the Avatar: The Last Airbender series.
Kairi is a member of the superhero group called ry:Female Her, consisting of the alternate forms of John. She is one of the main characters of the team, as well as the newest. She was originally experimented on by the Organization.
