Kailani was a Ga-Matoran.
Nothing is known about her life in Metru Nui, except that she was eventually forced into a Matoran Pod during the Great Cataclysm and later rescued and awakened by the Toa Metru.
Kailani lived and worked in Ga-Koro as a Craftswoman. She was also rebuilt at the Kini-Nui into a stronger form.
Return to Metru Nui
She has since returned to Metru Nui and helped to rebuild it until the Staff of Artakha repaired the rest of the city. She was also present during the ceremony for Matoro at the Coliseum.
She later evacuated the Matoran Universe onto Spherus Magna with the other Ga-Matoran and the Water Tribe in the Great Sea.
