Sisudatu, simply known as Sisu, is the titular deuteragonist of the 59th Disney animated feature Raya and the Last Dragon.
She is an ancestral water dragon who has been dormant for 500 years after her family sacrificed their lives to stop the horrific Druun creatures that threatened the land of Kumandra. Upon awakening, Sisu becomes the warrior princess Raya's best friend and travel companion to save the world from the return of the Druun while trying to mend the now shattering world.
She was voiced by Awkwafina.
