Sisudatu, also known by the nickname Sisu, is a fictional character appearing in Walt Disney Animation Studios' 59th animated film Raya and the Last Dragon (2021). Created by screenwriter Adele Lim, she is voiced by American actress and rapper Awkwafina. She is described as the last dragon in the land of Kumandra. To escape the Druun, the monsters that once threatened Kumandra, Sisu compressed his magic into a gem. Humanity then fought for the gem and broke it, leading to the Princess of Heart Raya seeking her help to banish the Druun once again.
