Note: This character is not to be mistaken with the game SonSon.
SonSon III (ソンソン) is a little monkey girl who is the granddaughter of a character named SonSon, who starred in an old Capcom game with the same name, SonSon. She is an original fighting game character created for Marvel vs. Capcom 2: New Age of Heroes. She tries to find out why her village was struck by an unknown illness.
Sonson and her grandfather are both based on Sun Wukong, the main character of the Chinese novel Journey to the West. Several of her attacks are derived from the series, such as the size-changing bo staff, Wukong's ability to replicate himself using the hairs of his body, or SonSon trying to cook her opponent in the Shinka Hakke Jin and turn them into sake.
