SonSon III is a playable character in the fighting video game, M.U.G.E.N Trilogy. She is the granddaughter of the original SonSon and was confirmed on April 15, 2015 along with many other characters who appear in the Marvel vs. Capcom franchise. Mayumi Iizuka (who also voiced Tron Bonne and Mononobe no Futo, Japanese) and Alex Cazares (who also voiced Suwako Moriya, English) provide the role for SonSon III in this fighting game.
SonSon III is a little monkey girl and the granddaughter of the original SonSon, who she's named after in spite of being female. Both are based on the Monkey King, Sun Wukong (known as Son Gokū (which refers to the character's name from the Dragon Ball universe) in Japanese), the main character of the Chinese novel Journey to the West, and utilize several elements and items from the series, such as the size-changing staff, or SonSon III trying to cook her opponent in the Shinka Hakke Jin and turn them into sake.
At the time the ancient Abyss awakes from its slumber, the village where SonSon III lives is suddenly afflicted by a strange disease. With her grandfather's Ruyi Jingu Bang staff she inherited on hand, SonSon III ventures outside in order to discover the source behind this unknown illness. During the ending's ride back home on Ruby Heart's ship, she can be seen onboard happily hanging out with Marrow.
In Ultimate Marvel vs. Capcom 3, SonSon III (spelled "Son Son") makes a cameo in the Days of Future Past stage, featured in a giant wanted poster on the background, with a "Slain" bar over her mugshot. But, in Marvel vs. Capcom: Armageddon, she makes a fierce return with new special moves, a level 3 hyper combo and her own music theme from the SonSon arcade game.
