When Sonic the Hedgehog and Monkey Khan approached the city, the Yagyu Clan was ordered by the Dark Egg Legion's Kommissar, Lien-Da to fight them off while they stayed in a safer position as support. They proved to be formidable opponents against Sonic and Khan, especially when assisted by the Dark Egg Legion troops. After the Iron King joined the battle, the Yagyu forces became overwhelming, and the two heroes were forced to retreat. (StH: #202)
