Yagyu Clan

The Yagyu Ninja (also known as the Yagyu Clan) was a group of bat-like Mobian ninjas who were infamous for plundering and terrorizing villages in the Dragon Kingdom. For over fifty years, the Yagyu Ninja attacked and pillaged goods from Leung Kar village, often stealing things from the Temple of the Golden Lotus. However, in 3236 the Yagyu were stopped from stealing goods by Monkey Khan. Khan, along with Liu Fang and Liu Chi Me later tracked down the Yagyu to their headquarters and attacked them, though subsequently fell into a trap set up by Lord Yagyu. Khan and the others discovered the loot stolen by the clan, only to be attacked by a robot dragon controlled by them. Monkey Khan managed to reprogram the dragon to attack the clan members, forcing them to flee. (SSS: #8)

Nearly two years later, members of the Yagyu Ninja travelled to New Megaopolis along with the Iron Queen and King to usurp the Eggman Empire from the now-insane Dr. Eggman, with help from Snively. (StH: #200)
