In Half a Mask of Kung-Fu, Kuro's mask was put on sale by a man called Alfie on www.alfiesantiqueauctions.com. It was then bought by Valmont. The mask was split in two by Hak Foo, Valmont wearing half of it and Jade the other. At the end of the episode, Jade removed Valmont's mask and Valmont removed Jade's.
In Ninja Twilight, after the nine masks was joined together, all of the Oni generals were freed and tried to destroy the world.
