Action Jennys were evil drones created by Krakus and sold as seemingly "innocent" toys. They appeared in the episode Toying With Jenny. As drones, they were equipped with highly developed recovery capacity after being destroyed, and creative ways to destroy, capture, battle and torture, according to the theme of their design. However, all of them presented the abilities of flying, and lengthening their arms, legs and necks. Due to the large numbers of Action Jenny dolls produced and sold, they could easily to became a very effective plague. One of their strongest points was the unique methods of attacking created for each different type/design of Action Jenny doll.
