Deed (ディード Dīdo) is a female Combat Cyborg first introduced in StrikerS.
Along with Otto and Sette, Deed is one of the last Numbers to be completed. She and Otto were created using the same genetic material as a basis. That plus the fact that they both belong to the same taciturn type makes Deed and Otto very close to one another. When directing herself to her older sisters, Deed always presents a very polite behavior. On another note, Wendi dislikes her and Otto because of their always-serious personalities. Said seriousness is believed to be the result of manipulation carried out by Quattro upon the final batch of Numbers to remove "excess elements" from their composition.
