C-13, died in 767, is a cyborg created by Dr Gero. He(it) is with C-14 and C-15 one of the three androids of the movie Ball Z Dragon: the Offensive of the cyborgs.

He(It) is a member(part) of the last creations of the doctor, and is activated after his(its) death. Following the example of C-17 and C-18, he has a very human physical appearance but is a completely mechanical being, as C-16. His(her,its) look is similar to that of Trunks, with a yellow / beige vest, a green pants with straps(suspenders), shoes as those of Trunks, earrings and a cap carrying(wearing) the symbol of Red Ribon. His(her,its) hair are white and long.

As his congeners, he aims at killing His Goku. He(it) fights against this one by taking the advantage until the transformation(processing) of His(Its) Goku in Great Saiyan. Vegeta kills C-15 and Trunks kill C-14. C-13 absorbs then batteries(drum kits) and chips of two other cyborgs to be transformed into Super C-13, a version of him more massive, the skin turns to the blue(bruise) and its hair raise themselves(draw up themselves) by taking the shape of those of Vegeta and orange color. He(it) overcomes easily His(Its) Goku, Vegeta, Trunks and Piccolo but does not resist the power of Great Saiyan (having absorbed Genki Dama) and is killed by His(Its) Goku which makes him(her) burn hands on Genkidama to pierce him(it) then with bare hands.
