Dragon Ball By Gautam Bala: C

Chi Chi

Chi Chi, known as Chi-Chi in the Viz manga, Chichi in Japanese versions, and Milk in Latin-American TV, is the wife of Goku and the mother of Gohan and Goten. She is very protective over the well being of her family, and wishes to remove them from Goku's lifestyle of fighting and constant conflict. She attempts to have Gohan focus on studying during his childhood, but this is interrupted by the constant threats to Earth. She later relaxes with Goten, even training him herself. As the daughter of the Ox-King, she is very strong in her own right, having easily made it to the quarter-finals of the 23rd Tenkaichi Budokai. She and Goku first meet as children, and Goku promises to marry her, thinking marriage is a kind of food. She later confronts him to have him fulfill the promise, despite the misunderstanding.

Cell

Cell (Seru) is the ultimate creation of Doctor Gero. He is an artificial life form created using the cells of several characters from the series, including Goku, Piccolo and Frieza. As a result, Cell is able to perform techniques such as the Kamehameha, a powerful energy blast which he gains from the cells of Goku. In creating the character of Cell, Toriyama tried many different designs before finally settling on the one used in the series. Cell evolves several times throughout his appearances. He originally evolves from a cocoon-like form into his first "Imperfect Form", which is insect-like in appearance. Both his first form and his second "Semi-Perfect Form" have a long tail that ends in a stinger-like appendage and allows it to absorb other organisms. The tail recedes under his wings in his final "Perfect Form", and he can use it to spawn Cell Jr. (Seru Junia), a minuscule child-like version of himself.

Requiring the androids #17 and #18 to evolve, he finds out that they are already dead in his timeline, so he kills the Trunks of his timeline and uses Trunks' time machine to travel back in time. He eventually absorbs both after many battles and ascends to his perfect form. He decides to hold the "Cell Games", a tournament in which he fights against the Earth's fighters until there are none left, resulting in Earth's destruction. Cell manages to defeat Goku, but he is eventually killed by Super Saiyan 2 Gohan. Cell appears in Hell in Dragon Ball Z, and makes a few appearances in Dragon Ball GT.

Cyborg Frieza

It is Frieza’s last form. She was healed by her father after the battle of Nemek with Goku. She was killed by Trunks.

Chiaotzu

Chiaotzu (Chaozu) is a small human that resembles a doll with white skin, red cheeks, and one hair under his hat. Though he is not physically strong, he is skilled with psychokinesis and telepathy. He first studies under the Crane Hermit with his close friend, Tien Shinhan. After Tien realizes that the Crane Hermit's teachings are wrong, the two leave him and join with Goku and his companions. He continues to support Tien throughout the series, even going as far as self-destructing on Nappa in order to attempt to save him. After the Saiyan Saga, Chiaotzu is generally no longer involved in battle.
