Goku:Goku is the main character of Dragonball Z. He is a Saiyan who was sent to Earth to kill everybody on it so it could be sold. However, he fell down a cliff when he was a baby and hit his head and doesn't remember anything. Now he defends Earth. He married Chichi and had two sons, Gohan and Goten. He didn't know he was a Saiyan until he was told by Radditz in the beginning of DBZ. Even though he is a 3rd class Saiyan he is usually the strongest character for most of Dragonball Z, even more powerful than Vegeta who is the prince of the Saiyans. Goku got his tail surgically removed when he was a baby so the light of a full moon no longer turns him into an Oozaru.
Goten:Goten is Goku's second son. He doesn't appear until later on in the series and in DBGT. He is Chibi Trunks' best friend. He looks just like Goku and likes to fight.

Marron (Krillens girlfriend):
Marron was Krillen's girlfriend at the time of the Garlic Jr. mini saga. Marron was more of a slut than anything else as not only was she Krillen's girlfriend she was a couple other dozen guys girlfriend. She was also a bit ditzy. Like your dumb blond (Even though her hair was blue). When first seeing her you'd first think it to be a much younger Bulma.
Marron (Krillens daughter):
Marron Krillens daughter looked a lot like her two parents android #18 and Krillen. She had Krillen's eyes, android #18's hair, and andriod #18's mouth. She doesn't play a big role in the series.
