The first time we see Marron she is 3 years old. She is the daughter of Krilln and Android 18. She is unaware that her parents have powers, until they begin sparring in preperation for the World Martial Arts Tournament. This is because she never saw them fight. Anyway, she attends the World Martial Arts Tournament to watch her parents fight, and is surprised by how easily her "daddy" defeats a man much bigger than him! Marron never fights, even though she is probably quite capable, because she has 2 of the strongest people on earth as parents! As Marron grows older she gets a nose, and her hair color, and eye color changes (weird eh?) Anyway, she hangs out at the Kami house with her father and mother for most of the series. She dies only once throughout the series.
Marron doesn't have a nose when she is born (Krillin trait) she does when she grows up
Marron's eye color changes.
Marron likes the company of her parents (unlike most teens :p)
Marron means 'chestnut' in Dainish, as 'Kuri' (in Kuriririn) means Chestnut in Japanese
Marron was NOT named after Krillin's first girl friend, in the original mange Maron (Krillin's g/f) did not appear, and Marron (his daughter) did
