Maron appeared in the Garlic Jr. Saga of Dragon Ball Z, and was introduced as Krillin's first girlfriend. She has a strong resemblence to Bulma and has a carefree attitude. Maron is mainly attached to any cute guy around (which is why she was flirting with Yamcha at the beach party).
Maron and Krillin lasted only through the Garlic Jr. Saga, then she returned for the Cell saga, but Krillin had over time found the love of a young blonde enemy, Android 18. They got married and had a daughter, which Krillin names Marron out of respect.
