This is Bulma Briefs, from Dragonball Z. She's the eventual wife of Vegeta, though she's definitely not there yet, and mother of Trunks and Bulla Briefs. She's the daughter of the founder of Capsule Corp, Dr. Briefs, and she's an inventor and engineer in her own right. She's also very badass. She's from the three year period between the defeat of Frieza and the Androids, so she hasn't had any kids yet, but she and Vegeta are getting to be friends.
