All right let's face it, the girls in DBZ are weak, panicy, and over protective. Not exactly hero's. But they must be given credit for the simple fact that through thick and thin ... they never leave their husbands.
Chichi meets up with Goku as a small girl and makes him promiss to marry her. Later on thy meet again and fall in love and Goku finaly take her up on that offer. Together they have two sons: Gohan, and Goten
Chichi may look insent but threaten her family and you better watch out. She's very over protective, but she meens well. Her dream is for her little Gohan to become a scolar.
Bulma is the first to meet Goku. They team up to find the dragon balls together. On the way they run into a guy named Yamcha and Bulma falls in love with him. From that piont it's always asumed that Bulma would marry him. However that's not how it happened.
Bulma is the techincal genius. Among her achevments are; the invention of the dragon radar, the sucess of capsil corp. and my favorite with no prior knowlege of such things, she totaly reconstructs Raddiz's scouter.
At the begining of what I believe is the cell saga we find Bulma pregnant! aAnd with Vegita's child at that! Honestly I think they deserve each other. Any way together they have two childeren; Trunks, and Bra.
