Koukuji_Family is rapidly running out of header jokes, so... yeah
Daughter of the Ox King, and future wife of Goku, in addition to being a mother of two, there... isn't much else to say about Chi-Chi that folks don't already know. And if you don't, go watch Dragon Ball. Do it now. And then a bit of Z. And then Super when it starts. And maybe GT.
In her youth, Chi-Chi was quite shy, and often had marriage on the brain. She's very sweet, even considered pure of heart, despite being the child of the "terrifying" Ox-King. In battle, she's tends to be quite frightened, usually seen sobbing after defeating her foes. Despite her appearance, she's got an impressive array of attacks. She can fling the blade on her helmet at her enemies, or even fire beams out of it.
Once she got older, she started to change. She became a little more pushy, a bit naggy, and incredibly overbearing and overprotective of her children while dealing with her husband's goofiness. She's also considered to be one of the strongest women in the world despite being a human without any kind of enhancements.
...On the note of 'enhancements', this Chi-Chi is a tiiiiny bit different from the one we all know and love. Spending time with Goku in her younger days had caused some of his habits to rub off on her. Namely, her appetite started to grow. Chi-Chi started snacking more often than usual, and it started to affect her figure growing up. She got a biiiiit... thicker.
Her new snacking habit only got worse into parenthood... With Goku carting Gohan along to train or battle planet-busting evil, a mother starts to worry. And when this mother worries, she starts seeking snacks. ...A lot of snacks. So her 'thick' figure became generally, well, fat. And if some poor soul, probably Krillin, says or does the wrong thing around her, they'll probably end up as comfort food themselves...
Both young and adult versions are available for stuff.
...Or, if you're feeling so inclined, you can have a third variant of Chichi swollen with baby.
