Bio: Watch out!  It's her time of the month every day!  Chichi is in a word, a mom.  To Gohan, that is.  She does all the motherly things she should, such as force her son to do homework constantly, force him to stay home to do his homework, and generally force him to do homework until he dies of exhaustion.  She also does her fair share of yelling at her husband, as he seems to never be allowed to leave the house.  Although a complete and total bitch, she does get nicer toward the end, especially when Gohan and Videl are going out.
