DBZ History
At the age of 20, Chi-Chi gives birth to her first son, Gohan. Four years later, during the time of the Saiyan conflict, Chi-Chi's husband Goku was slain in battle to defeat his brother Raditz, and her son Gohan was kidnapped by Piccolo to be trained at Break Wasteland for the battle with the remaining Saiyans that were on their way to Earth. Chi-Chi found this out after going in rage at Kame House.
One year later, she returned to Kame House and witnessed the battle against the Saiyans on Fortuneteller Baba's Crystal Ball. After the battle, and Vegeta's retreat, she came with the rest of the Z Fighters' supporters to find her son, and recently revived husband had survived the battle, but both badly injured, and Gohan unconscious after transforming into a Great Ape. She completely ignored the near to death, broken Goku, and looked after her son, while angry at Goku for letting their own child fight against the Saiyans (although it was a decision which had been made by Piccolo, not Goku).
Chi-Chi, Master Roshi, Oolong, Puar, and Yajirobe as they prepare to leave for Namek Chi-Chi took care of Goku in Wukong Hospital while Gohan, who was healed, went with Krillin and Bulma to Piccolo's homeworld planet Namek to use the Namekian Dragon Balls to revive the fallen Z Fighters from the battle. Once Goku was healed and left to meet up with them on Namek, Chi-Chi gathered Master Roshi, Oolong, Puar, and Yajirobe to try to use another one of Dr. Brief's spaceships to fly to Namek to rescue Gohan and the others from the threat Frieza which was on Namek. Instead, the ship did not work so they were forced to stay behind on Earth and wait. Chi-Chi is reunited with Gohan when everybody on Namek except Goku and Frieza were transported to Earth. Chi-Chi witnessed Porunga revive the fallen Z Fighters and tell them that Goku is still alive and on his way back (as well as gave Master Roshi an implied threat to stab him with a sword after the latter, in frustration, stated that Goku's reason for not returning immediately is because he is scared of Chi-Chi, who is the one being stronger than a Super Saiyan).
