Trunks

Trunks is the first child of Vegeta and Bulma. Trunks gets his Tapping Sword from Tapion. Trunks builds a time machine to travel into the future. He finds out that Goku dies from a heart disease. So Future Trunks returns to the present and gives Goku his heart medicine so he will not die. Then Cell, a creature that Dr. Gero makes steals the time machine and travels into the future to asorb artificial humans #18 and #17. Then he turns into Perfect form Cell. Future Trunks defeats King Cold and Freeza.

Chibi Trunks

Then there is also Chibi Trunks, who always hangs out with Goten. He is like a minature Trunks that has an oversized sword. Chibi Trunks always fools around. He is one year older than Goten. He turns SSJ-1 at a young age. I think it is 7. He fights Broli one time and then he turns into a teenager when he is in the GT series. He has a sister named Bra. His mom is Bulma, his dad is Vegeta, and his grandfather is Dr. Briefs.
