In Dragonball Z, Trunks showed up in the Cell Saga, as Future Trunks to give Goku heart medicine so he wouldn’t die of a heart attack. A year before Future Trunks went back to his own timeline, Chibi Trunks (which is normally called just plain Trunks) was born. And then a year after Trunks was born, Goten was born. And Goten and Trunks were the best of friends. They even fused to make Gotenks in the Buu Saga. - In Dragonball GT, Trunks is 8 years older than Pan making Trunks…(I hate math, but adding is still easy)…20!!!! WOW, never realized how old Trunks is in GT! Now in GT Trunks, Chibi Goku, and Goten were going to hunt in the universe for the Darkstar Dragonballs. And then Goten left to go talk to his girlfriend, until Pan snuck aboard and pressed the launch button and what I’m thinking Trunks HAD to be mad, since his best friend wasn’t going. Well, back to the bio! Trunks’s highest powerlevel is 63,800,000 but that’s cause he turned Super Saiyan!
