He first appears on the serie during the Android Saga, he is still a baby, and he is always being carried by Bulma,
or Yajirobe (sometimes during the saga).
When he is 8 years old he appears in the series again; he and Goten are best friends, since they share very
little age difference. Trunks loves fighting and he likes taining with his dad. He turns SSJ at a very young
age, just like Goten.
He faces Goten in the 25th Budokai and wins, Goten gets reallly mad at him, and Trunks tells him that he can
have any 3 toys he wants if he changes his attitude, which of course Goten accepts. Later in that same Budokai, he and Goten attack
the fighter known as Mighty Mask, so they can use his costume and fight in the adults Budokai.
Trunks and Goten fuse to form Gotenks, who was very usefull whn fighting Majin Buu.
Ten years later he also takes part in the 26th Budokai.
In Dragonball GT he, along with Goku and Pan, travel to space looking for the Black Stars Dragonballs
He once dresses like a bride to get a Dragonball.
