Trunks was the second youngest to reach Super Saiyan at the age of 8. He is also very strong for a kid. He is not as lazy as Goten and has the potential. In DragonBall GT he gets pretty powerful and fights with Goku and Pan. Trunks is usually pretty quiet and obidient but when hes around Goten, things are different. Goten and Trunks are usually fooling around or are in trouble. But they always have plenty of fun and lots of laughs. Trunks is usually the boss when he's with Goten. As you have probably guessed Trunks gets his bossy attitude from Bulma. Trunks and Goten can fuse to create Gotenks.
