You're going to have to explain the difference between Present Trunks and Future Trunks to me because I don't know anything about Dragon Ball.
Future Trunks, molded by the tragedy of his time, is a well-mannered and courageous teen who ends up getting tired of the fact that the others didn't heed his warning of the Androids seriously enough. His attire, with the iconic jacket, would be his defining look in Z. During his first appearance, Present Trunks wasn't even born, while during his second, he was, but was still a baby. In Super, now a grown adult, he'd switch for a different look.
Present Trunks, deliberately on contrast, is framed as a cocky dick of a kid, raised during a time of peace and calm. Though the seriousness of Z's final arc would help him get better, his cockiness is something ingrained. His attire in Z, with his dougi, sets him further apart from his Future self. He'd often be paired with Goten, and would lead to Gotenks later on. He keeps the same look in Super, most likely due to marketing reasons. The brief End of Z would finally see him aged up to the same age as Future Trunks, but the attitude difference remains, and it would be this Trunks that would join Goku and Pan in the non-canon GT.
Neither share many techniques, owing to their different teachers, their attitudes and interests are distinct due to the different worlds they grew up in, and when folks think of Trunks in Z, it is typically Future Trunks, as a result of him being a more interesting character to folks.
