The one thing about Trunks' character that I always loved was he was by far the most serious when it came to fighting. I mean that in the sense that both Vegeta and Goku fight for the sport of it. Gohan doesn't like to fight either but he never had a fighters spirit and people died waiting for him to build himself up to do something. I respected Trunks because he doesn't fight for the sport of it like Goku/Vegeta but he recognizes the need for brutality and will not hesitate to do so. He won't play around for honor (saiyans), or out of fear or compassion (gohan). My nikka will jump out there and interrupt a fight if he feels the need to. He won't watch some shyt go down.
