You better rewatch DBZ because it's always greatI've liked the arguments I've read of him being a Ti dom. I would say he is definitely in the Ti-Fe judgement wave length. So some kind of TP, I'm guessing. I haven't watched the series in so long though so hard to nail down his perception functions and the order they are in.
I see Fe in Trunks. Like with his desire to please Vegeta, waiting for Vegeta to faint before becoming an USSJ, since Trunks didn't want Vegeta to lose what drove him to exist: being the best. Even though Cell was a huge threat, Trunks was doing all he could to keep his dad happy.I'm gonna type Future Trunks as an INTP. It's kinda hard he seems like a feeler. He was concerned about his dad liking him. Probably cause he grew up in a dystopia world unlike his present counterpart.
