Trunks didn’t get a lot of good time in Dragon Ball Super, but he had a decent role in the sequel series.
He does spend too much time in the series just goofing off with Goten.
I did think it was cute that he had a crush on Mai.
He does become Gotenks when they fuse against Lord Beerus and Frieza.
Which he failed most of the time.
I did think it was funny, that he had no idea that Future Trunks existed. How Vegeta or Bulma didn’t tell him before is a mystery to me.
