What I liked most about trunks debut was his sword! He chopped freiza and his minions into nothing but that's the last time we saw that sword do work. He broke it on 18s arm! Then he kinda just stopped using it.
I thought it was pretty legit trunks finally got a hit in with it. I thought he was about chuck it because it was useless but nah.
Who would ever throw away a trusty sword?
(I'm looking at you sokka...throw away a cool space sword...the hell)
