Yeah,I kinda ignored Tenshinhan's feats during the later arcs.
Krillin was still way more useful during the Saiyan debacle.His Kienzan would have actually killed Nappa if not Vegeta's warning,for one thing,and he was part of the team that actually defeated Vegeta(that whole "weaklings save the day" was very neat btw.Kishi could learn a thing or 2 from that particular fight).He also had a very active role on Namek.
So yeah,it's a toss up.Also,Yajirobe.He intervened nicely not once but twice.Plus his feats were actually meaningful in the long run and he didn't die in the process.
So yeah,3 humans that actually did something in the story that's known for having Yamcha often making the supporting cast seem useless.4 if we realize just how much Bulma's creations drove the storyā¦
...man are the Kages undewhelming right now.
Also,Sasuke is weird.He is going to do terrible things for his brother,eventhough his brother flat out tells him that he doesn't want this.Can't he just say that he is looking to avenge the clan and not his brother?Atleat it'll make some sense.
