It makes sense since they really don’t have ties with Gohan like they do to Goku and Vegeta. They should have thrown Trunks and Goten in the movie too so they can get some sort of relevancy.
Vegeta’s explosion against Buu
Goku vs Vegeta beam struggle
Gohan vs Cell
Freeza blowing up Planet Vegeta (I know the Bardock special isn’t cannon but I like it)
Goku’s feet KMHMH
I think he was just testing to see if he was really strong enough to absorb Gohan or not, but I haven’t watched the anime in forever so I don’t really remember much. Or it was just additional fighting to stretch out the episode,
I tried to get into Gintama but couldn’t stopped after 20 episodes or so. Heard it gets really good after a certain point but I didn’t make it that far. Might try reading the manga someday.
The only time I think Krillin as over Ten was after the potential unlock until he died on Namek. Ten ended up doing extra training on King Kai’s planet until he got revived since he insisted to wait until he can return with the midget mime.
