IDk... like the article said... Goku and Vegeta are the most powerful beings 1000 times over. TO have some other being be stronger than they are and have gone thru what theyve had to go thru to get that powerful would be an insult, stressful and just tiresome.
I like that Toriyama did the "Goku and Vegeta unleash Goten and Trunks on the two aliens, comparing their sons' fighting techniques like parents at a Little League game." thing as well. that kinda shit is always funny and fun to watch.
I just hope the new live action movie does it SOME justice.





thats pretty cool but what if Toriyama brought one more good fight that would have people all over the world shocked the rumor of legendary beyond super saiyan level. and bring in some normal peaceful look a like villain where he just stands in the cementery and says here he will finally lay kakarot to rest in piece as the mightiest heroes once again battle this unknown but this time is not to save the universe, galaxy or worlds for that matter. This time they fight for their very own souls, you fail he will consume it. This is where Goku transforms into that crazy monster look a like thing just an idea. Sort of like the inner demon or something. Super Sayian 7, 8 or 9
