I'm not saying that old obstacles do not work in practice. It's more to do with the somewhat arbitrary nature of their introduction. Freeza ruling most of the galaxy and being the strongest adversary the universe has ever known would be fine... if we didn't know later find out that Majin Boo had exist much earlier than he did and was running amok through out the universe for God knows how long. Cell is fine in a biologically technique, but his origins are absurd if you think about them for more than 60 seconds. You've already pointed out how much of an issue #16, #17 and #18 are, so I have nothing to add to that.ekrolo2 wrote:I think a fair amount of the old obstacles do work, not all but a fair amount do. Freeza being this classic galactic emperor of incredible power makes sense for the guy who's essentially Vegeta's boss, 19 and 20 have the energy absorption to boost them into higher echelons of strength, Cell is a monster composed of everyone's disparate elements, Majin Boo is the classical ancient evil unleashed on an unsuspecting galaxy. Really, it's 17, 18 and 16 who really stick out for having no good, even story convention reason to function as villains.Lord Beerus wrote:This is has been a long running issue in Dragon Ball.
Goku and Vegeta go to hell and back to become stronger after the Saiyan arc, and Freeza just waltzes in and makes their effort nearly meaningless, if not for the Saiyans getting that contrived "beaten up very badly" power up. Then when Goku and Vegeta become uber strong after Namek, along come #16, #17 and #18 to undo all that work, forcing them to reinvent the SSJ wheel. And when they do, Cell arrives and sets them back again. And when they overcome that obstacle, Majin Boo arrives. And they exhaust every gimmick technique or power-up to keep up with him. And then when they get through with him, Beerus becomes a thing. And then after training with Whis, who by all accounts is the greatest martial artist teacher Dragon Ball has ever had, for several months, Golden Freeza pops out of nowhere and rivals Goku and Vegeta's new founded power under the tutelage of Whis. Then cue the other universes...
I guess what I am trying to say is... bigger obstacles will always be a thing for Goku and Vegeta to overcome, regards of how much work they put in to reach new realms of strength or how contrived the nature of the obstacle the have to face is.
It may seem a bit depressing that for all of Goku and Vegeta's, a randomly plucked Saiyan from another universe can match them in strength in their base forms, but it is what it is.
Besides, there were no guarantees that other universe would have to abides the power hierarchy that Universe 7 had set
Beerus feels wrong to exist in a world where Majin Boo already periodically destroys worlds then goes into hibernation, Golden Freeza is a big load of bullshit, Cabba is a rookie Saiyan who can stomp basically everyone from Z in his Base form no problem, Hit apparently never trained a day in his life if his basic use of Time Skip is any indication yet he's somehow Blue tier, Future Trunks, Piccolo, Gohan, 17 can masturbate off screen for a few days or years and catch up Goku and Vegeta with not even a tenth of the effective training methods available to them,...
And as far as off-screen training goes, we are way past the point of raising an issue with that. Piccolo went from weaker than Third Form Freeza to being arguably as a strong as SSJ Vegeta and Goku by doing... something... for three years. And in an alternate timeline, Trunks and Gohan were able to jerk themselves for an unspecified amount of time and become SSJ's. (And kind in mind, in the manga version of events, Future Trunks was already a SSJ by the time Future Gohan bit the dust.)
