Is it up to fans to headcanon how Goku and Vegeta can regain all their stamina in 20 seconds?

[Lord Beerus]

If Goku needed one minute to regain his full strength as a SSJ3, then it's not out of the realm of possibility that with the better training Goku and Vegeta have being under the tutelage of Whis, with the extensive teaching of Ki control, that they can recover their energy just as fast as when they lose it.

Also... this is Dragon Ball. A story that prides itself on occasionally using nonsense to move the plot forward.

I hate this excuse. Just because they did it in the past, it doesnt make it okay to do it now.

I'm not saying it's acceptable. Just saying that it happens, and you shouldn't be shocked at it happening again.

It was established by Toriyama in the movie interviews that Saiyans get stronger as the fight goes on. Can even surpass their enemies in the middle of battle. TOEI just continues that.

It wasn't Toriyama that said that in an interview, Vegeta outright states this during the Freeza arc in the manga.

True. But Vegeta was referring to Zenkai''s; recovery from near death?
Toriyama stated they grow while fighting and this has been demonstrated by Goku in BOG. Even Vegeta's rage power up against Beerus. They didn't have near death experience...I think Goku did tho.

It's quite simple, Dragon Ball runs on bad Shonen tropes now like Fairy Tail where determination and loving yur nakama allows you to fight in perpetuity, even if the series (on many occasions) says you're totally drained.

You know, that thing Dragon Ball never did even at it's dumbest of moments before. But then again, this is the show where Krillin could do this to 100% Cell:

Thanks to "strategic and tactical" looping of punches and kicks which is TOTES different from the brawling kind of looped punches and kicks:

The Frieza fight hinged on this very thing. Goku used the Spirit Bomb on Frieza out of desperation because he overtaxed himself with Kaioken and was rapidly losing what strength he had left, but then he gets pissed off over Frieza killing his best buddy and oops he's fully recovered his stamina and energy.

Which never happens to him again and also occurs after his determined KK and Spirit Bomb both spectacularly fail despite his sheer, absolute, determination and need for them to work, they don't. It's more of an exception and not the rule. He was super determined to beat the Androids and that didn't glitch out his heart virus, nor did it make him any more capable of beating Cell. It didn't make him capable of beating Kid Boo,...

To use other people as an example, Gohan got super determined many, many times and it never bloody works. He gets pissed at Raditz and dents his suit, Nappa bitch slaps his desire to avenge Piccolo (literally), Freeza shrugs off both attacks of similar nature and he doesn't even beat Cell with this since he needed Goku and Vegeta to help him to win. If Super wrote the beam clash between Gohan and Cell, Gohan would've healed his fucking arm in seconds because he's super determined to win.

Vegeta is also constantly super determined and it never works. He tries everything to kill everyone in the Saiyan arc and he gets smashed for it. Freeza breaks his spirit despite how profoundly he wants and needs to win, Cell just trolls him like a moron both times he gets mad and determined and Kid Boo just regenerates from his big sacrificial moment.

So yeah, out of ALL these instances, the one time Dragon Ball did it when it could be called halfway good does not prove anything except that exceptions exists. If anything, Dragon Ball went out of its way to show just how pointless determination and not backed up by something else is that it makes me wonder why the fuck everyone clearly apping it afterward decided to do the exact opposite.

This is the writers' decision to include an enemy dozens of times more powerful than the main cast and denying them the time to train and match his strength coming back to bite them.
