Why couldn't' Goku stop kid Buu's attack?

[AvatarReiko]

So I just did a re-read of the manga and I am at the bit where Kid But blows up the earth. There is one thing about this scene that I don't quite understand. At at this point in the manga, Goku was par with Buu in terms of KI with SSJ3. Just as Buu releases his attack, Goku says something along the lines of "It's too big. We can't stop that". This doesn't make sense. Could he have jumped to SSJ3 and deflected Buu's attack with a full power Kamehameha? It's already been shown that Goku can turn SSJ3 instantly. I was hoping someone could clear this up for me.

Perhaps he didn't have the needed stamina to do both a transformation and a full-power kamehameha? Goku didn't surpass Super Saiyan level after defusing until Kaioshin took him to Supreme Kai's world, after all.

Doesn't it take a bit of time to not only go SSJ 3 but charge a really large Kamehameha? And Kid buu had already gathered a lot of energy for that attack.

It's probably just an issue of time.

[ChiefWamsutta]

He was thinking about how to save the ones he loved because he could not gather enough energy in time.

Then he had to switch focus to Dende, and then try and concentrate on the World of the Kais.

He had a lot to worry about in such a short time span. He definitely could have.

Goku instantaneously turned SSJ3 against Majin Boo Gotenks Absorbed.

You're right indeed. He even does so against Kid Buu.

Yeah in the manga at least. The anime he fought as SSJ2 first, then went full power afterwards.

Goku probably was just thinking about Piccolo and their sons's immediate safety before taking action against an unhinged foe that has no qualm launching planet busters around without any regard for itself or anything else, Goku does later block a massive uncharged Ki blast by Kid Boo during their fight in the Kaioshin realm and it takes several seconds to hold that back. He may of not desired to risk their chances of survival on any" would've" or "could've" in the heat of the moment.

I just chalk it up to "Rule Of Drama". Toriyama needed to raise the stakes as high as possible for what seemed like the final battle in the story.

[Tectorman]

Maybe it was supposed to be more the nature of the energy blast rather than the power of it. Energy blasts have "hard" or "soft" surfaces depending on how they're formed and fired. Some act like they're washing over an opponent with no real surface to interact with, while others can be physically blocked and diverted. So Goku may have recognized that Kid Buu's blast was the sort that would continue on without limit, completely independent of his attempts to fire blasts at it (which would just go through) or block it by himself (and it would just continue past him).
