What if Goku didn't join the 25th Tenkaichi Budokai?

[dbzfan7]

Or in other words, what if Goku didn't come back to earth on that day. I think Vegeta and Gohan, but mainly Vegeta would have put a stop to Boo before he was brought back.

[Kid Buu]

Vegeta kills Dabura.

[dbzfan7]

Vegeta kills Dabura.

I think Vegeta may just end up fighting all of them.

[dbgtFO]

Yes a Battle Royale(incidentally it's first now I realize why that game is called Zenkai Battle Royale) with Vegeta vs. anyone who stands in his way.
Vegeta would win of course without taking any damage to boot and Majin Buu wouldn't even be revived.
...
Or maybe he would, Vegeta might crave a proper challenge now, that he can't fight Goku and Gohan is pathetic. So maybe, but yeah otherwise Vegeta just kills them all.

[Super Vegetto]

Gohan/Vegeta/Kaioshin enter the ship. Kill Pui Pui and Yakkon. Vegeta kills Dabura or Gohan transforms in SSJ2 and kills Dabura. Babidi is also killed and Majin Boo is sealed for eternity.

[Hellspawn28]

Goku was the reason why Vegeta became Majin Vegeta. Without Goku, Buu would never be hatched. I think AT would have Piccolo fight Yakon instead having him be turn into stone. In BOG, they would be screw by Beerus.

I wouldn't be to sure. It was Boo who pissed off Beerus, if Boo isn't there to annoy him, then he may have left peacefully.

If we keep this purely in-universe, then only Gohan and Vegeta would have entered (since Piccolo was deemed too weak).
I doubt that Vegeta would have let Gohan fight. Even so, Vegeta would probably have fought Dabra himself.
Gohan would have gotten his energy sucked out, as there is no reason for the fight to go the same way.

The fights would be (if they used the Janken and Vegeta respected that it was Gohan's turn):

a)

- Puipui - Vegeta (Insta-kill)
- Yakon - Gohan (as with Goku, he would probably use SSJ2 or something similar)
- Dabra - Vegeta (Dabra is easily defeated)

or

b)

- Puipui - Gohan (Insta-defeat)
- Yakon - Vegeta (as with Goku, he would probably use SSJ2 or something similar)
- Dabra - Gohan (The same as in the original storyline)

In both options Buu is never hatched, Babidi is killed by Vegeta (before he releases Buu) or Buu is released with half-power (and is subsequently defeated by Vegeta and Gohan). Peace on Earth.

Another scenario could be that Vegeta is taken over by Babidi against his will. In this case, either he fights Gohan and fills the meter up, the story proceeds as usual. Buu survives Vegeta's sacrifice, Trunks is intercepted by Babidi and Buu and is killed (no Goku to stall him). Buu kills Babidi and befriends Mr. Satan. Fat Buu becomes Super Buu. Gohan trains in the Kaioshin realm.
Now we have several outcomes:
a) Vegeta returns on his one day, and fights Super Buu, but is beaten badly. Ultimate Gohan arrives and fights Super Buu. Super Buu absorbes Vegeta, but still hasn't got the advantage and loses.
b) Vegeta returns on his one day, and fights Super Buu, but is still beaten badly. Ultimate Gohan arrives and fights Super Buu. Super Buu absorbes Gohan. Everyone dies.

In any of the options, Goku could arrive on his one day anytime, so in that case, we have Vegetto and they will eventually prevail in their fight (although it's not as much fun that way).

Kaioshin stated that half-power Buu would still slaughter them all, which would match with how powerful fatso was portrayed to be later. Everyone dies here if they go with Vegeta's plan.

No Vegetto. Super Buu would have already killed or more likely absorbed Vegeta.

You're also not considering the more likely outcome in that case: with no Gotenks to stall him, Buu just blows up the Earth and goes on to continue his reign of terror across the universe with no one who can even think about contesting him.

[Hellspawn28]

Buu hatch because of Goku and Vegeta. Without Goku, Vegeta would never go Majin and everyone would have a happy life afterwards. Maybe Beerus would not destroy the Earth unless someone pisses him off. If you want to throw in GT then Bebi would take over the Earth since no one would be strong enough to stop him.

[Godo]

Kaioshin stated that half-power Buu would still slaughter them all, which would match with how powerful fatso was portrayed to be later. Everyone dies here if they go with Vegeta's plan.

Good point, missed that. One could argue that he was using half his power initially against Majn Vegeta as well, until he got mad in the fight.

No Vegetto. Super Buu would have already killed or more likely absorbed Vegeta.

Vegeta getting killed at pretty much any time is given, yes.
And also, when I reconsider this, for Vegetto to exist, Goku has to reach the Kaioshin realm, and this means that he would have to know that Gohan is there, even if he is in the afterlife.
So there is a high likelihood that Goku won't make it in time.

You're also not considering the more likely outcome in that case: with no Gotenks to stall him, Buu just blows up the Earth and goes on to continue his reign of terror across the universe with no one who can even think about contesting him.

Quite true.

[Marco Polo]

Vegeta is the guy that let Cell reach his perfect form. I wouldn't be so sure that he would prevent Buu's release.

I agree.

In my head it plays out a little bit like this:

//Fanfic

Spoiler:

Vegeta would probably refuse to go with the Supreme Kai at first, and insist on fighting Gohan at the tournament. Upon realising that Gohan was going to go with Kibito, Vegeta would have followed him to the ship, gotten frustrated with the lack of leadership shown by Gohan and taken control of the situation. He'd have probably killed Pui Pui and then, without anyone to restrain him, chose to blast his way through the rest of the ship, forcing Dabura into combat before he could gather his power through meditation.

Contrary to what some people think, I believe the fight with Dabura would have been much more of a challenge for Vegeta than most seem to agree - as I take Goku's comment that they initially underestimated his power as being a fair representation. Whether Vegeta would have been able to kill Dabura by the time Majin Buu was released or not is debatable, but I don't think so - as I think Vegeta would either be unable to land a quick victory or, seeking a greater challenge, intentionally allow Dabura to elongate the battle to facilitate Buu's release.

At the point of Buu being released, I imagine that both Dabura and Vegeta would be killed - possibly Gohan too, or possibly not, depending on if the Supreme Kai was able to take him to the world of the Kais.
