Fat Boo and Super Boo Differences!

[Hitiro]

I read it as it was the nature of the Dai Kaioshin which subsequently drained Boo's power.

Chapter: 508 (DBZ 314), P4.2-7
Kaioshin: “In m…my era there were five Kaioshins…until they were defeated by the Majin Boo that the wizard Babidi created…I was the youngest and most powerless one, but I somehow survived, with only heavy injuries…But the other four fell to Boo…First, two were killed…the North Kaioshin and the West Kaioshin….And then the South Kaioshin, the burliest and strongest one, was…somehow absorbed by Boo….. “
Elder Kaioshin: …And he became that huge Boo from before? “
Kaioshin: “…Yes…Next to be absorbed was the fat but kind and gentle Dai-Kaioshin….The Majin Boo that Bibidi created was evil itself, a failed creation that even Bibidi himself couldn’t handle, but by absorbing the Dai-Kaioshin, he somehow become controllable…. “
Elder Kaioshin: “…So he was finally completed…Which is to say…that this current…small Majin Boo…is the initial…mo…most troublesome one…”
Kaioshin: “….Yes…the heart which he gained by going so far as to lower his power through absorption…has returned once again to the way it was…he has no self-control whatsoever…he has become evil itself…”

The line I highlighted in a nice orange makes it out to be that only the Dai Kaioshin had any affect on Boo's personality. This is why it makes more sense that the last line in this quote which says "….Yes…the heart which he gained by going so far as to lower his power through absorption…" Is on about a singular aborption. As you can see the Kaioshin mentions "the heart which he gained", well the only time Boo's heart was actually influenced was when he absorbed the Dai Kaioshin. There is no suggestion Boo can't make use of a Kaioshin's ki to become stronger. The only thing we know is a Kaioshin's ki can't be used to release Majin Boo. Nothing is stated that Boo can't use a Kaioshin's ki in any regard other than his own release.

[Pan-Pan]

Even Kibito wasn't scared of "buffbuu."

You make a good point. Kibitoshin is terrified only when Boo returns to his original form. It makes no sense if Buff Boo is even more formidable.

Yes, but in this case, you can't explain why Kaioshin's ki can't be used to release Majin Boo.

Well, we know now that gods have a different kind of ki. Maybe it's just incompatible with the spell Bibidi used to seal Buu?

[Pan-Pan]

Well, this is not really an explanation. Basically, you're just saying "it's incompatible because it's incompatible" without justification or anything on which to rely. I mean, there isn't any hint or confirmation to back up your supposition. So, I can still ask you why it is incompatible.

Why couldn't it be an explanation? We know that Kaioshin energy couldn't be used to revive Buu, while Saiyan and Earthling energy could, and we know that godly ki is different from mortal ki. Seems like a good enough reason to me.
Or maybe they didn't know how Kaioshin energy would react to Buu. All Bibidi knew when he sealed Buu was that one Kaioshin made Buu stronger, while absorbing another one made him weaker. Maybe he told Babidi not to use Kaioshin energy, because he didn't know how it would affect Buu?
Or maybe they didn't want to take Kaioshin's energy because Babidi wanted him to suffer at Buu's hands? Kaioshin was the one who killed Bibidi, after all. It would be much more satisfying to see Kaioshin die at the hands of the monster he was terrified of.

[Kaboom]

SOMETHING about Kaioshin prevents them from using his energy to revive Boo. The recent revelation about true gods having a different kind of ki would certainly fit the bill. It would also explain why Majin Boo absorbing the Kaioshin can seem to have such wild and unpredictable results, compared to simply an addition of power from absorbing anyone else. Well, absorbing HIMSELF also had some weird effects, but the Kaioshin were kind of along for the ride with that one, too.

As a bit of an aside, it's also interesting that Goku HAS been shown to sense and detect North Kaio's ki before, in order to teleport to his planet. Perhaps it's only the special, golden fruit-born Core-people who have the special god-ki and are thus qualified to be Kaioshin.

[Bussani]

Well, this is not really an explanation. Basically, you're just saying "it's incompatible because it's incompatible" without justification or anything on which to rely.

What's wrong with that? I mean, how's the sealing spell being incompatible with Kaioshin ki any different from Buu himself being incompatible with Kaioshin ki? I don't think there are any strong hints either way, personally.

Out of universe conjecture here, and I'm not necessarily saying that this was the case, but I also think it's pretty possible that Toriyama forgot Babidi's line about not being able to use Kaioshin or Kibito's powers to revive Buu. There was quite a gap between those chapters and the first mention of Buu absorbing any Kaioshin, after all.

[rereboy]

Even Kibito wasn't scared of "buffbuu."

You make a good point. Kibitoshin is terrified only when Boo returns to his original form. It makes no sense if Buff Boo is even more formidable.

He's terrified of Kid Buu because he is the same Buu that decimated all of his fellow Kaioshins. I would expect that to leave an impression on him. And, as he immediately explains, this is the most evil and troublesome Buu due to his nature/personality. He never says that he was afraid of him because he was more powerful than the other Buus (and that would be the perfect moment to state that, if it was actually the case. But Instead he merely mentions his nature and personality. I wonder why ).

[Amuro Ray]

Divine "God" energy isn't compatible with Buu - which is why it's the Kai spirit, not his "power" that weakens Buu.

And he also implies, no outright states, that he's more powerful as well. He specifically mentions him becoming weaker at because of the absorption of Dai-Kai.

Fat Buu (more kai influence)
Super Buu (less Kai influence)
Pure Buu (No kai influence)

But it doesn't say anything about him becoming weaker after the absorption of South Kaioshin.

Nothing ever says that god ki is incompatible with Buu, only that it can't be used to revive him. We know that Buff Boo is stronger than Super Buu, an that's the Buu with South Kaioshin absorbed, so obviously he got some power from absorbing him. But Dai Kaioshin's inherent goodness was incompatible with Buu's pure evil. That's why he was weakened.

Which Buu absorbed Dai Kaioshin? That's right, Buff Buu. That means that Buff Buu became weaker by absorbing Dai Kaioshin. Buff Buu is not Kid Buu. Kaioshin never says or implies that Kid Buu became more controllable or weaker when he absorbed South Kaioshin. He only mentions that Buu (as in Buff Buu) became more controllable and weaker when he absorbed Dai Kaioshin.

You are assuming that Buu lost power when he absorbed South Kaioshin, just like when he absorbed Dai Kaioshin, but such is never stated or implied. That is purely your assumption. In fact, given that Kaioshin neglects to state that and chooses to only state that Buu lost power when he took Dai Kaioshin, its seems much more likely that what he is implying is that Buu only lost power when he took Dai Kaioshin and not before, meaning that South Kaioshin didn't affect him in a negative way.

[TheMightyOzaru]

I'm pretty sure there is a guide book that states Southern Kaioshin increased Pure Buu's power. Let me go see if I can find it.

ALL forms of Buu became weaker from the absorption of Dai Kaioshinn, there is nothing stated anywhere to imply otherwise. Actually, the statement about Buu being weakened and Changed was referenced twice. Once by SuperBuu when Vegeta threatened the removal of the FatBuu ("I'll cease to exist"), and again when Buu is transforming, Kibito talks about how Buu (who at this point is still Superbuu) was weakend by Dai-Kaio. No matter what, all Forms of Buu were effected by his presence.

Again, why would Buu absorb Dai Kaioshinn if the previous Kaio was noteably stronger and "buffed" his power?

Why wouldn't he? Even if Dai Kaioshin was weaker than South Kaioshin, it would still give a power increase.

Then why would he not just absorb all of the Kai's or everyone?

[Bussani]

If Buu put that much thought into it, I'd wonder why he'd try absorbing another Kaioshin if the last one only made him weaker. Kind of a dumb move.

[Kamiccolo9]

Because the only people we know he fought were the Kaioshins. He killed the first 2, and absorbed the 3rd. After absorbing the South Kaioshin, he absorbed Dai Kaioshin, he and became Fat Buu. Fat Buu was way more manageable than Pure or Buff Buu, and only did what Bibidi told him, which must not have included absorbing people.

But why absorb the last Kai at all?

Do you mean the South Kaioshin, or Dai Kaioshin?
If you mean the South Kaioshin, then it could be because unlike the others, he was able to put up a fight. I know it's filler, but the anime supports this, and there's nothing to contradict it.
If you meant Dai Kaioshin, then I think this has been answered numerous times already. If the last Kaioshin he absorbed made him stronger, then Buu has every reason to assume that this one would as well.
