Buu Saga Info

[Super Saiyan Turlast x4]

Let's look at it from a simple standpoint:

When they're within Boo, Goku mentions that they'll need to return Boo back to his normal form to have a chance. Goku and Vegeta come across the absorbed Gohan, Goten, Trunks and Piccolo, which gives them the opportunity to weaken Boo. Goku comments on how much weaker Boo had gotten, noting that his Chi was "a lot smaller" afterwards.

So, Goku did what he thought they needed to do to have a better a chance against Boo; it's right there in the Manga. Goku had a plan to return Boo to his normal form and this plan went well. However, even after noting how much weaker Boo had gotten, he mentions that Super Boo's still more powerful than both of them. What does this mean? Super Boo wasn't weak enough to challenge. Goku's overall plan was a success--he just wasn't expecting Super Boo to still have a power advantage, which he did even after the absorptions were gone.

There's absolutely no logical reason why he'd lie at that point. Unless Goku had a sick fantasy of wanting to join with Vegeta, Goku tells us they can't beat Super Boo seperately. It's stated.

I know many others have reiterated this millions of times, but read my post and try to look at it from a different light.

Could you reply to my above post?

Using ONLY the story - and information provided within it - tell me how this information is incorrect. If you "make up" theories or powerlevels, I'll just ignore the whole statement and consider this arguement forfeited on your part.

One Kai actually lowers his power when everyone else boost it, Kai's power can't be used to revive him and no mention of a supposed "HUGE" boost in power from south Kaio. These are true, unless you can prove otherwise.

Kaio Power was said to not be compatible with Manjin buu’s revival. Nothing states that South Kaio was removed from buu – nothing states that South Kaio boosted Buu – Kibito makes mention of Buu’s power boost AFTER Goku comments about the “being able to handle it”

But hey, it's just easier to make up things as we go along right?

Lol hey guess who just ignored more evidence and a hardcore fact outright stated in the manga after pulling a hissy fit and saying there needs to be a stop to fan theories? Goku states Super Buu >> Goku + Vegeta. Fact, supported by the manga, the official source of information. There is no way around this except with your fan theory that Goku was lying, but fan theories don't work anymore right?

Stated fact: Goku and Vegeta are no match for Evil Buu

Chapter: 506 (DBZ 312), P12.4-5
Context: after Goku and Vegeta revert Boo back to regular evil Boo
Goku: “Hehhe~~eh! With this, Boo’s power should have fallen significantly! We’re almost there! See, see: the size of his ki is completely different than before!”
Vegeta: “Alright! Let’s blast out of here and escape!”
Goku: “Wait! Even though Boo has returned to normal a whole lot, we’re still simply no match for his strength! If we go outside like this, we’ll definitely be done in…!”

Stated fact: South Kaioushin Buu's power is above Evil Buu's power

Chapter: 507 (DBZ 313), P13.5
Context: as evil Boo reverts to his South Kaioshin form
Goku: “H-hey…Vegeta…His ki is increasing, ain’t it…!?”

Stated fact: Goku thought he could handle Pure Buu

Chapter: 508 (DBZ 314), P3.4-6
Context: after Boo reverts to his pure form
Goku: “…”
Vegeta: “……Heh…Heheheh…Look! He’s shrunk down quite a bit!”
Goku: “We did it! This way, we might be able to manage something.”

Chapter: 510 (DBZ 316), P13.1-6
Vegeta: “Don’t hesitate for my sake, and finish him off! With that Super Saiyan 3, you should be able to completely wipe out Boo with your ki once you gather it with all your might…!”
Goku: “Ye…yeah…I’ve been thinking of doing that as well since awhile back, but…I haven’t gotten the chance.”
Vegeta: “Eh?”
Goku: “If I want to wipe him out, I gotta gather ki for about one minute.”
Vegeta: “One minute?!”
Goku: “Dammnit~~~If it was with the Potara, I could have done it in one blast. …..Cheh~~~I guess I went and showed off too much. But I thought things would go a little better than this…!”
Vegeta: “…S …So you weren’t thinking of me…”

Since there's nothing at any point in the manga saying or suggesting that Goku was lying when he told Vegeta about their odds against Evil Buu, we get this.

Evil Buu > Ssj3 Goku and Ssj2 Vegeta
South Kaioushin Buu > Evil Buu
Ssj3 Goku > Pure Buu
South Kaioushin Buu >> Ssj3 Goku
South Kaioushin Buu >>> Pure Buu

[Amuro Ray]

Ok, but how does that counter that South Kaioshinn buu and KidBuu have the same power? Since KibitoKai said comments on his increased power AFTER the transformation? Where does it state South Kaio increased power, or that he (or this claimed power) was removed when Buu became Kiddbuu?

[Darkprince410]

It's in Goku's comments. He felt that he and Vegeta wouldn't stand a chance against Evil Buu, then Evil Buu reverted into South Kaioushin Buu and powered up. That'd make South Kaioushin Buu even more impossible for Goku and Vegeta to fight. Then South Kaioushin Buu reverted to Pure Buu, and Goku was suddenly more confident in his abilities to win. He was so adamant against the idea of fighting Evil Buu that he didn't want to leave until either A) He and Vegeta agreed to fuse, or B) They weakened him more.

As for Kibitokai's comment on a power increase, I don't know which comment you're meaning.

If it's this comment:

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…”

Then the last line is simple. He's just saying that he gained a heart and lost power as a result of it. However, it's not losing power from Pure Buu, but from South Kaioushin Buu, which is (as shown by my previous statement) to be far above Pure Buu in power. The entire dialogue between Rou Kaioushin and Kibitokai is establishing that Pure Buu fought and killed North and West Kaioushin, absorbed South Kaioushin and became South Kaioushin Buu, then grew a heart after absorbing Dai Kaioushin, weakening Buu's overall power from his previous form (S.K. Buu) and resulting in Fat Buu.

[Amuro Ray]

Uh huh...so about S.Kaio adding power is stated where?
And you quote makes it seem as if Kiddbuu is stronger than "buffbuu"

Shown to you over and over and over again. Just accept it, this is a very plausible alternate viewpoint from yours.

[Darkprince410]

Okay, we have Evil Buu and where Goku believes his battle power is (stronger than Goku and Vegeta could fight against)

Evil Buu reverts to South Kaioushin Buu, which is the form of Buu with just South Kaioushin's influence on it (that is where the "ki getting bigger" statement comes from)

Then South Kaioushin Buu reverts to Pure Buu, which Goku says he can handle in a fight.

South Kaioushin Buu is therefore stronger than Evil Buu, who is in turn stronger than Pure Buu

The drop in power from South Kaioushin Buu to Pure Buu is the exact opposite of when Pure Buu absorbed South Kaioushin (it's like Buu absorbing Gohan, then Gohan being removed from Buu)

[Amuro Ray]

Once more, where is it indicated that Buff Buu is more powerful than Kidbuu. You're quoting a conversation that occurred while buu was transforming into KidBuu, or do we need to post the panels to help you uunderstand?

You both are well aware what I'm pointing out, don't make me have to do it myself.

No, we're not aware of what you're pointing out, because the dialogue between Rou Kaioushin and Kibitokai doesn't say anything about his power still increasing. The whole conversation between the two of them is just talking about Buu's past in total. I already explained the whole situation with it in my earlier post. He explains that Buu fought and killed West and North Kaioushin, then absorbed South Kaioushin, which resulted in the "buff" Kaioushin Buu we see. He then absorbs the kind Dai Kaioushin and gains a gentler heart, losing power in the process. Now, as he's reverting back to Pure Buu, his pure evil heart is returning, no longer affected by Dai Kaioushin's good heart.

I also explained where it's indicated that Kaioushin Buu is stronger than Pure Buu. Goku says that Evil Buu is too strong for him and Vegeta to fight. Then, as Evil Buu reverts to Kaioushin Buu, Goku comments that his ki is rising rather than falling. This indicates then that Kaioushin Buu is stronger than Evil Buu. Goku later says on more than one occasion that he'd be able to defeat Pure Buu on his own. This puts Pure Buu below Goku, who is below Evil Buu, who is in turn below Kaioushin Buu.

Evil Buu > Ssj3 Goku
Kaioushin Buu > Evil Buu
Ssj3 Goku > Pure Buu

Thus

Kaioushin Buu > Evil Buu > Ssj3 Goku > Pure Buu

[Undertaker]

Vegetto is the result of a Kaioshin Item so it's the reason why his power was the same since Buu and the gods are incompatible but yes, Super Buu >>>>>>>> Goku

Buu and the gods ARE compatible, otherwise Southy wouldn't have boosted Buu to the level that he did.

Well, Dabura says they can use Kaioshin's ki to revive Buu. Vegetto defusing inside Buu's body.

[TheMightyOzaru]

Not the case at all. It's very possible that Buu's evil energy can reverse the negative effects a Kaioshin would have on him thus giving him power.

[BejitaSama]

I'm sorry guys, but I understand now why we disagree : I can't assume that Super Buu is ten times stronger than the Fat, there is no way for me. It's an incredible gap, and I think other characters would have noticed it, by another statment that "better body, greater skills and pure evil".

Here my interpretations of the Buu saga. All the battle powers are justified. Let's go !

Majin Buu [Full Power]: 25,000 K
[At his full power, when he gets very very angry]

Majin Bejita : 12,000 K
[When Majin Buu gets angry and show his true power, Bejita is no match for him]

Gokû SSJ3 [first appearance] : 21,000 K
[He makes a toe-to-toe battle with the Majin]

Pure Evil Buu : 15,000 K
Good Buu : 10,000 K
[It says both in the manga and in the anime that Pure Evil Buu took most of the power of Fat Majin Buu].

Super Evil Buu : 37,500 K
[Not an enormous gap between him and Majin Buu Full Power because of Piccolo’s statements : “his body has changed, more suitable to fight” “he’s pure evil”, “all in him is greater”]

Gotenks [Post-ROSAT] : 9,750 K
Gotenks SSJ1 [Post-ROSAT] : 19,500 K
Gotenks SSJ3 : 39,000 K
[Gotenks SSJ3 is a little be superior to Super Evil Buu, but the monster was planning since a long time to absorb him in order to beat Gohan, so…The gap is, I think, not so big.
To deduce the strength of Gotenks SSJ1 and base, if we apply the super saiyajin multipliers, we have to divided 39,000 by 4 to have Gotenks SSJ2, which would put him at 9,750, which is too low I think…So there’s a problem between multipliers gave fifteen years later and Gotenks progression in the manga…or, Gotenks SSJ1 is weak.
It’s sure that when Toriyama wrote the manga, he didn’t thought about this kind of multipliers so…I try my explanation, which is that Fusion has specific multipliers : SSJ1 = Base x2 ; SSJ2 = Base x 3 ; SSJ3 = Base x 4. During his fight against Super Buu, when he went SSJ, he was also no match for Super Buu, so I didn't think that Gotenks multplied its power by 50 between his base an SSJ.]

Ultimate Gohan : 50,000 K

Super Evil Buu [Gotenks absorbed] : 76,500 K
Super Evil Buu [Gohan absorbed] : 87,500 K
Super Bejito : 150,000 K

Buff Buu : 42,500 K
[Buff Buu is stated to be more powerful than Super Evil Buu]
Kid Buu : 50,000 K
[He’s the original Buu, stronger than Fat Buu because of the absence of Kaioshin(s). He's pure evil, wihtout any restriction of Kaioshins.

How I see Buu's transformations :



Super Buu has a different apperearence and is stronger than Fat Buu because his evil side is dominant. But he keeps a part of the Kaioshin influence : he didn't kill Satan twice, and likes chocolate, candy...as Fat Buu. To complete this explication :

We know that Super Buu used a special treatment for Good Buu. We also know that without Good Buu, he reverted into Kid Buu and that he was scared when Bejita wanted to cut the cocoon : "No ! Don't ! I won't be my self anymore !".
I think it's pretty clear that the special treatment is that Super Buu voluntary restricted himself, because he knew that without Good Buu, he would become Kid Buu. So the cocoon of Good Buu is not here to drain its power as it do for Gohan and the boys, but to maintain a link with Good Buu influence, which permit him to keep his personnality (don't forget that Super Buu IS Fat Buu with the evil side dominant).

Gokû SSJ3 [Full Power to fight against Kid Buu] : 48,000 K

[Mjb1985]

Base Gotenks Post > Ssj Gotenks Pre > Ssj3 Goku > Base Gotenks Pre > Ssj2 Goku

Is by far the hardest chain to swallow in the manga. You run into conflicting official numbers. On one hand Super Saiyan is 50x. Yet Ssj3 is only 4x.

Super Saiyan Gotenks 100
Ssj3 Goku 4
Base Gotenks 2
Ssj2 Goku 1

That is just really unfortunate. Then Base Gotenks is even superior making him what 150 or so? Jesus.
So sticking with official boosts won't get you anywhere with that chain. And then altering boosts is a problem as well.

Just one big headache all around for these Gotenks quotes. No wonder everyone quickly dismisses them.

[Hitiro]

Then BejitaSama, answer me this.. If Pure Boo is more powerful than Buff Boo and Evil Boo(Super Boo) why does Goku say they would be destroyed by Evil Boo but when Boo finally becomes Pure Boo; Goku is relieved and thinks he can take Pure Boo?

Chapter: 506 (DBZ 312), P12.4-5
Context: after Goku and Vegeta revert Boo back to regular evil Boo
Goku: “Hehhe~~eh! With this, Boo’s power should have fallen significantly! We’re almost there! See, see: the size of his ki is completely different than before!”

Goku: “Wait! Even though Boo has returned to normal a whole lot, we’re still simply no match for his strength! If we go outside like this, we’ll definitely be done in…!”

^This quote Goku explicitly says they can't beat Evil Boo.

Chapter: 508 (DBZ 314), P3.4-6
Context: after Boo reverts to his pure form
Goku: “…”
Vegeta: “……Heh…Heheheh…Look! He’s shrunk down quite a bit!”
Goku: “We did it! This way, we might be able to manage something.”
Note: "He’s shrunk" is chidzimu, which typically refers to physical shrinking (like with Bulma's Micro Band) and throughout DB is never used to refer to ki diminishing. So Vegeta's probably talking about how Boo’s body has shrunk. That doesn't mean Boo's ki didn't go down too, but it's not what Vegeta's talking about here.

^In this quote when Buff Boo turns into Pure Boo, Goku says "We did it!" Did what exactly? What we know is Goku was trying to weaken Boo so obviously they succeeded.

[Mjb1985]

Fusion having specific multipliers seems like a good route. But then to apply it to Vegetto sucks then too. Meh...

Perfectly right ! And it's the same problem with SSJ Gotenks.

Of course Hitiro !

For the first point :

- This is the statement that contradict my theory. So I have to make a big supposition : I personnally think two things :
--> At this point of the story, Goku is stated to be not sure to beat Fat Buu. So at this level, he can't be Super Buu. But I think that later, against Kid Buu, Toriyama had to make Goku stronger so this is at this moment that he chose the real level of Goku SSJ3. The same as Kid Buu, which is for me (excluded this statment of Goku) clearly presented as the strongest Buu without absorption.
--> The statments on Goku's strength by Goku himself are never clear. Why did he lied to Piccolo when the Namek asked him if he could beat Buu ?
We don't really know. So, I would say that here too, Goku lied.

For the second point :

You are totally interpreting the sentence ! They never talked about his Ki ; Bejita is mocking Kid Buu's size, and Goku (who is totally stupid) respond. They make a big mistake by judging him by his size. Besides, when Kid Buu cries (and show a part of his Ki), they're not so confident. And this only when they faught Kid Buu that they realized their mistake. Goku said something like : "he's better than I thaught" and Bejita "How can Goku did a match against him ?? This Buu is terrible !"

And I return you the question : How can Super Buu be stronger than Kid Buu knowing that he's still under the influence of the Kaioshins, an evil version of Fat Buu ? (If it's something with the South Kaioshin...we see him only in one image of the manga, it's never suggested that he could be a source of power for Buu, so it's clearly an out-ouf universe argument...possible, but maybe more far off the manga than my argument against the Goku<Super Buu)

Fusion having specific multipliers seems like a good route. But then to apply it to Vegetto sucks then too. Meh...

With my fusion multipliers, it's good too for Bejito
I put Goku and Bejita SSJ at 6,000.
Gotenks SSJ at 19,000.
Goten and Trunks around 1,000. So Gotenks is 19x more powerful than they boys individualy.
Goku and Bejita SSJ x 19 = 114,000, you add the boost of the potara and the rival thing, and you're at 150,000

[Mjb1985]

I like messing around with the boosts. The best you are going to get is using roughly the same boost for Ssj and you do for Ssj3. So a strict 50x guy gets himself into some serious trouble here. But even with 50x is it so bad? Power levels got to insane , unfathomable levels. Wouldn't figuring out the numbers and being disgusting by them basically put you on the right track? I'm sure a 50x Ssj3 boost would aid in the effort making Vegeta x Goku work.

I just disagree with the , the numbers are too high this can't be right logic.

[Hitiro]

For the first point :

- This is the statement that contradict my theory. So I have to make a big supposition : I personnally think two things :

We don't really know. So, I would say that here too, Goku lied.

So you are saying that Akira Toriyama was making Majin Boo go under another transformation and rather than make Majin Boo weaker Akira Toriyama thought "I know! I'll make both Majin Boo and Goku stronger!" wouldn't it make more logical sense to just change the character who's undergoing a transformation rather than change a character who's undergoing a transformation and change a character for no reason? In the second point you say I'm interpreting the sentence. What exactly are you doing here? You are interpreting what Goku said without any valid reason. There is no evidence Goku lied here and there is no evidence to believe Akira Toriyama would increase two characters powers instead of make one weaker. Goku never lied about not being able to beat Fat Boo. Goku merely answered Piccolo with a "I don't know, I don't think I could beat Fat Boo..." this implies an uncertainty. Not a fact. Besides, he debunks his point by saying he wanted to let the kids try as he wasn't of this world any more. So he was clearly suggesting it was possible.

For the second point :

You are totally interpreting the sentence ! They never talked about his Ki ; Bejita is mocking Kid Buu's size, and Goku (who is totally stupid) respond. They make a big mistake by judging him by his size. Besides, when Kid Buu cries (and show a part of his Ki), they're not so confident. And this only when they faught Kid Buu that they realized their mistake. Goku said something like : "he's better than I thaught" and Bejita "How can Goku did a match against him ?? This Buu is terrible !"

I'm not interpreting this sentence at all. Vegeta is mocking Pure Boo's size, correct. But what did Goku say? "We did it!" Did what exactly? What was Goku and Vegeta trying to accomplish? Did Goku and Vegeta say they were trying to make them smaller? No, they didn't. Did Goku and Vegeta say they have to make him weaker or fuse? Yes they did. So the objective was Goku and Vegeta were trying to make Boo weaker. Goku says "We did it!" So they accomplished their objective.

And I return you the question : How can Super Buu be stronger than Kid Buu knowing that he's still under the influence of the Kaioshins, an evil version of Fat Buu ? (If it's something with the South Kaioshin...we see him only in one image of the manga, it's never suggested that he could be a source of power for Buu, so it's clearly an out-ouf universe argument...possible, but maybe more far off the manga than my argument against the Goku<Super Buu)

Does the East Kaioshin say South Kaioshin weakened Boo? No he doesn't. What has happened every time Boo has absorbed someone apart from Dai Kaioshin? Boo's power has increased. So are you telling me South Kaioshin had no effect on Boo? Let's look at it this way:

Absorbing effects

South Kaioshin - Unclear, not stated to weaken Boo.

Dai Kaioshin - Weaken Boo.

Good Boo - Strengthen Boo.

Gotenks - Strengthen Boo.

Gohan - Strengthen Boo.

As you can see the majority of the absorptions has increased Boo's power. I find it hard to believe that South Kaioshin did nothing for him, there would be no reason for him to absorb Dai Kaioshin if South Kaioshin didn't have a positive effect on Boo's power. We also have this:

Chapter: 507 (DBZ 313), P13.5
Context: as evil Boo reverts to his South Kaioshin form
Goku: “H-hey…Vegeta…His ki is increasing, ain’t it…!?”

As you can plainly see Boo's power increased when he got the South Kaioshin form. It is only when Buff Boo turned into Pure Boo that Goku said "We did it!" - in response to their goal of attempting to weaken him.
