Some questions about Majin Boo saga

[Dio Brando]

I was re-reading the Majin Boo saga, and some questions sprung into my mind: usually DB is pretty good on answering specific plot points, but after the Cell saga, it began to lose this characteristic.

1 - After Gohan shows his power on the tournament, and Kaioshin goes after Babidi, he mentions "If I knew he was so strong, I could have used that other way...". Was it ever answered what was he talking about? I understand DB has a lot of those unanswered questions, so if you have just a personal theory, I won't mind.
I'm under the impression he was going to teach Gohan on how to use the Z-Sword to destroy the Majin Boo egg, but since that plot device is only brought later into the series, that may not be the case.

2 - What really happened after Boo and Bibidi killed the other Kais? I've read the DB wiki, but a lot of the topics there seem pretty farfetched - I have the manga and there's no mention of even half the story in the DB wiki. What I know is, that after Boo killed the Kais, Bibidi sealed him in the sphere. But did he transport him to Earth, or was that Kaioshin's doing?

3 - The great question is: did Kaioshin kill Bibidi after he just sealed Boo, or after Bibidi came back to Earth to unseal Majin Boo? I ask this, because it's hinted that Bibidi sealed Boo inside the sphere from time to time, so he would fear him (even the Kid form).

4 - How much time before DB did Bibidi really exist? Kaioshin says that they hid Boo's egg just when humanity was beginning to flourish, so that may be a lot of time.

5 - Were both the sphere and the ship hidden on Earth, or just the sphere? From the anime, you can see Babidi found the ship somewhere else, then came to Earth, found the sphere, and hid it inside the ship.

2/3. Buu's sphere was brought to earth by Bibidi, because Earth was his next target. Bibidi used the sphere as a way to transport buu from planet to planet, so he presumably sealed Buu many times before Supreme Kai caught him.

4. H. sapiens is only 200,000 years old, but other species of humans were around as far back as two million years. That's our Earth, though.

5. Just the sphere. The ship is Babidi's that he came to Earth on looking for Buu.

Not that I can recall. Your idea is pretty interesting, tho. I honestly always figured Kaioshin would've simply took Gohan to his homeworld immediately, and have him release the sword in order to finish Boo whenever he would be released. But, when looking at your idea, it makes more sense.

I've read the DB wiki, but a lot of the topics there seem pretty farfetched - I have the manga and there's no mention of even half the story in the DB wiki. What I know is, that after Boo killed the Kais, Bibidi sealed him in the sphere. But did he transport him to Earth, or was that Kaioshin's doing?

After they attacked the Kaioshin planet, I believe they went on to continue their destruction. Boo did mention to Hercule how Bibbidi and Bobbidi constantly told him that destruction was fun or something--so that implies he still continued to destroy after he absorbed Dai Kaioshin. And I believe Bibbidi had took Boo's sphere to earth and planned to destroy the planet. Kaioshin just happened to find him there and take him out. So, Bibidi took Boo to earth.

3 - The great question is: did Kaioshin kill Bibbidi after he just sealed Boo, or after Bibidi came back to Earth to unseal Majin Boo? I ask this, because it's hinted that Bibidi sealed Boo inside the sphere from time to time, so he would fear him (even the Kid form).

It seems like it would be the latter. Kaioshin knew he was about to unseal him, so he took his chance before that could take place.

4 - How much time before DB did Bibidi really exist? Kaioshin says that they hid Boo's egg just when humanity was beginning to flourish, so that may be a lot of time.

A very long time. Hell, Dabra implies he was under Bobbidi's order for at least 300 yrs. So, imagine this was like, gazillion yrs before.

5 - Were both the sphere and the ship hidden on Earth, or just the sphere? From the anime, you can see Babidi found the ship somewhere else, then came to Earth, found the sphere, and hid it inside the ship.

I'm guessing Kaioshin most likely destroyed Bibbidi's ship, so I think the sphere was the only thing hidden on earth. The ship was Bobbidi's ship.

I don't see any reason not to assume he was talking about the Z Sword, since that's the first thing he mentions once Kibito heals him following his fight with Boo. That's only 9 chapters later. I know Toriyama has a reputation for not planning ahead (and often this was true), but if he could plan Piccolo being a Namekian all the way back before the 23rd TB, I don't see why we can't assume he planned this out.

I've read the DB wiki, but a lot of the topics there seem pretty farfetched - I have the manga and there's no mention of even half the story in the DB wiki.

The DB wikia is complete shit, and generally gets everything wrong but the blatantly obvious (and will sometimes even screw that up). So don't trust anything they say if it's not in the manga. Anyway, in the manga Kibito flat-out says that Bibidi sent Boo's ball to Earth, during the part where he and Kaioshin explain Boo's history.

3 - The great question is: did Kaioshin kill Bibidi after he just sealed Boo, or after Bibidi came back to Earth to unseal Majin Boo? I ask this, because it's hinted that Bibidi sealed Boo inside the sphere from time to time, so he would fear him (even the Kid form).

Kibito's phrasing in Japanese is that Bibidi took Boo's ball to Earth, at which point Kaioshin killed him. I think it's the same in Viz.

4 - How much time before DB did Bibidi really exist? Kaioshin says that they hid Boo's egg just when humanity was beginning to flourish, so that may be a lot of time.

In the manga, the exact phrase is that Boo was sent to Earth "when humanity on Earth had just begun to walk on two legs". Daizenshuu 7's timeline places this at about 5 million years before the story of DB. Kibito says that the reason Babidi needed so much pure energy to revive Boo is because Boo had been sealed away for so long, the implication being that Bididi never needed to go through the tedious task of gathering all that energy back when he was sealing and unsealing Boo.

5 - Were both the sphere and the ship hidden on Earth, or just the sphere? From the anime, you can see Babidi found the ship somewhere else, then came to Earth, found the sphere, and hid it inside the ship.

Since Bibidi came to Earth, it would make sense that he used some ship to get there, though maybe he just used magic to teleport (which I think is what he's shown doing in the anime). Anyway, nothing is said about Babidi's ship being inherited from his father. And Kibito says that it was Babidi who hid his ship, which was why the ground around it looked different from the surrounding area; it had recently been dug up.
