This is the only good point you've made this entire time. Good effort, finally.
However, it still doesn't deny getting energy from Gohan's stone state. In DBS we see that Old Kai dies when Dabura destroys the Z Sword that had been turned to stone. That should count as damage. So Dabura can...
Nope, they need to be in Babidi's ship or near the level portals to get the energy. Neither of those were the case for Piccolo and Krillin. They thought they were so weak it wouldn't be worth the trouble to get their energy, and decided to use them as bait to get the others to fight Dabura where...
Stop making things up. At no point is this ever stated nor is it supported in extra material. I dare you to find a quote to support it. It won't happen. You can't do it. Stop lying.
What's the point of this? I never said that.
Dabura was luring them in to the ship to fight. The only way to...
Vegeta deliberately spoke out to inspire Babidi to raise his power.
The fact that Dabura tried to kill Gohan with stone spit and the sword indicates that Dabura is not playing around. If Gohan were turned to stone, they'd get his energy. If Gohan got struck in the head with the sword, he'd die...
Babidi says they'll take "their" energy as in both Goku and Vegeta, so that's why it's better to use Vegeta. They seemed to only be taking Gohan's energy earlier, maybe they can't use Dabura's energy.
Dabura's mission is to damage Gohan. It doesn't make sense to hold back as that would mean...
Does Dabura call Vegeta the best fighter? I recall he calls Vegeta a splendid fighter.
It doesn't make sense that Dabura would hold back or suppress in the first battle with Gohan as the whole point is to cause damage to Gohan. He even tries to kill Gohan with a sword. Come on man.
Dabura suggested Vegeta be made a Majin out of convenience. Vegeta loudly proclaimed he wanted to fight Goku and Dabura took the bait to have the Earthlings fight each other for them.
Dabura being confident in beating Gohan doesn't have to be because he thinks he can one-shot Gohan or that he...
It's never said Dabura wasn't using full effort. Your scan doesn't say anything like that.
There's other material that says Gohan was superior in power to Dabura but was having trouble because of rusty skills(Dragon Box book).
The only thing that matters is that Future Dabura is shown being on Z Sword SSJ Trunks' level, so it doesn't matter how he got that way. It is what it is. You are using an argument from incredulity. Your incredulousness is irrelevant.
Buu punching rocks is paltry in comparison to the battles he's had before. The point is he got stronger from exertion.
I never said each battle gives a big improvement.
It's not a zenkai to become stronger or fitter after physical exertion. A fight is physical exertion. Saiyans just have the near death zenkai and they sometimes gain more per fight than others.
Mr. Buu in DBS became base Goku's level after training for a few hours with Mr. Satan throwing rocks...
