That's why i started to doubt the story all together.

no. read it again,it says they were originally brought from mexico when they were kids. its in the black text at the top.

they have papers from mexico, it says they were originally from there in the same quote im referencing to.

If they have papers from Mexico, then they have a known Country of Origin that would have been found by Homeland Security or told by the immigrants themselves.

That means the second half of the story couldn't have happened, because by law they would have to be sent to Mexico, not file paperwork to send them somewhere that is different from their Country of Origin.

That's why i started to doubt the story all together.

I fucking heard it.

I was only upset because out of all of these names, they didnt have Kyle. I was like wtf...Especially when you talked to that one guy in sanctuary and he says "my sons name was Kyle"

I don't remember that one line. Even so, just watching it isn't enough to know how to do it. It would take practice and you would have to know the trick of doing it. It is more than just a dance. If it was as simple as watching it being done, then Trunks and Goten would have been able to do it without messing up all those times. There is also the problem of time. There wasn't enough time to perform the dance. Buu was intent on killing them and wasn't going to give them a chance to do it. Even after the split from Vegito, Kid Buu definitely would have not waited for them to fuse.

"the principle is the same as the Fusion technique, but the effect is greater than Fusion."
That doesn't say it's stronger. It just says it's more effective. It is more effective because there is no time limit.

"*Furthermore, after merging the power is greater than with Fusion."*"
Going to have to ask for a source on this. I know there are many guide books, but many of them are inconsistent and/or say things that differ from the show/manga. I'm going off things that are said or done in the show and canon movies. No where in the show does it say Potara fusion produces a stronger fighter.

I'm not trying to say that Vegeta has a perfect knowledge of the Dance itself, but he at least knows of it existing and the basics of how it works.

While the technique is more than just the dance, there is really only two parts. Mastering the physical movements (which is done in practice), and mastering the energy to match each other (which is done in practice, but Goku and Vegeta has mastered this since Namek)

Goten and Trunks only messed up twice in the Buu Arc, and both times were due to messing up the physical movements (the first time, Trunks used fingers instead of a fist in the second step, and the second time, both fingers were slightly off in the last step). Afterwards, they had a 100% success rate.

So the hard part is really mastering the dance itself.

"There is also the problem of time"
At that point, Buu didn't hunt them down yet, and neither of them knew that Buu can jump in his own body.

"It just says more effective"
(The quote is from Daizenshuu 4 - Technology & Supernatural Section btw), Effective could be either the time limit or raw power on its own.
