Well, before I get started on the evidence against this notion, I'll go over the previously mentioned evidence for it. 1) The Supreme Kai's statement. 2) Uh... there is no two.Kaioshin basically referred to Freeza as a pathetic scrub.
When Pui Pui started showing off, Kaioshin freaked out and started talking about teamwork. And Vegeta still effortlessly takes Pui Pui down. Again, Kaioshin said he could have taken Freeza out in one hit. Not "could have probably beaten in a fight." One. Single. Blow. So unless he's lying out the ass, he's at least as strong as SSJ Trunks when he first showed up.
So someone as strong as a run of the mill SSJ1 would come face to face with someone of, as Horgus put it, Kewi's level and be afraid? THAT is the single most ridiculous assumption I've heard in this thread.
Do you have a conflicting quote or specific flaw in the evidence? If so I'd love to hear it. That's the point of a debate. But if not, I take offense to the implication of stupidity based on a gut feeling of "Nahhh Pui Pui didn't seem that badass."
Alright then. Let's go for the evidence against it now. First of all, I'm sure we can all agree on this one point at least. The Supreme Kai's ki sensing skills... for lack of a better word... blow. Let's face it, he was face to face with SSJ2 Gohan at the tourament. He's got first had experience with that power. And yet he's afraid of Pui Pui?
Obviously base Vegeta is stronger than SSJ2 Gohan because obviously Pui Pui is stronger than what he sensed from Gohan at the tournament. Of course, we know this not to be true, so obviously there must be some other thing at work here. Why, then, would the Supreme Kai freak out over Pui Pui if he's witnessed a power far greater than the alien's?
It's pretty simple, really. Pui Pui wasn't just some alien. He was an alien under Babidi's control. He was a Majin. He was the one thing the Supreme Kai feared in the entire universe. He's 'Majinphobic' if you will. And why wouldn't he be? He witnessed Majin Buu decimate a large portion of the universe and completely overwhelm and kill his fellow Kais.
So, the Supreme Kai's terror is completely and utterly self induced from phobia. He's standing feet away from several beings more powerful than Pui Pui. He's witnessed Gohan's SSJ2 power before. If he had any true ki sensing abilities or paid any kind of attention to what was going on he'd already know that Pui Pui was pathetically weak compred to himself and his allies.
The Supreme Kai never, during the course of the entire series, shows any kind of aptitude with ki sensing. He's wrong. Every time. Over and over again. His comments should basicly be ignored because he's about as good an indicator as asking Hercule.
This would be the other point against that kind of power being needed. Your point is decent, but invalid. It was invalidated earlier in the story when Trunks was in with Vegeta. Trunks was walking with only slight trouble in 150Gs. Then he transformed into a Super Saiya-jin and 150Gs became like nothing to him. Obviously power is enough to override the effects of high gravity.Horgus and caejones, being comfortable in "only" 10gs has nothing to do with power- put Goku in a 400g environment and suddenly Vegeta would have an advantage. Gravity training is similar in theory to weighted training. You get used to a higher level, and you find yourself that much faster, stronger, and more durable when restored to normal levels. And the only thing they say on Pui Pui is that his homeworld was 10 times earth gravity. They failed because they didn't know Vegeta had gone through intense gravity training, not because Pui Pui "could only handle..."
The fact Pui Pui assumed that 10Gs would be enough to incapacitate or slow Vegeta to the point he could defeat him speaks volumes about his own power. If he was exceptionally powerful he would know that Vegeta was as well, just by how easily he was being knocked around, and he would know that 10Gs would not have the effect he assumed it would.
