My idea is just that in Universe 7, Gohan trains with Gast Carcohl and grows up to be similar to his Universe 12 counterpart but around as powerful as Universe 16/18 counterpart. Gast Carcohl also gets psychic powers. U7 Gohan competes in U3 Bardock's place. That does not go against what was established before U3 Bardock appeared. Does it go against what was established after he appeared? Yes, but that's the point. Does that go against what the manga established? Doubt it; explain how it does.
You have yet to state how that is possible without the Old Kaioshin. Your belief has no basis. Ergo it is baseless. Gast kills Boo so there was never a need for Gohan to pull the Z Sword. So that rules out Gohan going to the Kaioshin realm. Mortals are not supposed to be allowed in the Kaioshin realm and since Boo was dealt with By Gast, Gohan would never go to the Kaioshin realm.
It's definitely possible. There could be another being with powers similar or greater to the Old Kai. Do we know if there is? No, but that doesn't matter ... since we don't know of one, I can come up with one. It's an IDEA. Gast may have killed Buu, but that doesn't mean Gohan wouldn't have pulled out the Zeta Sword. The options on how the Buu arc played out in Universe 7 are almost endless here.
So how are they different and how does that make a possible U7 Gohan relevant at all. You need to make a difference. My point of using F. Gohan training is that the mountain training never did that much for him. Even with ROSAT time Gohan would still not reach the potential he has normally. Gast has no understanding of Super Saiyans so he would have no idea how to get Gohan to even transform into a SSJ3. And even if he could that would still pale in comparison to Gohans power up from the Elder Kaioshin.
Events obviously happened differently in Universe 7 than in Universe 12. Depending on how they occur, Gohan would become like U12 counterpart and fight in the tournament. We don't know if Gast has understanding of Super Saiyans or not, so the story could just make it so he DOES have understanding about them. And again, there could be another method that Gast could use to get Gohan as strong as his U16/U18 counterpart.
What use does Gast have for Gohan? Gohan is a worthless meat bag in comparison to him and can't help him in any way, shape or form. Gohan would not abandon his father because of Gast. Gohan has always hated fighting. He loves to study and prefers it over fighting. He isn't going to leave earth for 4 years just for Gast. He is a boy. You yet to raise even a single point why anyone should care about another Gohan showing up and adding nothing.
Gohan offered to help Gast in any way. Traveling with him could be part of helping him. We don't know if Gohan's
always hated fighting; at just 5 he probably doesn't realize how much he hates it. Gohan is a boy, yes. So, he might make decisions recklessly.
Just go check out Gast and Palz. It's more consistent then what your coming up with. Take the time to write out everything you want and create a thread for it in the fan created works. Write down your plot, characters, ideas, and then submit it in a new thread. If you really want your idea to work, you can have forum members help you iron out inconsistencies.
My idea obviously can't work at this point. We got U3 Bardock instead of U7 Gohan. We're past the first round. I was saying that "INSTEAD of getting U3 bardock, we SHOULD have got U7 Gohan who is similar to his U12 counterpart in personality and look but his U16/U18 counterpart in strength".
You do not understand what can be done with an idea. It doesn't matter if we don't know something based on the evidence we currently have when making an idea. When you have an idea on how the story should be, you MAKE UP how the story should be. Part of what I'm doing is changing the story of Dragonball Multivierse, too.
The world's greatest.
