He becomes a super saiyan a few episodes after planet namek was destroyed
He ascends past it. He might be able to, but there is no reason to since it uses a lot of kai (which may be why he can't become one) and he is already a Super Saiyan 4.
Yes
There is no super saiyan 4, its only until super saiyan 3 (Broly,Vegeta,Goku and Gotenks). There are only characters of Dragon Ball Z Kai, not Dragon Ball GT.
Dragon Ball Z Kai episode 47
If he changed in Dragon Ball Z, then he will in Kai. Kai is simply a shorter repeat of the original DBZ
In the Majin Buu Saga after Buu was resurrected. When Vegeta was in the heavens after he died, he saw Goku go SS3 and accused Goku of mocking him with that transformation. In case you were looking for the episode number it was episode 245
gogeta shouldn't count because it is 2 fighters fused is should be one fighter and that's it and that would be goku because he can turn super saiyan 4 easily and vegeta needed a machine to do it and nobody else was close to super saiyan 4 level then that means omega shenron is because he is one person
Vegeta is actually Stronger, Its true that Gohan hit Super Saiyan 2 before anyone but that doesn't mean he is stronger than vegeta. Vegeta hit Super Saiyan 2 after the Cell games but he achieved it before becoming Majin Vegeta, During which he said to Goku "At least your stronger than your son was against Cell." which means Goku was stronger than Gohan and that means Vegeta was just as powerful also it is stated in the Dragon Ball Z series that Vegeta was the most powerful, second only to Goku. As for Gohan hitting Super Saiyan 4, he cannot. But Vegeta can't transform into a Super Saiyan 4 at will. So his transformations are actually up to Super Saiyan 2. But as for Gohan, the Elder Kai releases his deepest hidden powers, which make Gohan even stronger than a Super Saiyan 3. So actually Gohan is the stronger one.
find out your self he turnes super in 47 and ends the battle of freeza in 48
I don't think he can because the elder Kai released all of his power. The elder Kai told him to do what he does when he goes super saiyan and he became ultimate Gohan
Goku.
Probably not, it is hinted that only pure blooded saiyans can achieve SS4, When Goku turned SS4 it was because he absorbed Blutz waves, so did Baby Vegeta, and he didn't turn SS4 even though he was in Vegeta's body, who is a full blooded saiyan, the reason Baby Vegeta did not go SS4 was because Baby was a parasite in Vegeta's body, in a way they fused, so his blood was not 100% saiyan. So, i guess not =/ actually if you seen how goku became a super saiyan he transformed into his oozaru[big ape] form then regained control of himself thanks to the memories of pan then he turned into a super saiyan 4 so if gohan chose he could be a super saiyan 4 but he does not want to be a fighter like his dad Dude u are wrong on so many levels. u dont know anything about the dragon ball series. ofcoarse gohan can turn super saiyan 4. if hes able to go through the other 2 transformations and reach a level stronger then a super saiyan 3 which is his mystic level then ofcoarse its possible. gotenks is a half saiyan and he transformed into a super saiyan 3. the reason why they didnt let gohan transform into a super saiyan 3 in gt was because that series was all about goku. but if u realize that if gohan transformed into a super saiyan 4 he would be the strongest out there because he was born with a hidden ability. they just didnt let him fight and train to become a ss4. if anything bulma shouldve just used that blood suave machine on everybody. no. goku and vegeta are the only ones in the dbz universe that can turn ss4 unless broly or bardock came back to life.only pure blooded saiynes can turn ss4 the guy above is 100% wrong
