Gogeta started out in base, and when it came to using SSJB against Broly he was always comfortably ahead so didn't need to be going all out. We know Vegetto went in with the intention of killing somebody he believed to be immortal, but he did dick around. Also, there's the very likely option that CSSJB just effects fusion differently since the power isn't leaking out. Anyway, that doesn't matter either. Final KHH should definitely be stronger (pound for pound) than a regular KHH like Gogeta used so that would put more strain on the fusions current level. Fusion's weird. We know that different forms strain it in different ways. Like SSJ Vegetto lasted a full hour (apparently), and SSJ Gogeta lasts half an hour. The likes of Gotenks as a SSJ3 can last 5 minutes, and it cancels their fusion although being much weaker than either of the other two. So fusion doesn't just come undone because of power, but because of strains from different forms placed on the fusions current level. So SSJB Vegetto at a higher level not outputting as much energy would last longer than a weaker version in SSJB constantly using more energy. So there's always the option that he tried to power up to his maximum power, but then defused because it put too much strain on the fusion because the incomplete SSJB was draining him... I guess thats where a CSSJB would last longer.ZombieVito wrote: ↑Sun Sep 22, 2019 12:22 am 1) I know they are equal but that doesn't work with the manga. Vegetto couldn't even hold his fusion for any significant time when facing a much weaker opponent while Gogeta did so when facing someone on his level. Even if their powers are the same, this fact makes Vegetto inferior since he can't hold his fusion for long while Gogeta can.
This is not a problem with the anime since it makes sense for Vegetto to defuse there.
Anywho, this parts the interesting bit.
The main evidence we have of how long Vegetto lasted comes from this. Gowasu states "If only Goku could last an hour" whilst fighting Zamasu immediately prior to Vegetto coming to be, then almost immediately after they defuse Trunks asks how long is left, and we're told theres about 20 minutes until Zamasu defuses. So yeah, I know the Vegetto fight was extended a little in the manga later but not to the stage where that makes sense. So looks like Toyo just did an extremely piss poor job there of portraying how long Vegetto was actually around. But yeah, he was around for plenty of time, just seems like he dicked around a lot more than we actually got to see. That final bit of info is an interesting one, and until Vegetto came to be Zamasu wasn't around for that long at all according to Gowasu, probably 10 minutes at best, and Vegetto was around for quite a while in the end.
