Hypothetically how powerful would a ssjgodssj4 be?

[Berserker1921]

Now I understand this is a bit crazy asking this. But how powerful would goku or Vegeta be? I mean toriyama stated he won't go to ssj2 and 3 because they drain too much power. But if memory serves ssj4 was perfect.

Who knows? With Super Saiyan God Super Saiyan, all that's really happening is Goku using the Super Saiyan form to channel Super Saiyan God's power. It doesn't seem like it actually makes him stronger, and Super Saiyan 2 or 3 might be the same way; just changing form and wasting energy without actually gaining more power. Which would kind of fit with what Toriyama said about Goku's training goals after Battle of Gods.

But Super Saiyan 4 might be a little different since it introduces Oozaru's power into the mix, too. It's hard to tell just how they would mix.

SSGSS seems to be stronger than SSG, but less than x2*. Toriyama said that Goku won't be using SS2 & SS3 after SSG because they drain too much ki, implying that the boost he would get won't be big enough for it to worth the ki drain, like Super Saiyan Grade 2, and unlike SS2 & SS3 before SSG. SS4 did have ki drain as well, though not in SS3 levels, but in bigger level than SS2, since it made Fusion last for 10 minutes instead of 30, and after Goku used too much ki, he reverted back to base after some time. So, if SSGSS2 & SSGSS3 are useless, the same would probably go for SSGSS4.

*After Goku absorbed the power of Super Saiyan God, he became a Saiyan beyond God, which made him insignificantly weaker than SSG (the difference is so small that he didn't have to use SSG anymore even though he could still transform on his own), and made his normal SS forms powerless. The only way for him to become significantly stronger through transforming is by combining Super Saiyan & Super Saiyan God, but the increase is less than x2, since SSG Goku was a 6, Beerus was a 10, and SSGSS Goku & SSGSS Vegeta together would have been strong enough to rival Beerus.

I think a Super-Saiyajin 4 is a Super-Saiyajin God powered "Super-Saiyajin" (more or less, no actually SSJ that is a part of the chain, just as what was known already) that has channeled the Great Ape Super -Saiyajin God power so exactly the same. This can also be used to explain the red hair, not that it was necessary.

Perhaps 10 times as strong as regular SSGSS? That's the only thing I could think at the moment. He would probably be the most powerful being in Dragon Ball's story.

Considering how SSJ is no longer sought out for its stunning 50x multiplier, but rather for the purpose of tapping into a larger extent of power absorbed from SSG, I wouldn't be surprised if becoming an SSJ4 only subtly amplified the user's power. By subtly, I mean like 2-3x.

With that said, the Oozaru powers may grant an additional boost and/or multiplier of its own that was unable to be grasped through previous transformations.

Multiversal+ imo
