What happens if a SSJ4 loses their tail?

[GreatSaiyaman123]

Does he just revert to base?

[Kaboom]

It's what's happened when every Great Ape we've seen had their tail cut off, even for Golden Ape Baby in GT, so... the same thing would probably happen for someone in Super Saiyan 4, yeah.

[Yuji]

In GT, probably. In Daima, I'm not sure, considering how Goku doesn't even have a tail in base.

Daima really dropped the ball with that aspect of Ssj4. If he doesn't need a tail to reach the form or have it in base, why add it at all ? Just design Ssj4 without it. With Goku getting turned back into a kid, it would've been the perfect opportunity to have his tail naturally grow back as well. Remember, he said he figured out early on (before Daima's events) that Ssj4 existed, but just couldn't access it. Instead of Neva's magic, have his regrown tail be the key. I love Daima, but the more I think about it, the more I realize it was in desperate need of a second draft to iron out these types of issues.

For DBGT all logic seems to point that yes, he would lose the transformation, same as Ozaru.

For Daima, maybe it would not, as Yuji mentioned, since the tail does not need to be there for the transformation to occur, I think we can safely say that by cutting it, nothing would happen, besides hurting them that is. In other words I think it would be similar to getting an arm cut off, or losing any other limb.

Vegetath34th they added the tail to resemble the SSJ4 from GT.

I don't mind that the tail is not needed because it gives the SSJ a more kind of mystical origin, or at least it gives me the impression that Goku had to do some mental growing, in order to withold that much power, because SSJ3 was a transformation that (besides being ugly af) would cost Goku too much effort to keep. Daima SSJ4 is a way to reconnect with his primal saiyan form, that is why I say it is mystical.

They turn into cute girls and then beat each other up some more.

(There's no official answer and I doubt it really matters either way, you can tell any kind of story with any kind of answer).

Vegeta couldn't transform back into SSJ4 when he magically lost his tail for no reason at all. He could transform into his SSJ1 or SSJ2, so power wasn't a problem.
Goku couldn't transform at all, since his power was low. That is why he reverted back to base form when his fusion dance failed.

So in GT losing their tail means they lose their SSJ4 form and can't transform into that form.

In Daima losing their tail means nothing, since they just regrow their tail when they turn SSJ4 and their tail disappear when they revert back to normal form.

[Koitsukai]

Oddly enough, I think it wouldn't affect Goku.
He turns SS4 without needing the moon, the Earth, blutz waves or daylight and he even bypasses the ape form.
Vegeta, in turn, without a tail, only needed a blutz wave overdose that gave him a tail even.
I know he couldn't go back to SS4 due to the tail(yet he never said that was the reason, he said something else), but my elephant-man shaped headcanon is that the tail is key to make the form your own, but without it the body already has memory of it and should transform anyway.

The ape form depending on the tail, I think it's a different beast altogether. That form depends on the blutz waves, if there is no source for them, the form cannot be sustained or even be. SS4 doesn't need a blutz wave source, so I guess once unlocked, the tail is just a cool limb.
One could say that the tail retains the blutz waves and it allows SS4 to happen at any time, even if there are no blutz waves, but that was never the case with the giant apes. They never turned into Ohzarus at will like with SS4.

In Daima, I think is even less of an issue. Goku ended Daima without a tail(only as a SS4 he has it) and there were no mentions of him not being able to access it again because of that. But if we do bridge it with DBS, then it'd be a requirement.

Goku didn't have the energy to transform into any Super Saiyan form, when he reverted back to base form, since he was out of energy.

Vegeta didn't have any energy problem, he could still transform into his Super Saiyan form. The only form he couldn't access was SSJ4.
Vegeta needed the Blutz Wave to reach SSJ4.


I don't think Blutz Wave was the issue, since he used SSJ4 and mastered controlling that form. The only issue that I can think is his missing tail. That is the only difference between Goku and Vegeta.
