Goku's inconsistent power

[Future Warrior]

This is gonna be similar to me ranting on how inconsistent Goku Black's power is, only it's Goku this time.

Lets start this off by analyzing quotes from the ROF arc.

Gohan: ''They both have unbelievably strong power''
Kuririn: ''This is indeed different from the fight with Beerus''

Both of them are astonished of Final Form Freeza and Base Goku's battle power, and it's implied by Kuririn that the fight with SSG Goku and Beerus isn't as comparable as this fight. They have already sensed SS Goku's Ki when fighting Beerus, which retained the power of a SSG at full potential. This tells us that Base Goku is stronger than he was as a Super Saiyan God against Beerus.

Base Goku (ROF) > SSG Goku (BOG)

Seems legit. This makes the Super Saiyan Blue transformation a small increase since SSB is still weaker than Beerus.

All is fine until the Universe 6 arc where Goku and Vegeta are capable of turning normal SS. This creates confusion since using SS multipliers that would put him above Beerus, even though that's not the case. Some theories suggest that Vegeta and Goku are capable of accessing two states, one being normal form and the other being Saiyan Beyond God form. This would explain why Piccolo and Good Boo would be considered to be useful in the Tournament. Now I would be abide by this theory if it wasn't for the Future Trunks arc.

If Goku and Vegeta are capable of switching their God Ki off, then Black would be a completely useless villain even though they considered him to be a genuine threat. Not to mention the fact that SS2 Goku was stated to be God tier from Gowasu, and Beerus stating SS2 Trunks to be ''quite good'' which he said no such thing to SS3 Goku.

This is a total mess

"Different" sounds kind of vague. I would just use Base Vegeta tanking SSJ3 Gotenks as an indication on where the Base Saiyans stand in power and go on from there giving each of the SSJ forms their respective multiplier.

It's because Beerus got retconned to be worlds above the Saiyans. It's only inconsistent because we were used to Beerus being in the same tier

Not at all, the power that Goku absorbed SSG is not gonna stay there forever.

Minute: 17
Context: Whis provides highly detailed expository dialogue.
Oracle Fish: "Maybe your training is a bit too tough? At this rate, those two are going to die. You could at least have them become those "Super Saiyan" things."
Whis: "That wouldn't do, at all."
Oracle Fish: "It wouldn't?"
Whis: "Those two have just barely reached the level where they can sense the ki of a god. If that castle up there were the level of the gods, then their power is only about this high. They need to raise the level of their ki without becoming Super Saiyan. Otherwise, they won't be able to grow much stronger, since they won't be able to see the realm which lies ahead. Most likely, those two realize this themselves. After all, I never once told them not to become Super Saiyans."
Oracle Fish: "Well, whatever. Just don't kill them."

Significance:
Whis' explanation reaffirms Toriyama's statement made in Saikyō Jump's June 2014 issue, quoted below:

Akira Toriyama-sensei - Majin Buu Arc Top-Secret Q&A! wrote:
Goku endlessly keeps getting stronger, with Super Saiyan 3 in the manga and Super Saiyan 4 in the anime; does Super Saiyan keep getting limitlessly stronger too? Might we eventually see things such as a Super Saiyan 5…?!
Super Saiyan 2 and 3 are nothing more than powered-up variations of Super Saiyan. After the fight with Beerus, Goku realized that mastering his normal state and Super Saiyan would raise his level more and sap less strength, so I think he probably won’t become Super Saiyan 2 or 3 any more.

So in other words, Base Goku is not in the league of the gods he's just barely there.

 

[xmysticgohanx]

There's nothing stopping SSJ god Goku from being there as well

During Goku's fight with Frieza he was using Saiyan Beyond god. It was his way of tapping into the powers of a Super Saiyan god without actually transforming into the form, which he was later able to perform in the Universe 6 and 7 tournament.

I don't see where your confused on that last part. Super Saiyan 2 Goku is still much much much stronger than what he was at the beginning of Super. So it's no surprising for Beerus to say that Future Trunks is "quite good." As for Goku Black, I think the only ones who saw him as a "threat" were Beerus, Whis, and Future Trunks. Future Trunks should be for painfully obvious reasons. But Beerus and Whis were mainly concerned about the Time Ring he was wielding.

Then back to what I was saying about Goku using Saiyan Beyond god is that I don't like calling that the "two base theory." Because Goku obviously is not using god ki, as you already stated in your opening post that Krillin could sense Goku's energy against Frieza. But is still a gateway power to Super Saiyan Blue. The way I look at the form is that it's very similar to Gohan's Ultimate form.

At Beerus' current level of power I wonder why he'd want to fight a mere ssg to begin with. I guess he won't be kamized at this point.

 

[Animelover5487]

I know it's weird Beerus went through all of that to fight someone he's actually 20+ times stronger then.

 

[Let's Go Fearless!]

Well Beerus saw the potential of Goku and Vegeta so that's probably the reason in order for Saiyajins to push their limits.

As far as Goku's inconsistent power goes, I think Toriyama was trying to address that when Goku's ki went out of whack after using KK with god ki at the tournament.... But not really cause Goku and Vegeta have inconsistent ki throughout the series, so that doesn't address Vegeta, plus I know that whole thing had to do with Goku using KK again. But still I feel like that was his way of somewhat addressing that.

Who am I kidding, Toriyama could never be that deep. If he was, there wouldn't be such crazy inconsistencies to begin with.
