Zamasu has the potential to surpass Whis.

[Yomi]

I will be mentioning episode 62-65 spoilers.
I want you guys, the experts of the Dragon Ball medium,
to tell me if my assertions are even within the realm of plausability.

From the title of episode 64, we know that Zamasu will merge bodies with Black Goku
presumably with the Potara earrings. In that case it would be fair to assume that both the traits of
Black Goku and Zamasu will be present in the Merged Zamasu.

On one hand, we have an undying body that instantaneously regenerates from any wounds.
On the other hand we have Black Goku, who's body is able to inexplicably give him Zenkai boost every time he receives damage.
Pain makes him stronger. Theoretically if Merged Zamasu has both of these attributes. Merged Zamasu's potential fighting ability
will be limitless.

PS: I'm assuming that Zamasu's wish can only be undone by the Super Dragon Balls. Which they have destroyed. In the other accessible timelines
they will take months to recharge.

With bodies like theirs. The idea of them fusing is becoming more and more threatening.
[spoiler][/spoiler]

But before I get excited about the possibility of seeing Whis or even the Grand Priest in battle. There's something at the back of my mind.
Something that could just alleviate this entire Zamasu situation with the click of a button.

Considering how Goku had a form that was supposed to be close to Beerus (at least more than half as strong) and yet with Kaio-ken x10 he was still implied to be below Beerus, I'm guessing the potara fusion won't give as much of a boost either as we might expect it to.

Though the Potara earrings multiplies the combine strength of the two users. With it, a super saiyan Vegito was significantly stronger than Super Buu who was fused with Gohan. I wouldn't be surprised if a merged Zamasu could be the strongest character next to Zeno.

I really doubt it. For now, it's nothing, but speculation until facts are seen. We don't even know what Beerus full power is. And Whis? we don't know ANYTHING about him.

I wouldn't be surprised if a merged Zamasu could be the strongest character next to Zeno.

Stronger than Grand priest etc? nah.

[Yomi]

Stronger than Grand priest etc? nah.

The point was, Black's power up style and Zamasu's immortality, could make them swell to that strength pretty rapidly if they keep those attributes when fused.

That's what you might expect, but DBS seems to be bucking the trend of previous powerups and making them mean less than you would think they wold.

The more I ponder about this thread, the more I think that the Mafuba is going to fail.

[Alehandrew]

I have a feeling the Zamasu/Black fusion will ruin the Mafuba plan. Either break one of them out of it to fuse or save one before getting trapped.

It's hard to imagine a SSB Vegito or Zamasu/Black fusion not at least being on the level of Whis.

[Rubens]

There's a chance the fusion won't be that effective because they're pretty much fusing two Zamasus (one has Goku's body but in spirit/ki they're both Zamasu) but that's just an hipothesis. However, based on Vegetto's scale of power I'd say it would be strange if Black+Zamasu combined wouldn't surpass Beerus, at the very least.

[fadeddreams5]

Potential, yeah, but he'd never reach it in a battle with Whis. Whis doesn't need to fight him. Just neutralize.

We don't know anything about Whis. He's only shown about 1% of his power and the feats he's done are ridiculous considering this.

[dblack]

I wish we'd of got more information on the Zamasu's killing all the gods.
The easiest way is they killed all the kaioshin, in turn killing all the gods of destruction.
I'd be interested in an episode showing them doing this, possibly Black killing one without taking out a kai. Maybe then foreshadowing stronger gods with Zamasu telling Black "maybe we kill uni 9's god's Kai because he would be too difficult of a battle."

If they do merge and get to Whis-level power, all I want is to see Whis take one punch. We've never seen him take any damage, a right uppercut to the stomach and an overkick to send him flying into a crater then a PO'd Whis-face would be epic.
