With the recent chapters of Boruto, I think it has become more clear that cyborgs can indeed be much more powerful than Jigen.
Examples include Delta matching SPSM Naruto.
Code is stated as being more stronger than Delta even with his limiters.
And without his limiters scales above Jigen.
And we know that Amado stated that the cyborgs were created to surpass Jigen.
We see that Kashin Koji was confident that he could take down Delta.
This is consistent with him taking on 10% Jigen. Who at full power scales far above 201.7 Exatons (
Half of this calc). 10% of this should give 20 Exatons (
Multi-Continental level+), but this is far below even Delta who he was confident in taking on (The dialogue of Amado implied he had to save his strength to fight Jigen). So it should be assumed that Jigen even at 10% should be 5-C (201.7 Exatons) as he stomped Naruto and Sasuke while not even going all out. This would make the chain, Delta (5-C) = Kashin Koji (5-C) = 10% Jigen (5-C)
So my proposal, Kashin Koji should be upgraded to 5-C (
Moon level).
[Bonus]
10% Jigen scales to 201.7 Exatons, which means 100% Jigen should scale to 2 Zettatons (
Small Planet level), Ishhiki should scale above 2 Zettatons as he's far stronger than 100% Jigen.
Since base Kashin Koji can use Sage Mode, he should also get a 10x multiplier and should scale to 2 Zettatons, which Ishhiki upscales from stomping KK.
Baryon Mode Naruto is the only one besides Isshiki and Sage Mode KK who would scale to this.
(Tho this part is not mandatory and can be discussed later)
I pray this goes well.
