The second-generation serum was far gentler than the third-generation one. Though the pirate who received it could feel pain throughout his body, it remained within tolerable limits.
Under the serum's effects, the skin on the pirate's back became extremely rough before eventually hardening into layers of scales.
His fingers also became thicker than before, though his facial features did not change much. Through this serum, the pirate successfully gained a unique "biological exoskeleton."
"Worororo, so this is the second-generation serum? It looks pretty decent. I can accept this much."
"Mm, it should be a pangolin. Kaido, perhaps we could try specifying the animal. That would strengthen our combat power more effectively."
Queen possessed considerable biological knowledge. From the changes in the pirate's back scales, he had already identified the source of the ability, but he soon realized there was another problem.
This was not a Devil Fruit. Without an encyclopedia, there was no way to know what ability was inside.
Since it was artificially produced, there should be a way to designate the species.

"Jack, it's not your fault. The enemy was too strong."
In the end, Kaido alone got to decide how this sort of thing was judged.
Someone Kaido valued could point at his nose
