I know lunarians are not mentioned a chapter and that's the point. Unfortunately, there are some fans pushing this belief lunarians are weak to lasers attacks and Queen could easily defeat King just because Vegapunk was concerned about a laser attack being used against jinbe seraphim, since he is still a kid and they haven't experimented lasers on him.
Most of them are just messing with you guys, ignore them
I'm counting their agenda that even if seraphim are weak to lasers, the manga doesn't say they are, it doesn't mean the same is true for lunarians. Seraphim are a scientific experiment that possess lunarian traits.
I agree with you, however the opposite holds true.
Lunarians might be vulnerable to lasers while seraphims might not. It would be a good reason to explain why Vegapunk is concerned by laser attacks
I'm not saying they are, and nothing implies directly that they are, but they might be.
The manga even talks about more tests are needed to determine how strong their traits are.
I don't think they specified this in the chapter but I might be wrong. They are still PX, not just artificial lunarians.
