One piece universe would be more balanced out instead of marines stupidly being killed a hundred at a time by one df user
That would be too overpowered for fodder to have. Even Bege, a subordinate of a Yonko, said he didn't have access to something like that. Although he did have access to a seastone spear.
Once the Marines start crafting bullets like that, everyone would start. If all it took to bring down an Admiral or a yYonko was someone with a gun the whole balance of power would be ruined.
Oda had Z use a Sea Prism Stone bullet against Luffy. They must exist but don't use them. I do not think they should be used in every situation though.
Film Z was non-canon so that doesn't count. However, I think they were mentioned back in Impel Down when they fired at Crocodile and when their bullets didn't work someone yelled, "Quick get the seastone bullets!"
Too OP it would be a bloodbath , true marines would have them first , but then the pirates would get them as well . Rather think about this , Ben Beckman pointed a rifle at Kizaru , soo it is probably possible to use haki on bullets i dont see a reason why not. Same effect...
because you need fodders marines to make them look dumber and dumber because they suck they wouldn't even be a threat if they had keiroseki bullets also it's a huge waste of resources since keiroseki isn't a raw material to come across and would be smart to save it and make it permanent usage since it ain't cheap either
If I remember correctly the material is very scarce so they only use it for the more important things. I.e hand cuffs shackles, ship bottoms or whatever, nets and etc.
Cuz if snipers like usopp got a bunch of those the admirals are toast
What do you think?
