Plotarmor Luffy, lmao, so fitting! Considering that the straw hat has been shared with Roger and Shanks, he needs a new one, doubt he will get it tho.
Death dealer Zoro or Demon Zoro may be something fitting. PH is really outdated.
Invisible Nosebleed-kun may be fitting for Sanji.

Flames, invisibility, masked are kinda contrary so not sure what he could get.
Nami hasnt been stealing in a while. Thunder navigator Nami or something like that. Thunder babe.
Sniper godo, Usoppu is fitting.
Monster Choppaemon, as Tyrion Lannister says: wear it like armor, dont forget it, the world wont.
Demon Archaeologist, Robin. The vengeance of Ohara.
Cyborg Franky, unchanged.
Hard to change Brook's Soul King, nothing that seems more fitting...
Sea lord Jinbe!
