Luffy’s g4 basically being his awakening before his true awakening is a pretty basic take but imo it has an even more interesting connection with zoro and sanji
Off the bat armament haki is necessary for each form. So without haki theyd be incapable of using it
- Luffy hardens his body while being able to keep its rubber properties
- Zoro unleashes extra powerful armament infused slashes
- Sanji stacks his armament and exoskeleton durability to create even hotter flames
It’d be interesting if there next step similar to luffy post timeskip end up being to further advance their observation haki
Shiryu and laffitte lowkey potentially being the perfect characters for that. Maybe relating to see no evil hear no evil
If the pattern continues and they next further develop their armament. Zoro making a black blade and sanji maybe black flames or at least using hardening lol. Against who specifically they’ll advance their armament to face? Idk
Zoro maybe mihawk and sanji idk idk Kuzan? Beckman? Someone else?
Next being conquerors again only if it becomes a pattern. Unpopular opinion but I can see Sanji getting conquerors sooner rather than later even this arc. If he eventually is able to infuse it with his attacks idk
Maybe at this point they will show off that they can split the sky while in clashes idk. Not really a specific power up but could
For Zoro maybe fully mastering asura or a stronger form he can actually use for a long period of time. Possibly being through him getting shodai. Basically zoro mastering the peak of “cursed” blades like luffy mastered the peak of his fruit
For Sanji maybe a perfected raid suit. Bring it back to all the science and lineage factor stuff Sanji has going on. This suit actually being made out of love for him and being able to boost all his abilities
I only really focused on zoro and sanji but there’s definitely a chance Luffy can advance his haki’s again even further. His is just harder to guess
