Future observation
Internal armament
So between these characters do you think they’ll get one, both, or no form of advanced haki?

- Zoro
- Sanji
- Kid
- Law
- Sabo
- Zoro probably won’t get either because while he specializes in armament the advanced internal form does seem to fit his cutting everything down kind of style. He has overflowing external haki with enma to make up for it tho. As for future sight i don't think he’ll have it but again his own unique observation haki upgrade
- Sanji also might not get either. When it comes to armament he might not the external version. While Luffy was training on advancing his armament to achieve the external + internal versions and Zoro was training with enma to overflow his external armament Sanji got an exoskeleton. When it comes to observation just because Gaban has future observation doesn’t mean Sanji will. Honestly similar to the exoskeleton he might stack his observations haki on some scientific upgrade
- Kid already mastered his fruit so I do think he’s next thing will be strengthening his haki like Luffy. It most likely being by achieving internal armament instead of future observation . 1 because it fits his style way more 2 most the greats have durability bypassing abilities
- Law same as kid but the opposite. With future observation fitting his style way more + he doesn’t really need internal armament him already being able to do that with his abilities
- Sabo lowkey might already have external armament tbh but either way even if he doesn’t imo it’s pretty likely he achieves both advanced forms. The internal armament boosting his dragon claw style and the future observation boosting his logia body further. Plus he gets the Luffy brother tax
