Robin is the most likely too get haki first she's been around dragon for two years and she has perfect understanding of how haki works soo it feels like Oda have already been giving us hints that she will get it and she's been showing more and more and more hints that she's about to unlock it soon she clearly knows herself that she needs it.

Franky is the member who needs haki the least homie is a cyborg with tons of weapons and literally is made of metal😂.

Nami and usopp are unlikely to get armament haki usopp has observational haki and nami may get that brooke might get two types or observational Robin is getting armament thats clear and all those years on the run suggests she will get observational haki too

God Usopp&Garp the fist are gods without devil fruits though.

Luffy,Imu,loki&Sengoku are probably the only god devil fruit users.

Dragon might have a god fruit but i think its more likely that he has probably got the easteast fruit making him prone to facing east and controls everything to the east like the east winds,sea,space😂😂😂

Top contenders are Bonney,Lilith,Yamato,Vivi,Loki in that order as of rn Loki is the least likely to join ppl saying luffy asked everyone hes asked joins which is factually wrong weres zombie tree and zombie zebra or chest guy etcetc he will probably join the strawhat grand fleet though.

Vivi is just too weak at this point she would only get in their way on the ship but she could serve a great purpose with the grand fleet.

Yamato said she wanted to explore and go on her own adventure in wano first then she would join the crew so at some point she will 100% join the crew might be off screen after the story has concluded though.

Lilith is a scientist and inventor and really the only one with a clear role she's obviously up to something on elbaf my guess would be making a clone of stella which would effectively leave her free too team up with the strawhats.

Bonney is the obvious first choice for many reasons the only thing against it would be she got no clear role and she wants to sail around the world with kuma.

I gotta be honest your over glazing dragon abit here at times. Like if he hadn't saved shanks luffy would be dead that's just false because shanks is the reason luffy even got into that situation too begin with.

But its dragon ge finally stopped looking east and did something soo ill allow it 🤣🤣🤣

Lmao not the fishmen and female discrimination😂😂😂

Jimbei is arguably stronger than sanji currently and Robin has become quite the powerhouse.

Nami can one shot luffy😂.

Only usopp and chopper are weak on the crew tbh but usopps strenght is sniping not close combat and choppers the doctor.
