Again my awesome theories ;D.
Amazone Lily: Hancock
Past:
Shown. A small part but shown. And yeah it's terrible.
Reasons she can join: Female
**Friendly with Luffy
Chopper cute kick jokes
Sanji jokes
Past
Luffy has a debt to pay. For making a ruckus + Marines saw her being worried and attacked Smoker.
Reasons she can't join:
No dream(yet).
Has her obligation towards Amazone Lily if keeping her status.
Being shown in the 0 arc. With other Schichibukai gives me something she will stay as one.** No dream yet Own Opinion
She has a past, But enough to join? It kind felt as a Vivi. If I have to be honest now. I was a Hancock fan. But now… no... I don't think she can't join.
Margareth well she has some things but is just a character who isn't worth to mention anymore. Only when we get an AL post arc.
**Impel Down /War allies:
Buggy** and Mr.3 will start their own crew. So no-go for them.
Jimbei Hancock
Past:
Not yet, but could be something that has to do with Fisher Tiger.
Reasons he can join: Male
**Friendly with Luffy
Has a more Nakama feeling
The Eye contact.
Is worried about Luffy. And has some obligation feeling towards him about Arlong.
Reasons he can't join:
No dream and past (yet).
His obligation towards Whitebeard and Ace.** Own Opinion
Has a better felling than Hancock. And I could see him more as a Nakama right now. Only his strength could be a drawback. But I think there is more thatn that to see. I mean, Franky and Robin were monsters also so yeah.. he could be "nerfed".
Crocodile
Hancock
Past:
None.
Reasons he can join: Saved Ace from death
Has a secret which has a connection with mister Ivankov.
Reasons he can't join: The whole Arabasta affair.
Silver Medalist.
Own Opinion
Not much known for him to be a nakama. BUT! I think he can be one. Why?
The whole secret… I think Crocodile was female before. Which could be a whole turnover.
