@Aniki:
I mean Jesus Christ most of the time they are crossing there arms, sitting, doing a chore (that anyone could do), eating or standing around doing fuck all anyone could be in the color spread…and I cant believe so many people are going off at this.....WHO CARES about the god damn color spread. Its the fucking story I'm concerned about
It's simple: people will try to say anything to 'prove' they are right.
Strangely enough, I don't think she will join, but have been playing devil's advocate here and pointing out reasons why she would be a nice addition to the crew, just because a lot of arguments against her make no sense. In the end, someone wants her to join or not based only on personal opinion, there's no 'logic' or 'reason' behind it.
A lot of past characters could have joined: Pell, Wiper, Paulie, Vivi. A lot of past characters seemed like they would never join, but did: Usopp, Robin, Franky (at first)… In my mind, someone joining has more to do with what Oda plans to do with him/her, than what the character was doing before he/she joined the crew.
I mean, let's roll back in time and imagine we discussing if Usopp would join or not. People would be saying things like: "He's not strong", "He has a generic dream", "His hair is black, like Luffy's", "His cowardice will be boring and repetitive".
Now Robin: "Her Devil Fruit's too powerful", "She has black hair like Luffy and Usopp", "She's a villain", "She's too quiet and won't interact well with the others", "She has no function in the crew", "Luffy is not interested in her", "Luffy does not like her", "Luffy will never ask her to join".
And Franky: "He's beaten Usopp and stole the crew", "No one on the crew likes him", "He's too weird", "He's too old to join", "His dream don't require him to go with the crew", "Luffy hates him".
In my opinion, it would actually be fun to have Hancock around. She has a strong personality and her interactions with the crew would be funny. It would be cool to see her kicking Chopper or petrifying Sanji, or bonding with Nami and Robin and at the same time being jealous of them near Luffy, or ordering the others around and being contested. Also, she has that snake pet, and I bet she has an interesting Haki-using fight style. I think she uses the snake as a bow, like Marguerite, or maybe as another weapon (hmmm... whip?)
I see her kinda like Emma Frost of the X-Men, the former Qhite Queen of the Hellfire Club. She bitches around and try to llok "better" than anyone else, but cares about the team and is in love with the leader, Cyclops. She eventually warmed to the others and let down her jerkmask a little.
The only reason I think she won't join is because her narrative role in the story will be other. She's not meant to join, she has some other part to play in the story, like Vivi or Cobra or Iceburg. But I could be wrong, and would be pleasantly surprised if she joined.
