Types of PiratesEdit
A peace main is a pirate who goes on adventures and doesn't really care about amassing treasure or fighting other pirates. That is not to say that they will not steal treasure from others if it is there and the chance is open, but their primary goal is usually not to own it and greed is generally not their motivation. More often than not, a peace main pirate sees his or her own crew as their most valuable treasure.
The morganeer fight for treasue and personal gain. They are greedy and love to fight just to cause other people pain and misery. The peace main pirates however, only steal from them, so it is safe to say that the relations between the two aren't the best.
Morganeer pirates don't see their crew as a valuable asset to them and will easily kill them for opposing them. Also, many of the morganeer type pirates don't dream at all, and if they do, it is about achieving world domination or something along the lines of that.
Hierachy of the SeasEdit
The Four BluesEdit
Generally outside of the Grand Line, most pirates operating in the blues are considerably weaker than those inside. Often, they are left untouched by the Marines because their attention is drawn towards the Grand Line rather then the East, West, North, or South Blue oceans.
That is not to say that they do not have their share of villainous pirates. Generally, few people in the four blues have access to Devil Fruit or general knowledge of them.
The Grand LineEdit
While there are individual pirate crews roaming the Grand Line, the more powerful pirates reside in this sea. These are namely the Shichibukai and the Yonko.
Generally, the weaker pirates are often weeded out by the Marines or Shichibukai before they can get any further. The unfortunate ones don't even make it to their first island due to a lack of understanding on how the weather works on the Grand Line. The Grand Line is where you're most likely to see Devil Fruit users, both in and out of pirate crews.
In the second half of the Grand Line the most powerful pirates are the Yonko. The second half of the Grand Line is their playground and it forms a rather dangerously balanced part of the One Piece world.
Due to the Red Line, the Grand Line is separated into two segments. The first half is known as Paradise where the second half is called New World.
