Actually, it kinda is.
If the author can't pick a single animal to represent a character, and needs to resort to multiple animals depending on what he's feeling that day, just to create some mid tier parallels so people can think he's some "genius", then yeah, I have a problem.
Oh yay, I wonder what third animals are gonna represent each straw hat.
Can't wait until each of them have an entire zodiac of animals representing them.
F-U-N.
When Zoro fights Mihawk, which animal is he gonna be?

My money is on "Crow" because black bird = black blade.
