I like both male and female Buggy. I'm much more interested in women then men, but... Buggy's just too cute and funny either way. I love how much he loves Shanks, but will never admit it. Also, it's fun to see Buggy unknowingly helping the guy who inherited Captain Roger's Will. I think Buggy has come to like Luffy, though he'll never admit that, either.
Can't wait for Cross Guild to make their flashy entrance!
