Scar <== sword <== Zorro <== you are all wrong.
what does Mugiwara mean ?
Obvious troll is obvious...
Bullets also leave scars. This is Ussop's enemy.
I hope Sogeking comes back to help him, though.
it wasn't a troll
Since when has Usopp made any enemies? His entire childhood was spent in his home village, and he hasn't "ruined" any one's life while with the Strawhats.
Sogeking's enemy then, he is badass enough to have strong enemies.
Maybe it's Franky? I'm putting a bet o Zoro though, Oda is quite predictable.
It could also be Sanji's, since Sanji does use knives
