Biske must not be on yet becuase we no where his list would start and end. With that said I will drop mine.
1. Mario/Wario/Twista, more for his "sportmanship" than pure skill
2. Superken, he kicks my A** everytime we run into each other
3. K A Z, I have never seen anyone mow throw people like my Japanese friend
4. Crow, really this one should be Clifford, but we have to put his master on here.
5. BISKE, I will give him his props, I'm yet to drop him one on one. but he could say the same for me.
Take this list with a grain of salt, I dont sit around Yew gate like some. So I dont have much experience dueling non guild members. However I field fight either with or against these guys almost everyday so there it is, the 5 chars you dont want to run into trying to do a rats solo
