User blog comment:OnePieceNation/Which of these series wouldn't you mind getting a crossover with Hunter X Hunter/@comment-269409-20130701214337/@comment-5314364-20130703032457

^THIS 1000 TIMES!!!

Hisoka vs DIO

Pucci vs Chrollo

Knuckle vs. Josuke

Palm vs Yukako

TO MANY POSSIBLITIES!!!

Plus apparently Togashi 's friends with Araki,Oda,   and Shimabukuro. So I say those 3 have the best chance.

I think YYH already had one though. It was was more of a cameo but Yusuke appeared in a 4 panel New Years  omake with Kurapika,Saiyo and Pufu.
