Water 7 Arc
After the Straw Hats arrived at Water 7, the Franky Family mugged Usopp and stole 200,000,000 beli from him. When Usopp entered their house to take the money back, the Franky Family beat him up and threw him out. Moments later, they fought against Luffy, Zoro, Sanji, and Chopper. Kop and the other Franky Family members were badly beaten. After Franky abducts Usopp later that night, the Franky Family tried to lure out the Straw Hats but caught the attention of CP9. CP9 then beat up Kop and the others before heading to Franky's hideout where they abducted Franky and Usopp. After CP9 left Water 7, Kop and the others turn to the Straw Hats for help.
