Fukurojo who is Raizo rival (Raizo did to Kaido what Ussop can't dream doing to him) is a fodder. Well
Firstly Usopp killing Kaido
Secondly Hyogoro and the others have more ties to the ninja
Thirdly I didn’t mean fodder in the literal I meant that they are not important whatsoever
Fourthly it was stated that he was raizo’s rival as a ninja not in power.
Fifthly Oda doesn’t care about power scaling
Sixthly these people are such fodder that didn’t even mention their names in the main story he only mentioned it in an SBS
