If Kaido has a fruit it may be tied to the type of army he has established, animals. Maybe he has an ability, similar to what was seen by Orlumbus, to command animals. There is no sign that Orlumbus' ability is fruit based, but it is possible Kaido wanted zoan users only so that he could have a special control power upon all of them.
