What level the vinsemok family are?
You want a number or a group equivalent? I can tell you now they are no where close to admiral or yonko level :P
They are strong enough to rule. They once ruled North Blue with an iron first. We already know some of their abilities but we still don't know much of their full strength so we can't be too sure. As of now, probably below the Yonko level.
Pokemon wiki that way >
What do you think?
