Similar to my Amatseru question, could Kumai somehow incapacitate Logia type Devil fruits?
Ex. Kumai akainu's head off what would happen? Would he regrow the head? Would he be unable to move? Or would his head grow a new body?
It will still reform, the head in the dimension will be just the element the Logia are (not their real head)
It won't weaken them, it seem like Logia can replace their lost mass if they are not attack by Haki or by Law's power
