I just remember them saying that there were a few proto 01s that started talking after the invasion of the B-Crystal, Sumuru's dad also said that the reason for the Proto 01's talking was because of dragolds power was dispursed. I also remebering this one kid's Proto 01 light come out of it go into Dragold. It didn't say anything but it's owner was asking it if something was wrong cause it wasn't answering him back so I assumed that his Proto 01 could talk.
