Uhmmm, I hope you know too that in other timeline, he didn't have nano and still became the head of the cult and was powerful :3 His descendants wished for him to be stronger than he was so he gave him nano :3 So uhm yea, he is stronger with nano, but even without nano, he's still strong. So he's not exactly, "nothing" :3
