I’m rather surprised that he can regenerate like piccolo. Piccolo and Cell could because their body is meant to be able to do it, moro isn’t supposed to. I know it may be something like cellular multiplication so moro could do it, but if it’s the case, it looks like anyone could learn it without having namekian cells. Imagine if Moro turns super saiyan without having saiyan DNA, it doesn’t even sound right. I hoped to see Piccolo unfuse with Nail and maybe Kami after Moro’s attacks also.
