Ohh I had forgotten about the chakra sensory thing, I might edit it in there. (Credit you of course)also remember that the black zetsu seems to be the ultimate sensor ninja. the instant B and Naruto broke trough the island barriers he noticed it, and it looks like he isn't that close to them either.
also I noticed that when black zetsu senced this and he wanted to warn madara about this development a white zetsu poped up at madara's location giving him the intel the black zetsu had gatherd. because of this reason I do think that the black zetsu is the original and the white zetsu's are a byproduct of on of his jutsu. another indication of that is that at the kage confrence when all the white zetsu's pop up from everybody to suck theyr chakra it's the black zetsu that gives mention of using his "hoshi no jutsu" tech, not the white one that was given to sasuke to show him the way to the confrence
and when it comes to black zetsu escaping the mizkage's acid mist attack, remember that zetsu can travel through materials, through earth and stone (proven at the 5 kage confrence) so traping zetsu is not going to be that easy.
as far as attack power we have not yet seen many great things from black zetsu, only straigh forward offences on the feudal lords, but he could be holding lots up his sleave, we just have to wait and see
@Legolass: Isn't the point of making a thread to get attention for yourself and to start a discussion? And quit spamming up my thread with your triple posts. -.-
