Talk:Mirajane Strauss VS Seras Victoria/@comment-26826501-20161030185926/@comment-26826501-20161030222430

From the Fairy Tail Wiki: " Macro allows the user to take total control of something, which is defined as giving an "order." [4] Whether they are dead, [5] alive, [6]  or an inanimate object [7]  is irrelevant; though it has been noted that corpses do not function as well as living bodies. [8]"

So far, only Mirajane has shown immunity to it due to the nature of Satan Soul. If there are limits, it's usually very specific. It probably wouldn't work on Gray as he is immune to all Curses, it won't work on Acno because he can't be controlled period, and it won't work on Zeref because he's Zeref.

I'm sure there are limits but literally the only limits we've seen so far are it being less effective when used against multiple people and when used on corpses. And because Mirajane hasn't used it on anyone else despite certainly being able to, I get the feeling that her not using it is plot-induced. And it's not just for Mirajane either. Remember Bloodman? He had Macro and he could've easily used it on Sabertooth as well as Levy and have them kill each other (while having Levy attack Gajeel) but he didn't because then there wouldn't be a plot.
