I think your all overeacting about SM minato..yes it is an ass pull..yes it is something that kishi thought of at the spur of the moment...all this is obvious it was never intended for minato to have SM from the very beginning i know that so every one should stop trying to explain it...but i for one always wished since SM was introduced that minato had it....because with SM it finally makes him the geniuse he was intended to be i was dissapointed that he was only given ftg and rasengan at a point because i wondered how can the hype be true that he was supposed to be the savior that he was one of the most powerful characters and with SM its true..we all know the power of sage mode and how powerful it makes you....if you want to argue ob the side of this not being an ass pull theres not much you can say...he could of used it again juubito but kishi had not thought to give him that power...though you can say he did not need to use it during the ninetails attack..he beat obito pretty easy with out it...i think his death against the ninetails was more so he would not have to live with out kushina then him not being able to stop the nine tails...he could of usdd it during the 3rd war...maybe just not in any of the flash backs it seemed he hsd everything under control with out it....aside from all of that its an obvious ass pull...a good one though not like he beat madara with it
