i made this thread because there some ppl who said that sasuke didnt worked hard to get all his power especially MS/EMS powers. that not true sasuke earned the MS the moment he heard the truth about itachi and realized how important he is to his life... now what itachi did gave to sasuke is the ability to use amaterasu.. no not all the time he gave him that eye power in order that it will automatically used when obito will try to get close to sasuke (one time thing). sasuke learned it in his fight against bee i guess you earn an MS jutsu exactly the way you get the regular sharingan: in a " bad time" means where you are in a bad situation when you might lose your life... (remember how he got MS genjutsu? bee almost raped him with his biju cloack and how he got amaterassu? when he almost died by full 8 tails). susano is a bit different story you get it when you achive both of those jutsu and you can evolve it by emotional... i guess that y sasuke susano was purple and itachi was red.
