Minato just being too fast isn't good enough??? i feel offended lol jk but yu may have a point but seeing as how it's Minato & his ability to yu his Time space Jutsu with incedibly accuracy, i think he'd be able to avoid being caught in a Genjutsu, now if he got stuck in a Genjutsu then thats...
can't be the 4th Mizukage cuz Obito easily put him in a Genjutsu & claimed the title as the "real" Mizukage & also can't be Kabuto cuz Itachi already put him in a Genjutsu called Izanami, the sister Genjutsu of Izanagi
1.Madara-Would be able to due to His Eternal Mangekyo sharingan
2. Obito(Tobi)- also him cuz of his sharingan along with His rinnegan & Harishima's Cells
3.Minato- Just too fast....
