Minato has like 3 tech Rasengan, FTG, and RDS not really hard to beat. ]
Here comes the logic.
Minato throws Kunai with FTG seals. Itachi Katon jutsu burns seals off Kunai. Minato cant teleport like the bitchh he is and gets owned.
Lmao second time I've seen that fail argument. If it was as easy as just burning his seals he wouldn't have been considered so powerful. Not only that but Minato always had seals placed in and around the battlefield. It would be impossible for his opponent to simply locate all of them and burn them.
What makes you think that Minato wouldn't be able to FTG to a kunai, take it, and FTG to another one before said fire user could burn the seal off anyway? He could probably do that easily. He's more than fast enough to get it before any regular fire jutsu hits it. Only amaterasu would be fast enough, and good luck using amaterasu numerous times to burn all of the seals, lol
Read the manga bro, Raikage said that he didn't think anyone would ever be able to surpass minato.
As for the most overrated im going to have to say Itachi and Hiruzen. Itachi because it's common for me to see people arguing he could beat Nagato/6 paths of pain which is just retarded, and Hiruzen because all we've seen is old man Hiruzen which was impressive but not that amazing, and we've never seen the mystical "prime Hiruzen" everyone talks about
I see Kisame overrated quite often as well, mostly just by Kisame fanboys.
