Yondaime Hokage

As Hokage, Minato was a extremely powerful shinobi compared to most ninja.His skills were so advanced he could fight both A and Killer B on multiple occasions, each time defeating them or driving them off. A remarked that he found it hard to believe anyone could surpass Minato even years later, and B even expressed chills when he remembered Minato. During the Nine-Tails' attack on Konoha, Tobi believed Minato was the only one capable of interfering with his plans, and indeed, it was only through Minato's actions that the attack was ended and the village saved from complete destruction. When the Konoha Crush loomed years later, Minato was believed to be the only one who could have stopped the threat Orochimaru posed to Konoha, and for that reason, his death was deeply regretted.
