I don’t know if it’s the ease with which Saitama became a hero, his genuine humility, or the fact that he tears through the hero ranking system like gangbusters is what upsets the other heroes, but his presence inspires big feelings in the people who meet him. Some are happy to work with him and see his value, and one, a cyborg named Genos, even becomes his disciple. Others are determined to take him down a peg. Right off the bat, as they’re wrapping up Saitama and Genos’ orientation to the Hero Association, Snakebite Snek wants to put Saitama in his place. It backfires, of course, because Saitama is ridiculously strong, but Snek makes it his business to cause him trouble.
