And then you end up with contrived plot points like kryptonite.

Or the alternative: plot armor so thick people even get brought back from the dead regularly.

In One Punch man the gag is that while everyone is fighting for their lives, Saitama is usually distracted by other priorities that are often trivial (such as getting some bug spray, or saving some money down the local convenience shop as they have a sale on noodles), he also rarely gets the recognised for saving the day once he does bother so show up.
