"Think about how Galatus changed from living armageddon to cosmic b!tch."

Now THAT'S just straight up unfair to one of the highest degrees. I usually see it that way for the Silver Surfer more.

But I mostly mean circumstantial nerfing to give the main character a means to beat the opposition by exploiting a weakness or giving the antagonist a reason why he cannot go all out (can only knock out but not kill the protagonist, exhausted strength on other powerful opponents or an entire city before the protagonist shows up, succumbing to the secondhand effects of a power-up, suffering from a sickness) and pull it off in a sensible way which has been done a few times. This way, it gives the antagonist credit because the hero had to win while the bad guy had a disadvantage and it furthers the plot.
