Hero Ball

Everything About Fiction You Never Wanted to Know.
"Now you see that Evil will always triumph, because Good Is Dumb."

It's the third act, and Brent McHeroman has Doctor Klaus Von Puppykicker disarmed and backed into the corner. And Brent is... giving Klaus a stern warning. Didn't Klaus kill Brent's girlfriend and carpet-bomb his hometown? Wasn't he threatening to nuke the Throwaway Country thirty seconds ago? Why won't Brent just Kill Him Already?

Oh, that's right, he's holding the Hero Ball.

This is the hero-specific form of the Idiot Ball, which causes its holder to make downright moronic decisions solely because the plot demands it. Unlike the Villain Ball, the Hero Ball almost never leads to its holder's permanent defeat; it merely delays the hero's inevitable victory, ratcheting up the dramatic tension in the meantime (at least, until the Fridge Logic kicks in). Of course, once victory is assured, the Hero Ball will prevent its holder from killing or permanently incapacitating the villain—after all, the villain needs to be back on his feet in time for the next episode.

If he carries the Hero Ball long enough, one almost gets the impression that the hero is more interested in padding the plot than in actually defeating the Big Bad. This can be particularly frustrating when we've been shown (or at least told) that the hero should be smarter than this.

Heroes who are likely to carry the Hero Ball:

Plot and devices resulting from the Hero Ball:

Note that some of these tropes are mutually contradictory; for example, a Lawful Stupid character carries the Hero Ball all the time, but would sooner die than Save the Villain. Apparently, there's only so many ways to be smart, but idiocy is Legion.

Modern, Western action movies usually combine the Hero Ball with some form of Karmic Death. The hero can't actually be shown executing the villain, but that doesn't mean the villain can't fall to his death, be eaten by his own monster, crushed by his own machine, fall into nearby acid or lava, or impale himself on some nearby sharp object, or be otherwise Hoist by His Own Petard.

Compare with the Villain Ball and Holding Back the Phlebotinum. Contrast Flaw Exploitation for when an antagonist exploits a heroes' flaws. Contrast No-Nonsense Nemesis, who isn't prone to carrying the Villain Ball.
