All throughout comics, and other fictional mediums but especially comics, we've seen heroes have trouble against certain villains simply because they conveniently forget that they have a power that would allow them to end a fight in an instant or that is a hard counter to said villain and/or only remember it at the end of the fight when they're already on the ropes. However, I do know that this happens so that the story lasts more than one page or, in some cases, one panel, so it's clear that this is due to plot. However, this tends to happen a lot, especially with long-running heroes, especially in comics, so much so that it can make one wonder, especially a versus debater, whether or not the character is just that stupid, for lack of a better term, as well since it could affect the result of some debates. An example of this would be where the Flash, given his abilities, should win a fight in one panel against an opponent who is at or barely above Peak-human speed, reaction time, and reflexes, but since Flash has had trouble and actually been beaten by guys like this, such as Slade Wilson in comics, that an opponent that doesn't BS around and would go straight for the incapacitation or kill would beat him since he might not go all out until he realizes the threat and by then, it would be too late.

So, when does Plot Induced Stupidity become Character Induced Stupidity for the purposes of a versus debate?
