Some possible reasons for a Post-Climax Confrontation occuring within a given work include:
- A given antagonistic character who's actually currently still alive and well hasn't actually been seen for quite some time needs to have his/her story wrapped up before the work's true ending sequence, so the writers throw in a sequence where in which the lead protagonist of the given work battles him/her to the death one final time in order to be able to have that part of the central conflict resolved at the last minute.
- Everybody in this world knows that it's generally considered to be perfectly standard procedure for the portion of a given work that follows its climax to be entirely devoid of any more significant action sequences, so the writers throw in one last action sequence that serves as the work's true final battle of all things just to properly subvert the audience's expectations one final time before the work's true ending sequence.
- Sometimes, an example of this trope's occurance within a given work may not have anything at all to do with its main plot and therefore instead serves as a means of finally tying up a sub-plot within the work that would otherwise create an Aborted Arc and also significant Headscratchers for audiences along with that.
- At first glance, the very occurance of this trope within a given work may appear to be an Ass Pull that solely exists just to put one final action sequence into the story, but this trope's usage can still be effectively foreshadowed earlier within the work since the antagonist being confronted in question may or may not be a Plot-Irrelevant Villain, and plus, the exact time gap between an event that essentially foreshadows a future event within a given work and the actually foreshadowed future event can vastly vary depending on literally any number of potential factors.
- Examples of this trope are literally always the final confrontations to be found within given works because once the audience is surprised with this trope's occurance in the first place, it completely takes away from the surprise factor of it happening again at a later time.
- Even if a given antagonistic character appears during a given work's climax but doesn't explicitly die off during it, then the usage of this trope can allow them to surprisingly appear again one final time so that the main protagonist can have another chance at being able to finally kill them off for real this time around.
- An additional key factor that can sometimes make this trope's usage especially effective is whenever its very occurance in the first place perfectly plays into the previously established rules and parameters of a given work's storytelling technique, easily making for a moment that would otherwise be anti-climatic if it actually weren't to happen at all ironically enough.
- Examples of this trope are not always ones of violence as they can sometimes be examples of verbal battles of wills fought in between certain characters of a given work, or they can even happen as a result of somebody trying to retrieve a stolen item from somebody else.
