Post-Climax Confrontation

""There's a couple of things they don't teach you at Harvard Business School. One is how to cope with defeat, the other's how to handle a shotgun. I'm going to do both right now.""

- Russ Cargill, The Simpsons Movie

As an audience, we expect a story to be played out in a certain order: Exposition, Rising Action, climax, falling action, and Denouement. In many stories, the climax also serves as the Final Battle. The events that occur afterward are normally devoid of action, serving to tie up any loose ends and create a satisfying ending.

But sometimes, writers like to throw in one last confrontation. Perhaps The Dragon assaults the heroes in one last attempt to kill them, or the Big Bad has a final form that took a while to set up. No matter how it occurs, our heroes will have to battle one more time before the day is saved.

A particularly extreme version of Your Princess Is in Another Castle that occurs just when the plot seems ready to be over. To be a Post Climax Confrontation, the event must follow some criteria:
 * The major threat of the day MUST be resolved. The Big Bad is defeated (or there's at least no sign that he survived), there's no sign of The Man Behind the Man, no army waiting outside to defeat the heroes. Examples of this trope are rarely the Big Bad (though both of the Alien examples are exceptions) and are typically an independent force.
 * This conflict must be settled within the same installment of the story. If the event results in a new conflict told within a different installment (or just ends as a Cliff Hanger), it does not count.
 * This is the crucial part: there must be closure. Plot threads and character arcs are being tied up. In stories that have a traveling party of characters, the party has begun to split off, returning to their homelands. The Post Climax Confrontation in these kinds of stories generally happen to a select few of those characters, rather than the whole group.
 * As this is a twist trope, the final confrontation must be sudden and unexpected. The antagonist being confronted in question may or may not have had foreshadowing that he/she would be confronted. It is when the conflict occurs that's surprising: as the plot and character threads are being tied up.
 * Finally, this is a final confrontation: there are no more conflicts after this threat has been taken care of.

A subtrope is Dragon Their Feet, when The Dragon from earlier in the Sorting Algorithm of Evil returns unexpectedly for another go.

Naturally, all of these examples are major spoilers.

Anime and Manga

 * An 80's (or before) anime version of Jack and the Beanstalk greatly expanded the story, having Jack rescue a princess and fight a Maleficent-like evil witch who had taken over the kingdom in the sky. The good guys prevail and the evil witch is vanquished. All seems well, until her giant son Tulip shows up and chases Jack. Jack is forced to climb down the beanstalk with Tulip in pursuit, and chop it down while Tulip's still climbing after him -- thus cutting off access to the kingdom in the sky and the princess.
 * In Twentieth Century Boys, this is what the majority of the last two volumes (titled 21st Century Boys) is based around.
 * In the final episode of Mobile Suit Gundam 00 Season 1,
 * The last episode of S-Cry-ed takes place after the defeat of the Big Bad, as the heroes tie up some minor side conflicts, then they square off to determine once and for all which of them is the toughest fighter.
 * In Patlabor The Movie, the main characters succeed in dismantling the Ark (which they are in too) into the ocean before the typhoon hits it, and the crisis seems to be over.
 * In Rurouni Kenshin (manga only), Kenshin explains to Saito that, due to one thing and another, his body is rapidly deteriorating and soon he won't be able to fight anymore. Thus he offers Saito a duel to settle things once and for all, to put to rest the ghost of their bitter past. Saito declines, stating that Kenshin is no longer the man he wanted to defeat. It's as much bittersweet as it's heartwarming.

Film - Animated

 * In The Incredibles, the family defeats Syndrome and they are heading home; when they arrive, they find out that Syndrome has abducted their youngest son Jack-Jack, so they must rescue him and defeat Syndrome again.
 * The Simpsons Movie, when Springfield has been saved and everything seems to be fine again, Russ Cargill comes out of nowhere with a shotgun and attempts to kill Homer and Bart.
 * In the fifth Dragon Ball Z film, Cooler and his henchmen have been defeated, and the worn-out heroes relax and laugh--when Cooler's Dragon, Salza, re-emerges, Not Quite Dead. He tries to finish the weary heroes off but is defeated by Piccolo.

Film - Live Action

 * Die Hard: Karl manages to survive being strangled (!), and attempts to kill John McClane one last time after Hans Gruber is killed, but is quickly shot before he can do anything.
 * The botched execution of Jack Sparrow (and his subsequent escape) in Pirates of the Caribbean: The Curse Of The Black Pearl occur after Barbossa is killed.
 * In Air Force One, after killing lead terrorist Ivan Korshunov, retaking the plane, and fending off Mi Gs on an intercept course towards them, The Mole attempts to kill President Marshall as he's about to evacuate the plane before it crashes.
 * The final confrontation between Ripley and the Xenomorph in Alien and the Xenomorph Queen in Aliens definitely qualify. Both occur after the protagonists appear to have escaped.
 * The last scene of Disney's The Three Musketeers 1993. After the heroes defeat Cardinal Richelieu and Rochefort and save the King and Queen, they're confronted by a group of thugs who started pursuing D'Artagnan at the beginning of the movie. It's been so long since the audience saw them that their appearance is a surprise.
 * Used regularly in James Bond movies:
 * From Russia with Love: After defeating Red Grant and supposedly home free, Rosa Klebb turns up for some shoe fighting action and forces the Bond Girl to decide where her loyalties lie.
 * On Her Majesty's Secret Service: Tragically used; after the wedding, Blofeld and his henchman kill the new Mrs. Bond in a drive by shooting.
 * Diamonds Are Forever: After defeating Blofeld's schemes, My Wint and Mr Kidd turn up for a "Bombe Surprise".
 * Live and Let Die: The Dragon TeeHee attacks Bond in the train.
 * The Man with the Golden Gun: Nick-Nack tried to attack Bond on the junk after he's defeated Scaramangar... like he had any chance.
 * The Spy Who Loved Me: For a moment it looks like Triple X is pulling one of these on Bond, but she changed her mind about killing him once the mission is over -- she wants to shag him instead.
 * Tomorrow Never Dies: After Bond kills Carver, Stamper shows up with Wai Lin as his hostage and tries to drown her and finish him off. Bond traps him in the missile firing mechanism and leaves him to die while he saves her.
 * Casino Royale: Just when you think that Bond is going to retire with Vesper, she pulls a Face Heel Turn and sets up the final act.
 * In this case though, that was less of a Post Climax Confrontation and more a case of a climax coming later than expected.
 * Evil Dead: Hail to the king, baby.
 * In Hot Fuzz, after the final, massive shootout against the NWA and the defeat of Devil in Plain Sight Simon Skinner and the Big Bad Police Chief, everything seems like it's all wrapped up and the cops are all finishing up their paperwork, when suddenly the one NWA member they forgot about bursts into the police station and starts shooting.
 * The penultimate scene in Serenity is a variation in which nothing actually comes of the confrontation. Having been spared by Mal in their earlier confrontation and subsequently ordered his men to provide medical attention for Mal and his crew, The Operative concedes defeat and walks away; he only kills for his cause, which is now lost. Mal tells him that if he ever sees him again, he might kill him. The Operative replies "you won't".

Literature

 * The Lord of the Rings may be the most well-known example. The One Ring has been cast into the fires of Mordor, our heroes have gone their separate ways, and the hobbits are ready to return to their peaceful Shire... only to find that it has been taken over by Saruman, and they must take back their home from the evil Men that have enslaved their people. It was omitted from the Peter Jackson films, though the omission didn't stop some filmgoers from experiencing Ending Fatigue anyway.
 * Both the book and movie Coraline have a perfect example, after freeing her parents, the souls of the ghost children, and escaping from the Other Mother's monstrous form and custom dimension, Coraline is attacked by the Other Mother's hand, and has a comparatively easy fight against it.
 * In Dragon Flight, after the big bad is dead, the dragons are freed, the war is over, our heroes return home.. only to learn that Dragons have been banished from the kingdom. this leads to quite a bit of shouting, and the interruption of a royal wedding.
 * And again in Dragon Spear, after Darrym is defeated, Velika is rescued and all seems well..... the baby dragon princess is snatched....

Theatre

 * A heroic version of this occurs in the ending of the Wicked musical;

Video Games

 * Baten Kaitos has perhaps the most bizarre example. Xelha and Kalas go off into the Moonguile Forest in order for  when suddenly
 * Mega Man X Command Mission pulls a rather sudden one. The Rebellion and its leader Epsilon have been defeated, X and the others are lauded as heroes, and X, Zero, & Axl are prepared to take an airlift back to their home. Story's over, right?
 * Depending on your interpretation of events, the last sequence of Killer 7,, can easily fit this trope.
 * Occurs at least twice in Metal Gear. In 2,  In Solid,
 * And in Metal Gear Solid 4 Guns of the Patriots, the final battle with Liquid Ocelot happens after
 * The twist ending at Pokémon Red and Blue is so famous, it's practically a It Was His Sled. After fighting your way through the Elite Four, your character and his exhausted pokemon are informed that they're the new champions!
 * In the main games the Big Bad is usually defeated after getting the 7th gym badge. Except in Red and Blue where the Big Bad is the 8th gym leader. You still have the Elite Four and Champion after that though.
 * Science Girls! pulls this one after our heroines have seemingly prevented the invasion, escaped the alien homeworld via wormhole and destroyed the transporter to Earth.
 * Really more of a Your Princess Is in Another Castle to anyone who plays JRPGs, as there obviously hadn't been a Big Bad Boss Fight yet.
 * At the end of Wild Arms 1,, the efforts to drain Filgaia's life have been thwarted, and there's a good chance that its decay will even be reversed. The party takes the teleporter back to the earth.
 * Mario & Luigi: Partners in Time ends with the Shroob leader  defeated, their invasion thwarted, and their race wiped out.
 * Suikoden IV has . Leads to an Alas, Poor Villain moment afterwards, as it's noted that they had no real reason to sacrifice their life.
 * Sometimes employed in Metroid games. Specifically,
 * In the Game Gear game Legend of Illusion Starring Mickey Mouse, Mickey defeats the Big Bad, restores everything, plays a Bonus Stage, and returns to his home kingdom... but then King Pete (who wasn't heard from since the game's first level was completed) shows up and a boss battle commences.
 * In Onimusha 3, sneaks up on Leon and his family after everything seems to be resolved.
 * In No More Heroes, the "Real Ending" leads to the long-awaited confrontation between Travis and Henry, despite the original conflict of the assassin rankings having been resolved in the previous fight.
 * Final Fantasy VII: Advent Children. Just after the Big Bad is defeated, Yazoo and Loz show up to harass Cloud, trying to take him with them, either for revenge or because they want their "brother" to go with them (they're kind of childish). It doesn't end up being so much a fight as an explosion.
 * In Dragon Quest Monsters Joker 2, the game itself takes place on an island you crashed on trying to get to a tournament. Once you beat the boss of the island/final boss of the game, you leave and go to the tournament, which is so incredibly easy and postscript-ish that it's mostly done offscreen save for the (still easy) final battle of it.
 * In Fallout: New Vegas, after defeating Legate Lanius in the final battle in one way or another, the game is pretty much over. However, if the player takes the Mr. House or the Wild Card path they will then have to deal with the General Oliver and the NCR, who will not accept Vegas as an independent city-state. You'll then have to convince them in some way, or just kill them all.
 * The entire Awakening Expansion Pack for Dragon Age Origins: the Archdemon has been defeated, the Blight is quelled, the Darkspawn are slowly retreating back underground... well, the latter not quite. Turns out, there is one loose end to the Fifth Blight, which needs to cleaned up before the Thaw and rebuilding can settle in.
 * In the ending of The Witcher 2 Assassins of Kings, after defeating and resolving the political conflicts of the game, Geralt gets a message from Letho to have a meeting. At this point, Letho provides exposition for his part in the story, after which Geralt has two choices: A duel to the death or just letting the man go on his way.

Real Life

 * One could argue that the assassination of President Lincoln and subsequent pursuit of John Wilkes Booth at the end of the American Civil War was an example of this.
