History Recap / SamuraiJackS5E10CI

* EurekaMoment: When Jack says that Ashi has Aku's powers, she gets the idea to take Jack back to the past, the same way Aku sent him forward to the future.

** Changing the past has great consequences (both negative and positive), as Jack witnesses for himself.
** Past-Aku sent Jack to the future in the first place so his stronger future self who already won and had more experience could kill him, and Jack now has 50 years more experience than he did when they first fought, in addition to arriving immediately after he nearly defeated Aku the first time meaning the demon isn't at 100%. As such, Jack simply cuts Aku to ribbons and destroys him with zero effort.

* KilledOffForReal: Jack manages to travel back to the past and finally deafeats Aku, who explodes into nothingness.

* FamousLastWords:
** Both the past and future versions of Aku have one last line before Jack puts an end to his reign. The future gives a horrified "[[LittleNo oh no]]" while the past shouts "No, wait!"
** Before fading away from existence, Ashi's line shown above in the recap is the last thing she ever says to Jack.

* SurprisinglyRealisticOutcom:

--->'''Aku''': "You're back already?!"

* PreMortemOneLiner: After returning to the past, Jack yells "No... more!" before he unleashes the killing blow on Aku.

* RealityEnsues:
** Even though Aku is more or less immortal, hitting him in the eyes will still have a bit of an effect on him.
** Changing the past has great consequences (both negative and positive), as Jack witnesses for himself.

** All of the memorable, quirky, endearing characters Jack has met through his travels [[YouAreNotAlone come to his aid during his darkest hour]]. [[WarIsHell Too bad the vast majority of them get ruthlessly butchered.]] Apparently, if you pick a fight with an EldritchAbomination who conquered the world all by himself, you're nothing more than a distraction at best. On the other hand, there ''is'' a limit on how long a CrapsackWorld /BadFuture /VillainWorld can last and people could no longer tolerate it.

* EarnYourHappyEnding: After being trapped in the future for 50 years, Jack is finally back in the past and Aku is dead. Although he has struggled greatly and had to sacrifice many things, including Ashi when she [[RetGone disappears]], he has freed the world from the UltimateEvil; and it now has a chance to grow up in a more peaceful future, [[BittersweetEnding and Jack can finally live a normal life and move on from his struggles]].

* EurekaMoment: When Jack says that Ashi has Aku's powers, she gets the idea to take Jack back in time so he can defeat Aku there.

** For some reason, Jack's parents, while technically elderly by the time Jack returned to his homeland to face Aku, are depicted as they looked when Jack was 8.

* OpeningShoutOut: Aku's broadcast begins with the original series' opening sequence.

-->'''The Scotsman''': ''*beat*'' I don't think she's yer type, laddie.

* ThemeTuneCameo: Aku broadcasts the original theme (minus the will.i.am song) for all the BigDamnHeroes to see before he executes Jack. Instead of having Greg Baldwin take over for the narration, Mako's original recording is used.

'''Man-Ape''' No, jump good!

-->'''Ashi:''' Without Aku...I would never have existed.

* MauveShirt: Characters who survived their debut episodes and original one-off appearances die in the finale, most notably the Andromeda robots from "Jack versus Mondo Bot," who are absolutely obliterated on-screen.

** Past-Aku meets his demise when Jack returns from the future... and because Aku cast him there in the ''first place'', Jack is now so much stronger while he's still injured from past!Jack's fight and so easily annihilates him. In addition, Aku died the same way he loved to kill others: facing a being who outclassed him to such a degree that any meaningful offense is impossible and dying as terrified as his victims often were.

* EmbeddedPrecursor: The episode partakes in some episode-ception by showing the original opening in it's slightly-altered, yet still faithful glory.

* RagtagBunchOfMisfits: The army assaulting Aku's tower could not be more diverse. While the Scotsman's clan and the Spartans are trained and skilled soldiers, most are simply allies of Jack under Aku's rule with nothing to lose, including [[BadassPacifist Monkey-Boy's tribe]], the [[FreeRangeChildren Rave kids]], the [[PettingZooPeople dog archaeologists]], [[HandicappedBadass the Archers]], and [[FishPeople the Triceraquins]], with [[HumongousMecha the ancient Robo-Samurai]] thrown in for good measure.

** Once he realizes that Ashi has his time-portal powers and has handed the sword to Jack, future-Aku finally throws theatrics out the window and swiftly moves to crush them both under his massive hand; they make it without a moment to spare.

** It's not clear whether Jack's sword survived the final battle, or whether it was destroyed, either by the explosion or by losing its power along with its purpose. Regardless, it likely is no longer needed.
