** On the other hand, this is inverted with Kirei. See Smiting Evil Feels Good below.

* {{Sadist}}: In a similar vein to ''Fate/Zero'', Kotomine Kirei is a budding sadist living in denial. Unlike ''Fate/Zero'', Lupin is here to prevent Kirei from going full blown FortheEvulz-mode and help him find enjoyment in (slightly) more moral ways. See SmitingEvilFeelsGood below.

* EvilIsPetty: Assassin points out that this is all Zouken is during an awesome "The Reason You Suck" Speech. He points out that underneath all of Zouken's monstrousness is a bully who can only lord his power over people weaker than him and the only reason why he does the horrible things he does is because he ''knows'' that it is all he can do other than die.

* {{Sadist}}: In a similar vein to ''Fate/Zero'', Kotomine Kirei is a budding sadist living in denial. Unlike ''Fate/Zero'', Lupin is here to prevent Kirei from going full blown For the Evulz-mode and help him find enjoyment in (slightly) more moral ways. See Smiting Evil Feels Good below.

** Daisuke Akimi from ''LightNovel/KaraNoKyoukai''. In canon he just existed to give Mikiya leads. Here he's Zenigata's [[TheLancer lancer]] and [[NumberTwo right-hand man]] and is a competent detective in his own right.

** Daisuke Akimi, a mundane cop from ''LightNovel/KaraNoKyoukai''. He's more of a CanonImmigrant now because of The Nasuverse, and due to becoming a regular supporting character as Zenigata's partner.

* OldCopYoungCop: Zenigata and [[LightNovel/KaraNoKyoukai Daisuke]], respectively.

* UnfamiliarCeiling:
** [[spoiler:Sakura]] wakes up in the church after recovering from [[spoiler:having the crest worms taken out of her]]. She thinks she dreamed the night before until Risei confirms that Assassin brought her there.
** Waver wakes up in a hideout while recovering from [[spoiler:having his arm blown off]]. Rider explains where they are and why.

* WakingUpElsewhere: Irisviel wakes up in a hideout and learns she's been kidnapped by Assassin and Kirei.

* {{Troll}}: Not to the levels of SelfDemonstrating/{{Deadpool}} in TIM's [[FanFic/FateZeroSense other stories]], but Assassin certainly earns the ire of the three knight classes.

->''"W-who are you?” Kirei finally asked, making the Servant turn to him before grinning.\\
"Arsène Lupin the Third. Just an unorthodox thief."''

* BadassGrandpa: Zenigata may be past sixty, but that just shows how damn good he is since he can ''still'' compete with the new and improved, superhuman Lupin. The same could be said about a now-aged Jigen and Goemon.
* BadassNormal:

** The article of a newspaper [[spoiler: Rin]] has over her head mentions Monsiuer Zenith the Third facing off against [[Manga/DetectiveConan Kaito Kid]], a reference to the movie Anime/LupinIIIVsDetectiveConan

** Justified for [[spoiler:Zouken. Without the crest worms infesting Sakura, Zouken can't use her as a hostage, host, or plant, and Kariya's too far gone for the worms' removal to really matter. With Byakuya in jail and Shinji overseas, there's no one else around for Zouken to manipulate. The ''best'' he could do is run away on his own.]] .

* HoistByHisOwnPetard: In the epilogue, [[spoiler:MI6 agent Nyx is defeated by Kirei using Nyx's high-tech gadgets against him]].

* AssassinOutclassin: A flashback shows how Kiritsugu met Lupin III when the latter was still alive: Kiritsugu and Natalia had been hired to kill the Edelfelt head, and Lupin didn't want a murder happening on his watch. [[CaptainObvious Not only did the hit fail]], but [[OvershadowedByAwesome Kiritsugu realized how outclassed he was by Lupin and his gang]] even before Goemon [[ImplausibleFencingPowers cut down]] [[MonumentalDamage the Golden Gate Bridge]] to stop Kiritsugu and a few dozens police cruisers from giving chase.

* IgnoredExpert: Risei Kotomine. To his credit, he knows better than to underestimate Asassin because Lupin stole from the Church numerous times, including the [[http://en.wikipedia.org/wiki/Papal_tiara Papal Tiara]] within a day of his calling card and escaping the Executioners guarding there. Tokiomi brushes the concerns aside, but when Assassin not only survives Archer but delivers calling cards all over Fuyuki about winning the Grail, Risei all but says, "I told you so."

* CrowningMusicOfAwesome: [[InvokedTrope Invoked]] [[WordOfGod by the author]]. TIM has suggested some pieces of soundtrack for specific scenes.
** ''[[https://www.youtube.com/watch?v=g4mwKjoOhQY Afro Lupin]]'' for a Car Chase between Assassin and Zenigata.
** ''[[https://www.youtube.com/watch?v=j8IYmYreGWQ Wuthering Heights]]'' for a confrontation with Caster.
** ''[[https://www.youtube.com/watch?v=cRBQz-yd7-Q Super Hero]]'' for the Car Chase between young Kiritsugu (TIM admits the irony of the song title regarding Kiritsugu) and Lupin.
** ''[[https://www.youtube.com/watch?v=0xL5IQVg3Yk Elegy 1]]'' as the song for when [[spoiler: Lupin dies.]]
** ''[[https://www.youtube.com/watch?v=FX2ci_vr8o4 Lupin the 3rd Theme 80]]'', the theme standard for Creator/HayaoMiyazaki's work on the franchise, for a Car Chase between Lupin and the police after rescuing Sakura in Chapter 19, "Fourteenth Heist".

** [[spoiler:Zouken]] [[NoHoldsBarredBeatdown gets]] [[HumiliationConga what]] [[CruelAndUnusualDeath he]] [[UndignifiedDeath deserves]] [[spoiler:ten years earlier than in canon]]. [[CrowningMomentOfAwesome And it is ]]''[[CrowningMomentOfAwesome glorious.]]'' [[spoiler:Archer]] doesn't escape, either.

* EvilMakeover: Subverted. [[spoiler: Angra Mainyu's DyingCurse into [[MythologyGag what is essentially her]] [[SuperPoweredEvilSide Alter form]] from ''Heaven's Feel'', however unlike there Saber is [[HeroicWillpower able to retain her sanity]], though not without considerable effort as the Epilogue implies.]]

** [[spoiler:Sakura]] is taken in by Risei and eventually joins the Church.

** Despite delaying his rescue of Sakura, Lupin would never hurt a child himself.

** [[spoiler:Fujiko and Goemon]] go back to their daily lives.

*** Assassin also deems Zouken to be such a monster, so he gets more serious, wears his green jacket, and makes his fight with Zouken [[ItsPersonal personal]].

** The only reason Assassin doesn't kill Kiritsugu for sending [[spoiler:Pycal]] after him and causing a mess is because he wants to steal Excalibur from Saber and without Kiristugu, Saber will disappear.

** Kirei [[GenreSavvy admits]] to Kiristugu that he shouldn't make a speech during a fight, but [[InvokedTrope decides]] to do it anyway.

* GenreSavvy: Assassin is onto [[spoiler:Angra Mainyu]]'s true nature from the beginning. He repeatedly tells [[spoiler:it]] to cut the bullshit and does a better job of defending his argument than [[spoiler:Saber]] does.

* TemptingFate: The manager at the Fuyuki National Bank decides to advertise that their bank is safe from Lupin, a man who takes such things as a challenge.

* ForWantOfANail: Lupin's presence and actions turn ''Fate/Zero'' canon upside down. New alliances and rivalries arise, Servants are defeated in different order and in different manner, static characters like Saber and Archer get actual character development, and Kirei's character takes a turn for the better.
* FriendlyEnemy: Assassin and Zenigeta's relationship is this. Saber and Kirei are baffled by the concept.

* ChekhovsSkill: Lupin/Assassin's most iconic Noble Phantasm is claiming ownership on any item he steals. This allows him to prevent Archer's weapons from returning to the Gate of Babylon, to use and modify [[spoiler: Lancer's weapon after he died]], and even [[spoiler: [[CrazyEnoughToWork hijack the Holy Grail itself by touching the avatar]]]].
