History Characters / BulletTrain

-->'''The Prince:''' ''(about Yuichi and Wataru)'' [[SmugSnake They are both dead.]]
-->'''The Elder:''' ''(smirking)'' My grandson was pushed off a roof. [[spoiler: [[DidYouActuallyBelieve What makes you think I would leave him unprotected?]]]]

* PapaWolf: His above quote, [[spoiler:which he ends up illustrating when he has a Yakuza assassin disguised as a nurse murder The Prince's hitman that was stationed to kill Wataru (his grandson) and forced Yuichi (his son) to work for Prince.]]

* MaternalDeathBlameTheChild: Variation. His wife didn't die in childbirth, but in an accident on the way to pick up their useless son from the police. [[spoiler:The White Death then conspired to have their son killed along with everyone else he blamed for her death]].

* OccidentalOtaku: {{Implied|Trope}}. He is from Russia, but becomes the top crime boss in Japan and also demonstrates proficience with a katana and wears an ''oni'' mask at one point -- and outfits his assassins with similar facewear.

* AdaptationalBadass: Where the book version of the handler does [[spoiler:try and reach the train's terminus to help Ladybird]], she's incredibly bad at it, turning up late due to falling asleep (she had watched all the ''Franchise/StarWars'' films the night before) and then getting on the wrong train. The film version, on the other hand, is shown at the end to have been [[spoiler:traveling unceasingly toward Ladybug]] as soon as she realized something was wrong. While she still arrives late, it's not from any lack of effort on her part.

* ReptilesAreAbhorrent: Played with. The snake itself is just an animal. Its venom is used by an assassin, but they go by The Hornet, and don't have a snake theme.
* VillainyFreeVillain: Its just a snake. It hisses at, then later attacks Ladybug, but doesn't have any sinister agenda, its just acting on its instincts.

* MoralMyopia: [[spoiler:He orchestrated the movie's entire plot to seek revenge on those he blamed for his wife's death, but callously mocks the Elder's quest of retribution against him for murdering 'his'' wife.]]
