History Characters / Trainspotting

* JailBait: Mark Renton has sex with her, discovering the next morning that she is fifteen when she appears in her school uniform and her "flatmates" are actually her parents. Later, she threatens to tell the police if he does not see her again.

* CharacterDevelopment: The first time around, both book- and movie-wise, Dianne is portrayed as a sex-crazed, club-hopping teenager; by the time ''Porno'' comes up she's toned her recreational drug use down and she matured into a pretty well-adjusted university student, working on her thesis and being more than capable to hold her own in a conversation. She still loves to party, though. In the film continuity, she's a lawyer by the time ''[=T2=]'' rolls around.

* YourCheatingHeart: He cheated on Fiona with Joanne in ''Skagboys''. It's something he feels very guilty about though.

* SpeakIllOfTheDead: isn't sad about either of his brothers being dead, with Billy being a BigBrotherBully and the handicapped Davie being an embarrassment who took all their mother's attention.

* YoungerThanTheyLook: Mark Renton meets her in a club, then goes to her house where they have sex. Immediately after the act she kicks him out of her room and he sleeps on a sofa. In the morning it's revealed that she's underage. She even threatens to report him for sex with a minor if he doesn't see her again[[note]]Renton is either unaware of, too paranoid, or too drugged-up to realize, the fact that meeting her in a club pretty clearly indicates that she ''should'' be of age, or else not have been allowed in. A public defender (or whatever the Scottish equivalent is) 10 minutes out of law school would get him out of any trouble she tried to get him in. However, this is mitigated by the fact that Renton is hungover, panicking and just wanting to get away from the situation; in the book he can't stop thinking about how Begbie ''hates'' peadophiles and the fact that if Renton ends up in prison, he won't be safe even there from Begbie's wrath, so his reasoning is clearly overwhelmed by paranoia. Sleeping with her again ''after'' he knows her true age, on the other hand . . .[[/note]].

* TheSouthpaw: Whenever he's seen writing, he is seen to be left-handed, as is his actor, Ewen Bremmner.

* UneliableNarrator: He narrates his own chapters in ''A Decent Ride'' but gives no indication that it was him who stole [[spoiler:Ronald Checker's prize whiskey]] until he retrieves it from its hiding place.

* BiggusDickus: He's pretty well hung, which makes him perfect for Sick Boy's porn movies.

One of Begbie's inner circle. [[Literature/MarabouStorkNightmares A major player in the Capital City Service in his youth]], known for leading his boys with soap bars in socks to attack Rangers fans. Participated in [[spoiler: a gangrape on an unfortunate girl]] but never saw punishment for it. Runs a furniture shop with Begbie until Franco gets put away for an extended period of time, during which Lexo decided to rebrand it as a Thai dinner with his partner being non-too-happy when he finds out. A cousin of Martin Gentleman, Dozo Doyle's right hand man. Notable for having roles which range from minor to significant in ''Nightmares'' all the way through ''{{Porno}}''.

* KarmaHoudini: It's difficult to parse out the narrative of ''{{Marabou Stork Nightmares}}'' as it's such a MindScrew. But according to the chronology of all the novels, it seems that Lexo got away scott-free with [[spoiler: the gangrape]] in that book. This is in contrast to his accomplices, all of whom suffer exploitation-film level revenge by the end.

* EmbarrassingDampSheets: Wakes up in his girlfriend's bed and realized he's drunkenly pissed, share and vomited all over the sheets. Everyone's all right about it until he accidentally empties the contents of the sheet over her parents.

* StickyFingers: Well known as a burgler, something he took to after he lost legitimate employment.

** BiTheWay: In the cinematic canon, taking into account that he's gotten married at least once.

* BiTheWay: He ends up hooking up with a few men over the course of the novel, and doesn't see it as a big deal, although he feels more comfortable with women.
** AdaptationalSexuality: His flings with men are absent from the film, but the relaxed attitude towards same sex relations remains in place, making him AmbiguouslyBi in the film.

* ScrewySquirrel: As Renton puts it...
--> ''The mischief making cunt staggers through life leaving these interpersonal booby-traps for his mates. What fucking pleasure the radge derives fae these activities is beyond me.''

* TheTeetotaller: He's been sober for six years by the time of ''The Blade Artist''.

* EvilAlbino: Hence the nickname.

* InformedAttribute: He's supposedly an extremely disgusting human being, but compared to Francis Begbie and Alan Venters, he comes off as just a lovable rogue. [[spoiler:He does become a lot worse in the sequel. He's not above blackmailing city officials and pimping out girls for his own ends.]]

* YouLookFamiliar: Brenner had played Renton in the stageplay before starring in the movie.

* AdaptationalSexuality: His actor and director both consider him a closet gay but this wasn't Welsh's intent when writing the book.

* TheSociopath: Exhibits many of the qualities associated with low-functioning psychopaths, such as superficial charm, manipulation and a constant need for stimulation, not to mention his violent outbursts and inability to take responsibility for his actions. It's also revealed he harmed and even killed animals in his youth, which is an early indicator of psychopathy (albeit his companion Renton also abused animals, but is comparatively much more mentally sound]]. By the time of ''Skagboys'', Begbie has just begun to blossom as a hardcore psychopath, through a combination of genuine mental disorder, environment, and being built up as the ultimate badass by his friends. He appears to have [[SubvertedTrope subverted]] it by the time of ''The Blade Artist'', displaying what appears to be empathy, positive emotion and love, [[spoiler: but he has ultimately just become better at hiding his psychopathic urges]]. Even saying that, though, those good attributes do seem to be fully in effect with regard to his new family, if perhaps ''only'' for them, and maybe Elspeth's small family too. This novel also identifies him as suffering from Intermittent Explosive Disorder.

* YouLookFamilar: Brenner had played Renton in the stageplay before starring in the movie.

* BullyingADragon: At the end of ''Porno'', he taunts a comatose Begbie while drawing penises on his face. The book ends with [[spoiler:BolivianArmyEnding Begbie opening his eyes and grabbing Simon's hand.]]

* DemotedToExtra: Doesn't appear agin in the play after the cot death. The same actor plays Tommy who gets more stage time.

* EvenBadMenLoveTheirMamas
