Large Ham/No Indoor Voice: While Connor does have his quiet badass moments (such as during the "kill 'em all" speech at Rocco's place), when he gets going, it's with all the Hot Blood of his general nature.
Pet the Dog: While in the hospital, he plays with a sick child despite his own wounds.
Sensitive Guy and Manly Man: Averted, in that Connor's Hot-Blooded nature makes him both more emotionally open and prone to ridiculous feats of manliness. Not to mention it is implied that he got his looks and outgoing personality from his mother.
Spell My Name with an S/Adaptation Decay: In the credits and subtitles of the first film, he's listed as Conner MacManus. In the first movie's shooting script and the sequel, he's listed as Connor.
(In Russian) I'm afraid we can't let that one go, Ivan.
Cold Sniper: To a lesser extent than usual for the trope. He still shows no qualms about hitting girls who hit him (or Connor) first, shoots a not-quite-dead mobster without blinking, and stabs one of the mob dudes who captured them in the back repeatedly with a broken hand. Most likely from his father's side of the family, as Noah MacManus also had the pale-skinned dark-haired look (when he was younger) and tendency to smoke.
Deadpan Snarker: Whenever Connor's plans involve something from a movie or TV show, this side comes out in full force.
Red Oni, Blue Oni: Blue to Connor's Red. Murphy is the more grounded and compassionate of the two.
Sensitive Guy and Manly Man: Played with. He is the calmer, nicer of the two twins as you can see when Rocco fights the hitman, he goes to help Rocco before Connor makes him "prove himself" and when Connor's not looking provides Rocco with a weapon. Being pale, withdrawn, and more lightly built than Connor makes him appear somewhat frailer... until he getsreally mad, that is.
Smoking Is Cool: Smokes a lot more. Played almost literally in a deleted scene, where Murphy lights up right before he takes a shower and promptly complains that Connor used up all the hot water. May also be inherited from their father.
Freudian Excuse: When Il Duce was younger, his father was murdered by mobsters before his eyes.
Improvised Weapon: In the comic, he and Louie end up defending themselves with everything they can get their hands on in the leather shop. Louie's heavy metal leg brace even serves as a way to strangle a thug.
Shipped in Shackles: Il Duce (who provides the page image for this trope) is introduced in the first film being moved from his cell to the ground floor for a parole hearing. He is cuffed hand and foot, chained to a rolling platform, and wheeled down to the parole board. The entire prison is put on high-alert, with shotgun-wielding guards on every floor, all to move one man down a few flights of stairs. Once he's there, they even put him inside a metal cage to protect the parole board. All of this serves to establish the guy as a hard-core Badass.
Throw Away Guns: His signature gun vest. Justified, as it makes a seasoned FBI detective believe he was six men instead of one, making it harder to be traced to him.
But Not Too Gay: Played with as Smecker is actually the most sexual of the main characters, but he doesn't cuddle and he seems annoyed with most gay men unless they are actually having the sex. After the sex, not so much.
Large Ham: Probably the biggest ham of the first movie, especially during that scene.
N-Word Privileges: Averted, and played for humor at the same time. He repeatedly calls other gay men homophobic slurs, and is unfailingly given dirty looks. At the very least, he doesn't seem to mind when it's directed at himself, either.
Not So Stoic: While he's a little weird from his very first appearance, he is generally calm and collected. As the bodies begin to stack up, he becomes increasingly frayed, bordering on Sanity Slippage, leading to his quote above.
Straight Gay: He appears to play up the Camp at times to poke fun at himself. And to discombobulated straight cops.
Wholesome Crossdresser: He does this to infiltrate the Big Bad's mansion, and gets a little too into character. It inadvertently ends up saving his life, since Il Duce mistakes him for a woman from behind and simply knocks him out.
You, Get Me Coffee: Whenever Detective Greenly would say something stupid or mouth off, he would be dispatched to fetch coffee and bagels.
Special Agent Eunice Bloom
I am so fucking smart, I make smart people feel like they are retarded.
Defrosting the Ice Queen: She comes off pretty cold most of the time, but hugs Il Duce with tears in her eyes as she asks them to kill The Roman.
Male Gaze: Troy Duffy got Julie Benz to be in his movie, and damn it all if he wasn't going to take full advantage of it for his male audience! To be fair, this was after plenty of shirtless and/or naked Irish twins.
Ms. Fanservice: High stiletto heels, cowgirl outfits, shorts skirts, hair color changes. You name it, she most likely does it at some point in the movie. It's even lampshaded by Smecker when he remarks about the length of her skirt at his funeral.
Eunice: "With all due respect... man, I hate it when people say that because it is inevitably followed by a disrespectful remark. Here let me give you an example: With all due respect, detective, this matter falls under whatever jurisdiction I fuckin' say it does."
Subverted in the second movie, as they intentionally take all the details and come up with wrong conclusions, because they are trying to cover for the Twins, and themselves by association. Until they realize that Eunice Bloom is on their side and is just having fun toying with them.
Overly Long Last Name: If you're wondering why a South Boston detective has the imposing name of Dolly, it's because his actual last name is Dollapoppaskalious. This is lampshaded in the first movie when Smecker manages to pronounce it.
Dolly: Holy shit. You're the first one that's ever got that.
Smecker: What can I say? I'm an expert at Nameology.
Wrong Genre Savvy: The reason they have such a hard time figuring out what happened is because they don't realize the men they are after learned everything they know from watching bad television. Every overdone action movie trope that never happens in real life happens to or is invoked by the Twins.
Cool Old Guy: He's completely okay with letting the Saints, a pair of wanted murderers, stay at his place for the second movie. Even in the first one, he's egging them on as they trash his bar beating up Russian thugs.
Hollywood Tourette's: Averted. While Doc does display coprolalia (foul language), he also has the stuttering and motor tics most Real Life Tourette's sufferers have.
Butt Monkey: Both from his fellow mob dudes, who call him "The Funny Man" and make him tell racist jokes, and from the MacManus brothers, who mess with him every so often and put him on "bitch detail" during their jobs. Not that he didn't deserve it.Remember the stripper? But in contrast to the mafia's decision to just get rid of him, Connor and Murphy go ballistic when Yakavetta murders him.
Fingore: Rocco loses a finger during the big shootout with Il Duce, which is used by Smecker to finally gain his lead on the brothers. Another finger gets shot off at point blank range with Papa Joe's .357 magnum, shortly before the mob boss decides to just kill him.
The Farmer and the Viper: Louie uses the Scorpion and Frog fable variant to explain why he betrayed Noah after they had worked together for so many years. But he also ruminates that like the scorpion, he lost everything by his betrayal, because he was no longer useful to the Mafia.
Unwitting Pawn: He religiously followed the orders of the Roman, completely unaware that Louie was actually trying to bring the Saints and their father back so they could eliminate the Yakevetta family in revenge for casting him out.
