Berserk Button (Don't show her ANY video game made by LJN if you want to keep it intact unless it happens to be inside a video game store. Even then, she'll go into a profanity-laced tirade about how LJN ruined NES games for everyone with their licensed crap. Also, even insinuate that she'd look good in a dress, and don't expect to see a fury even close to the result from Hell itself; while Michelle never makes that mistake, she does know Lina well enough to know the consequences of such insinuations, as seen in episode 40:)
Deuce: Try wearing a dress for once, bitch! Cure Western: You talking to me? Cure Action: Uh-oh, he imagined my friend wearing a dress! Cure Western: You talking to me!? Cure Action: He shouldn't have done that! Cure Western: YOU TALKING TO ME!?!?!? Cure Action: Now he's in for it! Cure Western: Me—in a dress!?IN YOUR DREAMS, MOTHERFUCKER!!!!!! [Cure Western proceeds to start beating Scratch to a pulp]''
Bifauxnen (she virtually is one, even if her usual attire is gender-neutral, and then, after getting her eye gouged out, she starts wearing a black leather jacket whenever and wherever possible.)
Civvie Spandex (her Cure outfit and Super Cure outfit basically consist of a gold tank top and cuffed jean shorts)
Country Matters (In episode 23, when Scratch makes himself known by offing Krueger, she lands a Precision C Strike — a rare monent in anyPretty Cure series where someone says the word. Predictably, the very first word of Gratuitous Russian she speaks in-series is the worst in that language, its equivalent of "dick".)
Cybernetics Eat Your Soul (Noticeably averted; Lina is still perfectly human despite having a cybernetic eye starting in episode 23, though she usually wears an eyepatch around unknowing individuals who think this trope would apply to anyone. When Michelle expresses her concern about the effects the new eye will have on Lina's soul at the start of episode 24, she responds by asking, "Have you been reading too much Gunslinger Girl?")
Dame Swears-A-Lot (She's the most sailor-mouthed of the cast, by far. Of course, it gets really interesting when she Bales Out in a later episode...)
Dance Battler (She's revealed to have shades of this in episode 50; while her capoeira training is subtle in most of the fight scenes, she goes all out with the capoeira in the last episodes.)
Also, even before she swore off blasphemy in a later episode, she'd sometimes take the Lord's name in vain when really angry, but she'd never blaspheme against the Holy Spirit.
Evil Laugh (OK, she's not really evil, but she regularly employs this. The one she delivers right when she pummels Scratch and takes his eyes out as revenge for taking one of her own eyes out is rather chilling, though. Another notable example is when she sends a homing bullet in Nick's direction. And then there's this little gem from episode 26:)
Lina: Guess what today is, you sick mother? The day you meet your death! And you know what your gravestone's gonna say? "Cyclops slain." Heh heh heh heh heh heh...
Expy (Like Shugo Kino before her, her character design is clearly inspired by Emma Watson's looks — post-haircut, in her case.)
Mistaken for Racist (In addition to her constant profanity, she seems to enjoy throwing in the odd ethnic slur, much to the author's disgust at having to type them into his episodes. So far she's used "dago", which earned her a slap from the newly-converted Fannie; "gook", which she uses to refer to Kim Jong Il during a politically-loaded rant against Communism; "kike", or more specifically, "kike hater", which she uses to refer to Nazis; and "spook", which is the farthest she's willing to go when referring to blacks.)
No-Holds-Barred Beatdown (She gets a few of them, but episode 51's beatdown scene is the most horrific, as by the time it's over her corpus is really battered and bruised, and she's near death. Of course, only old-fashioned punches, kicks, guns, and/or knives are involved on both sides in all of them.)
Product Placement (As far as advertising PBS by inserting P-Heads everywhere goes, Lina is a frequent offender, as the P-Head appears on her gold top, facing either the right — with a split — or left — without a split — depending on the season.)
Tights Under Shorts (Her gold thigh-highs change into gold tights in episode 52, right before the climactic showdown against Lucifer. And that's the only real change to her Super Cure outfit.)
Token Evil Teammate (Like Shugo before her, Lina fits this trope just for being more antiheroic than the rest of her teammates. Lampshaded in episode 16 when she flat out says, "Yep, I'm evil" right after Alex tells Fannie how Lina is addicted to violent video games and swears a lot when she's not attending classes at Hollywood High.)
Who Wears Short Shorts? (She wears cuffed jean shorts in both her Cure form and her Super Cure form, the latter whom even pairs it with Grade B Zettai Ryouiki! Lampshaded at the start of episode 23 by Krueger:)
Expy (she's basically a female, more competent version of Inspector Gadget; her origin story even mirrors his from The Movie, as she starts out as a mild-mannered high school student and becomes a cyborg to save her life following a fatal accident she almost never recovered from)
Gratuitous French (she sings an entire song in French in episode 28, for crying out loud!)
How Do I Shot Web? (she has to be shown the ropes by the scientist that saved her life and, in earlier appearances, is seen studying her manual so she can get the hang of her new cyborg abilities)
Red Shirt (subverted at the end of her first episode, when she's blown up by a victory cigar bomb and brought to a robotics laboratory by her new friends for a life-saving surgery that will turn her into a cyborg)
