While he seemed to stagnate, some of that seems to do with his heart being frozen and locked away. His attempt to write a sexy screenplay that was still friendly to feminists resulted in him remembering to fix it.
He later tries thawing his heart only to find out he doesn't know how. His Google attempts only lead to the Devil's drones getting weird info since the search engine wasn't sure what he was asking.
We have now seen some ramifications. Xanthe implies that his empathy issues are due to this (though she doesn't realize it when she implies it) by noting that his screenplay lacks any real emotion or heart. Slick even flashes back to his locked-up heart when she says it.
Or all of this. The net result, however, is exactly the same.
And with the Sisterhood arc, their relationship gets considerably worse. Slick and Monique largely cease to interact at all. And when they do, he insults her with Victim Blaming, suggesting it's her fault her so-called "fans" are Straw Misogynist jerks. Monique calls him out on this and eventually forms a Romantic Two-Girl Friendship with Absinthe.
Older Than He Looks: He is occasionally mistaken for a child. He is more than 35, since he's run for president three times. Though considering it that this is Sinfest, that might be due to Rule of Funny. Judging bu his attitude and nature, he seems to be in his mid-20's.
He's disappointing when this stops earning him cookies and many glitter points. but even the half point he earned was enough to keep Kcils trapped in his own world and not able to affect Slick for the night.
A hippie feminist girl who is the main target of Slick's attentions.
Cool Big Sis: Treats Criminy as a little brother. In "Gypsy Nique 5", she was getting ready to attack Fuchsia because she thought he was under threat.
Also briefly to an "It Girl" fan.
Does Not Like Men: After the Sisterhood opens her eyes to the predations of the many Straw Misogynists and her own role in it, she begins fighting back. Her "fans" respond with abuse, throwing tomatoes and insults at her. She eventually comes to realize that they never really respected her at all and only liked her as the embodiment of some fantasy in their head rather than for who she really is. Her response is a desire to beat them up.
Counts as a hypocritical moment given her past of being The Tease and sending a million men to hell.
Noted here where she seems to wonder if she's any better than the her who teased men and broke their hearts on purpose.
Even the Girls Want Her: As Androginique, she asks a random girl to be friends with benefits... and gets her number.
I Hate Past Me: Delete all the old poem files on her computer, burns her old poetry books, clothes and statues from her It Girl period. Also, the guilt she feels for her past as a cockteaser and heartbreaker returns.
Your Approval Fills Me with Shame: She starts regretting her attention whoring after accidentally tempting guys into eternal damnation with her demon cosplay, but it's getting paychecks from Hell, along with Blue's "congratulations" that drives her into changing her image.
Badass Bookworm: Criminy. He breaks into Hell, and later tames a demonic, flying pitchfork and rides it out through the ceiling and perceives a toothed flame-breathing demonic book as an "interesting challenge".
Beware the Nice Ones: The end of the Bad Behavior series is the first time he's ever been pissed off in over 10 years.
He has been shown capable of his own against a sentient demonic pitchfork with just a shovel.
He then flies out of Hell while being pursued by a Succubus (relax Fuchsia got zapped, but it did not take) mounted on the SAME pitchfork. He scares the shit out of Lil'Evil and buzzes past God. If that's not bad-ass, then nothing is.
Serious Business: He pulls off several Parkour moves to get to a burrito place right before closing. He also pawns his entire porn stash (it hit the ceiling, not counting the stuff on his PC) for some kind of deluxe taco shop special.
Seven Deadly Sins: He's gluttony: Big Eater, stoner, drinker, avid consumer of porn... Although he now and then gets sick and tired of his lifestyle and starts dieting, exercising, dropping the intoxicants, and throwing his porn away. For a while.
Sky Surfing: He can actually fly when using drugs and can carry other people with him.
Strawman: Used as such depicting "Sex Positive Feminism" as something that doesn't exist and is just misogyny in disguise. Ironic in a Critical Research Failure way considering that the term "Sex Positive" was invented by women.
Straw Misogynist: More specifically, a straw 3rd wave feminist, which is portrayed as a thinly veiled excuse for disgusting misogynistic behavior. Charitably, one can claim that it's less the philosophy under fire and more the people who only have a superficial understanding of it, like Squig.
The Stoner: ... To the point of using pot to allow his sofa to fly (even into, and then back out of Hell). He later tokes up on the toilet. This leads to said toilet blasting its way through the roof and eventually landing in the tree Fuchsia and Criminy hang out at. Needless to say, they pull him down, but not before the flight of the toilet ends up on Twitter and a ton of other social networking sites.
Magical Girlfriend: Played With. Being an immortal demon presents its perks and problems... but Criminy takes no issue with either.
Mama Bear: Attempting to make a trophy out of her pet is a VERY bad idea. The only thing that stopped her from killing Little E was Criminy's earlier visit cheering her up after her Despair Event Horizon.
Mayfly-December Romance: Although the implications aren't discussed, it's mentioned that succubi have eternal youth.
Sexy Secretary: Takes on this look when she wants to come across as more professional in her business of sin-accounting. She has taken to wearing it more frequently as events (and characterization) have marched on.
May lean towards Designated Villain, as she seems to practice (in her own strange way) Christianity. She even sanctifies Lil E.
Ax-Crazy: Probably the most violent character in Sinfest. Is plotting to kill Santa/Satan (her pronunciation makes it unclear). She's also taken to "killing" pastries.note Or rather, "fighting the pastry-arky."
Evil Feels Good: While probably not coming from any sense of sadism, she relishes in "bomfing" whatever she feels like on a whim, describing it as "fuuuuun". To be sure, when she sees it used to actually blast someone to Hell, it clearly unnerves her.
The Fashionista: Has twice shown interest and desire in other characters clothes.
Good Feels Good: Assures Lil' E of this — though she may overestimate how much she is a force for good.
Morality Pet: Has some shades of this towards Seymour, incredibly. If nothing else, he has acted more decently when around her than at any other point in the comic. Their interactions aren't numerous yet, and Seymour's "gentlemanly behavior" might just be him feeling responsible for her (as he's responsible for her Cloudcuckoolander attitude), but there's hope yet.
Either that or he's at a loss when someone heeds his sermons only to run with a completely garbled version.
No Name Given: For the first three years after her introduction. The name Pebbles comes from one strip, where Monique nicknames her Pebbles due to her orange hair. Tangerine was proposed by the fans to go along with the Theme Naming amongst the other succubi. In March 2014, her real name was finally revealed as Angie, a.k.a. Tange — possibly short for Tangerine.
Obliviously Evil: Tangerine doesn't seem to bear ill will to anyone she doesn't perceive as attacking her or "Lily". Being an impulsive, childish, slightly "out of it"Pyromaniac is enough to occasionally make people run away screaming, though.
Pyromaniac: Loves to make things go boom. Especially after she gets Seymour's shotgun.
Running Gag: Her habit of stealing pieces of clothing from people she runs across is starting to shape up as this.
Ms. Fanservice/Fanservice Extra: Deconstructed; because of the misogynist men in-universe, she just can work as a stripper, even though she hates it, she's harassed for creepy paparazzi or fans of her and she's treated just like eye-candy.
The strip that hints that God actually created Seymour fully formed and acting the way he is becomes either hilarious or His Moral Event Horizon by proxy when taken into light the things Seymour does because of said obsession.
All Hail the Great God Mickey!: Has recently started mixing his worship of Jesus with that of Voltron. Whether he thinks Voltron is a saint or an actual avatar of Jesus isn't entirely clear.
Non-Standard Character Design: It's interesting to note that, although he is human, God accidentally created him to look like one of his hand puppets, which might explain why he looks so different from the other human characters.
Bullying a Dragon: Crosses into Too Dumb to Live territory. To Fuchsia. He also pisses off Criminy, the guy who dug into Hell to be with his girlfriend. Before that, he literally pokes the Dragon's nose.
Characterization Marches On: Do you remember when being a closeted homoseuxal wasn't his defining characteristic? Or, to speak of, when, initially, for a long time there was no indication for Seymour being gay at all?
Egomaniac Hunter: In a manner of speaking. His hunting gear and shotgun is his second most worn outfit, and he is an egomaniac, but he's not egomaniacal about his hunting skills in particular.
Elephant in the Room: No one, not even Seymour himself, ever seems to notice that he looks...unique, even in a world where humanoid pigs and devils are common citizens.
Fantastic Racism: Towards Fuchsia, who has been actively trying to change her ways, making it even more repulsive.
Though later in his Character Development he softens toward her considerably. He often has admiring things to say about her painting skill in particular. Though this might just be because he is trying to butter her up so she can paint things for him (which after his previous behavior toward her she is not inclined to do.)
Fate Worse Than Death: An epically hilarious one in Bomf 4. Turned into the thing he hates as an ironic reflection of his true nature.
Flanderization: He actually had a few decent moments at the beginning, and was no worse than anyone else, but while everyone else has gotten Character Development and Lighter and Softer treatment, he became more and more intolerant and intolerable in his fervor... and then finally learned something and has since begun to be less Flanderized.
Light Is Not Good: Jesus fanboy? Check. Averse to demons? Check. Jerk? See the rest of his tropes.
Loony Fan: Hilariously enough, he fails to recognize the real thing in person. Despite having bought a metric fuckton of Jesus merchandise. MIGHT be a Metaphor for his obsession with the rule of his religion, and not the spirit of it.
Pure Is Not Good: Is convinced that he is almost completely without sin, and truly has done little that could be considered evil in the usual sense. Which just makes all the times he acts Holier Than Thou that much more despicable, knowing he could be good but is too much "against evil" to truly be good.
Windmill Crusader: Takes his struggle against the Devil and his minions seriously. So seriously, he forgets not all of them are bad, or that he isn't a threat to them, in the slightest. The Devil doesn't pay attention, unless there's an easy opportunity to torment him.
Double Standard: Standing up for women in a society that is bent on exploiting women is a fine attitude. However the fact that she's not only completely indifferent to male suffering, but runs her bike on it suggests that she's less interested in removing the double standard than reversing who's in charge.
Upon actually encountering a demon outside of Satan, (Milton to be exact), offering to fix her trike, she somewhat coldly but politely states no thanks.
She also seems to be taking Slick's attempts to change more seriously later on, even though sometimes her advice confuses him especially the time she referenced Kcils, who he doesn't seem to know about.
Heroic BSOD: Went into one for a bit when she thought there were no male allies to feminism. Nana helped her out of it.
Hero Stole My Bike: MMXII steals her trike to get away from Death, and then accidentally sets off the self-destruct sequence.
Jerk Ass: Much like Seymour, many fans feel that she forces her fanatical views down people's throats. But aside from her total Lack of Empathy for Straw Misogynists, the comic usually seems to portray her actions as being in the right.
Chekhov's Gun: Their "glitter points" apparently have the power to protect the pure of heart from minor demons and can temporally remove demonic corruption from the Devil's minions (they still look like demons, but they lose the personality).
No Accounting for Taste: Even with a shot of love, Sam And Liberty's marriage is getting more and more troubled. Sam hasn't stop with the porn but now, he wants Liberty to try porn sex without considering that sometimes porn can be unrealistic, claiming it can make them a stronger nation and it's "liberating" and excuse his low preferences on porn with searching what women want. Liberty of course feels uncomfortable and creeped out about it.
Robot Girl: Going into the Reality Zone activated her "autopilot mode" and has granted a kind of freedom after her remote control exploded. Even, it seems her default mode is a sassy behaviour. She could pass for a real girl if it wasn't for her needing tech support.
Technopath: Percy, by complete accident. Every time he steps on an electronic device, it's some valid combination of buttons that will somehow make life slightly more miserable for his owner, such as ordering 50 cases of feminine anti-itch cream or making a "cat goatse screensaver".
