History Characters / ItsAlwaysSunnyInPhiladelphiaCharlieKelly

* TheBabyOfTheBunch: While still the ButtMonkey who is taken advantage of, he's the closest thing to a MoralityPet the other members of the Gang have, and is constantly referred to as a "kid" despite being the same age as most of them. [[note]]For reference, Charlie Day is actually older than both Glenn Howerton and Rob [=McElhenney=].[[/note]]

* JerkassHasAPoint: Retroactively, as while he's grossly misogynistic telling Dee to not be a whore and try to sleep with him again, a few episodes later it's revealed she raped him when they had sex previously.

* RenaissanceMan: Surprisingly, despite his lack of intelligence, Charlie is shown to be the most artistically gifted and versatile of the group.

* SingleTargetSexuality: He shows an [[StalkerWithACrush unhealthy, often criminal obsession]] with [[NoNameGiven The Waitress]], at the least any dating story that doesn't involve her will have him at least mention her. In "Charlie and Dee Find Love" he dated Ruby for a short time, but it's revealed it was only to make the Waitress jealous. While he goes on several group dates alongside Mac and Frank in "The Gang Group Dates" Charlie explicitly says that he's only doing it to improve his game with the Waitress. However, he has slept with, or attempted to sleep with, hookers and strippers, and made out with Dee (who then [[spoiler: raped him]]). He had ''very'' explicit sex with a prostitute named Tatiana while on a ski trip, which can at least be explained by the episode's central mantra of "things are different on the mountain". After [[spoiler: he finally gets into a relationship with The Waitress and then it falls apart]], he and Frank end up having sex with two co-eds they meet through Airbnb in "The Gang Gets Romantic".
* SkewedPriorities: His main concern when the Gang are informed about a suicidal man on their roof is "we're not going to get our fish and chips".

** In "The Gang Go To Jersey Shore" he spends all his time finding random rocks and dead sea creatures, and The Waitress shows up at random. She actually seems pleased to see him and they spend the afternoon and evening together walking the beach and watching fireworks. In the morning [[WhatDidWeDoLastNight she doesn't remember anything because she was high on ecstasy]] and runs off. He takes it well, comparing it to a summer fling.

* TinyGuyHugeGirl: Charlie stands 5'6 and fits this trope when paired with Dee, who is 5'8. The two of them [[spoiler:have an impromptu hookup, later revealed to be a rape, in "The Gang Misses the Boat". When Dee insists Charlie didn't tell her to stop in "Time's Up for the Gang", Charlie claims he was too intimidated by Dee's "larger frame" to fight her off.]]
* TokenGoodTeammate: Charlie is the closest thing the Gang has to a moral compass and genuinely seems to have a good heart under his rage and idiocy. He's also the least racist when the rest of the Gang complain that all lives matter and it's black people's fault for only realising that "recently".
* TookALevelInKindness: Combined with TookALevelInDumbass; in Season 1, Charlie was a loser but not insane, and lied about having cancer and exploited an ex-girlfriend's child in order to win over the Waitress. After {{Flanderization}}, his actions seem more based in insanity than maliciousness, making it easier to sympathize with him.

* TrademarkFavoriteFood: The mysterious "milk steak". His addiction to cheese is also a RunningGag.

* WildCard: Mac assigns him this role in "The Gang Solves The Gas Crisis"; however, it ends up deconstructed when Charlie's randomness ruins the Gang's plans in the same episode. In the sequel "The Gang Recycles Their Trash", the rest of the Gang, now knowing better, have to get rid of him so that their get-rich scheme can actually succeed.

* CreepyCrossdresser: Subverted. It's revealed that he can only poop while wearing a dress as a result of his mother's coddling. As a result, he typically poops in the women's bathroom, where the cross-dressing is less likely to be challenged or even noticed. [[Note]]In the script for the episode, Charlie reveals he actually believes he may be transgender. As this was removed for final production, he remains only a quirky crossdresser.[[\note]]

* ConditionedToAcceptHorror: He ''is'' actually aware of it and constantly trying to get away from Uncle Jack, but he makes a "fun" musical about the nightman (i.e his childhood molester) and becoming his abuser. The others try to tell him it sounds like sexual abuse, but he's having none of it.

* CreepyCrossdresser: Subverted. It's revealed that he can only poop while wearing a dress as a result of his mother's coddling. As a result, he typically poops in the women's bathroom, where the cross-dressing is less likely to be challenged or even noticed.

* DisappearedDad: He never knew his birth father. [[TheUnreveal It may or may not be Frank]].

* DumbassHasAPoint: In "Charlie Work", while preparing for a visit from the health inspector, Charlie discovers the Gang in the midst of a scam involving live chickens, prompting Charlie to tell them to move the chickens away from the front of the bar. When they ask him why they should do it, he tells them that even if they don't care about the inspection, it's still not a good idea for a government official to see a scam happening in plain sight. The Gang quickly acknowledges he has a point and moves the chickens.

* ThePigpen: He lives in squalor and has limited personal hygiene. Mac says that he has never seen Charlie put on deodorant.

* {{Flanderization}}: He went from "somewhat awkward, sometimes loud, and occasionally dim-witted, with a mild crush on this one waitress" to "entirely illiterate, possibly insane and ''definitely'' a savant, StalkerWithACrush and NoIndoorVoice." The episode "Flowers for Charlie" actually gives an InUniverse justification for this change, as it is explained that the much of the work the Gang has assigned Charlie to do around the bar involves him frequently handling a pontent cocktail of various dangerous chemicals, implying his increasing stupidity, illiteracy, and unhinged behavior to be the result of ever-worsening brain damage from exposure to said chemicals.

* SingleTargetSexuality: The Waitress, for the most part. In thirteen seasons, Charlie has dated exactly one other woman, with the sole intention of using her to make the Waitress jealous. While he goes on several group dates alongside Mac and Frank in "The Gang Group Dates" Charlie explicitly says that he's only doing it to improve his game with the Waitress. However, he has slept with, or attempted to sleep with, hookers and strippers, and made out with Dee (who then [[spoiler: raped him]]).
** He had ''very'' explicit sex with a prostitute named Tatiana while on a ski trip. The latter instance can at least be explained by the episode's central mantra of "things are different on the mountain".
** After Charlie's relationship with [[spoiler:The Waitress]] falls apart, he and Frank end up having sex with two co-eds they meet through Airbnb in "The Gang Gets Romantic".

* SingleTargetSexuality: The Waitress, for the most part. In thirteen seasons, Charlie has dated exactly one other woman, with the sole intention of using her to make the Waitress jealous. While he has slept with, or attempted to sleep with, hookers, and strippers, and made out with Dee (who then [[spoiler: raped him]]), Charlie explicitly says multiple times that he's only doing it to improve his game with the Waitress.

* DumpsterDive: Charlie frequently searches through dumpsters to scavenge items for himself or his apartment. He also goes through the Waitress's trash as he thinks that's a way to get to know her.

** When he complains that the Waitress won't leave him alone after she [[spoiler]] baby traps him[[/spoiler]], Dee angrily points out that he's been stalking her for fifteen years. Charlie quickly ignores it and forces his way into hiding out at Dee's apartment.
