Most of the CollegeHumor actors play fictionalized versions of themselves along with various alter-egos, so on this page they are sorted by actor first name in alphabetical order. Tropes and comments in the list below refer to the fictionalization of each actor, unless otherwise stated.
- Serious Business: In "Sensual Harassment", his tendency toward public aesthetically and artistically sensual gestures (soft-focus photography of himself, strawberries dipped in melted chocolate, scented candles, tai-chi in a kimono, reading poetry on a bearskin rug surrounded by rose petals) are treated by Amy Schumer as though he were committing sexual harassment.
- Silent Scapegoat: Becomes one in "Fart Martyr".
- Open Mouth, Insert Foot: Repeatedly when they run into their ex.
- The Pig Pen: Judging by their car.
- Ret Gone: Suffers a bad case of this in Everyones Favorite New Cast Member.
- You Know I'm Black, Right?: In "Sleepovers When You're Gay", their friends seem unaware that Ally is a lesbian (or even that lesbianism exists) and engage in oblivious erasure, despite their attempts to express themself.
- See the character sheet for Jake And Amir.
Brennan Lee Mulligan
- Ignored Epiphany: In the Venmo sketch. He comes to the realization that the reason people don't use Venmo like Facebook is that every post needs to be accompanied by a transaction... and then dismisses the thought.
- Only Sane Man: Plays this in the ABC and Tide Pods sketches.
- Rant-Inducing Slight: Never ask to order off of a menu when he's around.
- Serious Business: Takes coming into work very seriously
Brian "Murph" Murphy
- No Social Skills: His alter-ego, Tedward from IT, has never seen or heard of anything. Not even Game of Thrones.
- Suicide by Sea: His departure from CollegeHumor was marked by a sketch in which he walked into the ocean to die.
- The Unintelligible: The main characteristic of his alter-ego, Sethany from IT.
- Casual Kink: Her pitching of a "Fifty Shades of Dildos" sketch (which Mike Trapp shoots down) is a mere passing mention at the beginning of this video.
- Embarrassingly Painful Sunburn: But dont worry, it will turn into a tan.
- Extreme Doormat: She literally cant say no to anyone or anything.
- Serious Business: Suffers from this at the hands of the other cast members when she has the effrontery to sneeze four times.
- Taken for Granite: Freezes into an ice statue at the end of "Why Summer is Women's Winter"
- Rich in Dollars, Poor in Sense: She is unable to conceive of her friends' financial limitations in "Your rich friend who travels all the time".
- The Thing That Would Not Leave: In "The Person At Your Party Who Never Leaves".
- Anything That Moves: Uses sketch pitches as an excuse to kiss and make out with his co-workers.
- Aroused by Their Voice: In The Skinny Bitch Diet Menu, Grant played a soft-and-sensually-spoken "dom-daddy" waiter who had this effect on many viewers of both genders, judging by the comments on the video.
- Celebrity Resemblance: Grant lampshades his resemblance to Keith Habersberger from BuzzFeed on several occasions, including one in which he laments the supposed failure of Lenjamins promise that buying new glasses would make him look just like him. The gag is taken to a new level when Grant and Keith appear in a sketch together.
- Coming-Out Story: He comes out to his fellow cast members, and is confused when they show no reaction. At first, that is.
- Extreme Omnisexual: Already known as bisexual, his proclivities are shown to go even beyond humans as disturbingly shown at the end of this video.

- The Hyena: He's notorious for laughing and breaking character during filming, and has been the loser in two episodes of the "No Laugh Newsroom Challenge".
- The Klutz: Plays this both for comedy and for horror.
- Last Stand: Attempts one to protect his friends and himself from being made into pie. Sadly, it's just a minor annoyance for the giant, who crushes him to death. Good thing that Death Is Cheap in the CollegeHumor universe...

- Tall Poppy Syndrome: Exhibits shades of this in "Why It Sucks When Your Friend Becomes Successful".

- The Barnum: Pretends to be one during her closing speech.Katie: (smiling) "And if you want access to CollegeHumor's secret site, make sure you send your social security number, your credit card information, and your Mother's maiden name in a private message to me."
- Beneath the Mask: She engages in some quite tragic Self-Deprecation in These Sketch Pitches are Too Personal, while denying that shes doing it and insisting that shes just pitching sketches.

- Casanova Wannabe: Zigzagged. She doesn't flirt directly, but she tries to get everyone else to flirt with her.
- Cloud Cuckoolander: Although most of the actors play these kinds of parts, Katie is probably the queen of this trope. For example, she not only doesnt see race, but also pretty much any other distinguishing feature in humans.
- Friendly Neighborhood Vampire: Plays a Shrinking Violet of a vampire who is extremely hesitant to accept Rekha's invitation to enter her apartment.
- Functional Addict: Likes cocaine, but the mountains of it she consumes never seems to have any lasting effect upon her.
- Hipster: She is proud of how little she knows about anything that is popular so that she can claim she has better taste than anyone who likes something popular. Claims that anything popular is 'stupid and bad' and brings up things she knows nothing about (claiming someone else brought them up) so she can brag about how little she knows.

- Berserk Button: Being called a boy by Katie.
- Brutal Honesty: While everyone is directing backhanded compliments against an absent co-worker, he is the first one to be overtly insulting.
- Cannot Spit It Out: After hitting his head, he spends an entire sketch unable to answer a question about who the US president is in 2017 because he has dismissed his first (correct) impulse as too insane to be true.
- Clone by Conversion: He's somehow turned into a doppelganger of Grant during "Is Grant Keith from BuzzFeed?".Trapp: Whoever the fuck this guy is, I've never seen him before in my life!Grant: Trapp, that's a mirror. (Reflection shows that Trapp now looks like Grant)
- It Is Pronounced Tropay: Puts this on as The Guy who Overpronounces Foreign Words. It is telling that even Adam is infuriated by this.
- Last-Name Basis: While most other cast members are on First-Name Basis, he's generally referred to as "Trapp".
- Murder Makes You Crazy: Viewers of "How Tall is Grant?" suggested that this was Trapp's guilt-induced hallucination after murdering Pat Cassels.

- Disney Death: He is murdered, probably by Mike Trapp, in 2015; however, he is later revealed to be Not Quite Dead and returns for more sketches. Or perhaps it's just Death Is Cheap in action.
- Only Sane Man: In Coming out as trans-everything, in which everyone else is a Cloud Cuckoolander.
- Black Hole Sue: The universe bends to his will in Everyones Favorite New Cast Member, to the consternation of Ally.
- Condescending Compassion: In Im Black, Not Poor, he cops a ton of this from his co-workers, as well as from a homeless woman who gives him her food.
- Don't Celebrate Just Yet: He takes this mindset to an absurd extreme in Don't Jinx Anything by Celebrating, even as he moves from strength to strength.
- Dysfunctional Family: So much so that he is compelled to rush around in a protective suit during Thanksgiving dinner to physically disarm the conversational landmines before any major fight breaks out.
- Easily Impressed: Exaggerated by his character, Lenjamin from IT, in The Guy who Overhypes Everything.
- Fake Interactivity: In his closing speech, he pretends to take a message from the audience, responding accordingly:Raphael: And click here to leave a detailed message... uh-huh... what, you what?... you didn't!... I'd-a-done the same thing.
- Gift-Giving Gaffe: Commits an increasingly ridiculous and implausible series of them at Christmas time, making it painfully obvious to his co-workers that the gifts he supposedly bought them are really for himself.

- It's All About Me: She only thinks about fatal tragedies in terms of how they affect her, and only considers previous decades in terms of how cool she could have been in them.
- Casanova Wannabe: As Pat's dysfunctional brother in "The Guy Who Always Talks About Hot Girls".
- Dismissing a Compliment: In "The Guy Who Deflects Compliments".
- Entitled Bastard: Acts as a royally-attired one in "If People Asked Questions Like They Do On Facebook".
- Excuse Me While I Multitask: Continues to relate how he got no sleep last night while fighting off and defeating all the other cast members who are attacking him because of his gall in telling this story.
- Forbidden Fruit: In his case, eating the laundry pods.
