History WebVideo / Dimension20

* MouseWorld: Some of the mundane animals that are awakened to the Unsleeping City have their own hidden communities, like a pigeon community village or a cockroach monk monastery inside an old hotdog cart.
* NinjaPirateZombieRobot: Pete is a drug addicted and drug dealing cowboy sorcerer chosen one.

** In ''Showdown at the Stock Exchange'', [[spoiler:Robert Moses]] hits Pete with a Power Word Kill spell, which instantly kills anyone who is below 100 hitpoints. Thankfully, Kingston has revivify prepared.

* PutOnABus: [[spoiler:Rowan is absent at the start of Season 2, with Siobahn playing a new character, as she felt that Rowan's story was completed. She returns after Iga gets captured by Null at Ellis Island.]]

** On a slightly more lighthearted note, Cody's obsession with looking cool and having badass swords bites him in the ass when he gets a fusion of three swords, dubbed Thirsting Blade Dark Excalibur Mega Genesis... and it is ''completely'' unusable. It deals extra necrotic damage and heals him on a Nat 20, but since it weighs more than he does, Cody rolls with disadvantage (meaning he would have to get two Nat 20's to even trigger that effect), has to make a DC 15 athletics check to even swing it, and [[EpicFail he severely wounds himself with it on his first ever attempt to attack with it]]. [[spoiler:As part of his CharacterDevelopment, he takes it apart, selling off the Dark Excalibur and Mega Genesis portions.]]

* AmbiguousSituation: It's unclear if Kingston magic doesn't work outside of New York, or if it specifically doesn't work in [[{{Joisey}} New Jersey]].

--> "It is bigger than Nod, bigger than New York, bigger than anything. Its form is formless, its mass is massless, it extends from here into the deep, dark depths of the dreaming forever."

** Averted with Sofia in Season 2; Dr. Lugash said that due to her having concieved a child with an angel, New York could get obliterated completely and the fetus would still survive.
** [[spoiler:Played straight later in the season when Esther gets kidnapped by Tony. Even then, she's just banished to another plane of existence, so she avoids most of the fight.]]

* MegaCorp: Gladiator in Season 2 has enough influence in New York to do things that would be BeyondTheImpossible in real life, from buying up landmarks and museums to creating humanoid delivery drones.

* NoodleIncident: Kingston and Misty often refer to a mummy that they fought several decades before the campaign started, which Kingston now keeps in an obsidian ankh underneath the salad bowl on the top of his fridge.

* PaintingTheMedium: PlayedForLaughs in Chapter II[[note]]Filmed during the UsefulNotes/COVID19Pandemic over Zoom.[[/note]]. When Sofia casts Silence on Ricky, Zac mutes his microphone so he can't be heard screaming.

** In Season 2, Cody randomly having outbursts and saying "Fuck!" whenever things don't completley go his way.

** On a slightly more lighthearted note, Cody's obsession with looking cool and having badass swords bites him in the ass when he gets a fusion of three swords, dubbed Thirsting Blade Dark Excalibur Mega Genesis... and it is ''completely'' unusuable. It deals extra necrotic damage and heals him on a Nat 20, but since it weighs more than he does, Cody rolls with disadvantage (meaning he would have to get two Nat 20's to even trigger that effect), has to make a DC 15 athletics check to even swing it, and he severely wounds himself with it on his first ever attempt to attack with it. [[spoiler:As part of his CharacterDevelopment, he takes it apart, selling off the Dark Excalibur and Mega Genesis portions.]]

** The haunted subway train in Chapter II is similarly a very obvious dig at several types of annoying subway passengers.

* TraintopBattle: During the Subway Battle in Chapter II, Sofia and a Frankenstein's monster end up atop one of the carriages.

** [[spoiler:And by "severely weakens", Brennan revealed in an interview a few years later that this action HALVED its hitpoinst.]]

* YearInsideHourOutside: Everything in Mentopolis moves at the speed of thought, so what seems like a day for the characters might only be a moment for Elias Hodge. [[spoiler:Which is good, seeing as he was thrown out of an office window in Episode 2.]]

* Emily Axford as Fig Faeth, wood elf / tiefling bard [[spoiler:warlock]]

* TheUnTwist: In the penultimate episode, Murph says that [[spoiler: he thought Vice Principal Goldenhoard was mean so that meant he was a good guy.]]

* ChekhovsGag: In season 2, The Bad Kids find the name of Garthy O'Brien suspicious and figure it to be an anagram. The ultimate solution they come up with is "Night Yoarrbe", which most likely [[ComicallyMissingThePoint isn't a lead whatsoever]], considering "Yoarrbe" (which they later shorten to "Yorb") isn't even [[PerfectlyCromulentWord a real word]]. However, the Hangman takes it extremely seriously as if it was a real and dangerous entity, screaming "SPEAK NOT OF THE NIGHT YORB!" Later, while high, Riz gets the name tattooed on his chest. The Night Yorb then becomes somewhat of an inside joke in the fandom, the joke being that it couldn't possibly mean anything. [[spoiler: However, In the epilogue of the finale, Riz is shirtless and his mom scolds him for getting so many tattoos. When Riz reads his chestpiece back to her, he starts floating in the air as the sky blackens and booms "You have spoken the name of the Night Yorb! An age of darkness forevermore!", turning what was previously day into eternal night. As it turns out, the Night Yorb is a very real and very dangerous entity, possibly being the BigBad of season 3]].

* SurprisinglyRealisticOutcome: Kristen and Fig are dangerously close to being expelled from Augefort in Junior Year; Kristen's reason is a bit outlandish [[spoiler: (she let her god YES! die from lack of faith in him)]] but Fig is in danger of being booted out due to serially skipping the classes intended for her cirriculum as a bard, whish is exactly what would happen if a student skipped classes regulary at an actual high school.

* TheEnemyOfMyEnemy: The great big finale battle ''looks'' like all the Wurst's enemies against the Gunner Channel...until our heroes savvily deploy the evidence they gathered [[spoiler: of UFTP's planned buyout of the Grivarr Worlds. Uncle Bob chummily thanks them for "helping a pal out" and swings around to aim at the UFTP ships.]]

* HomoeroticDream: Lampshaded

* Freddie Wong as Dan Fucks

* Hank Green as The Fix

* ShoutOut: [[ShoutOut/Dimension20 Has its own page.]]

''Dimension 20'' is usually considered alongside ''WebVideo/CriticalRole'' and ''Podcast/TheAdventureZone'' as some of the best-known Actual Play TTRPG shows on the internet.

* {{Balloonacy}}: The party have to climb several balloons from the Macy's Day Parade in order to defeat several monstrous clowns. No, not people in makeup, but real clowns.

* CelebrityParadox: PlayedForLaughs when, after a particularly intense battle, members of the Dream Team plug Series/AdamRuinsEverything to various citizens of New York; all of the party members in this season, except for Ally, have appeared on that show at some point, with Emily and Brian being primary recurring characters.

* RagtagBunchOfMisfits: The main cast is the very definition of a motley crew, with the [[OnlySaneMan eternally frustrated captain]] [[spoiler: possessed by a runaway prince brain parasite]], a people-pleasing rogue android, a meathead clone trooper, a happy-go-lucky psychic alien roped into a multi-level marketing scheme, an unlucky cyborg who is literally renting his own right to live by a miserly insurance company and [[TheLastOfTheseIsNotLikeTheOthers a businesswoman]].

[[/folder]]

[[folder: ''Fantasy High: Junior Year'']]
* ActionPrologue: The season begins immediately with combat as the Bad Kids face down against the Night Yorb and its minions.
* GodNeedsPrayersBadly: Kristen's habit of thoughtlessly abandoning her gods comes to bite her as it's revealed that Yes! died due to her neglect and Cassandra's power is desperately waning.
* IToldYouSo: After the Bad Kids discover that saying the Night Yorb's name heals it, the Hangman admonishes them saying that he and the Hangvan were pretty clear about not speaking of the Night Yorb.
* PunctuatedPounding: Fabian repeatedly stabbing the last Yorbie:
-->'''Fabian''': You ''didn't''... ''have''... to ''do it''! You ''could''... have ''had''... an ''ice cream''!
* RememberTheNewGuy: Since the Bad Kids have ostensibly been pursuing the Night Yorb all summer they have had met a number of characters off sceen that the audience hasn't seen before, but the cast reacts like they were major [=NPCs=] that they have inside jokes and meaningful relationships with.
* SerialEscalation: An inversion. The first season involved the Bad Kids working against a conspiracy in their hometown and thwarting an evil overlord's return to power. The second had them crossing the world fighting pirates and evil empires and culminating in the unmaking an evil lich-god. Their off-screen adventures after the second season reach their climax in the first episode of this season where they prevent a planetary apocalypse. And the primary threat of this season is... junior year of high school. It's also played for drama because the Bad Kids are very clearly frustrated that after several adventures of increasing scope and importance, they have to deal with the mundanity of grades and school government.
* SparingTheFinalMook: Subverted with the Yorbies. Fabian ''tries'' to spare the last one, and even offers him a bite of his ice cream sandwich. Unfortunately the Yorbie proves to be TooDumbToLive and throws the ice cream in Fabian's face.
* SurprisinglyRealisticOutcome: Kristen and Fig are dangerously close to being expelled from Augefort; Kristen's reason is a bit outlandish (she let her god YES! die from lack of faith in him) but Fig is in danger of being booted out due to serially skipping the classes intended for her cirriculum as a bard, whish is exactly what would happen if a student skipped classes regulary at an actual high school.
* TimeSkip: ''Sophomore Year'' ended with the Bad Kids preparing the pursue the Night Yorb before it can destroy the world of Spyre. The first episode of ''Junior Year'' is set up as though it were the finale to an unseen (and unproduced) Night Yorb season of ''Dimension 20''.
* WakeUpGoToSchoolSaveTheWorld: A version where the 'school' part is played for drama. After two seasons the Bad Kids are hardened adventurers who've saved the world several times over, but that skillset doesn't help them deal with increasing courseloads, financial responsibilities, and generally having to deal with all sorts of demands and duties that can't be solved by fighting them.

* CovertGroupWithMundaneFront: To the outside world, the Clinton Hill Chantry, New York's first line of defense is, according to Ricky's sister, "some thing at Clinton Hill."

--> "It is bigger than Nod, bigger than New York, bigger than anything. Its form is formless, its mass is massless, it extends from here into the deep, dark depths of the dreaming forever.

* RunningGag: Because Sofia lives in Staten Island (which is a ferry ride away from most of New York), despite the fact that she's happy to have guests over, almost no one takes her up on it.

* AmbiguouslyHuman: [[Music/StephenSondheim Stephen]] [[ItMakesSenseInContext Sondheim]]. He appears to be just a normal human at first, but he's at least a 10th-level Bard, knows of the Unsleeping City, [[spoiler:recognizes Rowan after she's reborn from Misty, and in season 2, somehow ''spontaneously reconstitutes himself'' to get the Dream Team out of Nod as Null is tearing it apart.]]

* CovertGroupWithMundaneFront: To the outside world, the defence of New York is, according to Ricky's sister, "some thing at Clinton Hill."

* EldritchAbomination: The clown enemies from the balloon fight are minor examples; their weapons are literally balloon swords and bows, but they deal very real damage of a type Brennan home-brewed called "chaos damage" which was implied to have effects beyond simply hurting. Alas, the fight was over too quickly to find out. But they did almost kill Santa Claus.

* SurprisinglyRealisticOutcome: Kristen and Fig are dangerously close to being expelled from Augefort; Kristen's reason is a bit outlandish (she let her god YES! die from lack of fatih in him) but Fig is in danger of being booted out due to serially skipping the classes intended for her cirriculum as a bard, whish is exactly what would happen if a student skipped classes regulary at an actual high school.

* FlintstoneTheming: Every part of the setting, including character names, place names, historical events, religious beliefs, and cosmology, involves some kind of food-related pun, which range from the [[StealthPun subtle]] to the hilariously obvious.

* Jasper William Cartwright as Thorn Vale
* Erika Ishii as Ava
* Brennan Lee Mulligan as Tula
* Isabella Roland as Lila
* Rashawn Nadine Scott as Viola
* Siobhan Thompson as Jaysohn

* Lou Wilson as Fabian Seacaster, half-elf fighter

* Zac Oyama as Gorgug Thistlespring, half-orc barbarian
* Emily Axford as Fig Faeth, wood elf / tiefling bard

A tabletop adventure anthology show on the comedy streaming site, ''Creator/{{Dropout}}'', hosted by [[Creator/BrennanLeeMulligan Brennan Lee Mulligan]] and a main cast of former ''College Humor'' alumni, [[Podcast/NotAnotherDnDPodcast Emily Axford]], Ally Beardsley, [[Podcast/NotAnotherDnDPodcast Brian Murphy]], Zac Oyama, Siobhan Thompson, and Lou Wilson, known as ''The Intrepid Heroes''. Besides starring mostly people with comedy and improv backgrounds, ''Dimension 20'' also decidedly focuses on shorter adventures than most tabletop actual-plays. Their seasons always keep it around 20 episodes and usually feature a new setting or characters, though sequel seasons for both ''Fantasy High'' and ''The Unsleeping City'' and a prequel season for “A Crown of Candy” have been produced, as well as an announced sequel to Dungeons and Drag Queens.
