• Actor Allusion / Role Association: Most episodes contained role switcheroos and otherwise at first. It started off with Ritsu meeting Kyubey and Mio meeting Homura. Then Azusa met Madoka, Cul met Sayaka, Kyoko spoke in Litchi's voice, Mio spoke in Seraphim's voice again, Gumi danced to "nyan nyan", Mami is seen with the infamous Navi, then she and Luka get their voices switched to Mifuyu and Satsuki respectively* while Yutaka wore a Nia wig, Chariot ran into Cul and Sayaka, Mio finally meets Noel... And Azusa gets mixed up.

    Noel: (to Mio) Have we met before?
    Mio: Probably...

  • After Show: This is an attempt to do CODE RED without an unsolved case file.
  • All-CGI Cartoon: Save for a few video clips, the filler series is made with Miku Miku Dance (and sometimes with Garry's Mod and/or Adobe Flash). That WAS a CODE RED spoiler.
  • All-Loving Hero: ep16 - "She never loved me, why should anyone—?" *Kshzzzt!* [[Madoka does! She thinks everything's going to be fine!]]
  • all lowercase letters: The episode titles, except for character names.
  • April Fools' Day: ep04 had voice actress switcheroos, and the closed captions states the onscreen characters speaking the lines heard, before the names of the proper characters who their lines belonged to were listed later.
  • Author Appeal: For example, four episodes had characters winking at the camera just like in CODE RED. Three of them were allied or associated with the subject or the #SK09 case file - Mio, who had "exposed her backside" just like the #SK09 subject, Gumi, who is a friend/ally of the subject, and Miku, the subject herself - though the other case, Mami Tomoe, stems from what a character does as part of a special attack in her show.
  • Back from the Dead / : Several certain characters due to the Net Persona's influence since inhibitor filler. However, in Op/Res, it is classified as Resurrected For A Job, and that's just how these mashup crossovers work anyway.
  • Bag of Holding: Homura seems to be able to carry a Portal turret around and hide it until necessary.
  • Big "WHAT?!": Ritsu in ep01
  • The Blade Always Lands Pointy End In: Occurs with Engineer's thrown wrenches in ep29 and ep30. Taken to an extreme with the Southern Hospitality, which sticks into the slashed Inhibitor #2 and doesn't get deflected off the demonic(?) force field surrounding it.
  • Brick Joke: ep24b ends the one set up in CODE RED Dec 25 2010 and has Neru try to listen to "Jolly Old St. Nicholas", a song in which one version's lyrics have a Nellie who "thinks dolls are folly".
  • The Bus Came Back: Both Scouts are seen in footage from a meeting in inhibitor filler ep32, set a long time after Op/Res ep 2. This implies that regular Scout is back on duty, maybe alongside female Scout.
  • Came Back Wrong: In ep27, despite everything being deleted, Vanellope only barely managed to get herself back from the recycle bin... without half the textures on her face and leggings. Spy gave her the extra life she needed outside of her game.
  • The Cameo: There have been a few by certain characters, especially those who appeared in CODE RED or as cosplay characters in the Payback vlogs (including the unreleased episodes), mainly based on voice actor references/connections between characters.
  • Christmas Rushed:
    • ep11 with Pyro making the Morse code Team Fortress 2 website post.
    • ep24b was released within the last hour of Christmas 2012 according to Pacific time.
  • Crossover
  • Death Glare: Homura gives a few in both "can't be happening" episodes (ep01 and ep09) as well as ep16.
  • Decoy Getaway: Spy escaped a death with his Dead Ringer across episodes 26 and 27. It was against an otherwise lethal electric explosive headshot; the fake body that was dropped was assumed to be appropriately headless and gushed out a spray of blood... even onto Spy's suit, imperceptibly.
  • Deflector Shields: In 2013, inhibitor #2 was slashed, leaving a demonic(?) green force field that negates all repair attempts, only glows upon contact, and throws unwitting repairers across the room if they directly use a wrench on it instead of throwing it.
  • Despair Event Horizon: Somebody - The fugitive user - seems to have crossed it; since ep16, the mental inhibitors use "Get Free" by The Vines to accuse Yoko, Dead Master, and (Yutaka dressed up as) Nia.
  • Development Gag: Hinted in ep24c, where Noel asks, "Have we met before?", and Mio replies, "Probably..." Mio was briefly overtaken by Noel's personality in the CODE RED finale, set in 2011, due to Payback influence from later in 2011.
  • Distaff Counterpart: Female Scout in ep27
  • Doppelgänger Crossover: Kicks off this series.
  • Dying to Be Replaced: Scout is incapacitated in ep30 to be replaced by Female Scout.
  • Easter Egg: ep05 contains one.
  • Episode 0: The Beginning: Two videos have been retroactively named inhibitor filler episodes (-2 and -1), and still contain four words in the title.
  • Everything's Better with Penguins: The basis for ep05. Or is it?
  • Fairy Companion: ep05's easter egg and ep16 show that Navi may be Mami's companion, and is allegedly filled with an Incendiary Exponent from being targeted with hatred for so long. Then again, the Net persona could be pulling a Draco in Leather Pants with this.
  • Faking The Dead / Faux Death: It becomes evident in ep27 that Spy used his Dead Ringer watch to survive having his head blown off in filler ep26. However, now he has to live with blood on his suit.
  • Filler
  • Foreshadowing / Accidentally Accurate: ep07, "are we dealing with...?", somehow predicted a few things that occur or cosplay characters that appear in Payback: the Otafest vlogs season 2.
  • Funny Background Event: In ep04, Charlotte, holding one of Mami's rifles, soars past Mami and Mio while they discuss the Calling Your Attacks trope.
  • Girl with Psycho Weapon: Sayaka briefly revs up a chainsaw due to a Lollipop Chainsaw double voice actress reference (The hero in LC was voiced by different actresses in separate Japanese consoles)
  • Girlish Pigtails
  • Hair Decorations: For ep03, having Azusa without her cat ears would just make her seem out of place compared to the other three characters there. Madoka has ribbons, Sayaka has hair clips, and Cul has her ponytail loop and headset.
  • Hair Flip: Someone does this just offscreen in the Easter egg episode. It's Homura.
  • Hey, It's That Voice!: On videos with voice actress references, it's a video tag.
  • High-Pressure Blood: In ep26, blood is heard gushing out of Spy after he suffers a headshot. This death is ultimately faked as Spy appears in ep27... with the resulting bloodstains on his suit.
  • Hoist by His Own Petard: In ep30, Scout is incapacitated by his own Flying Guillotine cleaver... by an alleged psychopath who loves them. Rena thus gains possession of a Hyperspace Arsenal of Flying Guillotines.
  • Hold Your Hippogriffs: In ep17:

    Squid Girl: Hold your seahorses, will you?

  • Idiosyncratic Episode Naming
    • Each installment has four words in the title that are lowercase except for names.
    • ep08, "no, Mio's not herself", also alludes to Kore wa Zombie desu ka?'s episode naming style: as a response to the interrogative title of that series.
    • All occurrences of the word "fear" in inhibitor filler got capitalized and turned upside down on YouTube for each new episode containing the word. They were restored to their own titles when the episodes became unlisted and merged.
  • Improbably Female Cast
  • Inspired By: Payback influence and regular Otafest influence also occurs here.
  • Instant Mystery, Just Delete Scene: Because of a recent drive wipe, ep26 is fragmented to the point where we only hear Spy having his head blown off and a certain electric rifle destroying another inhibitor. Then again, this electric rifle was last heard in CODE RED chapter 5.
  • Interface Spoiler: Is there any wonder why [[Madoka's scenes have a white background?]] And ep16 ended how it did? And ep22 begins how it does?
  • Involuntary Shapeshifter: Vanellope while she's outside of her game due to external forces.
  • Knight of Cerebus: Rena's brutal attack on Scout with two cleavers causes Opposition/Resurrection.
  • Lost in Transmission: ep26 is presented in this manner because it consists of material only barely recovered after the drive wipe (plus some newly filmed scenes).
  • Meido: In ep16, Rena and Tsuruya are in these costumes beside Maid Gunner. The latter is tapping her railgun against the music shuffle box to try to switch off a mashup of An Accent Beyond and Renai Circulation (the latter of which has been associated with maid cosplayers in Payback: the Otafest vlogs).
  • Mentor Ship Tease: in ep02a.
  • Mime and Music-Only Episode: ep24a "those aren't leg warmers".
  • Mind Screw: "what's inside Pyro's mind" (ep15), based on a memetic fad and events in chapter 11 of the CODE RED novel.
  • Mood Whiplash: ep28 has Madoka and Homura hearing from the fugitive, who's implying there are seven people who want him dead. Then it cuts to Kyoko, in Litchi's voice, moping about her shoulders hurting.
  • More Dakka: ep02 applies Engineer's advice to Mami's use of rifles, using a voiceover from "Meet the Engineer".
  • Mythology Gag: In ep16, Dead Master is seen with glasses. This comes from her appearance in the 2012 anime as well as a crazy plan in Payback season 2 stemming from it, though these admittedly look more like Yomi Takanashi's glasses.
  • Offscreen Teleportation: Occurs in ep02 and ep30 with Mami's gun.
  • Ominous Visual Glitch: In addition to corruption via inhibitors, Vanellope causes the whole scene around her to pixelate in inhibitor filler ep27 when she glitches.
  • The Oner: Used in ep09 and ep19.
  • Parasol of Prettiness:
  • Perspective Reversal: Compare ep01 "this can't be happening" with ep09 "really can't be happening".
  • Plot-Relevant Age-Up: Vanellope shows up in ep24b and ep27, and Op/Res. However, she appears as a teenager, as in definitely older than nine in Wreck-It Ralph. This becomes subverted for Op/Res as she appears in her super deformed height.
  • Portent of Doom: The Death Star II solar eclipse is featured in ep06 because an alleged psychopath is present.
  • Post Script Season
  • Prehensile Hair: In ep21, Miku uses her ponytail to grab a green onion missile (like that in CODE RED and the SK09 case file), but it goes haywire (reactivates) and drags her along. She then uses her ponytail to catch a belated birthday present, which has not yet been revealed.
  • The Present Day with a Twenty Minutes into the Future vibe.
  • Production Throwback: The looped Sega scream from a NiGHTS Into Dreams commercial is heard in ep16, after being featured in the WTPF? series and the YTP ss07 Edition! series.
  • Punny Name / Stealth Pun: A few plays on words:
    • ep18: "august 4 total corruption" [[It was an "August for total corruption" of the user's mind, and a "fatal decision" attempt happened on August 4th, 2012.]]
    • ep22: "unclear and persistent dangers" [[Based on the phrase "clear and present danger".]]
    • ep24b: "delayed minute holiday attempt" Other than being delayed to the last hour of Christmas 2012, [[this episode is just under a minute long, and the word "minute" also means small.]]
  • Reality Subtext:
    • ep01 was released one day after Madoka Magica began its home release in North America, owing to the dub's Actress Allusions to KOn.
    • ep09 was released one day after Niconico's broadcast of episode 12's dub. Reality sure is corrupted.
    • ep11 has Pyro making the Morse code Team Fortress 2 website post. Of course, it was rushed.
    • ep12, ep14, ep17, ep17a, ep19, ep21, ep24a, ep24b, ep25, and ep31 were made because "The point is, yesterday (or a recent day) was [a character's or a voice actress's] birthday". -- Gumi, Tsumugi Kotobuki, Christine Marie Cabanos, Kari Wahlgren, Ritsu Tainaka, Miku, Cul, Noel Vermillion (who has a Meaningful Name), Mio Akiyama, Ayana Taketatsu (per her character Azusa Nakano).
    • In ep16, Luka's statement, "She's doing just fine," refers to daily Miku concerts in July-Sept 2012.
    • Also in ep16, Yoko covers her skull-shaped hair clip with her hand at first. This has to do with a crazy plan executed in an unreleased Payback: the Otafest vlogs season 2 episode, as well as the newscast that inspired the plan.
    • In ep16 and Op/Res ep 2, the maids' LhS's playing from the white music box reference those performed by maids at Otafest in the episodes' respective release years.
    • ep27 has Soldier, being a jerk, selfishly steal Demoman's prized Hustler's Hallmark. A scammer manipulated superslinger2007 and conned him out of that hat in mid-February 2013.
    • ep28 was released on the morning of the day the first Madoka Magica film was screened in Canadian theatres.
  • Robot Me: Two Mecha-Engineers— one official, one fan-made— have appeared in an inhibitor filler short.
  • Rollerblade Good: The things above Chariot's wheels aren't leg warmers, Cul.
  • Sacrificial Lamb: Scout gets incapped in inhibitor filler ep30, part of the prelude to Op/Res.
  • Scenery Gorn: The first thing viewers see in ep 25/26 is one of the inhibitor machines with a glowing slash and smoke pouring out of it.
  • Schedule Slip
    • ep20 is set in and is based on a webstream event in late August 2012, but hasn't been made yet.
    • ep21 was meant to be delayed to a Sept. 3, 2012 release from Aug. 31. However, it was released on Sept. 16-17 instead.
    • ep23 was meant to be a Halloween Episode featuring witches of unconventional definition. However, it hasn't been remade due to the drive wipe.
    • ep24b is named "delayed minute holiday attempt" for a few reasons, including this.
    • ep33, a short unofficial Flanderization-based spoof featuring a Dalek and a Cyberman in reference to Doctor Who 50th, was announced with a delay. It was finally remade as a flashback in Opposition/Resurrection episode 3.
  • Self Guarding Phlebotinum: Whoever slashed inhibitor #2 has turned it into this.
  • Serendipity Writes The Plot: Available MMD models, accessibility to clips, and situations such as the drive wipe in Feb. 2013 can influence storylines. This led to the events stated at Instant Mystery, Just Delete Scene and Came Back Wrong above.
  • Shoe Phone: In ep30, Engineer talks into a comm device in his build PDA, which he had since the CODE RED finale epilogue.
  • Shout-Out: ep24a ends with Victini chasing Chariot because both of them are connected with the use of macarons.
  • Sickly Green Glow: The force field surrounding inhibitor #2 when it blares.
  • Sour Supporter: Homura, who overheard the fugitive declaring there are people wanting him dead.

    Homura: What do you mean?

  • Spiritual Successor: To "12 days, 12 drops" in Dec. 2011, which consisted of mostly random short sketches.
  • Standard Female Grab Area: Mio and Homura are seen grabbing each other by the shoulder a few times.
  • Stealth Pun / Meaningful Name: Just had to put [[Noel Vermillion in a Christmas episode, did you? Then again, it was her birthday.]]
  • Suddenly Voiced / Vocal Dissonance: Charlotte the witch in the Easter egg episode. Here, she will remain voiced by "Tiny Weapons Guy", a Heavy soundpack by Benjamoose, for Op/Res episode 3 despite recent events.
  • Surprisingly Good English: Luka in ep16 just before the inhibitors make her speak in Satsuki's voice in Japanese.
  • Talking To Herself: Azusa to Madoka in ep03, Haruhi(?) to Dokuro(?), Yui(?) to Mikuru(?) in ep04, Ritsu to Kyubey in ep07, Madoka to Azusa and Squid Girl in ep17, Kagami to Celty and Tsuruya in ep17a, Cream to Tsukasa in ep16, Noel to Mio in ep24b and ep24c.
  • This Is a Work of Fiction: Used for ep 26-30, the prelude to Op/Res.
  • Time Crash: A minor one occurred in ep09 as Homura temporarily found herself without her shield and with a pink ribbon. Apparently "the Net Persona [was] mucking about with reality again", but it wouldn't be the only time- cue Op/Res ep 3.
  • Visual Pun: For ep05, the Easter egg is the penguin's egg.
  • Voices Are Mental
  • Walking Wasteland: In ep27, the Tux item obtained by Soldier caused the drive wipe and left Vanellope in a half-broken form without some of her textures. It's implied Recycle Bins have been scattered.
  • Warp Whistle / Random Teleportation: The glitchy Tux penguin used by the jerk Soldier.
  • What Could Have Been
    • Mami's eventual use of "Tiro Finale" before the Mid-Season Twist / Late Arrival Spoiler in her series allows Engineer to avoid telling her off in ep02a with "You should have brought more gun, ma'am".
    • Madoka was to perform Pyro's guitar riff taunt on Azusa's guitar in ep03; this made no sense. Cul was to wear a long blonde wig that invokes Kagari Izuriha's appearance, though this was made for ep24a as Cul is seen with the related blonde-haired character named Chariot. Azusa also wasn't going to have her cat eared headband (see Hair Decorations above).
    • If not for the delay, the Easter Egg episode would have been named "four-eight-twelve? no.".
    • ep08 was meant to be exclusive to Payback: the Otafest vlogs season 2 day 2, before that series was placed on The Shelf of Movie Languishment and cancelled.
  • What the Hell, Hero?: Said mostly by Kyoko in the Easter egg episode and Op/Res ep 1.
  • White Void Room: And its black void version, as well as several different colors in the April Fools' Day episode (ep04) and the Pyro-based episode (ep15).
  • You Never Asked: Why else in ep06 would Kyubey not say he likes Disturbed? (Suspiciously Apropos Music)
  • You Have Got to Be Kidding Me!: In the Easter egg episode.

    Kyoko, ep05E (Easter Egg episode): Huh? You gotta be kidding!

  • Your Size May Vary: Kyubey seems bigger than he should be, though it is due to the model size.


* The sole reason why Mami remains speaking Japanese in Op/Res unlike the rest of the magical girls.
