The super in which Samson turns them into a flying cockroach is called Gregor Samson.
Filia also sometimes says "HENSHIIIIN!" when using the attack.
Her aerial heavy punch, Salon Treatment, involves tossing her hair forward in an array of sharp instruments like forks, knives and spikes. One of these sharp instruments is the Lance of Longinus.
Her Updo special and Fenrir Drive super, in which Samson turns into a giant hair maw, happens to be a shout out to one of the Dustloop forum members, who suggested no game with any hair-fighters would be complete without at least one reference to the Pokémon Mawile.
The combination of her eating habits and Samson's appearance on her head bears a similarity to the futakuchi-onna, who in Japanese mythology is a woman with a mouth on the back of her head that's driven to eat and eat.
The bar in the opening of her story mode is a parody of the famous Nighthawks painting, and is named after Madman's Cafe.
Mike Z has described Filia as the game's Ryu-clone. She has Hadoken-motion "projectile" (actually a drill that comes out of the ground some distance away from her, as determined by the strength of the button pressed), Tatsumaki Senpukyaku-motion spinning extended attack that works in air, and Shoryuken-motion uppercut.
One of her attacks involves Samson turning into a donkey and pushing Filia as if he's bucking the opponent, causing a wall bounce in the corner. This may or may not be a reference to Ryu's Jodan Sokuto Geri, commonly known as the Donkey Kick, which also causes a wall bounce in certain situations.
Samson's name comes from the story of Samson, who had superhuman strength so long as he kept certain vows, one of which was to neither cut his hair nor shave his beard.
One of her moves has her shouting "EXCELLENT!" while Vice-Versa throws up the heavy-metal "horns" gesture. During said move, Vice-Versa's eyes briefly turn into Kamina'sshades while Cerebella herself does the "Pierce the Heavens" pose.
She has a close range move (that also reflects projectiles!) where Vice-Versa performs a Finger Gun point. While doing this, the poses of the duo are reminiscent of Jotaro Kujo and Star Platinum.
Cerebella's second alt color is a reference to R. Mika
She also has a Potemkin color palette.
She also has an emerald green outfit similar to one of Tager's alternates — the same palette that lead designer Mike Z uses when playing Tager in BlazBlue.
Another of her palettes has her referencing NiGHTS from Journey of Dreams.
She also has a palette swap with red-and-black clothing, making her look somewhat like Harley Quinn.
During one of her moves she will use Vice-Versa as a pommel horse and shout "Gymkata!"
Peacock's entire character, from her moveset, animations, and design, is a reference to classic cartoons. As mentioned on the main page, she could have been ripped out of an demented Merrie Melodies cartoon.
(vs. Filia): "Maybe she's born with it!"note It's the first part of Maybelline's (a line of hair care products') slogan.
Her Argus System is a reference to the Argus of Greek Mythology. That Argus had a hundred eyes (some of those eyes in his arms). When that Argus died, Hera placed his eyes in the peacock's tail as tribute.
One of her crouching attacks kicks the opponent with the Kuribo's Shoe from Super Mario Bros. 3, complete with the good ol' "HERE-A WE GO!". Its name, Curb Your Shoe, is another part of the allusion.
Her block techniques often have her holding up an actual block of something — from a cinderblock to an L-block.
Peacock's reference palettes include Cable, the Lucky, the Lucky Charms Leprechaun mascot, Cirno, and Hsien-Ko. The Cirno palette is number 9. Also, upon gaining the Skull Heart in her story mode, she says "Who needs wishes? I'm already the strongest there is!" "I'm the strongest!" being one of Cirno's memetic catchphrases....
Speaking of Hsien-ko's Tenrai-Ha, one of the new features added to the game in Squigly's patch is taunts, and to do Peacock's taunt, you have to do the same button input as Tenrai-Ha had in the Darkstalkers games. Successfully pulling one off guarantees that the next level 3 item drop you get is the move.
Another attack is her kicking and missing a football, yelling "Good grief!" when she trips. The alternate line for that technique is "Laces out!"
One attack turns her arm-eyes into blades, the classic visual pun on "looking daggers" at someone. The chances of her also shouting "Like THIIIIIIIIS!" are about one in five.
Keeping with the WFRR theme, one of her win quotes (when defeating Parasoul) is "You're not bad, you're just drawn badly" — riffing on Parasoul's undeniable resemblance to Jessica Rabbit. Yet more Bonus Points for Parasoul having a color palette that gives her Mrs. Rabbit's outfit.
Her jumping Medium Kick, which involves her beartrap mouth, is called "Nice Booby Trap", a line from Eddie Valiant about the bear trap that Jessica Rabbit keeps in a very punny place.
Two of her win quotes are "I never forget a face, but for you, I'll make an exception" and "Either you're dead or my watch has stopped," all while smoking a cigar.
Groucho's not the only Thirties/Forties comedy icon Peacock pays homage to, either. She also quotes at least two of Moe Howard'scatchphrases ("Why, I oughta—" and "Spread out!"). She also references Curley: when selected, her call-out line is "Soitently!"
Her time-out animations seems to be a reference to Daffy Duck being shot by Elmer Fudd.
In her Story Mode, she's awoken from bed by Avery saying "Hey! Listen!"
Unsurprisingly, she can also say "Ain't I a stinka?" and "What a maroon!" when she wins, and "This ain't Albuquerque!" when tagged in. As noted above, "Of course you know, this means war!" is one of her intro lines.
One of her lines when using her c.LP (where she attacks the opponent with a cigar) is "Nyah, see?", imitating classic actor Edward G. Robinson, known primarily for playing gangster roles and was famous for peppering his lines with heavily accented "Yeah!" and "See?".
When she uses her "Lonesome Lenny" super, which prompts her to drop a gigantic bomb, one of her lines is "Fall down, go boom!"
One of the Black Egrets, Molly, has a talking pose where she salutes, closes her eyes and has an open zigzagged mouth, which may remind some people of Wobbuffet.
Ms. Fortune's original outfit seems to be a reference to Makoto (the general appearance) and Lara Croft (the color and the pouches she has on her belt). Since then, her color scheme and hairstyle have changed to stand out from the other characters and be more fitting with the 30's era.
If she uses the super with her head off, however, she turns her hand into a drill and makes a pose like a certain mecha.
Her other super, Feral Edge, has her using her tail as a sword to dive down in similar fashion to Ragna's Belial Edge.
One of her special attacks is done with three repetitions of the same button combination (Quarter-circle forward + Punch), similar to characters like Fei-Long, Karin Kanzuki or Iron Fist. That's not the Shout-Out part, however - these types of characters are known as "Rekka-style" characters. What does Ms. Fortune say if you finish the three-hit special with one of two alternate enders? Either "Wreck-a your face!" or "Wreck-a your shins!"
She announces one of her low attacks by saying, "Tail spin!"
Sometimes when she bowls her head at the opponent, she'll say "Rolling start!"
Valentine's Level 3 Super features the opponent getting seven different kinds of messed up, but said messing up is concealed behind medical screens and red flashes. Very similar to Akuma's Raging Demon attack.
If she loses by timeout, she explodes into a mass of bones as if hit by a Mortal Kombat 3 fatality, down to the multiple skulls and ribcages.
Sometimes when Valentine tags out to Double, she says, "Prepare for trouble!" It's the first line of the Team Rocket mantra from the Pokémon anime. (The next line of that mantra is "Make it double.")
Another one of her moves has her send out Leviathan's tail a long way to bring the opponent to her for a combo setup. Sound familiar? In addition, when using the move, she or Leviathan might say "GET OVER HERE!" or "C'MERE!"
One of Squigly's beta palettes (which was replaced just prior to release because Alex didn't like it) was a reference to Earthworm Jim, including making Leviathan pink and Squigly's head transparent to look more like Earthworm Jim's robot suit.
Her tag-in attack, which involves her coffin shooting up from the ground and her bursting out of it has some similarities to how Rayne enters stages in Bloodrayne: Betrayal (Though there the coffin usually lands from above, not bursting out of the ground). Specifically, the second part where she launches the top half of the coffin at the opponent has similarities to how Rayne can kick the top half of her coffin at opponents at the beginning of a level. The fact that Alex worked as a character designer on that game makes it likely this was intentional.
Big Band is explicitly stated to play like Q "but good".
His jumping HK is a pretty blatant reference's to Q's jumping HK.
Speaking of his taunt, its revised input is Forward, High Punch, Mid Punch, Low Punch, Forward, almost the exact same input as DIO's Space Ripper Stingy Eyes move from the Capcom fighting game.
His level 5 super (taking out the trumpet and playing the Skullgirls theme) causes time to stop like Dio's famous ZA WARUDO move. Doing so lets him pound out a ton of TUBATUBATUBATUBATUBAs in rapid succession until the meter depletes to zero. Or he can just play his trumpet.
When using Super Sonic Jam, Big Band may say, "Aww... HORNCRUSH!!"
He has a chance of saying "Lazy bird." during his airthrow, in another reference to John Coltrane.
Against Mafia members (i.e. Cerebella), he gets the opening quote "You will be prosecuted to the full extent of the jam" — which takes an infamous bit of Engrish from the DonPachi series and fits it into his jazz theme.
One Big Band's losing quotes is "Salt...peanuts". This is a reference to the bebop tune "Salt Peanuts" composed by Dizzy Gillespie.
Big Band's "Beat Extend" is likely a pun on "Heat Extend", Potemkin's anti-air grab move.
Speaking of Potemkin, the Heavy Kick version of Giant Step is functionally similar to Potemkin's Sliding Head attack.
Adding onto the Potemkin connections, his Brass Knuckles and Emergency Stop function basically the same as Potemkin's Hamerfall and Emergency Stop respectively. Brass Knuckles and Hamerfall even share the same charge motion.
While performing a jumping LK, he'll sometimes say "Shake, shake!".
Another achievement is obtained for KOing two characters in the same combo. Its name, of course, is HappyBirthday.
The psychic director of Lab Zero is called Brain Drain.
Early on in Parasoul's story mode, Umbrella had apparently expected to see: "Sonic boobs, pool balls, and KFC Combos" when she came along to see her at work. It helps when you know Parasoul plays like a charge character, which is what Guile and Venom are considered to be as well. Parasoul's playstyle is somewhat reminiscent of Venom, as well.
One of the background characters is a sleeping man in a familiar outfit leaning against a wall next to a sand bag. Said sandbag looks an awful lot like Bonus-Kun from Waku Waku 7.
In Peacock's story mode we meet Hive, a resident of the Anti-Skullgirl Labs, who we can see in the background of the stage as well. Other than her name, her outfit and lavender hair bear a resemblance to Q Bee.
In the tutorial screen there is a drawing of Ms. Fortune's head forming the bottom slime in a slime tower from the Dragon Quest series.
Killing off 2 characters at the same time or dealing a very large amount of damage in one combo will result in legendary 3rd Strike commentator John Dangerous Rockefeller laughing. This itself is also supposedly a shout out to Dan Forden shouting "Toasty!" in Mortal Kombat.
One of the members of Cirque des Cartes, Hubrecht "Hertz" Adelhardt, has an appearance similar to Alex Louis Armstrong. His design is heavily influenced by Arcana Heart's Heart Aino, with pink hair in a heart shape, a red ribbon tied in a bow around the wrist, red suspenders (in place of a red tie), orange pants (in place of an orange skirt), and blue boots (in place of blue shoes). He's likely also a reference to Mr. Heart.
It's worth noting that as far as his color palette relations to Heart go, an in-game image in Cerebella's story shows him with very different colors (as well as different colors for various other troupe members than what is shown in most character art), so it is currently unclear whether or not this will remain as his color palette if he is added into the game. The hair and ribbon remain key to his design.
Visible on the right side of the New Meridian stage is The Kid's hammer, along with a Squirt. They're placed on both sides of a female NPC based on the art director of the very same game, seen here◊. (The three-eyed creature next to them is likely one of Alex "o_8" Ahad's Author Avatars.)
However, his bio lists "notKanji" among his inspirations.
The Medici Tower stage has a billboard for "Wave Motion Emitters" with a picture of a blue fireball above it. The famous Hadouken is sometimes called "Wave Motion Fist" by fans, after its literal translation from Japanese.
One of the characters at the card tables in River King Casino is dressed like Jotaro, as a nod to the encounter with D'Arby during Stardust Crusaders.
One of the NPCs that can appear in the Glass Canopy stage is a young woman in blue and white carrying a purse with a George plushie in it. This character is actually a personification of Sanshee, one of the two companies who are licensed to make Skullgirls merchandise.
Several backers from the Indiegogo campaign can also appear in the background of both the Casino and Glass Canopy, including some popular internet personalities such as Matt and Woolie and Zone-tan. Some of these characters represent prominent people in the competitive Skullgirls community, such as Duckator and Severin; the NPC of the latter in particular later appeared in the Fukua trailer.
The New Meridian Rooftops stage has two billboard for Eighty Sixed, A clothing store whose Twitch channel hosts their weekly stream, and Frootsii, a bakery in California that was the original venue for said stream.
The Under the Bridge stage contains a food van that specializes in salty items; the first item written on the truck is "Salty Cupcakes," the original name of Lab Zero's weekly Twitch stream.
The 2013 holiday patch introduced a new mode called The Typing of the Skullgirls where the player gets a chance to do extra damage with supers by typing in the words that appear on the screen. Two of the phrases that can pop up are "dogs of the ASG"note A reference to a memetic line from House of the Dead 2 and "Suffer like we did!"note referencing both House of the Dead 4 and Lab Zero's tendency to have bad things happen to them. Several other phrases reference various parts of the game and memes created by the community.
The effect that happens during doublesnaps (the action lines and the Skullgirls main theme in the background) was inspired by Japanese player Poccola, who would always add the effect during a doublesnap or a Happy Birthday in Skullgirls videos.
Finishing a match with a Blockbuster causes the background to turn black and display a white line art portrait of the defeated character with an expression of pain on their face. This is a reference to JoJo's Bizarre Adventure: Heritage for the Future, where similar portraits appeared after a character was defeated by a super move.
