Queen Chrysalis

The queen of the changelings, Chrysalis, is the primary antagonist featured in the second season finale and in the Friendship is Magic IDW comics' first four-issue story arc The Return of Queen Chrysalis. She is a shapeshifter who appears as Princess Cadance and takes her place in order to invade Canterlot by rendering her fiancé, Shining Armor, unable to perform his protection spell over the city by weakening him with her magic, so she and her subjects could take over Equestria.

Development
Meghan McCarthy, Rob Renzetti, and Lauren Faust came up with Chrysalis together. While on-screen the character is only introduced as "queen of the changelings", she is named Chrysalis in the episode's script and iTunes and Netflix summaries, as well as in merchandise, including trading cards and the comic book series. The episode's script describes her as "QUEEN CHRYSALIS, a GANGLY BLACK PEGACORN with a gnarled black horn." She and the other changelings were designed by Rebecca Dart, the main character designer for season two. Rebecca was inspired by the work of manga artists Junko Mizuno and Hideshi Hino after reading the name "Chrysalis", and "figured she should be insect-like."

Impersonating Princess Cadance
Queen Chrysalis first appears impersonating Princess Cadance in A Canterlot Wedding - Part 1, looking and sounding like her, but acting different enough to raise Twilight Sparkle's suspicions, though Twilight's friends, Shining Armor and Princess Celestia, don't buy Twilight's story. Chrysalis walks on-screen right after Twilight's flashback and description of her memory of Cadance as a beautiful, loving, and kind pony, from when she foal-sat Twilight. Chrysalis doesn't recognize Twilight, which unsettles her and raises her suspicions. When Chrysalis comes to check the menu for the wedding, she insists on being called "Princess Mi Amore Cadenza", and even though she politely compliments Applejack on her baking, she throws away the food Applejack offers her, again raising the ire of Twilight. When she comes to inspect the dresses Rarity is sewing for the wedding, she sneers at her bridesmaids who praise the dresses and asks Rarity to make the dresses a different color. She sarcastically remarks on Pinkie Pie's party plans that they're "perfect... if you were celebrating a six-year-old's birthday party." Twilight sums up Chrysalis's behavior to her friends as "an awful pony who doesn't deserve to even know Shining Armor let alone marry him." When Twilight tries to discuss the matter with Shining Armor, Chrysalis interrupts them before Twilight has a chance to say anything; Twilight comments that "she sure has a way of sneaking up on people." Chrysalis asks Shining Armor to go into the other room, where she casts a spell on him that makes his eyes roll. Twilight spies on them through the door and runs out after seeing Chrysalis cast the spell.

At the wedding rehearsal, Twilight accuses Chrysalis of being evil and levies some accusations on her. Chrysalis tears up and runs away, and Shining Armor confronts Twilight and contradicts her accusations, saying "Cadance" is using her magic to heal the migraines he receives from his protection spell. All the ponies leave the room, and after a short reprise of B.B.B.F.F. Chrysalis returns and stomps on the figure of Twilight that's left over from the song. At first she looks down at Twilight with a compassionate face, but then her eyes glow green and engulf Twilight in green flames that sink with her into the ground down to the caves beneath Canterlot.

The next episode, A Canterlot Wedding - Part 2, begins with Chrysalis, still under the guise of Cadance, taunting Twilight through apparitions in an underground cavern's crystals, and telling her that she's using Shining Armor for her own benefit. Twilight shatters the crystals and uncovers a path to the real Cadance, also imprisoned by the changeling queen. A song sequence follows featuring Chrysalis and Cadance singing about the wedding. After outwitting Chrysalis's three bridesmaids who were guarding the cave, Cadance and Twilight manage to confront Chrysalis right before Princess Celestia weds her to Shining Armor.

Queen of the changelings
Princess Cadance proclaims that the impostor is a changeling, a creature that takes the form of those that are loved and gains power by feeding off the love for them. After that, the imposter transforms and introduces herself as queen of the changelings, who is named Chrysalis in the episode's script but not on-screen. She keeps Cadance at bay by threatening to send her back to the caves, and explains that she's been feeding on Shining Armor's love for Cadance, which weakens his protection spell that keeps the changelings out of Canterlot. Princess Celestia confronts her and attacks her with a beam from her horn, but Chrysalis fires back and, thanks to the power of Shining Armor's love, overpowers Celestia and knocks her to the ground, much to the surprise of everyone, including herself. Celestia weakly urges Twilight and her friends to get the Elements of Harmony and use them to defeat the queen.

The changelings break through the magical barrier protecting Canterlot and capture Twilight and her friends, bringing them back to the wedding hall, where Celestia finds herself encased in a chrysalis hanging from the ceiling. The queen sends her subjects to feed, and sings a reprise of This Day Aria, which allows Twilight to free Cadance when Chrysalis is distracted. Cadance's magic breaks the spell over Shining Armor, and gives him strength. The Queen mocks the sentiment, but quickly finds that Shining Armor's spell repels her and all of the changelings out of Canterlot, flying into the distance.

Physical appearance
Queen Chrysalis spends the entirety of A Canterlot Wedding - Part 1 and the beginning of Part 2 disguised as Princess Cadance, with her eyes occasionally flashing green and her magic glowing green instead of Cadance's blue. Once she is confronted by the real Cadance, she transforms into a pony-like creature with a twisted unicorn horn, a pair of tattered insectoid wings, and stands as tall as Princess Celestia. In addition, she has a sharp pair of fangs and dark green eyes with elongated oval pupils. She has a teal mane and tail, blue-green chitinous plating over her midsection, and she wears a small, black crown tipped with blue orbs. Her voice has a distorted echoed quality, as if two voices are speaking slightly out of sync. Her legs, mane, and tail are full of holes, and her limbs and torso are very slender. Like other non-pony characters, she has no cutie mark. Her wings, full of holes like her other body parts, end in sharp points rather then curves (like those of actual insects); when they flap, they generate a buzzing sound.

Depiction in comics
In the IDW comics, Queen Chrysalis is the main antagonist throughout the Friendship is Magic series' first four-issue story arc, which takes place after the second season of the show. Her name is established to be Queen Chrysalis in the story arc's subtitle The Return of Queen Chrysalis and when it is mentioned by Fluttershy in Issue #1.

In Issue #1, the changelings take over Ponyville by imprisoning all its inhabitants except the Mane Six in cocoons. The Mane Six defeat them and rescue all the ponies except the Cutie Mark Crusaders, whom Chrysalis has imprisoned in her kingdom using disguised animals. Chrysalis gives the Mane Six three days to go to the Changeling Kingdom. Chrysalis begins to tire of the rambunctious Cutie Mark Crusaders, and wishes for the Mane Six to retrieve them quickly before she loses her mind.

In Issue #2, the Mane Six set off to rescue the Cutie Mark Crusaders from the Changeling Kingdom. Chrysalis sends changelings to cause a cave-in that separates the ponies into pairs, and changelings imitate the ponies to make the friends argue among themselves. Chrysalis is amused by this, although she is still annoyed by the Cutie Mark Crusaders.

In Issue #3, a flashback reveals that when Chrysalis survives the fall after she was blasted away from Canterlot in A Canterlot Wedding - Part 2, she is weakened from either the fall or Shining Armor and Cadance's attack, but she and her minions recover their strength by feeding off the love of the catlike residents of the town they landed in, transforming the town into a temporary base. Still not powerful enough to invade Equestria again, she decides to absorb Twilight's magic when the Secretariat Comet flies by.

In the present, Chrysalis reveals her plans to destroy Twilight after draining her magic and have her changelings feast on the others when their emotions are running high. The ponies get back together after escaping vicious predators, but Chrysalis claims that seeing them turn against each other for a while was merely an entertaining bonus.

In Issue #4, the Mane Six reach Chrysalis's castle, and while Twilight fights Chrysalis, her changelings imprison the other five. After witnessing Twilight's power, Chrysalis decides to make Twilight her pupil instead of draining her magic. When Chrysalis threatens to drain Twilight's friends, she accepts, only for Chrysalis to reveal her intent to have Twilight drain their love after she drains Twilight's love. However, when the comet flies by, Twilight is powered up. She rejects Chrysalis's offer and, after a long smackdown, defeats her. Pinkie Pie imprisons Chrysalis and her changeling servants in the castle. Pinkie sets up a replica of herself, which endlessly asks the changelings riddles and sings a never-ending song, just to annoy them. The changeling servants at least make an effort to answer her riddles, while Chrysalis just grumbles. Her wings appear damaged and her horn seems to be broken in two with a bandage holding it together. Twilight says Chrysalis won't be able to break out "for a while".

In Issue #10, one of the attractions at the Summer Wrap Up Festival is a head in the hole board of Chrysalis and Discord, and Twilight is shown with her head in the hole for Chrysalis.

Issue #13 has a cover involving an Issue #4 page 1 Chrysalis logo.

An alternate, cheerful version of Chrysalis appears on cover A of issue #19. She doesn't have holes in her horn and legs, has a pair of butterfly wings and a pony-like mane and tail, and is wearing glasses.
