Queen Chrysalis (Friendship is Magic)

Queen Chrysalis is the former queen of the Changeling Empire and one of the most fearsome enemies to have ever threatened Equestria.

Returning menace
Eventually, Chrysalis' forces captured and replaced Celestia,, Cadance, Shining Armor, the Mane Six, and Spike, with orders to collect the love of the ponies for them and share it with the rest of the hive. However, Chrysalis saw no threat in Twilight's student, who recruited , , and the reformed Changeling Thorax to help her rescue the captives. Chrysalis was initially amused by this attempt, but was caught off guard when Thorax shared his love as she attempted to drain it, causing him to transform. Many of the other Changelings soon followed his example, and Chrysalis found her enemies freed and her former subjects no longer obedient to her will. Starlight attempted to convince Chrysalis to abandon her path of conquest and join her people in their new way of life. Chrysalis rejected this offer and fled, swearing vengeance on Starlight Glimmer.

Eventually, Chrysalis hit upon a plan to use the Elements of Harmony to enslave the Ponies in order to create a new hive for herself. To that end, she took on the form of a photographer and took pictures of each of the Mane Six, as well as stealing a hair from each of them. Using these ingredients, she enacted a spell that created evil duplicates of them, hoping that they would be able to wield the Elements in her service. However, the "Mean Six" proved treacherous, attempting to take the Elements for themselves, and Chrysalis was nearly defeated by Mean Twilight Sparkle. The Tree of Harmony destroyed the false ponies, however, and Chrysalis departed, convinced that servants were of no use to her.

Legion of doom
Chrysalis eventually ended up alone in an isolated forest, her mental state decayed to the point where she addressed pieces of wood with Changeling faces carved on them as though they were alive. She was unexpectedly teleported from this place to an unknown location, where she encountered and Cozy Glow who had similarly been brought there. When appeared, Chrysalis briefly believed him responsible for gathering them, only for the true culprit to appear and announce himself as. Chrysalis recognized the legendary tyrant, but was also aware of his defeat at the hooves of Gusty the Great, for which she mocked him. Despite this, she bowed to his wishes to try and form an alliance with the other villains, especially after King Sombra's solo attempt to take over Equestria ended with his demise.

Imperious as ever, Chrysalis chafed at Grogar's delay in taking action, while her other two "allies" proved more annoying than anything else. After their disagreements came to a head, Grogar ordered the trio to retrieve his Bewitching Bell from Mount Everhoof, where Gusty had hidden it after stealing it from him. Chrysalis attempted to scale the mountain herself, but ultimately realized she needed the others, saving them from an Ophiotaurus by taking the form of another such creature and then draining its love. Having bonded over their hatred of the ponies, the three worked together to reach the summit, where Cozy convinced Chrysalis to let Tirek drain her magic with the promise that he would return it. She did so, but reacted with horror upon realizing that the three were starting to become friends; she quickly put a halt to such thoughts, and convinced the others to join her in hiding the bell rather than returning it to Grogar.

While Grogar was distracted seeking an alternative power source for his plans, Chrysalis and her comrades attempted to wield the bell's power with no success. Cozy, remembering Twilight's mention of the Canterlot Archives, convinced the other two to join her in traveling there to look for information. Upon reaching Canterlot, they found Canterlot Castle under increased security and the Last Summer Sun Celebration underway. Chrysalis quickly realized that the confusion could be used to their advantage, and adopted both her Unicorn form of Crackle Cosette and the guise of a royal guard to sow dissension. She and her comrades succeeded in retrieving a book about the bell, while also noting the ease with which they had been able to cause division between the ponies.

War on Equestria
Chrysalis and her allies escalated their efforts to sow distrust between, Unicorns, and , while Tirek sought out the spell that would allow them to access the bell's magic. Having done so, the three split its magic between them, resulting in all three undergoing transformations. In their enhanced forms, they ambushed Grogar as he returned from an expedition, destroying an amulet he had brought back. They then turned the Bewitching Bell's magic against him, and in the process discovered that it was not really Grogar, but Discord. After a failed attempt by Cozy Glow to master his Chaos Magic-and betray her two partners-the trio returned it to the bell before setting out on their final operation.

Chrysalis made her way to the School of Friendship in Ponyville to confront Starlight Glimmer, seeking vengeance for her previous loss to the Unicorn. Starlight met Chrysalis and then teleported them both to a frigid mountain range, seeking to keep her away from the school's evacuating students. The pair then engaged in a heated contest, unleashing blasts of magic at each other as they moved about the slopes. Starlight managed to bring an avalanche down on Chrysalis, but the former queen's enhanced power allowed her to escape and stun Starlight in the process. Encasing her fallen foe in a cocoon, Chrysalis eagerly anticipated prolonging Starlight's suffering as they departed.

Chrysalis then joined Tirek and Cozy Glow in Canterlot, breaking into the throne room of Canterlot Castle and quickly overpowering Twilight Sparkle and her allies. They then revealed the extent of their plans to the beleaguered heroes, and prepared to destroy Twilight by combining their powers. However, 's interference freed Twilight, who made her escape as the others held the three villains back as long as they could. Chrysalis and her allies added them to their growing collection of prisoners, which also included Starlight and the Pillars of Old Equestria. Chrysalis was particularly gratified to enhance their cells-which she evidently produced material for-with the shards of her Queen Chrysalis' throne throne, which had been used to reinforce the castle's security.

At Cozy Glow's suggestion that she be allowed to absorb the magic the villains had captured in the Bewitching Bell again, the trio fell to bickering. Tirek reminded them that they still had no way to control Discord's magic, and thus refused to allow the use of the Alicorn Magic taken from the Two Sisters. Discord offered to instruct them in exchange for his friends being spared, but used the ruse to break Starlight out of her cell. She swiftly freed the other prisoners, and Chrysalis and her teammates were forced to contend with her, Discord, the Princesses, and the Pillars while Twilight's closer friends made their escape. They soon defeated and reimprisoned them, only to be confronted with a new-or more accurately, very old-dilemma: the Windigos.

Chrysalis was all for allowing the Windigos to ravage Equestria before dealing with them, while Tirek insisted that they be eliminated immediately. However, the Mane Six and Spike then appeared outside Canterlot to face the villains, who opened a portal to face them once and for all. Chrysalis briefly found herself distracted by the logic-defying antics of, but realized that her friends were after the Bewitching Bell the villains had brought with them. She then attacked Rarity, whom she overpowered despite briefly being checked by the Unicorn mare and Spike. Unfortunately, Chrysalis then captured the young dragon and forced the others to surrender or see his wings torn from his body.

With their foes subdued, Chrysalis and her allies launched a joint attack to destroy them, only for a magical barrier to inexplicably appear to defend them. To the surprise of the three villains, an army of Equestria's allies-including Chrysalis' own former subjects-charged into battle against them. The onslaught caught the three off guard, but their immense power enabled them to repulse their assailants. However, Twilight prevented the trio from mounting a counterattack, and declared her recognition of the true power of the Magic of Friendship. Channeling this magic with the aid of her friends, the Pillars, and the Young Six, she unleashed it against Chrysalis and the others, who were stripped of their stolen powers.

Despite this loss, Chrysalis remained defiant, promising that she and her allies would continue to seek vengeance-only to be flattened by a giant cupcake falling out of the sky. This proved to be courtesy of Pinkie Pie, who had captured the Bewitching Bell; Discord swiftly reclaimed his magic from her and returned Celestia and Luna's. The three then confronted Chrysalis' humiliated alliance, and at Discord's suggestion cast a Stone Sleep spell upon them. Realizing what was happening, Chrysalis made a last ditch lung, but was fully fossilized before she could move far enough away. Their defeat was later covered in a story in an Equestrian newspaper.

Personality
Despite her defeats, Chrysalis easily became overconfident, dismissing Tirek's concerns that Twilight Sparkle could still pose a threat to them.
