Queen Chrysalis is the changeling Queen. She appears in My Little Pony: Friendship is Magic and serves as the main antagonist of Season 2's two-part finale "A Canterlot Wedding", as well as the comic series The Return of Queen Chrysalis set after Season 2. She is a shapeshifter who took on the form of Princess Cadance in order to invade Canterlot by taking Cadance's place and render her husband-to-be, Shining Armor, unable to perform his duties as Captain of the Royal Guard. She then returned in The Return of Queen Chrysalis 2 to help Brendan, Dave & Brendan's minions kill Twilight & Spike.
A Canterlot Wedding
Chrysalis first makes an appearance in "A Canterlot Wedding - Part 1," disguised as Princess Cadance. Sometime before the episode takes place, when the Princess was going to marry Twilight's brother Shining Armor, Queen Chrysalis imprisoned her and took her form, becoming more powerful by feeding off Shining Armor's love for her, and making him unable to perform his duties as a royal guard.
When the main six arrive from Ponyville to help with the wedding plans, she shows disinterest both in Twilight and everything else set up for the wedding. When Twilight figured out that she was evil, and confronted her, she secretly imprisoned Twilight in the caves below Canterlot.
The next episode "A Canterlot Wedding - Part 2," begins with Chrysalis, still in Cadance's form, taunting Twilight and telling her that she's using Shining Armor for her own ends. Twilight and the real Cadance, also imprisoned by the Changeling Queen, find each other. Eventually, they escaped and confronted Chrysalis, who then revealed her true form, for the first time.
She then tells everyone of her intentions and plan to siege Canterlot, and managed to defeat Celestia, thanks to the power of Shining Armor's love and imprison her in a cocoon. Her minions, the changelings, were then able to break through the barrier (which Shining Armor projected due to Chrysalis's earlier threats) and invade Canterlot, with plans to invade the rest of Equestria afterwards.
Twilight and her friends tried to get to the Elements of Harmony, but were captured by the changelings before reaching them. The episode ends with Shining Armor, no longer under the Queen's control, using the power of Cadance's love to unleash an energy explosion that sent all the changelings, including Chrysalis, flying into the distance.
The Return of Queen Chrysalis 2
In "The Return of Queen Chrysalis 2", Queen Chrysalis and her Changelings was revealed to have survived their fall and landed in Brendan's Empire.
